SUPRA OPERATOR’S MANUAL
This guide has been prepared for the operator of Carrier Transicold
diesel truck refrigeration units. It contains basic instructions for the
daily operation of the refrigeration unit as well as safety information,
troubleshooting tips, and other information that will help you to deliver the load in the best possible condition. Please take the time to
read the information contained in this booklet and refer to it whenever you have a question about the operation of your Carrier Transicold Supra unit.
Your refrigeration unit has been engineered to provide long,
trouble-free performance when it is properly operated and maintained. The checks outlined in this guide will help to minimize overthe-road problems. In addition, a comprehensive maintenance program will help to insure that the unit continues to operate reliably.
Such a maintenance program will also help to control operating
costs, increase the unit’s working life, and improve performance.
This guide is intended as an introduction to your unit and to provide
general assistance when needed. More comprehensive information can be found in the Operation and Service Manual for your unit.
This manual can be obtained from your local Carrier Transicold
dealer.
When having your unit serviced, be sure to specify genuine Carrier
Transicold replacement parts for the highest quality and best reliability.
At Carrier Transicold, we are continually working to improve the
products that we build for our customers. As a result, unit specifications may change without notice.

UNIT IDENTIFICATION
Each Supra 50 Series unit is identified by a nameplate attached to
the frame near the accumulator. This nameplate identifies the
complete model number of the unit, the serial number, the
refrigerant charge and quantity, and the date the unit was placed
in service.
If a problem occurs, please refer to the information on this plate,
and make a note of the model and serial number before calling for
assistance. This information will be needed when you contact a
technician or Carrier Transicold Service Engineer so that he or she
may properly assist you.
NAMEPLATE

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 guarded 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 all moving parts when the unit is in operation and when the
unit main power switch is in the RUN position.
AUTO-START/STOP
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 the
belts, checking the oil), make certain that the main power switch is
in the OFF position.
ENGINE COOLANT
The engine 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 spray.
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, we recommend that whenever your unit requires service
of the refrigeration system, you contact your nearest Carrier
Transicold authorized repair facility for service.
BATTERY
This unit utilizes a lead-acid type battery. The battery normally
vents small amounts of flammable hydrogen gas. Do not smoke
when checking the battery. A battery explosion can cause serious
physical harm and/or blindness.

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 switch in the STOP (0) 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 (if so equipped). 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 13mm (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.
3. 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 no--maintenance
batteries. These should be inspected to ensure that the
connections are clean and tight, and the battery hold--down
should be checked for tightness.
4
5. Engine Oil -- the engine oil should
be checked last since it is
necessary for oil to drain from the
block and into the oil pan to obtain
a correct reading. Remove the
dipstick, wipe it off 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.
MARKS ONLY
NO WORDING
6. Over-all Unit -- 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 shifting.
7. 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 for damage; check
for damage to 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
across the truck body.

place unit in Start/Stop mode. AUTO
START/STOP will then be illuminated.
The AUTO START/STOP key is used to change the operating
mode from “Continuous Run” to “Auto Start/Stop.” Each push of the
key will alternate the operating modes. The Auto Start/Stop
indicator on the display will illuminate when Auto Stop/Start is
enabled. If the indicator is not illuminated, the unit is in the
Continuous Run Mode.
Automatic start/stop is provided to permit starting/restarting of the
diesel-driven compressor as required. This gives the
microprocessor automatic control of starting and stopping the
diesel engine. The main function of automatic start-stop is to turn
off the refrigeration system near the setpoint to provide a fuel
efficient temperature control system and then restart the engine
when needed. Start-Stop operation is normally used for frozen
loads. Refer to RECOMMENDED TRANSPORT TEMPERATURES (See Page
26).
12
Whenever the unit starts in Auto Start--Stop, it will run until:
SIt has run for the predetermined minimum run time.
SThe engine coolant temperature is above 122°F (50°C)
SThe box temperature is at setpoint.
The controller will not shut off the engine if the battery voltage is not
sufficient to restart it. Battery voltage above approximately 13.4
volts is required for shutdown. This varies depending on ambient.
Look at battery voltage in data list to find out whether shutdown
voltage has been reached. If there is a “+” in front of the number,
the voltage is enough to shutdown and restart. If only the number
appears, the voltage is still too low for shutdown.
The controller will restart the engine if any of the following criteria
have been met:
SBox temperature has changed by ¦ 11°F (¦ 6.1°C)for setpoints
in the perishable range and +11° F (+6.1°C) for setpoints in the
frozen range DURING minimum off time.
SBox temperature has moved away from setpoint by ¦3.6°F
(2.0°C) AFTER minimum off time for setpoints in the perishable
range or +0.5°F (0.3°C) for setpoints in the frozen range.
SThe battery voltage drops below 12.2 Vdc Refer to Page 19 for
unit data).
SThe engine coolant temperature drops below 34°F (1°C).
To start the unit in manual start mode, the unit must be in continuous
run mode and the Auto/Manual Start Operation function parameter
set to “MAN OP” (FN10 OFF)
NOTE
When configuration CNF11 is “ON” and setpoint is 32 to
42_ F (0 to 5.5_C) the unit is locked into continuous run.
The AUTO START/STOP key is disabled.
NOTE
Auto Start-Stop operation may be tied to the setpoint ranges for

PRODUCT LOADING
BEFORE LOADING:
D Pre-cool the body. This will remove much of the heat from the
inside of the body, and give the product better protection when
it is loaded.
D Place the unit in a defrost cycle immediately before loading. This
will remove moisture accumulated on the evaporator coil.
DURING LOADING:
D Turn the unit off!
D Check product temperature during loading.
D Ensure that the air return and supply opening remain
unobstructed.
D Leave approximately 4 to 5 inches between the load and the front
wall for air return to the unit.
D Leave at least 10 to 12 inches between the top of the load and
the ceiling to ensure that there is nothing to prevent airflow to
the rear of the body
D Load product on pallets to provide free air return to unit and
improve product protection.
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 that passes 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. This will
cut off the airflow.
24
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 side-walls of the body, to allow air 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 warm product.
25
RECOMMENDED TRANSPORT TEMPERATURES
Below are some general recommendations on product transport
temperatures and operating modes for the unit. These are included
for reference only and should not be considered preemptive of the
set point required by the shipper or receiver.

must comply with the American Petroleum Institute’s (API) SG/CD
rating. The use of any oil that does not meet this rating may affect
the warranty on the engine in the unit. The use of oil of the proper
weight (viscosity) is also essential. The following chart indicates the
SAE Weight Rating of the oil to be used in various climates:
_F
30W or
15W40
20W or 15W40
10W or 10W30
_C
The following oils are approved for use in the Supra range of units:
In the US, Canada Mexico, Central and South America, any oil that
meets the above API specification is suitable for use in the Supra
range of units. Mobil Delvac1 is the only approved synthetic oil.

STANDBY OPERATION GUIDELINES
For safe, reliable operation in Standby mode, it is important to
follow a few guidelines:
D
Never plug the unit in to the power source with the main switch
in the RUN (I) position. The main switch should always be in the
STOP(O) position when connecting the unit to the power
source.
D
The circuit breaker and extension cable used for Standby
operation should conform to the following:
D
Operating Voltage
FLA
Rating
Circuit
Breaker
Capacity
Cable
Requirement
208/230 V
60 hz
3 phase
15.8 A
50 A
8/3 with ground
(up to 50 ft)
460 V 60 hz
3 phase
13.2 A
30 A
10/3 with ground
(up to 75 ft)
When multiple units are in use, each unit must be operated
on its own electrical circuit. You should never operate more
than one unit on a circuit breaker.
Important note: This information is provided as a guideline only.
When preparing a circuit for operation of the refrigeration unit, a
licensed electrician should be contracted. A licensed electrician is
familiar with all local ordinances and special requirements for your
area and can ensure that the circuits are properly designed and
installed, and that connections are correct.
