Unit Description
37
Receiver Tank Sight Glass:
This sight glass indicates the
level of refrigerant in the receiver tank.
Operate the unit in high speed cool for approximately 15
minutes to stabilize operating conditions and temperature
before attempting to check the refrigerant.
NOTE: If the ball floats, there is sufficient refrigerant in the
unit for that load at that particular trailer temperature. This
test does not determine if the unit contains a full charge or an
overcharge of refrigerant.
Unit Protection Devices
Fuse Link (Current Limiter):
The fuse link is located in the
positive battery cable. The fuse link protects the electric
system from a short. If the fuse link burns out, replace it by
replacing the positive battery cable.
High Pressure Cutout Switch:
The high pressure cutout
switch (HPCO) is located on the compressor discharge
manifold. If the compressor discharge pressure becomes
excessive, the switch opens the circuit to the run relay to stop
the unit. The microprocessor will record Alarm Code 10.
High Pressure Relief Valve:
This valve is designed to
relieve excessive pressure in the refrigeration system. It is
located on the receiver tank. If the high pressure relief valve
opens, much of the refrigerant will be lost. Take the unit to a
Thermo King dealer if this occurs.
Low Oil Level Switch:
The low oil level switch closes if the
oil drops below an acceptable level. If it stays closed for a
specified time, the microprocessor shuts the unit down and
records Alarm Code 66.
Low Oil Pressure Switch:
The low oil pressure switch
closes if the oil pressure drops below an acceptable level. If it
stays closed for a specified time, the microprocessor shuts the
unit down and records alarm code 19.
Preheat Buzzer:
The preheat buzzer sounds when the
controller energizes the preheat relay. This warns anyone near
the unit that the controller is about to start the engine.
