Recharge refrigerant
When the outdoor valve is shut,fill the refrigerant from the access hole at the gas and liquid sides.
If the required filling is impossible,open all the gas and liquid valves,then slightly shut the gas
the compressor and fill the refrigerant from the access hole at the gas side.Now adjust
the refrigerant flow,which will be gasified during absorption by the system.
If there is insufficient refrigerant in the system caused by leaks,refill it after the remaining refrigerant is recollected.
Open all valves
Open all the valves of the outdoor unit.
Heat isolation of the pipes
Separate isolation should be made for the liquid and gas pipes.
Materials used for the pipe isolation at the gas side must withstand above 120 C temperature.
The quantity of the refrigerant t be refilled on the site=Actual length of liquid tube x quantity of
refrigerant to be refilled for per meter of liquid pipe.
valve, run
the gas valve to control
Note:
All the wires should be copper core wires.
The power cable of indoor unit should be equipped according to the operation manual indoor unit.
When connecting the indoor & outdoor wire, check the number of the indoor & outdoor terminals,
with the same number connected together with one wire.
Incorrect wiring will damage the controller of the air conditioner or make the unit work abnormally.
The air conditioner must use special power circuit and special air switch (40A), groundign wire.
The wiring work should be done by a qualified electrician according to the national wiring rule.
The creepage breaker must be installed. The grounding line and the neutral line of the receptacle
separated. It is incorrect to connect the neutral line with the grounding line.
The connection type of power cord is Y connection. If the soft power cord is damaged, to avoid
replaced by the manufacturer or their specific repair department or similar professional worker.
(Sketch map)
1. Power supply
Air conditioner must use an exclusive line (over 30A)
When installation air conditioner in a wet place, try to use a circuit breaker against
Current leakage.
For installation in other places, use circuit breaker as far as possible.
The parameter of power cord is over 2.5mm .
Note: The terminal blocks mark at the two ends of the connection wire should be corresponding one by one,
otherwise the air conditioner cannot work normally.
Electric wiring
Connect wire between indoor & outdoor unit
As the wiring diagram show to arrange the connection wire.
2.The wiring method of straight terminal
For those
connection wires whose end are not orbicular terminals,
their wiring method is: Loosen the connecting screw,
insert the end of the wire directly into the terminal block,
and then tighten screw. Pull the wire outwards slightly to
confirm it is held tightly.
3.Pressing method of connection wire:
After wiring, the connection wire must be pressed with wire holding clamp. The wire holding clamp should press on the
out cover of the connection wire.

1.The wiring method of orbicular terminal
For the connection wire which end is orbicularterminal,
its wiring method is as the right figure shown.
Dismantle the screw and put it through the ring at
the end of the connection wire, then connect it to
the terminal block and tighten the screw.
