INSTALLATION
L cati n
Units 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. A fully loaded unit can weigh as much
as 500 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 rear of the unit.
It is important to allow for proper air flow from the rear to the front 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.
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. Prevent obstruction to allow the outlet or inlet of air flow.
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" from any wall
Leveling
A level cabinet looks better and will perform better because the doors will line up with the frames properly.
Use a level to make sure the unit is level from front to back and side to side. Units supplied with legs will
have adjustable bullet feet to make the necessary adjustments. If the unit is supplied with casters, no
adjustments are available. Ensure the floor where the unit is to be located is level.
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 to place. Failure to meet this requirement can cause
compressor failure and unit damage.
Unit repairs will n t be subject t standard unit warranties if due t impr per installati n
pr cedures.
Electrical c nnecti n
Refer to the amperage data on page 3, the serial tag, your local code or the National Electrical Code to be
sure the unit is connected to the proper power source.
The unit must be turned OFF and disc nnected fr m the p wer s urce whenever
perf rming service, maintenance functi ns r cleaning the refrigerated area.

OPERATION
D n t thr w items int the st rage area. Failure t heed these rec mmendati ns
c uld result in damage t the interi r f the cabinet.
Refrigerated cabinets
Temperature range for the internal cabinets is 34°F to 38°F for the chef base refrigerators.
Food Prep units should operate with pans in place. Operating without pans and/or pan covers in place will
lower the efficiency and may damage the unit due to continuous over-use.
Continuous opening and closing of the door will prevent the unit’s ability to maintain optimum refrigeration
temperature.
Defr sting:
Every 6 hours, the unit will turn off so the evaporator coil can defrost. The controller now displays the
defrost symbol. When the coil temperature reaches the terminal temperature or after 20 minutes of defrost,
the unit will turn on.

MAINTENANCE
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
Cleaning solutions need to be alkaline based or non-chloride based. Any cleaner containing chlorides will
damage the protective film of the stainless steel. Chlorides are commonly found in hard water, salts, and
household and industrial cleaners. If cleaners containing chlorides are used, be sure to rinse and dry
thoroughly.
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 steels
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.
Never use an acid based cleaning s luti n！
！！
！Many f d pr ducts have an acidic c ntent
which can deteri rate the finish. Be sure t clean the stainless steel surfaces f ALL
f d pr ducts.
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 as this can cause them to become brittle and prevent proper seals. Do not
use sharp tools or knives to scrape or clean the gasket which could possibly tear the gasket and rip the
bellows.
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.
D rs/Hinges
Over time and with heavy use, door hinges may become loose. 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 to both the doors and the door hinges.
Drain Maintenance
Each unit has a drain located inside the unit which removes the condensation from the evaporator coil and
evaporates it into an external condensate evaporator pan. Each drain can become loose or disconnected
from moving or bumping the drain. If you notice excessive water accumulation on the inside of the unit, be
sure the drain tube is connected from the evaporator housing to the condensate evaporator drain pan. If
water starts to collect underneath the unit, you may want to check the condensate evaporator drain tube to
be sure it is still located inside the drain pan. The leveling of the unit is important as the units are designed to
drain properly when on a level surface. If your floor is not level this can also cause drain problems. Be sure
all drain lines are free of obstructions because this may cause water to back up and overflow the drain pans.
