SAFETY
Your Carrier Transicold refrigeration unit has been designed with the
safety of the operator in mind. During normal operation, all moving
parts are fully enclosed to help prevent injury. During all pre--trip
inspections, daily inspections, and problem troubleshooting, you
may be exposed to moving parts; please stay clear of these moving
parts when the unit is in operation and when the main power switch
is in the Run (On) position.
The evaporator and condenser are made of finned tubes. The fins
can cause injury on contact with skin. It is recommended to wear
protective gloves during all handling operations.
During operation, certain components such as the exhaust pipe,
discharge outlet, and cooling circuit radiator can become extremely
hot. During routine service operations, wear protective gloves.
WARNING : When the buzzer sounds the unit will start
30 seconds later.
AUTO START/STOP (OPTION FOR ELECTROMECHANICAL)
Your refrigeration unit is equipped with Auto--Start/Stop, a valuable
fuel--saving feature. When the unit is set for Auto--Start/Stop
operation it may start at any time and without warning. When
performing any check of the refrigeration unit (e.g. checking belt
tension, or the oil level), make sure that the main power switch is in
the Stop position.
To ensure your unit is fitted with the START/STOP system, check
for the presence of switch 16 (see page 25).
ENGINE COOLANT
The engine, as with all diesel engines, is equipped with a
pressurized cooling system. Under normal operating conditions, the
coolant in the engine and radiator is under high pressure and is very
hot. Contact with hot coolant can cause severe burns. Do not
remove the cap from a hot radiator; if the cap must be removed, do
so very slowly in order to release the pressure without spraying.
6
SAFETY
REFRIGERANTS
The refrigerant contained in the refrigeration system of your unit can
cause frostbite, severe burns, or blindness when in direct contact
with the skin or eyes. For this reason, and because of legislation
regarding the handling of refrigerants during system service,
whenever your unit requires service of the refrigeration system, we
recommend that you contact your nearest Carrier Transicold
authorized repair facility for service.
BATTERY
This unit is equipped with a lead--acid type battery. The battery
normally vents small amounts of flammable hydrogen gas. Keep
any flame, any lighted object (cigarette etc.) or any source of sparks
away from the battery elements. A battery explosion can cause
serious physical harm and/or blindness.

FEATURES
- In Road mode (engine operation)
The diesel engine runs continuously. During temperature pulldown
it runs at high speed. Down to --12•C, the box temperature is
regulated is in low--speed heat; under --12•C, a safety cut--out
prevents any possibility of heating: this means that as soon as the
set--point temperature has been reached the unit will run in
low--speed cool.
NOTE: If a fixed negative temperature selection is required lower
than --12•C (e.g. --15•C or --20•C or --25•C), please contact your
local Carrier dealer or service.
- In Standby mode
WITH START / STOP
The thermostat controls unit shut--down as soon as the set--point
temperature has been reached.
WITHOUT START / STOP
The unit will run continuously :
cool / heat for setpoint above --12•C
only cool for setpoint below --12•C
- Defrost
The unit is equipped with an automatic defrost.
Triggering of the defrost cycle is controlled by a differential pressure
air switch; shut--down of the defrost cycle is controlled by two
defrost termination thermostats. The defrost cycle can also be
controlled manually. During the defrost cycle the evaporator blower
is off.

MICROPROCESSOR CONTROLLER
AUTOMATIC START/STOP CONTINUOUS
Switches the operating mode of the unit from
Automatic Start/Stop to continuous operation in
Road or Standby modes. When the unit is set to
Automatic Start/Stop, it operates in this mode until
the box temperature reaches the set-point, then
stops (after operating for the minimum run time).
See page 16 (Function Parameters -- FN3) until a
heating or cooling cycle becomes necessary once
again (after minimum off time -- FN2).
In continuous run mode, the unit automatically
cycles from heating to cooling modes as required to
maintain the box temperature at the set-point. In the
case where the latter is lower than --12•C, the unit
does not heat, but continuously operates in low
speed cooling mode.
When set to continuous run mode, the unit only shuts
off when the Run/Stop switch is moved to the Stop
position, or a unit fault occurs.

PRE-TRIP INSPECTION
The pre--trip inspection should be performed before picking up any
load. This inspection is essential to anticipate and help minimize the
possibility of “over--the--road” problems. These checks take only a
few minutes.
1. Place the unit’s main power switch to the Stop position.
2. Fuel -- Drain any water and impurities from the sump of the refrigeration unit fuel tank by opening the drain--cock located on
the bottom of the tank. Close the valve when only pure fuel
emerges. Check the fuel level in the tank, ensuring that the fuel
supply is adequate for unit operation. Refuel if necessary.
3. Belts -- Check the belt tension by depressing the belt with your
thumb, near the center of the longest free run of each belt.
Under moderate pressure each belt should deflect approximately 6 mm to 13 mm (1/4 inch to 1/2 inch). If the belts deflect
more than this they should be tightened (loose belts may slip,
generating heat and reducing belt life). If the belts are too tight
they should be loosened; tight belts can reduce bearing life.
4. Battery -- On units equipped with serviceable batteries, the
level of the electrolyte in each of the cells should be checked.
If the level is low, distilled water should be added to the correct
level. Most units, however, are equipped with low or maintenance--free batteries; these should be inspected to ensure that
the connections are clean and tight, and the battery hold--down
should be checked for tightness.
18
MICROPROCESSOR CONTROLLER
5. Engine Oil -- The engine oil should be checked last, since oil
has to drain out of the block and into the oil pan to obtain a
correct reading. Remove the dip--stick (1), wipe it clean and
re-insert it fully into the engine block. Once again, remove the
dip--stick and observe the oil level; it should be somewhere
between the ”full” and ”add” marks. If it is below the add mark,
add oil until the level is correct.
G
B
1
6. Coolant level -- Visually inspect the coolant level in the coolant
bottle (located on the upper left-hand side of the unit).
7. Over--all Unit inspection -- Visually inspect the entire unit for
leaks, loose bolts, frayed, loose, or broken wires, etc. The
radiator and condenser coils of the unit should be free of dirt,
bugs, cardboard, or any other debris that may obstruct airflow
across the coils. The evaporator (located inside the body)
should be free of debris also, especially stretch--wrap, which
is often used during transport to prevent cargo from shifting.
8. Truck body -- The body should be inspected prior to loading.
Check the door and vent seals for damage and wear. Inspect
the entire interior and exterior of the body to detect any damage, including the inner and outer skins of the body. Damage to
the insulation may compromise the unit’s ability to maintain the
product temperature by increasing the amount of heat gain in
the box.
9. Pretrip -- Initiate a pretrip by pressing the PRETRIP Key.

UNIT OPERATION
STARTING THE UNIT
Complete the Pre-trip inspection described in the previous section.
Road Operation
Place the RUN/STOP (2) switch to the RUN position. If the unit was
previously operating in STANDBY mode, place the switch to the
ENGINE position (3). Under normal operating circumstances, this
is all that is required to start the unit. The microprocessor initiates
a unit pretrip check, initiates preheating for a period determined by
the temperature of the engine coolant, and automatically starts the
unit.
Standby Operation
Check that the unit is connected to a suitable electricity supply.
Place the RUN/STOP (2) switch to the RUN position, and the
Standby switch to STANDBY (3). The unit now operates on
Standby. See the table on page 52 for information about the
appropriate wiring.
MANUAL START
1. Place the switch (2) to RUN to control the unit.
2. Place the unit preheat and manual start switch to mode [diesel
engine start-up (MGC)] -- see on Control Relay Box page 14.

CHANGING THE SET-POINT
Press the UP ARROW or DOWN ARROW key until the desired
set-point is displayed on the left side of the cab command display
window. When the arrow key is released, the set-point will begin
flashing, this is a sight that you must press the ENTER key to
confirm the new set-point. Otherwise, the set-point will revert to the
previously entered set-point.

DEFROST
- Defrost is fully automatic but can be manually initiated if required,
as long as the box temperature is equal to or lower than +3•C.
- It is recommended to carry out a defrost cycle one hour after
loading, particularly when transporting goods such as fresh meat
etc ...
- The automatic defrost cycle is controlled by an air switch or by a
defrost timer (preset 1,5 -- 3 -- 6 and 12 hours) using hot gas from
the compressor.
- During the defrost cycle, the evaporator fan is stopped.
- Defrost termination is automatically controlled by two “klixon”
thermostats.
- During defrost, the Defrost light is On.

DEFROST
- Defrost is fully automatic but can be manually controlled if
required, as long as the box temperature is equal to or lower than
+3•C.
- It is recommended to carry out a defrost cycle one hour after
loading, particularly when transporting goods such as fresh meat
etc ...
- The automatic defrost cycle is controlled by an air switch using hot
gas from the engine.
- During the defrost cycle, the evaporator fan is stopped.
- Defrost termination is automatically controlled by two “klixon”
thermostats.
- During defrost, the Defrost light is On.
HEATING
In Road mode (Engine operation)
- Heating is controlled by the thermostat.
- Heating takes place in high-and low-speed heat modes.
- Temperature regulation takes places in high-and low-speed heat
modes.
In Standby mode (Electric operation)
- Temperature regulation is obtained by the unit cycling off when the
set-point has been reached.
35
SOLID STATE CONTROLLER
START/STOP SYSTEM
(OPTION FOR ELECTROMECHANICAL) :
The system works as follows :
- Engine preheat and start-up is automatic.
- When the temperature selected with the thermostat has been
reached, the system shuts the diesel engine down.
- Engine shut-downs can be programmed to last 15, 30 or
60 minutes. Shut-down times will be modified depending on the
isothermal insulation of the box, the ambient temperature and the
cargo. The shut-down time is pre-programmed in the plant to
15 minutes. The user should determine whether this setting is
appropriate for his type of cargo and the insulation of the
bodywork (all adjustments are to be made by a Carrier Transicold
technician).
Caution : During unit shut-downs, the evaporator fans also stop.
Only use this operating mode for products which tolerate
shut-downs of this kind.
- At the end of the programmed shut-down time, if the box
temperature is more than 1,7•C outside the set-point range, the
system restarts the engine for a minimum of 10 minutes.
- The start/stop system comprises several safety devices which
ensure it operates correctly. These check :
the battery status,
the temperature of the engine water,
the minimum run time.
36
SOLID STATE CONTROLLER
TEMPERATURE REGULATION
In Road mode (Engine operation)
- Down to --12•C, the box temperature is regulated in low-speed
heat and low-speed cool; under --12•C, a safety cut-out prevents
any possibility of heating: this means that as soon as the set-point
temperature has been reached the unit will operate in low speed
cool.
- The continuous operation of the fans even during temperature
regulation ensures a precise, uniform temperature of the cargo
transported.
In Standby mode
- Temperature regulation is obtained by the unit cycling off when the
set-point has been reached.

PRODUCT LOADING
Proper air circulation in the truck body, air that can move around and
through the load, is a critical element in maintaining product quality
during transport. If air cannot circulate completely around the load,
hot spots or top--freeze can occur.
The use of pallets is highly recommended. Pallets, when loaded so
air can flow freely through the pallets to return to the evaporator,
help protect the product from heat passing through the floor of the
trailer. When using pallets, it is important to refrain from stacking
extra boxes on the floor at the rear of the trailer, because this will cut
off the airflow.
Product stacking is another important factor in protecting the
product. Products that generate heat, fruits and vegetables for
example, should be stacked so the air can flow through the product
to remove the heat; this is called “air stacking” the product. Products
that do not create heat, meats and frozen products, should be
stacked tightly in the center of the trailer. All products should be kept
away from the sidewalls of the body, allowing air to flow between the
body and the load; this prevents heat filtering through the walls from
affecting the product.
It is important to check the temperature of the product being loaded
to ensure that it is at the correct temperature for transport. The
refrigeration unit is designed to maintain the temperature of the
product at the temperature at which it was loaded; it was not
designed to cool a warm product.
OPTIONS FOR INSULATED BODIES
- Mobile partition
The mobile partition must be placed at a minimum distance of
4000 mm from the evaporator.
- Ducting of evaporator air outlet. Ventilation ducts must
never be covered.
48
PRODUCT LOADING
SOME ADVICE
Before loading
- Pre--cool the inside of the insulated body by lowering the
temperature for about 15 minutes.
- Remove the humidity inside the body by defrosting manually. This
can be done only when the inside temperature is 3•C or less.
G
B
When loading
- This is to be carried out with the unit stopped.
- It is recommended to open doors as little as possible to avoid the
intake of hot air and humidity.
- Select the temperature using the thermostat in accordance with
the goods transported.
- Check the internal temperature of the goods being loaded (using
a probe thermometer).
- Take care not to obstruct the air intakes on the evaporator section
and the ventilation ducts.
- Leave a free space of about:
6 to 8 cm between load and frontwall,
20 cm between the top of the load and the roof,
between the floor and the load (gratings, pallets).
- Do not forget to close the rear ventilation flaps.
- Before closing the doors, check your load once more and see that
nobody is shut inside the trailor.
49
PRODUCT LOADING
NOTE
If used stationary, it is recommended to place the box in the shade.
Important :
Never leave your unit too long without operating.
