3. Using a 65mm core drill, drill a hole in the wall. Make sure
that the hole is drilled at a slight downward angle, so that
the outdoor end of the hole is lower than the indoor end
by about 12mm. This will ensure proper water drainage
(See Fig. 6.4) . Place the protective wall cuff in the hole.
This protects the edges of the hole and will help seal it
when you finish the installation process.

NOTE: When drilling the hole, make sure to avoid wires,
plumbing, and other sensitive components.
4. Pass the drain hose through the wall hole. Make sure the
water drains to a safe location where it will not cause water
damage or a slipping hazard.
NOTE: The drainpipe outlet should be at least 5cm above
the ground. If it touches the ground, the unit may become
blocked and malfunction. Make sure that the drain has a
U or S pipe to catch odours that might otherwise come
back into the house.
NOTE: When connecting multiple drainpipes, install the
pipes as shown in
Fig. 6.5.

Drainage pump test procedure
Check that the drainpipe is unhindered. This test should be
performed on newly built houses before the ceiling is surfaced.
1. Remove the test cover. Fill the water pan with 2 litres
of water.

2. Turn on the unit in COOLING mode. You will hear the drain
pump. Check whether the water is discharged properly
(a 1 minute lag is possible, depending on the length of the
drain pipe). Check whether water leaks from the joints.
3. Turn off the air conditioner and put the cap back on.
