2. Installation Instructions

Location: The location of the meat freezer should be away from extreme heat and

cold. A minimum of 2 inches clearance should be allowed around the freezer to facilitate
adequate airflow to the compressor.

Leveling: In order to provide adequate condensate drainage, it is imperative that the
unit be level. The floor where the unit is located should be level.

Caution: The refrigeration system is designed to operate in ambient temperatures of no

more than 100°F.

Pre-Installation Instructions

Inspection: Upon receipt, examine the equipment carefully for any damage. If
damage has occurred, notify the carrier and H&K immediately.

Unpacking: Remove the unit from the plastic wrap and untie the electrical cord by
removing the holding tape. It is recommended that the unit remain crated until it has
reached the installation location.

Plug: For international markets, the installer must install the plug on the power cord of
the unit before the unit can be operated.

3. Instructions for Use

Power Source: Insert the plug of the freezer into a standard 120V AC 60 Hz. 15A

outlet. The unit consists of one compressor. Other motors and heavy appliances
should not be used on the same circuit with the freezer.

Start-Up: The freezer is turned “ON” by plugging the cord into the outlet. Check if the
thermostat on the front is “ON”. Let the unit run for 1 hour before placing product in the
freezer.

Temperature Setting: The unit has been tested at the factory and the thermostat has
been set to maintain a temperature between -10°F and 0°F.

Thermostat Adjustment: If the unit does not hold the desired temperature, the
thermostat can be adjusted. To adjust thermostat, press the upper or lower button for 2
seconds and release. The set point will start blinking. Using the upper or lower button,
adjust the temperature set point to the desired setting. Once the desired setting has
been selected, do not touch any button and the controller will accept the new set point.
Wait for 1 hour before readjusting the thermostat. Excessive tampering with the
thermostat may lead to service difficulties.

The unit can be forced into a manual defrost by pressing the lower button for more than
5 seconds. When the defrosting is initiated, the display will show DEF. Defrosting can
be canceled again by pressing the push-button once more and the thermostat will return
back to normal mode. When the defrost cycle is finished, the display will return to
normal operation. This feature should be used when the coil freezes up due to
excessive door openings and/or high humidity.

Note: When the unit comes out of defrost it will display a higher temperature for a short

period of time, this is not the actual temperature in the freezer but the temperature
inside the evaporator housing.

Condensate Disposal: The Grill Side Freezer does not require a floor drain, it has a
built in condensate pan in the base of the condensing unit.

Caution: Do not leave the self-closing rolling cover open for an extended period of
time.

Caution: Excessive tampering with the temperature controller may lead to operating

difficulties.

4. Cleaning

Exterior Cleaning: The exterior of the unit should be cleaned with a soap and water

mixture and sanitized. Do not use abrasive cleaners to clean the exterior of the cabinet

using a soft sponge and a soap-water mixture.

Caution: Use of abrasive pads to clean the unit will result in scratching and spoiling

the finish of the unit. Refer to the GSF PM card for cleaning

instructions before cleaning the unit.

5. Preventative Maintenance

should be cleaned and vacuumed every 3 months. The back and side grills are
designed to be removable for this purpose.

before cleaning the condenser fins and fans on the unit.
