OPERATING INSTRUCTIONS
Note: Each Hour counter will be displayed in
hours when the counted value is <1000.
When the value will be >= 1000, the hours
number will be displayed alternatively between
hours and thousands, into “toh” or “coh”
folders.
For instance, if the counted value is 12055,
“055” will be displayed alternatively with “12”,
where the number with 3 digits is always the
number of “hours”, the number with 2 digits is
always the number of “thousand of hours”.
POST-START INSPECTION
Thermostat.
Adjust the thermostat setting to
above and below the compartment temperature
to check thermostat operation (see Operating
Modes).
Pre-cooling.
With the thermostat set at the desired
temperature, run the unit for half-an-hour to one
hour (or longer if possible) before loading the
truck. Pre-cooling eliminates residual heat and
acts as a good test of the refrigeration system.
Defrost.
When the unit has finished pre-cooling
the truck interior - the evaporator temperature
should have dropped below 2ºC (35.6ºF) - initiate
a defrost cycle with the manual defrost switch.
The defrost cycle should stop automatically.
LOADING PROCEDURE
1. To minimise frost accumulation in the
evaporator coil and a heat increase inside the
load compartment, ensure that the unit is OFF
before opening the doors. (The unit may
continue to run when the truck is being loaded
in a warehouse with the doors closed.)
2. Carefully check and record the load
temperature when loading the truck. Note
whether any products are out of temperature
range.
3. Load the product in such a way that there is
sufficient space for the air to circulate
throughout the load. DO NOT block the
evaporator inlet or outlet.
4. Product should be pre-cooled before loading.
Thermo King units are designed to maintain the
load at the temperature at which it is loaded.
Transport refrigeration units are not designed to
reduce the load temperature.
PROCEDURE AFTER LOADING
1. Ensure that all doors are closed and locked.
2. Adjust the thermostat to the desired
temperature setpoint.
3. Start the unit.
4. Half an hour after loading the truck, defrost the
unit for a moment by pressing the Manual
Defrost switch. If the coil temperature drops to
below 2ºC (35.6ºF), the unit will defrost. The
defrost cycle should stop automatically.
WEEKLY PRE-TRIP CHECKS
1. Visually inspect belt.
2. Listen for unusual noises, vibrations, etc.
3. Visually inspect unit for fluid leaks (coolant,
oil, refrigerant).
4. Visually inspect unit for damaged, loose or
broken parts (including air ducts and
bulkheads, if so equipped).
5. In the event of excess of dirt or obstruction
clean the unit, including condenser and
evaporator coils.
WEEKLY POST-TRIP CHECKS
1. Clean the outside cover of the unit. Use a damp
cloth and neutral detergents. Do not use harsh
cleaning products or solvents.
CAUTION!
Do not use pressurised water.
2. Check for leaks.
3. Check for loose or missing hardware.
4. Check for physical damage to the unit.
