ECSS E3335-20

1. Qualification: All refrigeration and electrical maintenance, service, and repair must

be performed by a Certified Technician that is trained in the required flammable

refrigerants safety procedures. Technicians must read the entire section

“REFRIGERATION WARNINGS SECTION” of this manual.

Including but not limited to the following:

a) breaking into the refrigerating circuit.

b) opening of sealed components.

c) opening of ventilated enclosures.

2.Checks to Area: Prior to beginning work on systems containing FLAMMABLE

REFRIGERANTS, safety checks are necessary to ensure that the risk of ignition is

minimized prior to conducting work on the system.

-Capacitors are discharged: this shall be done in a safe manner to avoid possibility of

sparkling.

- No live electrical components and wiring are exposed while charging, recovering or

purging the system.

- Continuity of earth bonding.

ECSS E3335-20

-Work shall be undertaken under a controlled procedure to minimize the risk of a

flammable gas or vapor being present while the work is being performed.

-All maintenance staff and others working in the local area shall be instructed on the

nature of the work being carried out. Work in confined spaces shall be avoided.

-The area shall be checked with an appropriate refrigerant detector prior to and during

work, to ensure the technician is aware of potentially toxic or flammable atmospheres.

Ensure that the leak detection equipment being used is suitable for use with all

applicable refrigerants, i.e., non-sparking, adequately sealed, or intrinsically safe.

-If any hot work is to be conducted on the refrigerating equipment or any associated

parts, appropriate fire extinguishing equipment shall be available on hand. A dry

chemical or CO2 fire extinguisher should be adjacent to the charging area.

-No person carrying out work in relation to a REFRIGERATING SYSTEM which

involves exposing any pipe work shall use any sources of ignition in such a manner that

it may lead to the risk of fire or explosion. All possible ignition sources, including

cigarette smoking, should be kept sufficiently far away from the site of installation,

repairing, removing and disposal, during which refrigerant can possibly be released to

the surrounding space. Prior to work taking place, the area around the equipment shall

be surveyed to make sure that there are no flammable hazards or ignition risks. “No

Smoking” signs shall be displayed.

-Ensure that the area is in the open or that it is adequately ventilated before breaking

into the system or conducting any hot work. A degree of ventilation shall continue during

the period that the work is carried out. The ventilation should safely disperse any

released refrigerant and preferably expel it externally into the atmosphere.

-Where electrical components are being changed, they shall be fit for the purpose and

to the correct specification so as to minimize the risk of possible ignition due to incorrect

parts. At all times, the manufacturer’s maintenance and service guidelines shall be

followed. If in doubt, consult the manufacturer’s technical department for assistance.

The following checks shall be applied to installations using flammable refrigerants:

a) the actual REFRIGERANT CHARGE is in accordance with the room size within

which the refrigerant containing parts are installed.

b) The ventilation machinery and outlets are operating adequately and are not

obstructed.

c) Markings of the equipment continue to be visible and legible. Markings and signs

that are illegible shall be corrected.

d) Refrigerating pipes or components are installed in a position where they are

unlikely to be exposed to any substance which may corrode refrigerant containing

-Repair and maintenance to electrical components shall include initial safety checks and

component inspection procedures. If a fault exists that could compromise safety, then

no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If

the fault cannot be corrected immediately but it is necessary to continue operation, an

An adequate temporary solution should be used. This shall be reported to the owner of

the Initial safety checks shall include:

ECSS E3335-20

3. Repairs to sealed components

-During repairs to sealed components, all electrical supplies shall be

disconnected from the equipment being worked upon prior to any removal of sealed

covers, etc. If it is necessary to have an electrical supply to equipment during

servicing, then a permanently operating form of leak detection shall be located at the

most critical point to warn of a potentially hazardous situation.

-Particular attention shall be paid to the following to ensure that by working on

electrical components, the casing is not altered in such a way that the level of protection

is affected. This shall include damage to cables, excessive number of connections,

terminals not made to original specification, damage to seals, incorrect fitting of glands,

etc. Ensure that the apparatus is mounted securely.

Ensure that seals or sealing materials have not degraded to the point that they no

longer serve the purpose of preventing the egress of flammable atmospheres.

Replacement parts shall be in accordance with the manufacturer’s specifications.

-Do not apply any permanent inductive or capacitance loads to the circuit without

ensuring that this will not exceed the permissible voltage and current permitted for the

equipment in use.

NOTE The use of silicon sealants can inhibit the effectiveness of some types of leak

detection equipment. Intrinsically safe components do not have to be isolated prior to

working on them.

4. Detection of flammable refrigerants: Under no circumstances shall potential

ignition sources be used in the searching for or detection of refrigerant leaks. A halide

torch (or any other detector using a naked flame) shall not be used.

The following leak detection methods are deemed acceptable for all refrigerant

systems:

-Electronic leak detectors may be used to detect refrigerant leaks but, in the case of

FLAMMABLE REFRIGERANTS, the sensitivity might not be adequate or might need

recalibration. (Detection equipment shall be calibrated in a refrigerant-free area.)

Ensure that the detector is not a potential source of ignition and is suitable for the

refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of

the refrigerant and shall be calibrated to the refrigerant employed, and the appropriate

percentage of gas (25 % maximum) is confirmed.

-Leak detection fluids are also suitable for use with most refrigerants but the use of

detergents containing chlorine shall be avoided as the chlorine can react with the

refrigerant and corrode the copper pipework.

NOTE Examples of leak detection fluids are

– bubble method,

– fluorescent method agents.

If a leak is suspected, all naked flames shall be removed/extinguished.

If a leakage of refrigerant is found which requires brazing, all the refrigerants shall be

recovered from the system, or isolated (by means of shut off valves) in a part of the

system

ECSS E3335-20

remote from the leak.

5. Removal and Evacuation: When breaking into the refrigerant circuit to make

repairs-or for any other purpose-conventional procedures shall be used. However, for

flammable refrigerants it is important that the best practice be followed, since

flammability is a consideration. The following procedure shall be adhered to:

a. Safely remove refrigerant following local and national regulations.

b. Purge the circuit with inert gas.

c. Evacuate (optional for A2L).

d. Purge with inert gas (optional for A2L).

e. Open the circuit by cutting or brazing.

The refrigerant change shall be recovered into the correct recovery cylinders if venting

is not allowed by local and national codes. For appliances containing flammable

refrigerants, the system shall be purged with oxygen-free nitrogen to render the

appliance safe for flammable refrigerants. This process might need to be repeated

several times. Compressed air or oxygen shall not be used for purging refrigerant

systems. For appliances containing flammable refrigerants, refrigerant purging shall be

achieved by breaking the vacuum in the system with oxygen-free nitrogen and

continuing to fill until the working pressure is achieved, then venting to atmosphere, and

finally pulling down to a vacuum (optional for A2L). This process shall be repeated until

no refrigerant is within the system (optional for A2L). When the final oxygen-free

nitrogen change is used, the system shall be vented down to atmospheric pressure to

enable work to take place. Ensure that the outlet for the vacuum pump is not close to

any potential ignition sources and that ventilation is available.

6. Charging procedures: In addition to conventional charging procedures, the following

requirements shall be followed.

a. Ensure that contamination of different refrigerants does not occur when using

charging equipment. Hoses or lines shall be as short as possible to minimize the

amount of refrigerant contained in them.

b. Cylinders should be kept in an appropriate position according to the instructions.

c. Ensure that the REFRIGERATING SYSTEM is earthed prior to charging the system

with refrigerant.

d. Label the system when charging is complete (if not already).

e. Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM.

7. Decommissioning: Before carrying out this procedure, it is essential that the

technician is completely familiar with the equipment and all its details. It is

recommended good practice that all refrigerants are recovered safely. Prior to the task

being carried out, an oil and refrigerant sample shall be taken in case analysis is

required prior to re-use of recovered refrigerant. It is essential that electrical power is

available before the task commences.

a. Become familiar with the equipment and its operation.

b. Isolate the system electrically.

c. Before attempting the procedure, ensure that:

i. Mechanical handling equipment is available, if required, for handling refrigerant

cylinders.

ii. All personal protective equipment is available and is being used correctly.

iii. The recovery process is supervised at all times by a competent person.

iv. Recovery equipment and cylinders conform to the appropriate standards.

ECSS E3335-20

d. Pump down the refrigerant system, if possible.

e. If a vacuum is not possible, make a manifold so that refrigerant can be removed from

various parts of the system.

f. Make sure that the cylinder is situated on the scales before recovery takes place.

g. Start the recovery machine and operate in accordance with instructions.

h. Do not overfill cylinders (no more than 80% volume liquid charge).

i. Do not exceed the maximum working pressure of the cylinder, even temporarily.

j. When the cylinders have been filled correctly and the process completed, make sure

that the cylinders and the equipment are removed from the site properly and all isolation

valves on the equipment are closed off.

k. Recovered refrigerant shall not be charged into another refrigerating system unless it

has been cleaned and checked.

8. Labeling: Equipment shall be labeled stating that it has been de-commissioned and

emptied of refrigerant. The label shall be dated and signed. For appliances containing

flammable refrigerants, ensure that there are labels on the equipment stating the

equipment contains flammable refrigerant.

9.Recovery: When removing the refrigerant from a system, either for servicing or

decommissioning, it is recommended good practice that all refrigerants are removed

safely.

When transferring refrigerant into cylinders, ensure that only appropriate refrigerant

recovery cylinders are employed. Ensure that the correct number of cylinders for

holding the total system charge is available. All cylinders to be used are designated for

the recovered refrigerant and labeled for that refrigerant (i.e., special cylinders for the

recovery of refrigerant). Cylinders shall be complete with pressure-relief valve and

associated shut-off valve in good working order. Empty recovery cylinders are

evacuated and, if possible, cooled before recovery occurs.

The recovery equipment shall be in good working order with a set of instructions

concerning the equipment that is at hand and shall be suitable for the recovery of all

appropriate refrigerants including, when applicable, FLAMMABLE REFRIGERANTS. In

addition, a set of calibrated weighing scales shall be available and in good working

order. Hoses shall be complete with leak-free disconnect coupling and in good

condition. Before using the recovery machine, check that it is in satisfactory working

order, has been properly maintained and that any associated electrical components are

sealed to prevent ignition in the event of refrigerant release. Consult manufacturer if in

doubt.

The recovered refrigerant shall be returned to the refrigerant supplier in the correct

recovery cylinder, and the relevant waste transfer note arranged. Do not mix

refrigerants in recovery units and especially not in cylinders.

If compressors or compressor oils are to be removed, ensure that they have been

evacuated to an acceptable level to make certain that FLAMMABLE REFRIGERANT

does not remain within the lubricant. The evacuation process shall be carried out prior

to returning the compressor to the suppliers. Only electric heating to the compressor

body shall be employed to accelerate this process. When oil is drained from a system, it

shall be carried out safely.

Condensate Pump Standard

The pump is mounted in the base compartment and is designed to automatically

remove the condensate water that collects from defrosting the evaporator coil. The

pump has a built-in tank that collects water from the evaporator coil defrost cycle. When

the pump tank is full the pump switches on and pumps water to a remote location for

disposal. When the tank is empty the pump automatically switches off.

The pump is capable of lifting water to a maximum of 20’.

Condensate Discharge Hose.

The case is provided with a 25’ of 3/8ID clear flexible tubing. Depending on options it is

either coiled up on top of the case or in the base compartment.

Hose Coiled in Base

Disconnect Power: Access the hose located in base compartment by removing one

of the base side panels. The hose can be routed to the nearest remote drain through

one of the provided openings or holes Do not run hose in heavy traffic areas and be

sure hose does not get kinked or pinched.

Hose Coiled on Top

Hose coiled on top of the unit is designed to be run vertical to the ceiling before

being routed to the nearest remote drain. The maximum vertical height the hose can

run is 20’ from floor. Once the hose turns to a horizontal direction the hose must

have a downward slope to avoid low spots that water can collect. Be sure the hose

does not get kinked or pinched.

ECSS E3335-20

Condensate Evaporator Pan Shipped Loose (OPTION)

If the optional high output condensate pan was ordered it will be shipped loose in a

separate box. This high output pan must be field mounted and wired by a licensed

electrician.

If there is already a factory condensate pan and mounting brackets installed in the base

compartment they must be removed before installing the optional high output pan.

Unwire the heater wires from the 2x 4 electrical box and cap remaining wire ends with

UL approved wire nuts. NOTE: THESE WIRES CAN NOT BE CONNECTED TO THE FIELD

INSTALLED HIGH OUTPUT PAN.

Mount the high output condensate pan inside the base

compartment so that the (2) condensate drain tubes drain

directly into the pan as shown in photo.

The field installed high output condensate pan must be wired

to its own designated circuit breaker and cannot be wired into

the same circuit breaker that the display case uses. The

display case circuit and wiring are not sized to handle the

extra amperage of the high output condensate pan.

See label on condo pan for proper circuit sizing.

- Bottom Electrical (standard): There is cord and plug provided on the high output

Refrigerant Detection and Mitigation System

The refrigerant detection system (RDS) shuts down the operation of the refrigerator

when a leak is detected. The system is comprised of 2 or more sensors, a low voltage

power supply, 1-2 safety shutoff solenoid valves, and 1-2 refrigerant check valves.

When a leak is detected by one of the sensors, the internal sensor relay opens to shut

off the safety solenoid valve(s). The refrigeration check valve prevents any back flow

from the rest of the external system from entering the unit that would further contribute

to a leak.

Please note that once a leak is detected and the flow of refrigerant is stopped, the

display case will stop cooling, and any temperature sensitive products must be removed

from the unit.

This display case’s fans are a part of the leak mitigation system and are required to

remain powered on as long as there is power to the display case. In the event of a

refrigerant leak, the unit’s fans are required to run to reduce the concentration of

flammable refrigerant in and around the unit. When replacing gas detection sensors,

only replace with the original model of sensor provided by Federal.

To replace a faulty sensor, simply remove unplug the electrical quick connection and

unscrew the sensor fasteners and attach the new sensor to the original sensor location

in the original orientation.

After replacing installing the new sensor, power on the display case. After a few

seconds, the sensor light will begin to blink green. See illustration above. The

refrigeration system will be allowed to run as normal.

The sensor is capable of a long life and will monitor its condition to ensure functionality.

If the sensor’s self-monitoring system detects an issue it will go into a fault state and

shut off the flow of refrigerant to the appliance. See above illustration for fault indication

on LED.

The gas inlet exposes the sensing element of the sensor to surrounding gases. The

opening in the sensor housing exposes the humidity and temperature sensors inside the

sensor to the environment and makes them susceptible to pollutants such as volatile

ECSS E3335-20

chemicals, acids, bases, cleaning and foaming agents. Exposure to those pollutants

should be avoided. Cleaning products might damage the sensor or temporarily block its

gas inlet, inhibiting or delaying the response to the refrigerant.

The use of solvent emitting materials near the sensor, such as PVC cement glues, may

lead to nuisance trips. Solvent emitting materials can lead to high concentrations of

volatile gas in the nearby environment. The gas sensor may sense these

concentrations, and trigger a system mitigate response. Please note that the safety

shut-off valve system is installed at the factory. No safety shut-off valves are required to

be installed in the field on new equipment.

Powering on control

To turn refrigeration control power on, press and hold for approx. five seconds. The

display will read “On” while the button is depressed. When the control powers on, the

display will read the current set point numbers 1 thru 9. The compressor run

indicator will illuminate on the display, meaning that the compressor is running.

(Note: the control may already be in the on mode when shipped from factory).

To turn refrigeration control power to off, press and hold for approx. five seconds.

The display will read “Off” while the button is depressed. When the control powers off

the display will flash back and forth between the current set point and “Off”. The

compressor run indicator will be off on the display. When refrigeration control is in

the off-mode cabinet lights and evaporator fans will still operate, but the compressor

will not turn on causing the case to gradually reach room temperature.

Adjusting the set point

The set point is what determines how cold the display case will hold food and

beverage. To adjust the set point press and hold the button approx. 5 seconds

until the display begins to flash a number. Then press the use the button to scroll

number up (colder) or press the button to scroll number lower (warmer). There

are nine (9) available set point numbers, the higher the number of the set point, the

colder the display case will run, with setting “9” being the coldest and setting “1” being

the warmest. Once you have chosen your desired setting press the button again

to confirm your choice.

Entering manual defrost mode

ECSS E3335-20

To initiate a manual defrost press and hold the button approx. 5 seconds. The

control will read “dEF” while the button is being held. The defrost is initiated when the

defrost mode indicator illuminates on the display. The control display will then

return to reading the set point. when the defrost mode indicator turns off the defrost

is complete and the compressor will turn back on illuminating the compressor run

indicator .

Error codes

It is possible for error codes to be displayed on the control screen. In the event of a

malfunction an alarm will sound and the alarm indicator will be displayed on the

display. An error code or codes will flash intermittently on the display. If there are

multiple codes, the display will continuously cycle through them. The following photo

shows error code “E0” as an example.

Mute: You may mute the alarm by pressing and releasing the wrench button. The red

ringing bell and all error codes will still be displayed. When the fault is remedied the

control will return to normal operation and will automatically clear the codes from the

display.

CONTROL OPERATION

Electronic Control

This unit is equipped with an electronic temperature control. The control parameters are

set at the factory and cannot be manually changed in the field. Control parameter

changes can only be made by downloading a new set of parameters via a program chip

supplied by Federal Industries.

Operation

The control uses two sensors, one located in the air stream and one located on the

evaporator coil. The sensor located in the air stream is referred to as the temperature

control sensor. The sensor located on the evaporator coil is referred to as the coil

sensor.

The temperature control sensor is located inside the center tower at the top. The sensor

location is critical for proper operation on the unit. Do not move or relocate this sensor.

The coil sensor is strapped to the evaporator coil. This sensor location is critical for

proper operation of the unit. Do not move or relocate this sensor.

The temperature control is set to cut in at 39 degrees F. The Temp control cuts out at

14 degrees F at the coldest setting “9” and 28 degrees F at the warmest setting, ‘1’ on

the control display.

The temp control turns off the refrigeration system when you “press and hold” the top

arrow / power button for approx. 3 seconds until “OFF” flashes on display.

Defrost Cycle

The CAREL control is programmed to initiate defrost via two different methods. There

are 3 programmed defrost cycles in the case which will initiate a defrost cycle every 8

hours. The unit does not have a time clock so the defrost cycles cannot be set for any

specific time of day.

The unit also has an ‘On demand’ defrost feature that will initiate a defrost when the

temperature differential between the evaporator temperature and the air temperature is

more than 15 degrees for 5 minutes after 30 minutes into the refrigeration cycle.

Do not use other means to accelerate the defrosting cycle process other than those

recommended by the manufacturer.

Maximum Run Timer

The unit is equipped with a maximum run timer that is preset at the factory for 75

minutes on. If the temperature control does not reach cut out set point after running for

one hour, the timer will turn the compressor off for a minimum of 2 minutes.

installation. Case must be installed as per the installation section of this manual to

provide proper condensing air cooling.

Dual Pressure Control (Self-Contained Models Only)

The dual pressure control is used as a safety device and is factory set. The pressure

control works on a differential. The low-pressure side is a safety to protect the

compressor in the case of refrigerant loss. The high-pressure side is a safety to protect

from system failure causing too high of system pressure. As of 8/1/14 ECSS60 only has

integrated dual pressure control on condensing unit.

The high side of the pressure control is factory set to 400psi and is not

adjustable. Low side setting for the R454c cases are set at 40psi differential for

the cutout and 60psi for the cut-in.

Self-Contained Refrigeration Operation

The unit temperature is controlled by the Electronic control and timers outlined in the

Drier filter most be installed in field for proper operation. Electronic control runs identical

ECSS E3335-20

to the Self-Contained models except the electronic control opens and closes a

refrigeration solenoid valve located on the suction line instead of turning on and off a

compressor. The solenoid valve closes and shuts off the refrigeration flow to the unit

and initiates a pump down cycle. This will allow the remote low-pressure switch to open

and shut off remote compressor.

The condensing unit and pressure controls are optionally supplied from the factory for

remote location installation. The condensing unit must be mounted and wired by the

installer. The high low-pressure switch must be wired in series with the compressor

power supply as shown in diagram below.

Remote Condensing Unit Installation

1. Mount condensing unit as close as possible to the remote display case as practical.

Follow condensing unit manufacturer guidelines for proper piping and distance

requirements.

2. All refrigeration and/or electrical materials between the condensing unit and display

case are to be supplied by installing contractor.

3. Route properly sized and designed refrigeration lines from the condensing unit to the

cabinet.

Horizontal suction lines should be pitched downward towards the condensing unit at

least ½” per 10’ run to aid the oil drainage. A “P” trap must be installed in the suction

line at the foot of every riser to insure oil return. Dry nitrogen must be used to flow

through tubing while brazing refrigeration lines.

4. Suction line must be insulated the entire length with Armaflex (or equivalent). Do not

run liquid line inside insulation with suction line.

5. The remote high/low-pressure control must be mounted, wired and set pressures by

the installer.

6. Leak check condensing unit, cabinet, and all connecting tubing. Cabinet and

condensing unit tubing should be checked to insure no leaks occurred during

shipping or from rough handling.

Make certain all refrigeration valves are opened and evacuate system to 500

microns. Charge the system with refrigerant type specified on the data plates.

Electronic Expansion Valve (EEV)

A traditional TXV uses springs and a temperature bulb to open and close a valve port

that controls the flow of refrigerant entering the evaporator coil. An electronic expansion

valve (EEV) controls the refrigerant flow much more precisely, increasing the

performance and efficiency of the refrigeration system. The EEV controls the flow of

Refrigerant by opening and closing the valve port based on the response to signals sent

to the EEV by an electronic controller. The electronic Control bases these signals by

processing information provided from a temperature sensor and pressure transducer

located on the discharge side of the evaporator coil.

These sensors monitor the evaporator superheat and protects the compressor from any

liquid flood back under low superheat conditions.

EEV Controller Settings

The electronic expansion valve controller also allows the use of different types of

refrigerants without the need to change the expansion valve.

The controller is set from the factory to run on 449A refrigerant and will not need any

changes to the control unless another refrigerant is used.

Note: Check your State and Local regulations for approved refrigerants for your

install location. Federal Industries is not liable for any alternate refrigerants used.

The control is located on the left side of the case.

Note: Never change any of the other setting other than the refrigerant type. It may

also be necessary to change the superheat setting only when using a different

refrigerant.

MAINTENANCE

IMPORTANT: Read this Section of this manual located on page 5.

“REFRIGERATION WARNING &INSTALLATION-REPAIR-DECOMMISSIONING”

All refrigeration and electrical work must be performed by certified technicians.

Cleaning Condenser Coil

NOTICE: Condenser coil or optional air filter must be cleaned a

minimum of twice per month to insure proper refrigeration

performance and prevent compressor failure. In some

environments, it may be necessary to clean more frequently.

FAILURE TO CLEAN CONDENSER COIL WILL VOID

COMPRESSOR WARRANTY.

It is very important that the Condenser coil or optional air filter is cleaned twice

per month to insure proper refrigeration performance and to prevent compressor

failure. In some environments, it may be necessary to clean more frequently.

Failure to clean condenser coil will void condenser warranty. This procedure is

for Self-Contained models. The remote condenser coil must also be cleaned at

same intervals.

1. Disconnect power to the unit.

2. On ECSS40 Remove the nose panel and on ECSS60 remove the side panel on

left side of case next to the controls.

Carefully vacuum the front surface of condenser coil. Take care not to bend coil

fins with vacuum cleaner nozzle.

-If equipped with optional air filter remove filter and carefully vacuum the front

surface of condenser coil. Take care not to bend coil fins with vacuum cleaner

nozzle. Wash filter using warm soapy water, rinse, and let dry. Apply a generous

coat of filter coat adhesive to both sides of filter. (Filter coat adhesive is available

through any restaurant supply distributor.) Recommended Super Filter Coat

NOTE: Failure to coat filter with a fresh coat of filter adhesive after

cleaning will prevent filter from working properly. Failure to do so

will allow the condenser coil to plug, which will affect refrigeration

performance and could cause compressor failure.

3. Reinstall side panel(s).

Pre-Service Checklist

You may avoid the cost and inconvenience of an unnecessary service call by first

reviewing this checklist of frequently encountered situations that can cause

unsatisfactory case performance.

CAUTION: Before servicing case, turn off power at the main breaker of fuse

box.

Case Does Not Operate

Check for disconnected power supply.

Check for tripped breaker on blown fuse.

Check that the thermostat display is on and that the green indicator light

is lit.

Lights Do Not Operate

Check that power switch & light switch is on.

Check for tripped breaker or blown fuse.

Check that light housing cords are plugged in correctly to sockets in the

tower

Case Temperature Too Warm

Check that the cold air inlet and outlet slots are not blocked.

Check for a blocked or dirty condenser coil.

Check for cold airflow. Lack of adequate cold airflow could indicate a

defective evaporator fan or a blocked evaporator coil. Check that paper or

foreign materials are not blocking evaporator. If the evaporator coil is

blocked due to excessive frost, put into manual defrost. Excessive frost

can buildup overtime if the case is set too cold or if there is excessive

humidity in the store.

Check all the fans in the evaporator compartment and tower are running.

Case Sweating Note: Some interior sweating is normal on this case.

Check room ambient – Case is designed to operate in an environment not

to exceed 75ºF and 55% relative humidity.

Check all the fans in the evaporator compartment and tower are running.

Overflow of Condensate Pan

Check that drain in bottom of tub floor is not plugged.

Check that drain trap to the condensate pan is not plugged

Overflow of Optional Condensate Pump:

Check that drain in bottom of tub floor is not plugged.

Check that drain trap to the condensate pan is not plugged

Check that drain lines from pump is not plugged or pinched.

Check to see that pump float is operating correctly.

Verify that pump is plugged in and has power.

Replace pump if still not pumping condensate.

Special Service Situations

IMPORTANT: Read this Section of this manual located on page 5.

“REFRIGERATION WARNING &INSTALLATION-REPAIR-DECOMMISSIONING”

All refrigeration and electrical work must be performed by certified technicians

There are rare occasions when the refrigerant charge must be evacuated from a

case to perform service work. In those situations, Federal Industries

recommends that the refrigerant charge be evacuated into a recovery system to

prevent the possibility of hydrofluoro olefin (HFO) from being released into the

atmosphere.

The release of HFO into the atmosphere is a potential source of global warming.

Note the condensing unit that was supplied with this case has a receiver tank

large enough to hold all the charge you may be able to pump down the system

when service is required.

If moisture or liquid is observed around or under a Federal Industries case, an

immediate investigation should be made by qualified personnel to determine the

source of the moisture or liquid. The investigation made should determine if the

case is malfunctioning or if there is a simple housekeeping problem.

Moisture or liquid around or under a case is a potential slip /fall hazard for

persons walking by or working in the general area of the case. Any case

malfunction or housekeeping problem that creates a slip / fall hazard around or

under a case should be corrected immediately.
