When connecting the cable before installing the indoor unit
Cutting and Flaring Work of Piping
Power Source Installation
1.Insert from outside the room cable into left side of the wall hole,
in which the pipe has already existed.
2.Pull out the cable on the front side, and connect the cable
making a loop.
●Please install the drain hose so as to be downward slope without
fail.
●Please don’t do the drainage as shown below
●Insert the cable from the back side of the unit, then pull it out on
the front side.
●Loosen the screws and insert the cable ends fully into terminal
block, then tighten the screws.
●Pull the cable slightly to make sure the cables have been properly
inserted and tightened.
●After the cable connection, never fail to fasten the connected
cable with the wiring cover
Note:
When connecting the cable, conrm the terminal number of indoor
and outdoor units carefully. If wiring is not correct, proper operation
cannot be carried out and will cause defect.
Connecting wiring 4G1.0mm²
1.If the supply cord is damaged, it must be replaced by the
manufacturer or its service agent or a similar qualied person. The
type of connecting wire is H07RN-F.
2.If the fuse on PC board is broken please change it with the type
of T.3.15A/250VAC (Indoor).
3.The wiring method should be in line with the local wiring
standard.
4.After installation, the power plug should be easily reached.
5.A breaker should be incorporated into xed wiring. The breaker
should be all-pole switch and the distance between its two contacts
should be not less than 3mm.
●Please kindly explain to our customers how to operate through
the instruction manual.
□
Put check mark
in boxes.
●Please pour water in the drain pan of the indoor unit, and conrm
that drainage is carried out surely to outdoor.
●In case that the attached drain hose is in a room, please apply
heat insulation to it without fail.
●The power source must be exclusively used for air conditioner.
●In the case of installing an air conditioner in a moist place, please
install an earth leakage breaker.
●For installation in other places, use a circuit breaker as far as
possible.
●Pipe cutting is carried out with a pipe cutter and burs must be
removed.
● After inserting the are nut, aring work is carried out.
