CABINET LOCATION: An air space of at least 2” must be maintained on all sides of the refrigerators. Do
not install this refrigerator in a warm unventilated room that exceeds 80oF; do not place refrigerator in
direct sunlight; do not place refrigerator under or near heat range or heating vent.
CABINET LEVELLING: The refrigerator has to be completely leveled side to side and front to back or
slightly tilted front to back but never tilted forward. Once the refrigerator is placed in its final location,
use a carpenter level to level the refrigerator. Proper leveling of the refrigerator is important for the
door closing.
INSTALLATION INSTRUCTIONS
WARNING
This refrigerator MUST be installed on a dedicated grounded circuit protected with a 15 Amp circuit breaker
or a 15 Amp time delay fuse. Do not remove ground prong. If the cord or plug is damaged, replace with the
same type. Refrigeration and electrical work must be performed by a qualified technician. Failure to follow
these instructions can result in death, fire, or electrical shock.
• DO NOT USE AN EXTENSION CORD
• DO NOT CUT, REMOVE OR BYPASS THE GROUNDING PRONG FROM THE PLUG
• DO NOT PLUG INTO AN OUTLET CONTROLLED BY A WALL SWITCH
• ENSURE POWER CORD IS NOT CUT OR DAMAGED FROM PINCHING, KNOTTING, OR MISHANDLING
NOTICE:
Failure to follow these instructions may void the warranty and/or cause loss of product.
POWER REQUIREMENTS: The refrigerator requires a 15 Amp dedicated and properly grounded
115V circuit with a NEMA 5-15P receptacle. Wiring should be sized according to the amperage
rating stated on the serial plate. Failure to use a dedicated circuit may cause the circuit breaker
to trip off and/or cause voltage drops. As a result, power to the refrigerator may be inter-
rupted and freezing performance can be adversely affected which may cause equipment
damage and/or product loss.
Voltage supply to the refrigerator must not vary more than ±10% of the nominal voltage, or performance may
be affected. The warranty does not cover damage resulting from excessive voltage variations.
NEMA 5-15P
Metallic Clip Shelf
The clips can be removed at any time if a new position is chosen for the shelf or basket. To remove, grab
the clip with your thumb and index finger, then push up the slanted surface until the clip is free. A slight
hit upwards to the slanted surface is usually an easy way to remove the clip. Once the clips are in place,
put the shelf on top. Once the shelves are securely in place, baskets (if equipped) may be positioned on
the shelves.
The refrigerator is supplied with shelves and metallic clips. The refrigerator has slotted pilasters to
position the shelves according to the customer’s needs.

ambient temperature too high.
• Clogged condenser
• Adjust control setting (See page 4).
• Follow instructions for product
loading (See page 3)
• eep at least 2” free space around all
sides of the refrigerator. Room temp-
erature is recommended not to exceed
80˚F. Make sure the air flow to the
compressor is not obstructed.
• Clean the condenser (See page 7)
WARNING
Make sure the refrigerator is disconnected from the power supply before any service. Press the
refrigerator switch to the “Off” position then unplug the power cord from electrical receptacle.
All service work must be conducted by a certified technician only.

Once the refrigerator has been installed and the power supply has been connected, push the refrigerator
switch to ON (see page 4). The compressor will start to run after 6 minutes. This can be confirmed by
listening for a slight humming or a slight vibration.
Once the refrigerator is running, the inside temperature will start to cool down within a couple of min-
utes. Ensure that the refrigerator has reached the desired temperature (this will take between 2 to 3
hours) by checking the electronic control display readout before loading product. It is strongly rec-
ommended to run the refriger tor empty for 24 hours before lo ding ny products.
NOTE:
If the refrigerator is running and the power supply is interrupted, the refrigerator will not restart
immediately. There is a 6 minute delay for compressor protection.
OPERATING INSTRUCTIONS
WARNING
Check with your power company if you are not certain of your power supply.
Before connecting to power supply the refrigerator should be upright and idle for at least 1 hour.

The electronic controller can detect and signal several alarm conditions: high/low refrigerator tempera-
tures, door open and open or short-circuited temperature probes. If the alarm conditions last longer than
pre-programmed time delays, the controller will turn ON an audio signal (buzzer). Also a LED light located
in the upper left corner of the controller, next to the caution symbol, will glow in case an alarm is active.
Once the alarm conditions have been fixed, the controller will turn off the alarms on its own. Alarms can
be disabled by pressing any controller button, during alarm conditions

1. To clean the condenser grille at the back, use a vacuum cleaner, or compressed air, or a brush.
Go over the entire grill and remove any dust that may be on the grill surfaces or stuck between
welded wires.
2. Prior to cleaning the pre-condensers that are located just below the fan blade in the compressor
compartment, turn the power switch off and unplug the power cord. Feed a vacuum hose, or
compressed air hose through the compressor platform slots underneath the pre-condensers.
Clean all pre-condenser surfaces by going through all of the bottom openings and reaching the
whole height up to the fan blade(s).
3. When finished with cleaning, plug the power cord into receptacle then turn the power switch on.
NOTE:
The cleaning of the condenser is a service not covered under the warranty
The refrigerator is designed for minimal condenser cleaning. With the “lint free” condenser design,
most dust and dirt will pass right through the condenser. To insure the proper operation, we recom-
mend scheduled check-ups and cleaning every three to four months. This period may be shorter or
longer depending on the location in which the refrigerator was installed. A dirty condenser can result
in a voided warranty, part failure, product loss, and higher electrical cost. The steps to clean the con-
denser are as follows:

GENERAL
The refrigerator should be cleaned at regular intervals to meet a good standard of hygiene
and to keep the refrigerator attractive as an effective point of purchase display.
INTERIOR CLEANING
Use only mild non-abrasive liquid cleaner, water and a soft cloth for the entire refrigerator
interior. Make sure to wipe off all residue.
EXTERIOR CLEANING
Use only mild non-abrasive liquid cleaner, water and a soft cloth for the painted surfaces and
a stainless steel polish and cleaner for the stainless steel surfaces if desired.
CLEANING GLASS DOOR
Due to the special coating on the glass, use only a mild, non-abrasive liquid cleaner, water,
and a soft cloth. Same applies to the plastic door frame.
CLEANING
WARNING
To reduce the risk of fire, electrical shock or personal injury, disconnect the refrigerator from the
power source before cleaning. Press the refrigerator switch to the “Off” position, then unplug the
power cord from the receptacle. eep liquids away from electrical and electronic components.
To clean the exterior whether it has the original finish or a decal package, use only a mild non-abrasive
liquid cleaner, water and a soft cloth. For stainless steel parts, a commercial stainless steel polish and
cleaner can be used. Always apply the cleaner to the soft cloth and then clean the refrigerator. Never
apply the cleaner directly to the refrigerator. Excess liquid applied to the surface may seep into the elec-
tronic control and switches which can cause an electrical hazard or a malfunction.
DO NOT USE abrasive or caustic cleaners, scouring pads, solvents or flammable liquids.
CAUTION
Do not apply hot water on cold glass components. Allow glass to warm sufficiently to prevent
shattering.
CAUTION
Do not use ammonia or bleach based cleaners or abrasive type cleaners.
Do not use abrasive cleaning pads.
