Inspection and adjustment of belt
1. Remove the screw and remove the belt
cover.
2. Use professional tooling Adjust the belt
tightness.
3. If the belt tightness is not within the
range, loosen 4 bolts first.
Then adjust the belt tightness or change
the belt.

4.Reassembly is the reverse of removal.
NOTE:
If the belt needs to be replaced, please
follow the specified specifications and
models.

avoid scalding.
Compressor electromagnetic clutch
The function of the electromagnetic clutch
is to transmit the power of the engine to
the compressor through the pulley. When
refrigeration, the electromagnetic clutch
coil is electrified to generate magnetic force,
and the clutch armature is closed to drive
the compressor spindle to run. After
cooling, cut off the coil power supply, the
magnetic force disappears, the pulley
rotates over the bearing, and the
compressor stops running.

MULTIMETER
Unplug the connector of electromagnetic
clutch and measure the resistance between
terminal and ground.
Set the multimeter to 20Ω.
TEST probes
Resistance
Terminal and ground
3±0.5Ω
If the resistance is not within the range, the
electromagnetic clutch needs to be
repaired or replaced.
Condenser
The condenser w is the unit that receives
the high pressure, high temperature
refrigerant vapor from the compressor and
condenses it into a high temperature liquid.
Condenser: The condenser is the unit that
