Electric Supply

Supply voltage requirement is on the cabinet serial plate.

Low or high voltage can detrimentally affect the refrigeratio unit and it is recommended to use the electric socket only for the refrigerator.

Grounding

To prevent shock and fire hazards, be suretherefrigerator is properled.

Clearance

Refrigerators require a minimum clearance of 7 inches between the back of the cabinet and the wall

Ventilation

Refrigerators demand a sufficient amount of cool clean air.

Keep the refrigerator away from sunlight and other hert and moisture generating equipment such as stoves, oven, dishwashers, etc.

Floor

Be sure the floor where you intend to install the refrigerator is strong enough to support the total weight of the refrigreator and its contenes.

Level

To provide adequate drainage and proper door operation, is necessary that the refrigerator be level. this xhould be done after the refrigerator is set in its final operation positio

When servicing

Turn the power off at the main power box(mains) before opening the unit to check or repair electrical parts and wiring.

Keep your fingers and clothing away from any moving parts.

Clean up the site sfter you finsh, remembering to check that no metal scraps or bits of wiring have been left insid the unit being serviced.

OTHERS

Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with or heat, can produce dangerously toxic gas

Confirm upon completing installstion that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room hester or other heat source, it can produce dangerously toxic gas.

Wash hands after handing

Handling the cord on this product or cords associated with aaccessories sold with this product, will expose you to lead a chemical known to the State of Dalifornia to caner, and birth defects or other repoductive harm.

PCB Operation Method Each Mode

1. The common value setting method

1) "A ON/OFF & B ON/OFF" are power switch for each cabinet.

2) "TEMP.SET" makes you to set the temperature value in all cabinet.

3) "SELETION" makes you to choose the cabinet that you want when you set a value.

4) "UP&DOWN" makes you to adjust every commom value.

5) Hold pushing the "TEMP.SET" button for five seconds, it can be available to set the common value of control.

2. Common value of Control

Temperature deviation adjustment(0°~9°F) value "H".

To adjust different measurement between on PCB and thermo sensor due to wire length.

Defrosting time setting (1~60 minutes) value "d".

Defrost heater turn off setting (37°F~90°F) value "t".

Compressor delay time setting (1~15 minutes) value "C".

Automatic defrosting period setting (every1~24 hours) value "P".

Compressor turn on deviation adjustment(1~20°F) value "o".

Each value can be adjust ed by UP & DOWN button.
