2.Connection of pipes
To bend a pipe, give the roundness as large as possible not to crush the pipe ,and the bending radius
should be 30 to 40 mm or longer.
Connecting the pipe of gas side first makes working easier.
The connection pipe is specialized for R410A.
The max vertical distance between the indoor unit and the outdoor unit is 5 m.
Half union
Spanner
Torque wrench
Be careful that matters, such as wastes of sands, etc. shall not enter the pipe.
The standard pipe length is 5m. If it is over 5m, the function of the unit will be affected. If the pipe has
to be lengthened, the refrigerant should be charged, according to 20 g/m. But the charge of refrigerant
must be conducted by professional air conditioner engineer. Before adding additional refrigerant,
perform air purging from the refrigerant pipes and indoor unit using a vacuum pump,then charge
additional refrigerant.
3.Connection
Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into
terminal block, then tighten the screws.
Insert the cable according to terminal number in the same manner as the indoor unit.
If wiring is not correct, proper operation can not be carried out and controller may be damaged.
Fix the cable with a clamp.
