UNDER-COUNTER REFRIGERATORS AND FREEZERS
INTRODUCTION
This manual covers the Under-counter Refrigerators and
Freezers. Please read this manual completely before at-
tempting to install or operate this equipment.
Site Preparation
The installation site must be cleaned and prepared prior
to the equipment delivery.
• Refer to the SPECIFICATIONS and have a licensed
electrician conrm that all electrical requirements
are satised.
• Conrm that all ooring is structurally strong enough
to support the weight of a fully loaded unit; a fully
loaded unit can weigh as much as 1500 pounds.
Consult with a structural engineer for conrmation if
there is any reason to doubt the oor strength.
• Conrm that adequate ventilation has been provid-
ed, and that the unit will not be located close to a
heat source.
• For all units on casters, conrm that the oor is level
where the unit is to be located.
RECEIVING AND INSPECTING
Exercise care to prevent damaging the equipment dur-
ing unloading and on-site transporting.
1. Visually inspect the exterior of the package, skid
and/or container. Report any damage to the carrier
immediately.
2. If any packaging damage is noted, open and inspect
the contents with the carrier.
3. If concealed damage is discovered after unpacking
the equipment notify the carrier. Notication must
be made both in writing and verbally.
4. Check the compressor compartment housing and
visually inspect the refrigeration package. Conrm
that the lines are secure and the base is intact.
5. Request the required damage forms and an equip-
ment damage inspection by the shipping company.
The inspection should be performed within 10 days
from receipt of the equipment.
6. Retain all crating material until an inspection has
been performed or waived.
Serial Number Location
The serial number of all self-contained refrigerators and
freezers is located inside the unit on the left hand side
near the top on the wall. Have the serial number avail-
able when calling for parts or service.

UNDER-COUNTER REFRIGERATORS AND FREEZERS
INSTALLATION
Location
All units are intended for indoor use only. A fully loaded
unit can weigh as much as 1500 pounds. Choose a loca-
tion with a level oor strong enough to support the total
weight of a fully loaded unit. Reinforce the oor if neces-
sary.
For the most efcient refrigeration, provide good air cir-
culation around the unit.
Inside cabinet
Do not pack the unit interiors so that air circulation is im-
peded. The refrigerated air is discharged at the top rear
of the unit. Allow for proper air ow from the top rear to
the bottom of the unit. Obstructions to this air ow can
cause evaporator coil freeze ups and loss of temperature
or overow of water from the evaporator drain pan. The
shelves have a rear turn up on them to prevent obstruc-
tions to the rear air ow. However, bags and other items
located at the rear of the cabinet may obstruct the air
ow.
Outside cabinet
Be sure that the unit has access to ample air ow. Avoid
hot corners and locations near stoves and ovens. Do not
install the unit closer than two inches from a wall. To pre-
vent air obstruction, do not locate large boxes and/or tall
stacks of product that might obstruct the air exhaust or
the air inlet.
CAUTION
If the unit is laid on its side or back for any reason,
allow a minimum of 24 hours in the upright position,
beforestart-uptoallowcompressoroiltoowback
to the sump. Failure to meet this requirement can
cause compressor failure, unit damage, and will
void the unit warranties.
Electrical connection
Refer to the amperage data provided in the SPECIFI-
CATIONS, the serial tag, the local electrical code and/or
the National Electrical Code. Have a licensed electrician
conrm that the facility wiring is adequate for the unit and
that a protected circuit of the correct voltage and amper-
age is provided for each unit. Conrm that the unit is
connected only to the proper protected power source.
DANGER
TURN THE ON/OFF SWITCH TO OFF AND
DISCONNECT THE UNIT FROM THE POWER
SOURCE WHENEVER PERFORMING SERVICE,
MAINTENANCE FUNCTIONS OR CLEANING
THE UNIT.
Leveling
Level the cabinet to improve performance, to better align
the doors, to reduce uneven strain on the cabinet and
reduce movement of the contents on the shelves. Use a
level to level the unit from front to back and side to side.
Units supplied with legs have adjustable bullet feet to
make the leveling adjustments. If the unit is supplied with
casters, no leveling adjustments are available. Ensure
the oor is level, where the casters unit is located.
Stabilizing
Casters are provided for convenience, ease of cleaning
underneath and for mobility. Install the unit on a level sur-
face, in a stable condition and lock the front wheels to
prevent movement.

UNDER-COUNTER REFRIGERATORS AND FREEZERS
OPERATION
Refrigerated Cabinets
The internal temperature range for all under-counter
refrigerators is 33°F to 40°F. The internal temperature
range for under-counter freezers is -3°F to -7°F. Open-
ing and closing the door must be minimized to allow the
unit to maintain optimum refrigeration temperature.
Defrosting
Every 6 hours, the unit turns off and the controller dis-
plays the defrost symbol. This allows the evaporator
coil to clear the ice. When the coil temperature reaches
the terminal temperature (or after 20 minutes) the unit
re-starts.
On/Off Switch
The on/off switch is located on the front of the bottom
shroud. When the unit is on, the green LED is on.
Front Panel Controls and Indicators
The front panel controls and indicators are used to set

MAINTENANCE
DANGER
TURN OFF THE POWER SWITCH AND
DISCONNECT THE UNIT FROM THE POWER
SOURCE WHENEVER PERFORMING SERVICE/
MAINTENANCE FUNCTIONS AND/OR
CLEANING THE REFRIGERATED AREA.
Refrigerators and Freezers
Clean the interior and exterior using soap and warm wa-
ter. If this is not sufcient, use ammonia and water or a
nonabrasive liquid cleaner. When cleaning the exterior,
always rub with the stainless steel grain to avoid marring
the nish.
Do not use an abrasive cleaner, it may scratch the stain-
less steel and/or the plastic. Abrasive cleaners can also
damage the breaker strips and gaskets.
Cleaning the Condenser Coil
Clean the condenser coil a minimum of every 90 days.
If there is a large amount of debris, dust or grease ac-
cumulation prior to the 90 day cycle, reduce the cleaning
cycle to every 30 days.
If the buildup on the coil consists of only light dust and
debris, clean the condenser coil using a brush. For
heavier dust buildup, use a vacuum or compressed air.
If heavy grease is present use a refrigeration degreas-
ing agent designed specically for the condenser coils.
Spray the condenser coil with degreasing agent and
blow through with compressed air.
Failure to maintain a clean condenser coil can initially
cause high temperatures and excessive run times. Con-
tinuous operation with dirty or clogged condenser coils
may result in compressor failures. Neglecting the con-
denser coil cleaning procedures will void any warranties
associated with the compressor.
CAUTION
Never use a high pressure water wash for this
cleaning procedure as water can damage the
electrical components located near or on the
condenser coil.
Stainless Steel Care and Cleaning
Stainless steel contains 70-80% iron which will rust. It
also contains 12-30% chromium which forms an invis-
ible passive lm over the steel’s surface that acts as a
corrosion shield. As long as the protective layer remains
intact, the metal remains stainless. If the lm is broken
or contaminated, outside elements can break down the
steel and begin to form rust or discoloration.
To properly clean stainless steel, use soft cloths or plas-
tic scouring pads.
CAUTION
Never use steel pads, wire brushes or scrapers to
clean stainless steel surfaces.
Cleaning solutions must be alkaline based or non-chlo-
ride cleaners. Any cleaner containing chlorides will dam-
age the stainless steel protective lm. 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.
Perform routine stainless steel cleaning with soap and
water. Extreme stains or grease should be cleaned with
a non-abrasive cleaner and plastic scrub pad (rub with
the grain). There are also stainless steel cleaners avail-
able which can restore the protective layer and preserve
the nish.
Early signs of stainless steel breakdown may consist of
small pits and cracks. If these early signs are present,
clean thoroughly and apply a cleaner specically de-
signed for stainless steel cleaners to attempt to restore
the passivity.
CAUTION
Never use an acid based cleaning solution. In
addition, many food products have an acidic
contentwhichcandeterioratethenish.Besure
to clean the stainless steel surfaces of all food
products. Common acidic based food items
include; tomatoes, peppers and other vegetables.

UNDER-COUNTER REFRIGERATORS AND FREEZERS
Gasket Maintenance
Gaskets require regular cleaning to prevent mold and
mildew buildup and to maintain the gasket elasticity.
Clean gaskets with warm soapy water. Avoid full strength
cleaning products on gaskets, this can cause the gaskets
to become brittle and prevent proper sealing. Never use
sharp tools or knives, which could tear the gasket and/or
rip the bellows, to scrape or clean the gasket.
Gaskets are easy to replace and do not require the use
of tools. To remove and replace the Dart style gasket, pull
the gasket out of the groove in the door and press the
new gasket back into place.
Doors/Hinges
Over time the door hinges may become loose. 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. Tighten the screws that mount the
hinge brackets to the frame of the unit. If this does not
solve the issue call a qualied service agent.
Drain Maintenance
The drain located inside all of the units removes the
condensation from the evaporator coil and evaporates
it at an external condensate evaporator pan. Moving or
bumping the drain may cause the drain to become loose
or disconnected. If excessive water accumulates on the
inside of the unit make sure the drain tube is connected
from the evaporator housing to the condensate evapora-
tor drain pan. If water has collected underneath the unit,
check the condensate evaporator drain tube to be sure it
is still located inside the drain pan. Leveling the unit is im-
portant because the units are designed to drain properly
when level. If the oor is not level drain problems may oc-
cur. Be sure all drain lines are free of obstructions. Food
products blocking drain lines is a common cause of water
back up and overow.
Door Replacement and Adjustment
1. Open the door until it remains open, about 100° to
110°.
2. Loosen and remove the bottom screw on the self-
closing cartridge. Remove the three hinge screws,
then slide the door down and out.
3. To prepare a new door, rotate the square head of the
cartridge shaft approximately 120° in the direction
the door closes. This action preloads the hinge and
it is now ready to be secured to the bottom hinge.
4. From the closed position, hold the door at about
100°, insert the bottom hinge over the square shaft
of the cartridge so that the hinge is facing the cabi-
net. Once positioned, insert and fasten the mounting
screw.
5. Maintain the door/hinge assembly at about 100°
and slide it up to the top hinge pin. Conrm proper
alignment, and then fasten the bottom hinge.
6. The door must swing closed by itself with no restric-
tion. Conrm that the door swings freely.
Open the Bottom Shroud
Loosen and remove the screw from the two holes in front of
the bottom shroud, the bottom shroud can be moved out.
