1. Items to Observe (Safety Precautions)
• The meanings of the "signs" used in this manual are as follows.
WARNING
CAUTION
Precautions for installation
Please read this section "Items to Observe (Safety Precautions)" before using, to ensure that the
unit is used correctly.
The precautions given here describe important information related safety, and must always be observed.
• The signs and meanings are as follow.
Never perform.
Always ground.
Never touch.
Things you should know.
ADVICE
If mishandled, may result to serious injuries or fatalities.
If mishandled, serious results could occur depending on
the situation.
Always carry out according to the
instructions.
Always disconnect power supply
plug from socket.
Repairs and disassembly must be
done by qualified personnel.
• Store the operation manual in a place that is easy to access for future reference after reading it.
• If the ownership of the product is transferred, or if the product is lent out, always hand this oper-
ation manual to the new user so that the safe and correct usage methods can be understood.
DANGER
Indicates high and imminent potentially dangerous
situation, which if mis-handle, will result in death, injury, or
serious accident such as damage of the refrigeration unit.
WARNING
Always ground
Incomplete grounding could lead to electric shocks.
Insufficient electric circuit capacity or incorrect work could lead to electric shocks or fires.
Always use a dedicated circuit and leakage breaker for the electric
work.
DANGER
Cracking occurs in design panel, which cause a risk of falling down of panel while
the vehicle is running.
Do not paint on resinic design panel. (This will make refrigeration
unit out of warranty.)
It may cause a serious accident if customer modify the refrigeration unit or
change the specification by himself/herself.
Do not modify or perform specification change for refrigeration and
vehicle. (This will make refrigeration unit out of warranty.)

Precautions for usage
WARNING
Always stop operation in an
abnormal state.
Continuing operation in an abnormal state
could lead to electric shocks or fires, etc.
Do not place volatile or flammable
matters in the room.
Failure to observe this could lead to
explosions or fires.
Do not wash the unit with a high-
pressure washer or steam washer.
Washing with high-pressure fluids could cause
the condenser fins to damage. Washing with
steam could cause the internal pressure to
rise abnormally and lead to ruptures.
Do not insert fingers, rod, etc., in
the air intake or outlet ports.
Since the fan is rotating at a high speed
inside, it could lead to injuries or troubles.
Do not directly splash water on
the electric parts, or wash them
with water.
It could lead to short circuits or electric
shocks.
Never touch the electric parts such as
the power supply plug with wet hands.
Never operate the switches with wet
hands.
Failure to observe this could lead to electric shocks.

Items to Observe
Do not modify, apply undue force by,
for example, bending forcibly, pulling
hard, twisting, etc., place under a
cargo or pinch the power cord.
It could damage the power cord and
result in fires or electric shocks.
Confirm that there is no dust on
the power supply plug, and that
the plug is not loose before
connecting it securely.
Adherence of dust or incomplete connection
could lead to electric shocks or fires.
Always hold the power supply
plug when disconnecting the
power supply cord.
Pulling on the cord could cause some wires
to break and lead to overheat or fires.
Do not move the vehicle while the
commercial power supply is
connected.
Moving the vehicle while the power supply
is connected could lead to damage of the
devices, electric shocks or fires, etc.
Protect the power supply socket
with the cover when it is not
used. If the cover is damaged,
repair it immediately.
Failure to use the cover or use of damaged
cover could lead to electric shocks or fires.
WARNING
• Use 4-core cabtyre cables (con-
ductor cross section with 5mm2or
more) for power cable. Do not con-
nect it to extension code.
• Use MENNEKES Part no.6 (400V
32A) for power supply plug.
Use of a power supply cord other than a
dedicated cord and plug, a relay or
extension cord could lead to electric
shocks, overheat or fires.

Verify that the digital display
area is blank, or that only the
time is displayed.
Items to Observe
Use the transportation device as
intended.
Use of this device for other purposes could
deteriorate the quality of cargo or other troubles.
Do not start and stop operation by connecting
and disconnecting the power supply breaker or
power supply plug.
Failure to observe this could lead to faults
in the electrical circuit or to electric shocks.
Periodically confirm the operation of the
leakage breaker.
Use of the leakage breaker in a fault state
could impair operation in the event of a current
leakage or could lead to electric shocks.
Always press the [RUN/STOP] switch and disconnect
the power supply plug before starting cleaning,
maintenance or inspection. (Turn OFF the power
supply circuit.)
Failure to observe this could lead to
electric shocks or injuries from the fan.
CAUTION
WARNING
Do not use the cabin controller when driving the vehicle.
It could cause trouble.
Do not leave combustible objects around the exaust pipe.
These could catch fire.
It could cause injury or trouble.
Do not use the refrigeration unit in explosive atmosphere.
It could cause explosion, fire, or other accident.
It is prohibited standing on, hanging down from, holding on or
stepping on the refrigeration unit, or other similar acts.
Do not touch the high-temperature sections such as the exhaust pipe
or high pressure pipes during operation of the refrigeration unit.
Doing so could cause burns.
Do not discharge a refrigerant in the atmosphere.
It could cause environmental disruption.

Items to Observe
Precautions for inspections
Persons other than repair technicians or
qualified personnel must never disassemble
or repair the unit.
Incorrect disassembly or repairs could lead to injuries from
abnormal operations or to electric shocks or fires, etc.
Use the rated fuse.
Use of an incorrectly rated fuse (wire or copper
wire) could lead to fires or electric shocks, etc.
WARNING
If a fault occurs, stop the refrigeration unit, contact your nearest dealer, and maintain the
load temperature.
When a fault occurs
Never make modifications.
Making modifications could lead to ruptures, electric shocks, fires or injuries, etc.
Put on protective eyeglasses and groves when handling the refrigerant.
It could lead to injuries.
Do not run the motor at an incorrect voltage.
Doing so could lead to faults in the refrigeration unit or to fires.
Do not touch the rotary section (each pulley, drive belt,
condenser fan sub-engine cooling fan) in the condensing unit.
Doing so could lead to faults in the refrigeration unit.
Do not use brands of refrigerant, refrigerating machine oil, sub-engine
oil, sub-engine fuel, coolant (antifreeze) other than those designated.
Direct contact with the refrigerant could freeze the skin. If it enters in the
eye, it could lead to loss eyesight.
