PENETRATION OF WALL FOR TUBING

1. Mark the location of the hole on either side of the mounting
plate as shown. and drill it at a 5 downward angle, as shown.
2. The hole is drilled at an angle, to prevent condensed or rain
water from penetrating back into the room.
3. Trim the hole in the wall with a

SUSPENDING AND RELEASING THE UNIT FROM THE
MOUNTING PLATE
1. Make sure that the refrigerant tubes, electric cables and condensate
water hos e are well insulated with closed cell rubber based insulating
tubes(6 mm thickness), are wrapped together with UV stabilized non-
adhesive plastic tape, and are passed through the hole in the wall.
2. Hang the indoor unit on the two hooks that are located near the top
edge of the mounting plate.
3. Press the lower part of the indoor unit against the mounting plate
until the catches snap into the slots and lock the indoor unit to the
mouting plate.
4. Check the installation by pulling the unit towards you.
5. To release the unit from the mounting plate, lift up the unit and then
pull the unit towards you, to ensure that the hooks are locked.

CONDENSATE HOSE
CONNECTION
1. Attach the condensate drain hose to the corrugated hose in the
rear groove of the indoor unit.
2. Wrap the drain hose
together with the
refrigerant tubes and
electrical cables.
3. Ensure that the
condensate drain
hose is at all points
installed in a
downward slope
manner.
4. When installing the
drain hose avoide
traps and U-bends.
The end of the drain
hose should not be
immersed in water.
5. For a lefthand outlet,
lay the drain hose on
the bottom of the
indoor unit rear
groove.
6. When the installation
location requires long
horizontal sections, a
vent must be provided
at the top of the hose
to prevent overflow of
the unit drain pan.
7.Upon completing the installation, test the water drain by pouring
at least two liters of water into the unit drainpan. Check that the
water drains off.
