17. Handling of the Unit
During installing or moving the unit, other substances except refrigerant cannot get into the refrigerant pipe and
there shall not be air remained in the pipe.
If air or other substance gets into the pipe, system pressure will increase and compressor will be damaged.
Do not charge refrigerant of other type into the unit during installing or moving. Otherwise, it may cause poor
operation, malfunction, mechanical failure, or even serious safety accident.
If the refrigerant shall be recycled during moving or maintaining, pressure meter must be used. Set the unit in
cooling mode and close the valve at high pressure side (liquid valve) completely. When the reading of pressure
meter ranges 0~0.05MPa (about 30s~40s), close the valve at high pressure side (gas valve) completely, turn off
the unit and cut off power supply.
If refrigerant recycle time is too long, air may get into the system. In this case, system pressure will increase and
compressor will be damaged.
During recycling refrigerant, make sure the liquid valve and gas valve are closed completely, and the power
supply is cut off before disassembling the connection pipe.
If connection pipe is disassembled when the compressor is still operating, air may get into the system. In this
case, system pressure will increase and compressor will be damaged.
During installing the unit, make sure the connection pipe is connected properly before starting the compressor.
If the compressor is started before finishing connection of connection and when the cut-off valve is opened, air
may get into the system. In this case, system pressure will increase and compressor will be damaged.
The indoor unit and outdoor unit shall be connected properly with required wire. The wiring terminal shall be
secured properly without affecting by exterior force directly.
If the wire is not connected properly or the wiring terminal is not secured properly, fire hazard may be caused.
The wire cannot be refit or reconnected in the middle.
When the length of connection wire is not sufficient, please contact the appointed after-sales service center to
purchase a specialized wire with sufficient length.
18. Installation of Insulated Water Tank
18.1 Installation measure
The insulated water tank should be installed and keep levelly within 5m and vertically within 3m from the indoor
unit. It can be installed in the room.
Standing water tank must be installed vertically with the bottom on the ground, never suspended. Installation
place must be firm enough and the water tank should be fixed on the wall with bolts to avoid vibration, as shown in
the following figure. Weight capacity of water tank during installation should also be considered.
The minimum clearance from the water tank to combustible surface must be 500mm.
