Page 8 of 48

3. 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.

4.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 the possibility of sparkling.

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

system.

- Continuity of earth bonding.

-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.

Page 9 of 48

-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:

Page 10 of 48

5. 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.

8. 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

remote from the leak.

Page 11 of 48

9. 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.

10. 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.

11. 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.

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.

Page 12 of 48

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.

12. 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.

13.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.

5.6 REFRIGERATION SYSTEM

Self-Contained Models

The self-contained models are shipped from the factory with a completely operational refrigeration

system and require no modifications or adjustments upon 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.

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

Low side setting for cases are set at 40psi differential for the cutout and 60psi for the cut-in.

Remote Models

The remote models are shipped from the factory with the evaporator coil, expansion valve, sight glass,

service valves and refrigerant solenoid valve. Installation must be performed by a licensed

Refrigeration Technician. See the Service section of this manual for installation requirements.

Electronic Expansion Valve (EEV) After 1/20 On Remote Cases Only

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.

Page 18 of 48

Instead of using heat energy to remove condensate run off from the evaporator coil a condensate pump

moves the water to a nearby drain.

 The Condensate Pump is provided with 50ft of clear 1/2in OD x 3/8in ID tubing that must be run out of

the base area to a drain.

 There are several drain tube exit locations provided in the base as noted in the drawing above. Plugs or

caps will need to be removed in the desired exit location.

 The hose can be run the entire 50ft in any direction as required, but no higher than 20ft from the

pump base. A check valve is provided in the pump to prevent water from flowing back into the

reservoir. For best efficiency extend the hose level below the level of the pump base to create a

siphoning effect. Never run the hose to or through an area below freezing (32°F, 0°C) or freezing water

will block the tube.

16.2 SPECIAL SERVICE INSTRUCTIONS

IMPORTANT: Read this Section of this manual located on page 7.

“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 in order 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 hydrofluorocarbons (HFC’s) from being released into the

atmosphere.

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.

16.3 ELECTRONIC CONTROL OPERATION

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. The preset control parameters are listed on the chart in the

Settings Chart below.

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 defrost probe.

The temperature control sensor is located on the plastic tub behind the evaporator coil on the

centerline of the display case in the cold air stream. 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 38°F (3.3°C). The Temp control cuts out at 16°F (-8.9°C) at

the coldest setting (“9”) and 28°F (-2.2°C) at the warmest setting (“1”).

See “11.2 Using the electronic control” on page 29 for more details on using the control.

Defrost Cycle

The 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 12°F (6.7°C) for

5 minutes after 30 minutes into the refrigeration cycle (e.g. if the air stream probe measures 32°F/0°C

or greater and the defrost probe measures 20°F/-6.7°C or lower for five minutes). Once initiated the

defrost cycle will terminate when evaporator coil sensor reaches 45°F (7.2°C).

If a manual defrost is required, one can be initiated by pressing and holding the down arrow for three

(3) seconds. This is typically unnecessary and should only be performed if special circumstances require

it.

16.5 REFRIGERATION OPERATION

Self-Contained Models

The self-contained models are shipped from the factory with a completely operational refrigeration

system and require no modifications or adjustments upon installation. Case must be installed as per

the installation section of this manual to provide proper condensing air cooling.

The unit temperature is controlled by the electronic control outlined in the control section of this

manual.

Note: The condenser fan runs continuously.

The remote models are shipped from the factory with the evaporator coil, expansion valve, sight glass, and

refrigerant solenoid valve. Filter Drier must be installed in field. Electronic control runs identical 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

1. Mount condensing unit indoors as close to the remote display case as practical. The refrigeration line

should be as short as possible and must not exceed 30 feet.

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.

4. 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.

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

inside insulation with suction line.

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

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

should be checked to ensure no leaks occurred during shipping or from rough handling.

8. Make certain all refrigeration valves are opened and evacuate system to 500 microns. Charge the

system with refrigerant type specified on the data plates.
