CHECK AND TEST 1

Step 1

Check if Gear is set to max (such as 6 or 7).

Step 2

If gear is set close to Max (such as 6 or 7) and
compressor is always running, turn knob slowly to warmer gear until the compressor stops.

DIAGNOSIS 1

DIAGNOSIS 2

Note
Check for stable status after gear adjustment.


CHECK AND TEST 2
