Installation Manual

NOTE:

All interconnecting wiring between indoor and outdoor unit must be performed by a a licenced electrical contractor

The electric wiring must be correctly connected.Improper connection may cause spare parts malfunction.

Tighten the terminal screws adequately to prevent loosening.

After tightening the screws, slightly pull the wire and confirm whether it is firm or not.

Ensure the electrical connections are properly earthed to prevent electrical shocks.

Ensure all wiring connections are secure and the cover plates are reinstalled properly.Poor installations that allow dust or moisture incursion may cause fire or electrocution.

Installing Indoor Unit

The piping can be output from right, right rear, left or left rear.

When routing the piping and wiring from the left or right side of indoor unit, cut off the tailings from the chassis as necessary(As shown in Fig.7)

Cut off the tailings 1 when routing the wiring only;

Cut off the tailings 1 and tailings 2 when routing both the wiring and piping.

Take out the piping from body case, wrap the piping, power cords, drain hose with the tape and make them through the piping hole. (As shown in Fig.8)

Hang the mounting slots of the indoor unit on the upper hooks of the mounting plate and check if it is firm enough.(As shown in Fig.9)

The height of the installed location should be 6ft8ft or more from the floor.

Installing Connection Pipe

Align the center of the piping flare with the relevant valve.

Screw in the flare nut by hand and then tighten the nut with spanner and torque wrench referring to the following:

Hex nut diameter Tightening torque (lb ft)

11 ~ 14.7

22.8 ~ 25.8

36.9 ~ 40.6

44.3 ~ 47.9

51.6 ~ 55.3

NOTE: Firstly connect the connection pipe to indoor unit, then to outdoor unit; pay attention to the piping bending, do not damage the connection pipe; ensure the joint nut is adequately tightened, otherwise it may cause leakage.
