The piping can be run in the 3 directions as indicated by
numbers in the picture . When the piping is run in
direction 1or3, cut a notch along the groove on the side
of the indoor unit.
Run the piping in the direction of the wall hole and bind
the copper pipes , the drain pipe and the power cables
together with the tape with the drain pipe at the bottom,
so that water can ow freely.
Do not remove the caps from the pipe until ready to connect
, to avoid humidity or dirt from entering.
If the pipe is bent or pulled too often , it will become
weakened . Do not bend the pipe more than three times at
one point.
When extending the rolled pipe, straighten the pipe by
unwinding it gently as shown in the picture.
1. Remove the indoor unit pipe cap (check that there is
no debris inside).
2. Insert the fare nut and create a are at the extreme
end of the connection pipe.
3. Tighten the connections by using two wrenches
working in opposite directions

Indoor unit condensate water drainage
The indoor unit condensed water drainage is essential
for the success of the installation.
1. Place the drain hose below the piping, taking care not
to create siphons or traps.
2. The drain hose must slant downwards to aid drainage.
3. Do not bend the drain hose or leave it protruding or
twisted and do not put the end of it in water . If an
extension is connected to the drain hose , ensure that
it is lagged when it passes into the indoor unit.
4. If the piping is installed to the right, the pipes, power
cable and drain hose must be secured onto
the rear of the unit with a pipe connection.
1) Insert the pipe connection into the appropriate slot.
2) Press to join the pipe connection to the base.
