Installation
Check
1. Compare the flared work with the figure by.
2. If a flared section is defective, cut it off and
do flaring work again.
Indoor
1. Prepare the indoor unit's piping and drain hose
for installation through the wall.
2. Remove the plastic tubing retainer(see the
illustration by) and pull the tubing and drain
hose away from chassis.
3. Replace only the plastic tubing holder 1, not
the holder 2 in the original position.
1. Route the indoor tubing and the drain hose in
the direction of rear right.
2.
Insert the connecting cable into the indoor unit
from the outdoor unit through the piping hole.
• Do not connect the cable to the indoor unit.
• Make a small loop with the cable for easy
connection later.
3. Tape the tubing, drain hose, and the
connecting cable. Be sure that the drain hose
is located at the lowest side of the bundle.
Locating at the upper side can cause drain
pan to overflow inside the unit.
If the drain hose is routed inside the room,
insulate the hose with an insulation material*
so that dripping from "sweating"(condensation)
will not damage furniture or floors.
*Foamed polyethylene or equivalent is
recommended.
