15. Installation
(5) Remove unit from carton and carefully place the unit's mounting bolts into the bracket-hanger's slot.
After all the four (4) bolts are in the slots, push the unit towards bolts slowly. Secure the unit on the bracket-
hanger by tightening all the four (4) bolts.
Condensate drain
(1) The unit should be at the reasonable level and pitched toward the drain, so as to ensure proper drainage.
(2) Connect the soft hard vinyl chloride pipe to the coupling, see fig.4
(3) Drainage is done by gravity effect, therefore the piping outside the unit should have a slope downwards.
(4) Avoid draining as shown in fig.5
Refrigerant piping
(1) Indoor unit should have flared connections.
(1.1) Make flare joints for both suction and liquid line .
(1.2) Ensure tube and fitting are in line before tightening the nut to provide concentric seating of tube on fit-
ting to prevent leakage.
(2) The pipes can be bend around the rear as shown in figure 4.
(3) Brazing should be performed with a constant purge of nitrogen through the piping. This is to keep inside of
tubing clean.
(4) Insulate suction and liquid line separately to prevent sweating .
(5) Use two spanners to connect the flare nut connections. See fig.5
