2.4.4 Preparation for connection pipes
It is necessary to make a hole in the wall where the
refrigerant piping, drainage pipe and electrical cables
that will connect the indoor unit to the outdoor unit will
pass through.
1 Determine hole position in the wall according to
the position of the outdoor unit. The hole in the wall
should have a minimum diameter of 65 mm and a
slight downward slope to facilitate drainage (see "Fig.
25").
2 Drill the hole in the wall using a 65 mm drill bit. The
hole should have a slight inclination, so that the outer
end is lower than the inner one by about 12 mm. This
will facilitate water drainage.
Inside
3 Insert the protective sleeve into the wall, which will
protect the edges of the hole and improve the seal
after installation.
CAUTION DANGER
When drilling holes, pay attention to avoid
electrical wires, hydraulic hoses and other
delicate components.
CAUTION
The drain pipe outlet must be at least 5 cm
from the floor. If it touches the ground, the unit
can block and not work properly. If the water is
discharged directly into the sewer system, use
a U- or S-shaped drain pipe to block odours
which would otherwise flow back inside.

2.4.5 Drainage pipe
The drainage pipe is used to drain the water from the
unit. Incorrect installation can cause damage to the unit
and other material damage.
CAUTION DANGER
– Insulate all of the pipes to prevent
condensate from forming, which could
cause water damage.
– If the drainage pipe is bent or not installed
properly, the water can escape and cause
the float switch to malfunction.
– In HEAT mode, the outdoor unit discharges
water. Make sure that the drainage pipe is in
a suitable area to avoid water damage and
slipping hazards caused by the discharge
water freezing.
– DO NOT pull the drainage pipe, as this could
detach it.
WARNING
A polyethylene pipe (outer diameter =
3.7-3.9cm, inner diameter = 3.2cm) is required
for this installation, which you can find in
hardware shops or from your local dealer.
INSTALLATION OF INDOOR DRAINAGE PIPE
1 Install the drainage pipe as shown in the figure:
2 Cover the drainage pipe with a heat-insulating material
to prevent condensate and possible water leaks.
3 Connect the end of the drainage pipe to the unit's
outlet pipe. Wrap the end of the pipe and securely
fasten it with a hose clamp.
