REFRIGERANT PIPE CONNECTION
Securing of outdoor unit
Anchor the outdoor unit with
a bolt and nut 10 or 8 tightly
and horizontally on a concrete
or rigid mount.
If a drain elbow is used, the unit should be placed
on a stand which is taller than 3cm.
If the unit is used in an area where temperature
O
falls below 0 C for 2 or 3 days in succession, it
is recommended not to use a drain elbow, as the
drain water may freeze and the fan will not rotate.
Fit the seal into the drain elbow, then insert
the drain joint into the base pan hole of the
outdoor unit, rotate 90 to secure. Connect
the drain joint with an extension drain hose
(Locally purchased), in instances where you
need to drain condensed water away from the unit.

Main cause for refrigerant leakage
is due to defects in the flaring work.
Carry out correct flaring work
using the following procedure:
A: Cut the pipes and the cable.
1. Use the piping kit accessory (if applicable) or pipes
purchased locally.
2. Measure the distance between the indoor and the outdoor unit.
3. Cut the pipes a little longer than the measured distance.
4. Cut the cable 1.5m longer than the pipe length.

B: Burr removal
1. Completely remove all burrs from the cut
cross section of pipe/tube.
2. Face the end of the copper pipe/tube in a
downward direction as you remove burrs in
order to avoid burrs dropping into the tubing.
