Check Point In Service
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
Inverter TF
- 90 -

91.

3. Always putting silicon grease
on the surface between Power semicondoctor and heatsink
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).
5. Make sure the tight power wire connection
to the terminal block screw and OUTLET (power plug).
This cause troubles like fire, reset trouble, etc.
Inverter TF

92.

6. Make sure the Seal
because of keeping air flow of controller heatsink cooling.
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.
