Make sure that condensation drainage
can be conveniently routed away.
Do not install near a doorway.
Ensure that the space around the left and
right of the unit is more than 5cm. The
unit should be installed as high on the
wall as possible, allowing a minimum of
5cm from ceiling.

condenser is not restricted.
Ensure that the space around the back
and sides is more than 10cm. The front of
the unit should have more than 70cm of
space.
Do not place animals and plants in the
path of the warm air.

Mount the installation plate horizontally by
aligning the centerline using a level.

Mount the installation plate on the wall with
four type A screws. If mounting the unit on a
concrete wall, use anchor bolts.
The wall you select should be strong and solid
enough to prevent vibration.
B
Measure the wall and mark the centerline. It
is also important to use caution concerning
the location of the installation plate-routing of
the wiring to power outlets is through the
walls typically. Drilling the hole through the
wall for piping connections must be done
safely.

Completely remove all burrs from the cut
cross section of pipe/tube.
Put the end of the copper tube/pipe in a
downward direction as you remove burrs in
order to avoid dropping burrs into the tubing.
E
Compare the flared work with figure below.
If flare is noted to be defective, cut off the flared
section and do flaring work again.
C
Remove flare nuts attached to indoor and
outdoor unit, then put them on pipe/tube
having completed burr removal.
