NOTE:
When connecting the electric wire if the wire length is not enough, please contact with
the authorized service shop to buy a exclusive electric wire that is long enough and the
joint on the wire are not allowed.
The electric wiring must be correctly connected, wrong connection may cause spare
parts malfunction.
Tighten the terminal screw in order to prevent loose.
After tighten the screw, slightly pull the wire and confirm whether is it firm or not.
If the earth wire is wrong connection, that may cause electric shock.
The cover plate must be fixed, and tighten the connection wire, if it is poor installed, that
the dust, moisture may enter in or the connection terminal will be affected by outside force,
and will cause fire or elelctric shock.
Install the indoor unit
The piping can be lead out from right, right rear,
left, left rear.
When routing the piping and wiring from the left
or right side of indoor unit, cut off the tailings
from the chassis in necessary (show in Fig.2)
(1).Cut off the tailings 1 when routing the wiring only;
(2).Cut off the tailings 1 and tailings 2 when routing
both the wiring and piping.
(or 1,2,3);
Take out the piping from body case, wrap the piping
electric wire, water pipe with tape and put them th-
