Install indoor unit
NOTE:
Where the electric cable length is not long enough, replace with another that is long
enough as joints on the cables are not to be avoided. Ensure the replacement cable
is of the same quality and diameter.
●
The electric wiring must be correctly connected, wrong connection may cause spare
parts malfunction.
●
Tighten the terminal screw.
●
After tightening the screw, slight pull the wire to confirm it is firm.
●
Wrong connection of earth wire may cause electric shock.
●
The cover plate must be reinstalled, otherwise shock, dust and moisture may cause fire,
electric shock or unit malfunction.
Install the indoor unit

The piping can be lead out from right, right rear,
left left rear.
1.
When routing the piping and wiring from the left or
right side of indoor unit, cut off the tailings from
the chassis necessary(Show in Fig.7)
⑴
Cut off the tailings 1 when routing the wiring only;
⑵
Cut off the tailings 1 and tailings 2 when routing
both the wiring and piping.
2.
Gently route the piping from the body case, wrap
the piping, electric wire, water pipe with tape and
pull them through the piping hole (As show in
Fig.8)
