IMPORTANT SAFEGUARDS (cont.)
Electrical Connection
Do not, under any circumstances, cut or remove the third (ground) prong from the power cord. For personal safety, this
appliance must be properly grounded. The power cord of this appliance is equipped with a 3-prong grounding plug that
mates with a standard 3-prong grounding wall outlet to minimize the possibility of electric shock hazard from the
appliance. Have the wall outlet and circuit checked by a qualified electrician to make sure the outlet is properly grounded.
The appliance should always be plugged into its own individual electrical outlet which has a voltage rating that matches
the rating label on the appliance. This provides the best performance and also prevents overloading house wiring circuits
which could cause a fire hazard from overheated wires. Repair or replace immediately all power cords that have become
frayed or otherwise damaged. Do not use a cord that has been crimped, shows cracks or has frayed insulation abrasion
damage along its length or at either end. When moving the appliance, be careful not to damage the power cord.
Power Surges
Connecting the unit to the incorrect voltage or oversized circuit protection (i.e. a breaker rated for over 20 amps) is not
covered by the appliance warranty. Neither is a damaged power cord, using unauthorized electrical components and/or
modifying the units wiring.
It is recommended that the appliance circuit doesn’t incorporate either a GFI breaker or outlet.
Any complications created by use of a GFI are not covered by the unit’s warranty as they are prone to inadvertently
tripping off to often.
Refrigerant Disposal
If you are throwing away your old appliance it may have a cooling system that uses “Ozone Depleting” chemicals.
Make sure the refrigerant is removed for proper disposal by a qualified service technician.
Appliance Disposal
Follow and comply with all applicable codes and ordinances, cut the plug off the electrical power cord, remove the
door(s) and discard the shelving. This prevents misuse of the unit after its been scrapped.

APPLIANCE INSTALLATION
WARNING
Excessive Weight Hazard
Use two or more persons to move and install appliances.
Failure to do so may result in back or other injury.
Remove Packaging Materials
IMPORTANT:
Do not remove any permanent instruction labels or the data label on your appliance.
• Remove tape and glue from your appliance before using.
• To remove any remaining tape or glue, rub the area briskly with your thumb. Tape or glue residue can also
be easily removed by rubbing a small amount of liquid dish soap over the adhesive with your fingers. Wipe
with warm water and dry with a soft cloth.
• Do not use sharp instruments, rubbing alcohol, flammable fluids, or abrasive cleaners to remove tape or glue.
These products can damage the surface of your appliance.
NOTICE:
LOSS OR SPOILAGE OF PRODUCTS IN YOUR APPLIANCE IS NOT COVERED BY WARRANTY. IN ADDITION TO
FOLLOWING RECOMMENDED INSTALLATION PROCEDURES AFTER ITS BEEN SET IN PLACE, DON’T RUN THE
APPLIANCE 24 HOURS TO LET OIL IN THE REFRIGERANT LINE TO RE-EQUILIBRATE. (DON’T LOAD WITH
PRODUCT UNTIL THE UNIT TEMPERATURE HAS REACHED ITS SET POINT.)
Location Requirements
• Appliances represented in this manual are intended for indoor use only.
• Be sure the location chosen has a floor strong enough to support the total weight of the cabinet and contents as a
fully loaded unit can weigh as much as 1500 pounds.
• Reinforce the floor as necessary to provide for maximum loading.
• For the most efficient refrigeration, be sure to provide good air circulation inside and out.
Inside cabinet:
Do not pack the units so full that air cannot circulate. The refrigerated air is discharged at the top rear of the unit. It is
important to allow for proper air flow from the top rear to the bottom of the unit. Obstructions to this air flow can cause
evaporator coil freeze ups and loss of temperature or overflow of water from the evaporator drain pan. The shelves have
a rear turn up on them to prevent this. However, bags and other items can still be located to the far rear of the cabinet. Air
is brought into the evaporator coil with fans mounted to the front of the coil.
Outside cabinet:
Be sure that the unit has access to ample air. Avoid hot corners and locations near stoves and ovens.
It is recommended that the unit be installed no closer than 2" (51mm) from any wall, a max door swing clearance of 60.5
in. (1537mm) and with at least a 12" (305mm) of clear space above the unit. Adequate air flow (≤86º F) into the utility
compartment is needed to deliver proper performance and extend the appliance life.

Leveling
Ensure the floor where the unit is to be located is level. (It is ok to slope down from front to rear by up to 1/4” – it mustn’t
slope from the rear to the front.
Stabilizing
All models are supplied with casters for your convenience. It is very important, however, that the cabinet be installed in a
stable condition with the front wheels locked while in use. Should it become necessary to lay the unit on its side or back
for any reason, allow at least 24 hours before start-up to allow compressor oil to flow back into place. Failure to meet this
requirement can cause compressor failure and unit damage which isn’t covered by the appliance warranty.
Reversing The Door (Single Door Models Only)
Single door models can be converted from right-hand hinged to left-hand hinged and vice-versa by removing the door
hinges from both the door and unit, reversing their locations and reattaching them, and re-hanging the door upside-down.
NOTICE:
Unit repairs will not be subject to standard unit warranties if due to improper installation procedures or
utilizing an unqualified installer technician to commission the unit.
Electrical Connection
Refer to the amperage data on the Technical Information table, the serial tag, your local code or the National Electrical
Code to be sure that unit is connected to the proper power source.
DANGER
The unit must be turned OFF and disconnected from the power source whenever
performing service, maintenance functions or cleaning the refrigerated area. Failure to
comply may result in Death or Severe Personnel Injury.

OPERATION
Refrigerated cycle
Refrigerators: During the refrigeration cycle, the evaporator fans will run continuously when doors are closed, and the
evaporator fans will stop when one or more doors are open. The door switch will activate the lights when opened on solid
door models only. Glass door models lights are turned on manually using a switch located next to the main power switch.
1. Every 6 hours, the unit will turn off and to allow the evaporator coil to defrost by compressor stop working. The controller
now displays defrost symbol. After 20 minutes of defrost, the unit will turn on again.
2. Anti-condensation heaters on door frames work in conjunction with the compressor.
3. Recommended holding temperature range: 36° to 41°F (2° to 5°C).
4. Comes factory set to 36°F (2°C).
Freezers:During the refrigeration cycle, the evaporator fans will run continuously when doors are closed, and the
evaporator fans will stop when one or more doors are open. Fans will be cycle off during a defrost period. The door switch
will activate the lights when opened.
1. Every 4 hours, the unit will turn off and electric heater will turn on to defrost. The controller now displays the defrost
symbol. When the coil temperature reaches 54°F (12°C) or after 35 minutes of defrost, and after the drip time delay
of 5minutes, the unit will turn on again.
2. Anti-condensation heaters on door frames work in conjunction with the compressor.
3. Recommended holding temperature range: -9° to 9°F (-23° to -13°C).
4. Comes factory set to -6°F (-21°C).
Power Switch:
The power switch is located on the front of the bottom panel. When the unit is on, the switch will glow green.
THERMOSTAT DESCRIPTIONS
Please refer to the additional pages“Digital controller installing and operating instructions”.
TIPS FOR PROPER OPERATION, CLEANING AND MAINTENANCE
1.
The unit should be cleaned daily as well as being tested for the proper holding temperature by measuring the
content temperature and comparing it to the temperature displayed on the controller. They should be within
3°F of each other.
2. When cleaning the exterior surface always use a soft cloth or microfiber towel. If a stiff bristle brush, scouring pad
or scraper is used, the protective chromium oxide barrier will be penetrated allowing the appliance to show signs
of rust.
3. When cleaning the interior or exterior of the appliance always use a mild detergent solution or warm soapy water.
This won’t harm the plastic or metallic substances and will remove most residual surface dust and grime. If a
more aggressive cleaning is needed use a 3M Scotch Brite General Purpose Synthetic Fiber Green Scouring
Pad and a solution of Dawn and warm water or a stainless steel cleaner/polishing product.
4. Ensure your gaskets are making a good compression seal and aren’t torn or damaged as air entering the unit
can increase the appliance’s refrigeration system energy usage. In extreme cases, the temperature could fall
out of range. When changing a gasket, it is recommended that a dab of gasket adhesive be applied every 10 to
12 inches to help hold the gasket in position. This escaping air may cause surface condensation.
5. Do not pack the unit so full that air cannot circulate. The refrigerated air is discharged at the bottom rear of the
unit. It is important to allow for proper air flow from the top rear to the bottom of the unit.
6. Minimize the number of times the appliance door needs to be opened, as frequent access may preclude the
unit’s ability to maintain the proper temperature.
7.
Use shelving with rear and side turn up rails to ensure proper air circulation is maintained as this is needed for
effective, efficient temperature regulation.
8. Never use an infrared thermometer to monitor the unit’s contents bulk temperature as they aren’t accurate for
this application. Use a NIST capable instrument with the right prove and calibrate the thermometer at least 3
times a year using an ice bath. Digital pocket thermometers may be off by as much as 1.8°F when measuring
refrigerated products.
Page 8 of 15
9. For best performance the ambient conditions should be less than 90°F with a relative humidity below 65%.
10.
Ensure the automatic defrost cycle is set to keep the evaporator fan coil free of ice with proper air flow or the unit
won’t maintain the right temperature. The set point for a appliance should be between 35° and 40°F to preserve
the shelf life and freshness of your stored products without needing to worry about a frozen evaporator.
11.
Periodically inspect the displayed appliance temperature and measured steady state product temperature with a
calibrated high-quality digital thermometer. The two readings should agree within 4º F and be below the
recommended product holding temperature established by your operating procedures as well as the model food
code.
12.
The cooling fins are subject to clogging with grease, dust and other particulates even if an air filter is in place.
The cooling fins should be cleaned using a commercial vacuum and if necessary, a degreaser at least 3 times a
year. Do not use a wire or stiff bristle brush to avoid fin damage.
13. Any refrigeration system will generate condensate by cooling the air as it circulates through the appliance. At
least twice a year, the drain line or condensate evaporator, tested to ensure the generated condensate is being
adequality dealt with, and thoroughly cleaned/descaled so the condensate is always properly evacuated from the
appliance.
14. The refrigeration system comes with a controller or thermostat to regulate the cold compartment temperature.
New digital controllers have a differential setting that establishes when the refrigeration system cuts in and out
around the selected set point. A 3° or 4°F differential is recommended for most applications to deliver tight
temperature regulation without short cycling the compressor.
15. Only load the unit with pre-cooled product at temperature, warm product can result in undesired consequences.
16. Jerking on the door to reopen it immediately after it’s been closed (before the internal and external pressures
are again equal) will damage the gasket necessitating its replacement and possibly result in higher holding
temperatures for the appliance due to the continual ingress of warm air.
Page 9 of 15
CLEANING AND MAINTENANCE
DANGER
The unit must be turned off and disconnected from the power source whenever performing
service, maintenance functions or cleaning the refrigerated area. Failure to comply may
result in death or severe personnel injury.
NOTE
Ongoing appropriate preventative & repair maintenance along with cleaning the unit will
preserve its performance, deliver high quality fresher product and extend the appliance life.
Exterior and Interior Cleaning of Appliances
Clean using soap and warm water. If this isn't sufficient, try ammonia or a degreasing detergent (like Dawn) and water or
a nonabrasive multi-surface liquid cleaner (like Formula 409). When cleaning the exterior, always rub with the "grain" of
the stainless steel to avoid marring the finish.
• Do not use an abrasive cleaner because it will scratch the stainless steel and plastic and can damage the breaker
strips and gaskets.
Cleaning the Condenser Coil
Regular cleaning is recommended every 90 days. In some instances, you may find that there is a large amount of debris
and dust or grease accumulated prior to the 90 day time frame. In these cases the condenser coil should be cleaned
every 30 days.
If the buildup on the coil consists of only light dust and debris, the condenser coil can be cleaned with a simple brush.
Heavier dust build-up may require a vacuum or even compressed air to blow through the condenser coil.
If heavy grease is present, there are de-greasing agents available for refrigeration use and specifically for the condenser coils.
The condenser coil may require cleaning with the de-greasing agent and then blown clear with compressed air or CO2.
Failure to maintain a clean condenser coil can initially cause high temperatures and excessive run times. Continuous
operation with dirty or clogged condenser coils can result in compressor failures. Neglecting the condenser coil cleaning
procedures will void any warranties associated with the compressor or cost to replace the compressor.
• For efficient operation, keep the condenser surface free of dust, dirt, and lint.
• We recommend cleaning the condenser coil at least once per quarter more in a greasy/dust environment.
• Clean the condenser with a commercial condenser coil cleaner and a soft brush, available from any
commercial refrigeration equipment retailer, or vacuuming the condenser with a shop vac or use CO2.
CAUTION
Never use a high pressure water wash for this cleaning procedure as water can damage
the electrical components located near or at the condenser coil.
In order to maintain proper refrigeration performance, the condenser fins must be clear of dust, dirt and grease regularly.
It is recommended that this be done at least every three to 4 months. If conditions are such that the condenser is totally
or significantly blocked in three months, the frequency of cleaning should be increased. Clean the condenser with a
vacuum cleaner or stiff brush. If extremely dirty, a commercial-grade condenser cleaner may be required.

CLEANING AND MAINTENANCE (cont.)
Stainless Steel Care and Cleaning
To prevent rust or discoloration on stainless steel several important steps need to be taken. First, one must understand the properties
of stainless steel. Stainless steel contains 70-80% iron which will rust. It also contains 12-30% chromium which forms an invisible
passive film over the steels surface which acts as a shield against corrosion. As long as the protective layer is intact, the metal is still
stainless. If the film is broken or contaminated, outside elements can begin to breakdown the steel and begin to form rust or
discoloration. Treating a surface showing rust with CitriSurf 2310 will help restore the protective chromium oxide layer as well as
removing most of the surface rust when done as soon as any oxidation is noticed. At least every 6 weeks the stainless steel surfaces
should be cleaned and treated with a cleaner/polish product like these stainless steel cleaner and polish offerings such as what
Weiman, 3M 14 oz, Magic and Therapy products. Use of “hard water” with minerals like iron in it must be dealt with immediately (wipe
dry) or the surface may tend to rust Treating the water to soften it is suggested.
CAUTION
Proper cleaning of stainless steel requires soft cloths or plastic scouring pads, never use steel
pads, wire brushes or scrapers! Use a 3M pad or a soft cloth – non-woven fabric works well.
Cleaning solutions need to be alkaline based or non-chloride based. Any cleaner containing chlorides will damage the protective film
of the stainless steel. If cleaners containing chlorides are used, be sure to rinse and dry thoroughly (similar to the use of hard water).
Routine cleaning of stainless steel can be done with soap and water. Extreme stains or grease should be cleaned with a non-abrasive
cleaner and plastic scrub pad. It is always good to rub with the grain of the steel. There are also stainless steel cleaners available
which can restore and preserve the finish of the steel’s protective layer.
Early signs of stainless steel breakdown can consist of small pits and cracks. If this has begun, clean thoroughly and start to apply
stainless steel cleaners in attempt to restore the passivity of the steel.
CAUTION
Never use an acid based cleaning solution! Many food products have an acidic content which can
deteriorate the finish. Be sure to clean the stainless steel surfaces of all food products.
Gasket Maintenance
Gaskets require regular cleaning to prevent mold and mildew build up and also to keep the elasticity of the gasket. Gasket cleaning can
be done with the use of warm soapy water. Avoid full strength cleaning products on gaskets. Do not use sharp tools or knives to scrape
or clean the gasket.
Gaskets can easily be replaced and don’t require the use of tools or authorized service technicians. The gaskets are "Dart" style and
can be pulled out of the grove in the door and replaced by pressing the new one back into place. Do not run the unit long after noticing
the gasket is torn or not sealing – immediately schedule replacing it. Over time gaskets will wear, as such they and other wear parts
are not covered by the appliance warranty.
Doors/Hinges
If the door is beginning to sag, tighten the screws that mount the hinge brackets to the frame of the unit. If the doors are loose or
sagging, this can cause the hinge to pull out of the frame which may damage both doors and door hinges. (It may be necessary to
insert some form of reinforcement if an old door & hinge set becomes loose so it can be tightened without stripping out of the body).
