INTRODUCTION
3. They are stocked with genuine Thermo King
replacement parts.
4. The warranty on your new unit is valid when
the repair and/or replacement of component
parts is performed by an Authorised
Thermo
King dealer.
Performing pre-trip checks on a regular basis will
minimise “on the road” operating problems. A
closely followed maintenance program will also
help keep your unit in
top operating condition.
If
factory recommended procedures are followed,
you will learn that you have purchased the most
efficient and dependable temperature
control
system available.
GENERAL OPERATION
In truck-driven units, temperature control is based
on two values: The setting (Setpoint) of the
electronic thermostat and the evaporator return
temperature. The difference between these two
temperatures will determine the mode of
operation: cool, heat, or null.
• Cool: When the temperature in the load
compartment is higher than the setpoint, the
unit runs in cool mode to reduce the evaporator
return temperature.
• Heat: When the temperature in the load
compartment is lower than the setpoint, the unit
changes to heat mode to raise the evaporator
return temperature.
• Null: Once the Setpoint Temperature has been
reached, and while the temperature remains
between XºC/F above or below the setpoint,
there is no demand for transfer of heat or cold,
and the unit runs in null mode.
• Defrost: After a scheduled period of time in
cool mode, between 30 minutes and 8 hours,
the unit runs in this fourth mode of operation to
eliminate ice that has accumulated in the
evaporator or condenser coil. Defrost can be
initiated automatically or manually.
Factory setting for X is 3ºC (5ºF). During unit
installation, this value can be adjusted in
increments of 1ºC/F.
Units with R-134a refrigerant without defrost:
Temperatures can be controlled from 0ºC to
+22ºC (+32ºF to +71ºF).
Units with R-134a refrigerant with defrost:
Temperatures can be controlled from -10ºC to
+22ºC (+14ºF to +71ºF).
Units with R-404A refrigerant: Temperatures
can
be controlled from -32ºC to +22ºC
(-26ºF to +71ºF).
