INTRODUCTION

Thank you for purchasing a Master-Bilt dipping-display cabinet. This manual contains important instructions for installing,

using and servicing your cabinet. A parts list is also included in with this manual. Read all these documents carefully

before installing or servicing your equipment.

CAUTION

This unit uses a flammable refrigerant. Use care when handling and operating to avoid damaging the

refrigerant tubing or increasing the risk of a leak.

All service should be performed by factory authorized personnel. All component parts shall be replaced with

like components to minimize the risk of possible ignition due to incorrect parts or improper service.

This appliance is not intended for use by persons (including children) with reduced physical, sensory or

mental capabilities, or lack of experience and knowledge, unless they have been given supervision or

instruction concerning use of the appliance by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the appliance.

STORE CONDITIONS

Dipping-display cabinets are climate class 8 and are designed to operate in the controlled environment of an air-

conditioned store. An appliance’s climate class designates the ideal temperature range within which it performs best. This

classification makes sure that your appliance keeps food fresh whether you live in a hot or cold climate by assisting you in

selecting one that fits your needs. The store temperature should be at or below 75°F and a relative humidity of 55% or

less. At higher temperature or humidity conditions, the performance of these cases may be affected and the capacity

diminished. It is not uncommon in a newly constructed store for the temperature and humidity to be above design

conditions. These excessive conditions may produce sweating in the case until the store is operational and the ambient

environment is more desirable.

The cabinet should not be positioned where it is directly exposed to rays of sun or near a direct source of radiant heat or

airflow. This will adversely affect the case and will result in poor performance.

If this case is to be located against a wall there should be at least 4” space between the wall and the back of the case.

This space allows for air circulation behind the case, which prevents condensation on the exterior surfaces.

NOTICE

Read this manual before installing your cabinet. Keep the manual and refer to it before doing any service on the

equipment. Failure to do so could result in personal injury or damage to the cabinet.

DANGER

Improper or faulty hook-up of electrical components of the refrigeration units can result in severe injury or death.

NEVER use an extension cord to power this unit. All electrical wiring hook-ups must be done in accordance with all

applicable local, regional or national standards.

NOTICE

Installation and service of the refrigeration and electrical components of the cabinet must be performed by

a refrigeration mechanic and/or a licensed electrician. If the SUPPLY CORD is damaged, it must be

replaced by the manufacturer, its service agent or similarly qualified persons to avoid a hazard.

The portions of this manual covering refrigeration and electrical components contain technical instructions

intended only for persons qualified to perform refrigeration and electrical work.

This manual cannot cover every installation, use or service situation. If you need additional information, call or write the

INSTALLATION INSTRUCTIONS

GENERAL INSTRUCTIONS

1. Be sure the equipment is properly installed by competent service people.

2. Keep the equipment clean and sanitary so it will meet your local sanitation codes.

3. Rotate your stock so that older stock does not accumulate. This is especially important for

ice cream. A "First-In, First-Out" rotation practice will keep the products in good salable

condition.

4. Do not place product in the case when it is soft or partially thawed. Also, product should not be put in the

case for at least 6 hours after it is started.

5. Stock cases as quickly as possible, exposing only small quantities to store temperatures for short

periods of time.

6. When replacing burned out LED, be sure that the electrical power to the lighting circuit is turned off.

NOTICE TO STORE OWNERS / MANAGERS

Moisture or liquid around or under the cabinet is a potential slip/fall hazard for persons walking by or

working in the general area of the cabinet. Any cabinet malfunction or housekeeping problem that creates a

slip/fall hazard around or under the cabinet should be corrected immediately.

If moisture or liquid is observed around or under a cabinet, an immediate investigation should be made by qualified

personnel to determine the source of the moisture or liquid. The investigation should determine if the cabinet is

malfunctioning or if there is a drainpipe leaking.

ELECTRICAL

WARNING

Before servicing electrical components in the case, make sure all power to case is off. Always use a

qualified technician.

NOTICE

For replacement ballast, use only ballast that complies with UL and recommended in part list.

MECHANICAL

Remove grille and check refrigeration lines to see that they are free (not touching each other or

compressor). Spin condenser fan blade to see that it is free.

Check that all service valves are open.The picture below is standard DD series condensing unit. The compressor is

hermetic, it is internally spring mounted and ready to run.

Hermetic Compressors, jelly roll & fin and tube condenser

Remove cabinet from crate base and slide into location. The cabinet must be level from side to side and front to back.

To comply with Sanitation requirements the cabinet must be mounted on legs (6” high min.) or casters or the base

must be sealed to the floor with an N.S.F. listed silicone sealant.

STARTUP

Uncoil the lead cord and pass it through the hole in the grille.

While the cabinet is in operation, check the voltage draw and the amperage draw versus the rating on the

nameplate. Check the voltage at the compressor terminals while the compressor is starting. The unit is designed

to operate at +/- 10% of 115 volts, 60 cycle, single phase. Therefore, the voltage should be between 103 and

126.5 volts.

After the cabinet temperature has pulled down to approximately 0°F at the load line, check the thermostatic control

by turning it to its warmest position. This should shut the compressor off.

A separate 20 amp. fuse circuit for each cabinet is recommended to avoid the possibility of other appliances on a

circuit from overloading and causing a malfunction. Make sure that the electrical service is grounded upon

installation.

REFRIGERANT EVACUATION AND CHARGING

When breaking into the refrigerant circuit to make repairs or any other purpose, use conventional procedures. However, for

flammable refrigerants it is important that best practice be followed, since flammability is a consideration.

Follow this procedure:

• Safely remove refrigerant following local and national regulations

• Purge the circuit with inert gas

• Evacuate (optional for A2L)

• Purge with inert gas (optional for A2L)

• Open the circuit by cutting or brazing

The refrigerant charge 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, refrigerants 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 charge 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.

In addition to conventional charging procedures, follow these requirements:

• 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.

• Cylinders shall be kept in an appropriate position according to the instructions.

• Ensure that the REFRIGERATING SYSTEM is earthed prior to charging the system with refrigerant.

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

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

Prior to recharging the system, pressure test it with the appropriate purging gas. The system shall be leak-tested on

completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.

Punch Mark

TEMPERATURE CONTROL

The dipping-display cabinet has an adjustable temperature control from #1 (warmest setting) to # 9 (coldest

setting). Turn the control knob in line with the punch mark to the desired setting. The temperature control is located

near the condensing unit at the front of the cabinet.

WARMEST SETTING COLDEST SETTING

CLEANING INSTRUCTIONS

WARNING: DO NOT REMOVE FROST WITH A KNIFE, PICK, OR SHARP OBJECTS. DO NOT USE

ABRASIVE CLEANERS OR CAUSTIC CLEANERS OR SCOURING PADS

Every 30 to 60 days (depending on frost accumulation), the cabinet should be emptied, warmed up, and wiped

down using a solution of 1 teaspoon of baking soda with 1 quart of water. This solution will help eliminate odors.

Do not use strong soaps or detergents as they leave odors that can contaminate your product.

Cabinets are equipped with a floor drain that exits out the lower rear. The exit has a convenient garden hose fitting.

If it is not convenient to turn the cabinet power off, lay a piece of plastic sheeting on the floor of the cabinet and

scrape the frost off walls using a plastic scraper. Do not use metal scrapers. This will damage the interior paint of

the cabinet.

LID REMOVAL AND CLEANING

The lid can be removed by lifting up and out (see below). The lid is a high-impact plastic. Wash with warm soapy

water or non-abrasive detergent to avoid scratching.

CAN HOLDER ASSEMBLY REMOVAL AND CLEANING (OPTIONAL)

Remove plastic can clamp by screwing knob off the threaded shaft. Wash the can holder and can clamp with a non-

abrasive detergent to maintain sanitary gloss. Remove the shaft by loosening the wing nut and unscrewing the shaft

from the shelf. Wash the shaft and shelf using a non-metallic brush.

FROST SHIELD REMOVAL AND CLEANING (OPTIONAL)

When the frost-shields accumulate approximately ½ to 1 inch of frost (about two to three days), remove it by lifting

up to disengage from the keyhole slot. Remove the frost by holding under running water until clean. Dry and replace

the frost-shield by engaging screws at the big end of the keyhole and push down.

LID LOCKING KIT INSTALLATION (OPTIONAL)

The optional lid locking kit secures ice cream stored inside the cabinet. One kit is required for each lid.

Follow the process in reverse to disassemble.

TECHNICIAN’S CONSIDERATIONS

Technicians should:

• Have an EPA 608 certification type 1 to work on this cabinet.

• Exercise caution when disconnecting quick-connects or opening refrigerant circuits.

• Use ventilation fans anytime a refrigeration circuit is opened.

• Survey the area for ignition sources before opening a refrigeration circuit.

• Correct all nearby electrical faults and discharge all capacitors before opening a refrigeration circuit.

• Avoid working in confined spaces with A3 refrigerants. Ventilation should be used if necessary.

• Check the area for flammable refrigerants with an approved leak detector to find present refrigerant before starting

work. This leak detection equipment should not be arcing or sparking. It should be intrinsically safe.

• Have a fire extinguisher present during service and installation. A dry chemical or CO

2 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 cigarettes, 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.

Technicians should 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.

Where electrical components are being charged, they shall be fit for the purpose and to the correct specification. At all

times, the manufacturer's maintenance and service guidelines shall be followed. If in doubt, consult the manufacturer's

technical department for assistance.

FLAMMABLE REFRIGERANT CONSIDERATIONS

The following checks shall be applied to installations using FLAMMABLE REFRIGERANTS:

• The actual REFRIGERANT CHARGE is in accordance with the room size within which the refrigerant-containing

parts are installed.

• The ventilation machinery and outlets are operating adequately and are not obstructed.

• If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of

refrigerant.

• Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be

corrected.

• Refrigerating pipes or components are installed in a position where they are unlikely to be exposed to any

substance which may corrode refrigerant containing purpose and to the correct specification. At all times, the

manufacturer's maintenance and service guidelines shall be followed. If in doubt, consult the manufacturer's

technical department for assistance.

CHECKING ELECTRICAL DEVICES

• 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 adequate temporary solution

shall be used. This shall be reported to the owner of the equipment, so all parties are advised.

INITIAL SAFETY CHECKS

• Ensure the capacitors are discharged. This shall be done in a safe manner to avoid possibility of sparking.

• Ensure no live electrical components and wiring are exposed while charging, recovering or purging the system.

• Ensure there is continuity of earth bonding.

During repairs, technicians should ensure all electrical supplies shall be disconnected from the equipment being worked

upon prior to any removal of sealed covers, etc.

LEAK DETECTION

If it is necessary to have an electrical supply to equipment during service, then a permanently operating form of leak

detection shall be located at the most critical point.

Technicians should ensure cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges, or

any other adverse environmental effects. The effects of aging or continual vibration from sources such as compressors or

fans should also be considered.

Under no circumstances shall potential sources of ignition 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.

Examples of leak detection fluids include bubble method and fluorescent method agents.

If a leak is suspected, all naked flames shall be extinguished. If a leakage of refrigerant is found which requires brazing, all

the refrigerant shall be recovered from the system. Removal of refrigerant shall be according to Clause 101.DVS.9 in

UL60335-2-89.

SERVICE INSTRUCTIONS

Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS, safety checks are necessary to

ensure that the risk of ignition is minimized. 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 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. Under no circumstances shall potential sources of ignition 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.

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. 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:

DECOMMISSIONING, SALE AND DISPOSAL

If you sell or give away your dipping cabinet, you must make sure that all safety labels and the installation and service

manual are included with it. If you need replacement labels or manuals, contact the customer service department.

The customer service department should be contacted at the time of sale or disposal of your cabinet so records may be

kept of its new location.

If you sell or give away your cabinet and you evacuate the refrigerant charge before shipment, the refrigerant charge

must be properly recovered in compliance with section 608 of the Clean Air Act, effective November 1995, and in

accordance with all applicable local, regional, or national standards.

Before conducting this procedure, make sure the technician is familiar with the equipment. Prior to the task being

conducted, an oil and refrigerant sample must be taken in case analysis is required prior to re-use of recovered refrigerant.

It is essential that electrical power is available before starting the task.

• Isolate the system electrically.

• Before attempting the procedure, ensure that:

o Mechanical handling equipment is available, if required, for handling refrigerant cylinders

o All personal protective equipment is available and being used correctly

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

o Recovery equipment and cylinders conform to the appropriate standards

• Pump down refrigerant system, if possible.

• If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.

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

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

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

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

• When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the

equipment are removed from site promptly and all isolation valves on the equipment are closed off.

• Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless it has been cleaned and

checked.

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.
