10.11 Evaporator fan motor
Note: The fan motor is press-fit to the fan.
Replace it as the assembly of the fan.
10.12 Multi-function valve
The multi-function valve features the following.
(1) At the abnormally high pressure, the suction
pressure is controlled to allow the unit to operate
without any abnormal stop (high-pressure cutting).
(2) Since the main valve of the multi-function valve is
closed when the unit is stopped, the liquid does not
return. This eliminates a danger of liquid
compression to improve the reliability of the
compressor.
(3) The pressure equalizing hole of the multi-function
valve makes the pressure difference early balanced
soon after the unit is stopped. This will reduce the
starting torque.
Note: (1) Since the multi-function valve was factory-
set at shipment, don't adjust it at the site.
If the adjusting screw is turned, the setting will
become disturbed to cause a poor operation.
(2) When installing the multi-function valve
and connecting the pipe, don't apply any
shock to the multi-function valve.
Otherwise, it will cause gas leakage or
improper operation.
10.13 Expansion valve
The valve detects overheat at the outlet of the
evaporator so that proper amount of refrigerant can
flow into the evaporator, and make an automatic
adjustment.
When adjusting, turn the adjusting screw at a revolution
of 1/4 and then 1/2 little by little, and see how much
heated it is.
