1. Temperature sensor off from the holder

Correct temperature detection can control the air conditioner

2. To loosen screws makes controller trouble

,especially Heat-Sink part

Check Point In ServiceCheck Point In Service

RA 1 Group - 55 -

3. Always putting silicon grease

on the surface between Power semiconductor and heat-sink

Also putting insulation mica on non insulated power semiconductor.

4. Confirm POWER OFF and LED OFF

before Connecting / Dis-Connecting BLDC FAN socket.

Connecting / Dis-connecting of BLDC FAN SOCKET can make

Damage to both PCB assy and BLDC FAN MOTOR (9K/12K model).

This cause troubles like fire, reset trouble, etc.

5. Make sure to connect power wire tightly

to the terminal block screw and OUTLET (power plug).

6. Make sure not to take of the seals stuck on Case Control

for making air flow through controller cool the heat-sink.

AIR FLOW

Into heatsink

7. KEEP CLEAR around air inlet of indoor unit.

Blocking air flow cause HIGH-LOAD CONDITION and error occurs

because of protecting inverter controller especially in heating

mode.
