Caution for safety installation
Before installing the refrigeration unit, read first this installation manual and follow strictly the instructions to
prevent any trouble or accident.
WARNING
1. Preparations for the vehicle
(1) Use stoppers for front and rear wheels to prevent the vehicle from forward and backward movement during
installation. Furthermore, the parking brake must be activated. If failed to do so. Accidents may occur causing
injuries to worker or operator due to mis-operation.
(2) Turn-off vehicle ignition switch and disconnect negative terminal from the battery. Neglecting to do so would
damage or burn the electrical equipments and may cause accidents like electric shock, short circuit, etc. To
happen if battery terminal comes in contact with the vehicle body, tools or worker.
(3) Before installation, remove the ignition key and keep into a safer place. Then, display a warning sign like that of
"WARNING! work in progress. Don't start the engine". Otherwise, when another worker not knowing the works
starts the engine, and accident may happen.

considered on the weight when handling each main component to avoid back injuries. To be safe, multiple
workers are required.
(2) Be careful of dangerous parts such as high temperature parts or sharp edges of the vehicle and of the
refrigeration unit to avoid from getting burn or other injuries. To be safe, use helmet, gloves and protecting
cover.
(3) When installing, use the right tools, apply the specified tightening torque indicated in this manual and observe
proper posture. To be safe, multiple workers are required.
(4) Mounting places of each component on the chassis must be properly checked for strength and rigidity.
Accidents such as breakage or shearing may occur in case of faulty welding, inappropriate thickness of plate,
etc.
(5) Clearance between moving or rotating parts such as engine, compressor, belt, fan, etc. Must be kept at 15 mm or
more without interference.
(6) Refrigerant circuit pipes and harness must be installed without contact with high temperature parts or edges. If
inevitable, provide protection or insulation.
(7) Earth must be secured properly to prevent short circuit.
Never work with the harness when the hands are wet with oil or water to avoid electric shock.
(8) When charging or discharging refrigerant gas. Extinguish lit cigar or any other fire to prevent production of
