DRILL 3 INCH HOLE FOR PIPING/WIRING/DRAIN
•
Locate the center where the hole will need to be drilled.
•
Drill the holes of 2.5
– 3 Inches in diameter. A down pitch of
about 1/4 inch per foot, as illustrated, is needed for the hole,
to drain the condensate properly.
PREPARE INDOOR UNIT- COPPER LINE SET/DRAIN HOSE
•
If pipes need to come out of the right side (facing
the front of indoor unit) of the indoor unit, snap off
portion (1) on plastic casing.
•
If pipes need to come out of the bottom side (facing
the front of indoor unit) of the indoor unit, snap off
portion (2) on plastic casing.
•
If pipes need to come out of the left side (facing the
front of indoor unit) of the indoor unit, snap off portion
(3) on plastic casing.
•
If pipes need to be rerouted to a different direction from
the one preset at factory (towards left side, if facing the
front cover of indoor unit), lay the indoor unit down on a
soft cushion or foam. Don't rub the plastic casing.
•
To keep from damaging the pipes, bend the copper tubing set gently and slowly (A 90° bend should take a
minimum of 10 seconds), by firmly holding the pipe at the root of the original 90° bend. Don't rub the two copper
lines while bending. It is better to cut off the insulation and bend the two pipes individually and not together.
•
If the pipes need to come out of the rear side (facing the front of the indoor unit) of the indoor unit, there is no
need to snap off anything.
INSTALL THE INDOOR DRAIN PIPE
•
The drain hose must be placed beneath the copper
pipes and MUST NOT be kinked or bent sharply.
•
Do not pull the drain hose too hard, as it may break.
•
Before passing the drain hose through the hole, wrap
it with insulation to keep it from possible damage.
•
The copper pipe and the drain hose must be wrapped
with piping wrap.
•
The insulation pad (underlay) should be used where the
pipe contacts the wall.
