INDOOR UNIT

Prepare the proper tools.

Prepare the proper protectors.

Provide adequate ventilation.

After stopping the operation of the air conditioner, turn off the power-supply breaker and remove the power plug.

Discharge the capacitor before the work involving the electric parts.

Do not perform the work involving the electric parts with wet hands.

Do not pour water into the electric parts.

Do not touch the refrigerant.

Do not touch the hot or cold areas in the refrigeration cycle.

When the repair or the inspection of the circuit needs to be done without turning off the power, exercise great caution not to

touch the live parts.

Use the specied refrigerant only

Never use any refrigerant other than that specified.

Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of.

Correct refrigerant is specified in the manuals and on the spec labels provided with our products.

We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by

failure to follow the instructions.

8-1. TIMER SHORT MODE

For service, the following set time can be shortened by bridging the timer short mode point on the electronic control P.C.

board. (Refer to 10-7.)

Set time : 3-minute →3-second (It takes 3 minutes for the compressor to start operation. However, the starting time is

shortened by bridging the timer short mode point.)

NOTE: While the relay 52C is ON, the compressor starting time cannot be shortened.

8SERVICE FUNCTIONS

NOTE:

• The operation settings are memorized when 10 seconds have passed after the indoor unit was operated with the remote

controller.

• If main power is turned OFF or a power failure occurs while AUTO START/STOP timer is active, the timer setting is can-

celled.

• If the unit has been turned OFF with the remote controller before power failure, the auto restart function does not work

as the power button of the remote controller is off.

• To prevent the breaker from tripping OFF due to the rush of starting current, systematize other home appliance not to

turn ON at the same time.

• When some air conditioners are connected to the same supply system, if they are operated before power failure, the

starting current of all the compressors may flow simultaneously at restart.

Therefore, the special counter measures are required to prevent the main voltage-drop or the rush of the starting current

by adding to the system that allows the units to start one by one.

8-2. AUTO RESTART FUNCTION

When the indoor unit is controlled with the remote controller, the operation mode, the set temperature, and the fan speed

are memorized by the indoor electronic control P.C. board. “AUTO RESTART FUNCTION” automatically starts operation in

the same mode just before the shutoff of the main power.

Operation

If the main power has been cut, the operation settings remain.

After the power is restored, the unit restarts automatically according to the memory.

(However, it takes at least 3 minutes for the compressor to start running.)

How to disable “AUTO RESTART FUNCTION”

Turn off the main power for the unit.

Cut the Jumper wire to JR77 on the indoor electronic control P.C. board. (Refer to 10-7.)
