Flaring Work and Connection of Piping
Check
1. Compare the flared work with the figure on
the right.
2. If a flared section is defective, cut it off and
repeat the flaring process 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 on the right) and pull the tubing
and drain hose away from chassis.
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 on cable. Be sure that the drain
hose is located on the lowest side of the
bundle. Locating on the upper side can cause
the condensation to overflow in the drain pan
inside the indoor 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.
