INSTALLATION

Location

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 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.

Should it become necessary to lay the unit on its side or back
for any reason, allow at least 24 hours before start-up so as to
allow compressor oil to flow back to the sump. Failure to meet
this requirement can cause compressor failure and unit

damage.

Unit repairs will not be subject to
standard unit warranties due to
improper installation procedures.

Inside cabinet:

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. Prevent obstruction by
locating large bo
stacks of product to 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, the cabinet will
not be subject to undue strain and the contents of the cabinet
will not move around on the shelves. Use a level to make sure
the unit is level from front to back and side to side. Units

Electrical connection

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. A protected circuit of
the correct voltage and amperage must be run for connection
of the line cord, or permanent connection to the

unit.

The on/off switch must be
turned to OFF and the unit
disconnected from the power
source whenever performing
service, maintenance
functions or cleaning the
refrigerated area.

Stabilizing

All models are supplied with casters for your convenience,
ease of cleaning underneath and for mobility. It is very
important, however, that the cabinet be installed in a stable
condition with the front wheels locked while in use.

OPERATION

Do not throw items into the storage area.
Failure to heed these recommendations could
result in damage to the interior of the cabinet.

Refrigerated cabinets

Temperature range for the internal cabinets is 33°to 40°F for all food prep
units, undercounter and worktop refrigerator; and ,-7°to -3°F for
undercounter and worktop freezers. The rail’s temperature range for all
prep units is 33° to 41°F.

Food Prep units should operate with pans in place. Operated without pans
and/or pan covers in place will lower efficiency and may damage the unit

MAINTENANCE

The power switch must be turned to
OFF and the unit disconnected from the
power source whenever performing
service, maintenance functions or
cleaning the refrigerated area.

Refrigerators and Freezers

The interior and exterior can be cleaned using soap and warm
water. If this isn't sufficient, try ammonia and water or a
nonabrasive liquid cleaner. 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

The condenser coil requires regular cleaning, recommended is
every 90 days.
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 build up 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 a spray with the de-greasing agent
and then blown through with compressed air.

Failure to maintain a clean condenser coil can initially cause high
temperatures and excessive r
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.

In some instances though you may find that there

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.

Stainless Steel Care and Cleaning

To prevent discoloration of rust on stainless steel several
important steps need to be taken. First, we need to 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 f
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 of discoloration.

Proper cleaning of stainless steel requires soft cloths or plastic
scouring pads,

NEVER USE STEEL PADS, WIRE
BRUSHES OR SCRAPERS!

Cleaning solutions need to be alkaline based or non-chloride
cleaners. Any cleaner containing chlorides will damage the
protective film of the stainless steel. Chlorides are also
commonly found in hard water, salts, and household and
industrial cleaners. If cleaners containing chlorides are used be
sure to rinse repeatedly and dry thoroughly upon completion.

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
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

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.
Common items include, tomatoes,
peppers and other vegetables.

In order to maintain proper refrigeration performance, the
condenser fins must be cleaned of dust, dirt and grease regularly.
It is recommended that this be done at least every three months.
If conditions are such that the condenser is totally 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 commercially available condenser cleaner may
be required.

MAINTENANCE
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.
Also, never use sharp tools or knives to scrape or clean the gasket which
could possibly tear the gasket and rip the bellows.

Doors/Hinges

Over time and with heavy use doors the hinges may become loose. If it is
noticed that the door is beginning to sag, it may become necessary to
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 the doors and the door hinges. In some
cases this can require qualified service agents or maintenance personnel.

Drain Maintenance

Each unit has a drain located inside the unit which removes the
condensation from the
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 is collected 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
