This refrigeration unit has following functions.
(1) Drive switching function
This is the function to switch the drive (engine/motor) depending on
whether the commercial power supply is connected or not.
Refer to page 35 for how to switch the drive.
(2) Operation pattern selection function
This is the function to switch operation pattern (automatic start/stop
operation/continuous operation).
For the switching of operation pattern, refer to pages 36 and 37.
(3) Defrosting operation function
This is the function to protect evaporator from frosting during cooling
operation and to prevent refrigerating power from decreasing.
There are following 2 methods to start defrosting operation.
1) Automatic defrosting operation
Defrosting starts automatically by the timer setting.
Refer to page 29 for defrosting timer setting.
2) Manual defrosting operation
Defrosting starts forcibly by pressing the switch of controller.
Refer to page 42 for how to operate.
As the defrosting operation is completed, the refrigeration unit returns to
the cooling operation.
Defrosting operation will not start when the evaporator temperature is
high even during the cooling operation
(4) Whisper operation function
This is the function to lower the operation sound with fixing the engine at
slow speed forcibly during engine driving.
Refer to page 41 for how to operate.

The cover prevents operators from contacting with the rotating part
during operation.
(d) Front panel opening detection switch
When the front panel is opened for inspection, for example, this switch
detects it and stops the start of engine or motor.
( Refer to page 54.)
People who handle this refrigeration unit are requested to understand the
functions of these protective devices completely to use it safely. Do not

Precautions
General precautions
DANGER
Do not modify or perform specification change for the
refrigeration and vehicle. (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 paint on resinic design panel. (This will make
refrigeration unit out of warranty.)
• Cracking occurs in design panel, which cause a risk of falling down
of panel while the vehicle is running.
WARNING
Do not place combustible materials
in the vicinity of muffler and exhaust
pipe. Do not park on the area where
combustibles such as falling leaves
accumulate on.
• Otherwise, it may cause a fire because muffler
and exhaust pipe will be hot.
Do not start the engine in poorly
ventilated places such as an indoor
parking lot.
• Otherwise, it may cause carbon monoxide
poisoning due to exhaust gas.
Do not use the refrigeration unit in
the atmosphere which could cause
explosion at such place like
gas station.
• Otherwise, it may cause an
explosion or a fire.
Make sure that no one left inside the
container before closing the door.

During and after the operation
WARNING
Make sure that the front panel
of condensing unit is closed
before starting operation.
• Otherwise, it may cause accidents.
CAUTION
Do not touch the muffler, exhaust pipe and refrigerant pipe
during operation or immediately after the operation.
• Otherwise it may cause burns, as the muffler, exhaust pipe and
refrigerant pipe will get hot.
Do not open the radiator cap during operation or
immediately after the operation.
• High temperature steam may blowout and cause burns.

Inspection/Cleaning/Repair
WARNING
Do not disassemble and repair by
yourself.
• Otherwise, it may cause damages or
an electric shock.
CAUTION
When refrigerant and compressor oil leak out or when you
handle antifreeze coolant or engine oil, be careful not to
have them get in your eyes, not to have them contact with
your skin, not to inhale them or not to drink them by mistake.
• Otherwise, it may cause health disorders such as frostbite, loss of
eyesight and pneumonia.
Do not wash the refrigeration unit with a steam washer or
a high pressure washer.
• Otherwise, it may cause a rupture due to pressure rise in the
refrigeration unit or distortions of the condenser fin.
When inspecting or cleaning the refrigeration unit, stop the
unit by turning the "Main switch" to "OFF" and disconnect
the battery terminals and power supply cord plug.
• Otherwise, it may cause injury or an electric shock due to
unexpected start
.
When inspecting or cleaning the refrigeration unit, apply
the parking brake and put chocks under wheels.
• Otherwise, the vehicle may start to move, causing injury or
accident.

Loading
WARNING
Do not load the volatile or inflammable
cargos in the container.
• Otherwise, it may cause an explosion or a fire.
CAUTION
Cool down or heat up the cargos to the designated
temperature in advance with other refrigerating device.
• If the cargos are not kept in the designated temperature, it
may deteriorate quality of the cargos due to inside container
temperature rise.
Waterproof the cargos if they need to be.
• Water may drip or splash from the evaporator unit.
Handling of electric equipment and power codes
WARNING
• Do not directly splash water on the electric
equipment or wash them with water.
• Never touch the electric equipment
such as power plug and so on or
operate the switches with wet hands.
• Do not modify the power code or apply force
on it, by bending it by force, pulling it strongly
or twisting it, or do not put cargos on it.
• Otherwise, it may cause troubles of electric circuit, damages of
power codes or an electric shock.

part at the end of the code.
• Check the plug of the power code for dust.
If there is no dust, insert it firmly.
• Surely protect the power socket
with a cover when it is not used.
When the cover is damaged, repair
it immediately.
• Otherwise, it may cause an electric shock or a fire
due to the heat, breaking of wire and leaking of
water, etc.
CAUTION
Do not start and stop the operation with pulling out or
inserting the power supply breaker or power code.
• Otherwise, it may cause troubles of electric circuit, damages of
