SAFETY
Your Carrier Transicold refrigeration unit has been designed with
the safety of the operator in mind. During all pre-trip inspections,
daily inspections, and problem troubleshooting, you may be
exposedtomovingparts; pleasestayclear of allmoving partswhen
the unit isin operation and when the Start/Run-Off Switch is in the
START/RUN position.
AUTO-START
YourrefrigerationunitisequippedwithAuto-Startin both Start/Stop
and Continuous Run modes. The unit may start at any time, a
buzzer will sound for 5 seconds before the unit is started. When
performing any check of the refrigeration unit (e.g., checking the
belts, checking the oil), makecertain that the Start/Run-Off Switch
is in the OFF position.
ENGINE COOLANT
The engine is equipped with a pressurized cooling system. Under
normal operating conditions, the coolant in theengine andradiator
isunder high pressureandis veryhot. Contact withhot coolantcan
cause severe burns. Do not remove the cap from a hot radiator; if
the cap must be removed, do sovery slowly in order to releasethe
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 is equipped with 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.

1. Press the AUTO S/S-CONTINUOUS
toggle key until START-STOP is
displayed. Unit is now in Automatic
Start/Stop mode.
START/STOP
Automatic start/stop is provided to permit starting/restartingof 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 toR
ECOMMENDED TRANSPORTTEMPERATURES (SeePage
32).
13
62--10601
The unit will remain in low speed after engine start-up - 5 minutes
for XT products, 10 minutes for all others. If the unit fails to start,
shuts down on a safety, or fails to run for the minimum run time,
three consecutive times, the fault light is on.
Low speed Start--up for low coolant temperatures is available on
Configuration7 for allunits except thosewithEEPROM REV3.23
and 3.24 -- Refer to Page 21 for unit data.
The microprocessor controller monitors box temperature, battery
voltage, and engine coolant temperature.
Whenever the unit starts in 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.
Thecontrollerwillnot shut offtheengineif thebatteryvoltage isnot
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 +1 1° 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 11 Vdc (12.2 Vdc for units with
EEPROM Rev 3.25 and higher -- Refer to Page 21 for unit data).
SThe engine coolant temperature drops below 34°F(1°C).

PRE-TRIP INSPECTION
The pre-trip inspection should be performed before picking up any
load.Thisinspectionisessentialtoanticipateandhelpminimizethe
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
refrigerationunitfuel tankbyopeningthedrain-cock locatedon
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.
Refuelif necessary.Disposeof fuelproperly.Don’t drainwaste
fuel onto ground.
3. Belts -Check thebelt tensionby depressingthe beltwith your
thumb, near the center of the longest free run of each belt.
Under moderate pressure each belt should deflect
approximately 1/4 inchto 1/2 inch(5 mm to 15mm). If thebelts
deflectmorethanthis theyshouldbe tightened(loosebeltsmay
slip, generating heat andreducing belt life). If the belts are too
tight they should be loosened; tight belts can reduce bearing
life.
4. Battery - on unit equipped with serviceable batteries, the level
of the electrolyte in each of the cells should bechecked. If the
level is low ,distilled watershould beadded tothe correctlevel.
Most units,however,areequipped withlowor 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.
5. Engine Oil - the engine oil should be checked last since it is
necessary for oil to drain out of the block andinto the oil panto
obtain a correct reading. Unscrew and remove the dipstick.
Wipe the dipstick clean and insert it into the oil fill tube without
threading it alltheway back intothe tube. Remove thedipstick
again and check oil level. DO NOT add oil if the level is in the
“safe” range. If needed, add oil as indicated by markings on
dipstick until level is in the “safe” range. (See page 35).
29
62--10601
6. Over-all Unit - visually inspect the entire unit for leaks, loose
bolts, frayed, loose, or broken wires, etc. The
radiator/condenser coils of theunit shouldbe freeof dirt,bugs,
cardboard, orany otherdebristhat mayobstruct airflow across
the coils. The evaporator (located inside the trailer) should be
free of debrisalso,especially stretch-wrap, whichis oftenused
during transport to prevent cargo shifting.
7. Start a Pretrip Check (See Page 8). The unit will cycle thru all
modesofoperationat30secondintervals, andreturntonormal
operation when complete. Monitor Pretrip and watch/listen for
unusual operation or noises.

62--10601
PRODUCT LOADING
BEFORE LOADING:
D Pre-cool the trailer. This will remove much of the heat from the
inside of the trailer,and givethe product better protection when
it is loaded.
D If possible, placethe 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 (10 to 12 cm) between the
load and the front wall for air return to the unit.
D Leave at least 10to 12 inches (25 to 30 cm) between the top of
theload and theceilingto ensure thatthereisnothingtoprevent
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 trailer, air that can move around and
through theload, isa critical elementin maintainingproduct quality
during transport. If aircannot circulate completely aroundthe 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 usingpallets, it isimportant to refrain from stacking extra boxes
on the floor at the rear of the trailer, this will cut off the airflow.

62--10601
Product stacking is another important factor in protecting the
product. Products that generate heat - fruits and vegetables, for
example-should bestackedsotheaircanflowthrough theproduct
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
shouldbekept away fromtheside-wallsof the body,toallowairflow
between the body and the load; this preventsheat filteringthrough
the walls from affecting the product.
It is importantto checkthetemperatureof theproduct 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.

UNIT MAINTENANCE 3.
Engine oil - the oils recommended for use inyour refrigeration unit
must comply with the American Petroleum Institute’s (API) CI or
higher rating or Mobil Delvac 1synthetic oil. The use ofany oilthat
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:

T o check the engine oil level: Run the
unit to bring the engine up to operating
temperature, shut the unit off, and
unscrew the cap/dipstick. Wipe the
dipstick clean and insert it into the oil fill
tube without
threading it all the way back
into the tube. Remove the dipstick again
and check oil level. DO NOT add oil if the
level is in the “safe” range. If needed, add
oil as indicated by markings on dipstick
until level is in the “safe” range.
