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 38 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 39 and 40.
(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 31 for defrosting timer setting.
2) Manual defrosting operation
Defrosting starts forcibly by pressing the switch of controller.
Refer to page 47 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 46 for how to operate.

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.
• He or she might be frozen to death if
the refrigeration unit is operated with
someone inside.

WARNING
CAUTION
Do not insert sticks or fingers into cold air outlet or inlet.
• Otherwise, it may cause damage of the equipment or injury due to a
fan.
Do not climb up, hang down or put your leg onto the
refrigeration unit.
• Otherwise, it may cause damage of the equipment or injury.
Use the refrigeration unit as the equipment for transport
refrigeration.
• Otherwise, it may deteriorate quality of the cargo if it is used for
any other purpose.
Use specified fuel, engine oil, compressor oil and cooling
water. ( Refer to page 68.)
• Otherwise, it may cause troubles if any other materials are used.
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.
Be sure to carry out the periodic
inspections.
• Otherwise, it may cause troubles of the refrigeration
unit or accidents.

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.
