54. Correct temperature detection can control the air conditioner
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
- 54 -

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).
5. Make sure to connect power wire tightly
to the terminal block screw and OUTLET (power plug).
This cause troubles like fire, reset trouble, etc.
- 55 -

56. 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.
