CABINET LOCATION: An air space of at least 2” must be maintained on all sides of the freezers. Do not
install this freezer in a warm unventilated room that exceeds 80oF; do not place freezer in direct sun-
light; do not place freezer under or near heat range or heating vent.
CABINET LEVELLING: The freezer has to be completely leveled side to side and front to back or slightly
tilted front to back but never tilted forward. Once the freezer is placed in its final location, use a carpenter
level to level the freezer. Proper leveling of the freezer is important for the door closing.
INSTALLATION INSTRUCTIONS
• 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.
PO ER REQUIREMENTS: The freezer 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 freezer may be interrupted
and freezing performance can be adversely affected which may cause equipment damage
and/or product loss.
Voltage supply to the freezer 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 freezer is supplied with shelves and metallic clips. The freezer has slotted pilasters to position the
shelves according to the customer’s needs.

slight humming or a slight vibration.
Once the freezer is running, the inside temperature will start to cool down within a couple of minutes.
Ensure that the freezer 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 recommended to
run the freezer empty for 24 hours before loading any products.
NOTE:
If the freezer is running and the power supply is interrupted, the freezer will not restart
immediately. There is a 6 minute delay for compressor protection.

Product loss is not covered under warranty.
OPERATING INSTRUCTIONS
ARNING
Check with your power company if you are not certain of your power supply.
Before connecting to power supply the freezer should be upright and idle for at least 1 hour.
PRODUCT LOADING
DO leave free space in front of the rear vents, from
the vents to the glass door for air circulation.
DO NOT stock any products above or below the load
limit.See load limit labels inside the cabinet for refer-
ence.
DO NOT stock product directly on the bottom of the
inner cabinet. Install the bottom shelf at the lowest
pilaster position prior to stocking.
For proper performance of the unit and to avoid
product spoilage, follow these instructions:
ARNING

The electronic controller can detect and signal several alarm conditions: high/low freezer temperatures,
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

NOTE:
The cleaning of the condenser is a service not covered under the warranty
The freezer 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 recommend
scheduled check-ups and cleaning every three to four months. This period may be shorter or longer
depending on the location in which the freezer was installed. A dirty condenser can result in a voided
warranty, part failure, product loss, and higher electrical cost. The steps to clean the condenser are as
follows:
CONDENSER CLEANING
1. Comp - Indicates compressor status:
Light off - Compressor off
Light on - Compressor on
Light flashing - Start-up delay in progress
2. Def - Indicates defrost status:

4. O - Indicates that no alarms are in progress.
This is the normal mode for the freezer.

Defrost Button
This freezer is designed for automatic defrost. Every eight hours the refrigeration system is turned OFF
and the defrost/drain heaters are activated to melt the ice from the evaporator coil and drain pan. If the
freezer is not leveled properly, the water may not drain out of the freezer, it will re-freeze and ice grad-
ually builds up. Excessive ice buildup reduces cooling performance and may cause the failure of re-
frigeration system and product loss. Ice buildup may be noticed through the evaporator fan grill on the
coil fins.
To perform a manual defrost, follow these steps:
1. Press the UP arrow button and hold it for 6 seconds.
2. Wait until the electronic control stops defrost (the Def LED dot flashes)
3. If ice is still noticeable on the evaporator, press the freezer switch to the “Off” position then
disconnect the freezer from the power supply.
4. Take down the evaporator shroud and use a hair dryer to quickly melt the ice.
5. Make sure the freezer is leveled side to side, and front to back or slightly tilted front to back.
6. Replace the evaporator shroud.
MANUAL DEFROST
GENERAL
The freezer should be cleaned at regular intervals to meet a good standard of hygiene and
to keep the freezer 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 freezer
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
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 freezer. Never apply
the cleaner directly to the freezer. Excess liquid applied to the surface may seep into the electronic con-
trol 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.
ARNING
To reduce the risk of fire, electrical shock or personal injury, disconnect the freezer from the power
source before cleaning. Press the freezer switch to the “Off” position, then unplug the power cord
from the receptacle. eep liquids away from electrical and electronic components.
