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. 4.Attaching Drain-Elbow If the drain-elbow is used, please attach it as figure. (Note: Only for heat pump unit.) 6

Install according to
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.
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 7m, 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.
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.
If wiring is not correct, proper operation can not be carried out and controller may be damaged.
If the drain-elbow is used, please attach it as
