INSTALLATION
1. Inspection: Upon receipt, examine the equipment carefully for any damage. If damage
has occurred, notify the carrier and H&K immediately..
2. Unpacking: Remove the unit from the plastic wrap and untie the electrical cord by re-
moving the holding tape. It is recommended that the unit remain crated until it has
reached the installation location.
3. Location: The location of the freezer should be away from extreme heat and cold.
Enough clearance should be allowed around the freezer to facilitate easy closing and
opening of the sliding cover.
4. 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.
OPERATING PROCEDURE
1. Power Source:Insert the plug of the freezer into a standard 120V AC 60 Hz. Outlet.
The unit consists of one compressor. Other motors and heavy appliances should not be
used on the same circuit with the freezer.
2. Start-Up: The freezer is turned ON by plugging the cord into the outlet and check if the
condenser fan is running. Let the unit run for 1 hour before placing product in the
freezer.
3. Temperature Setting: The unit has been tested at the factory and the thermostat has
been set to maintain a temperature between –10 and 0°F (-23.3 and –17.7°C).
4. Thermostat Adjustment: If the unit does not hold the desired temperature, the thermo-
stat can be adjusted. For colder temperatures, turn knob clockwise one number at a time.
For warmer temperature setting, turn knob anti-clockwise one number at a time.

Wait for 1 hour before readjusting the thermostat. Excessive tampering with the thermo-
stat may lead to service difficulties.
5. Condensate Disposal: The condensate from the freezer is disposed via a drain at the bot-
tom of the freezer.
CAUTION: Do not leave the freezer cover open for extended period of time.
MAINTENANCE
1. Exterior Cleaning:The exterior of the unit should be cleaned with a soap and water
mixture. Do not use abrasive cleaners to clean the exterior of the cabinet as this might
damage the stainless steel finish. Do not use steel wool or any strong chemicals.
2. Interior Cleaning:The anodized aluminum interior of the freezer can be cleaned using
a soft sponge and a soap-water mixture. The pilasters can be removed without tools to
aid in cleaning the interior.
3. Condenser: For proper operation of the condensing unit the condenser fins and fans
should be cleaned and vacuumed every 3 months. The front grill is designed to be re-
movable for this purpose.
