• When piping is complete, cut the removed penetration lid into

the shape of the pipe using scissors and attach.

As when before removing the top penetration lid, secure the

lead lines for the swing motor and thermistor by passing them

through the clamp section on the top penetration lid.

(Refer to Fig. 18, 20)

• When doing this, block any gaps between the pipe penetra-

tion lid and the pipes using putty to prevent dust from enter-

ing the indoor unit.

7. DRAIN PIPING WORK

(1) Carry out the drain piping.

• Make sure piping provides proper drainage.

• You can select whether to bring the drain piping out from the

rear right or right. For rear right-facing and right-facing situa-

tions, refer to “6. REFRIGERANT PIPING WORK” on page 7.

• Make sure the pipe diameter is the same or bigger than the

branch piping. (vinyl-chloride piping, nominal diameter 1 in.,

external diameter 1 1/4 in.)

• Make sure the piping is short, has at least a 1/100 slope, and

can prevent air pockets from forming. (Refer to Fig. 21)

• Do not allow any slack to gather in the drain pipe inside the

indoor unit.

(Slack in the drain pipe can cause the suction grille to break.)

CAUTION

• Water accumulating in the drain piping can cause the drain to

clog.

• Be sure to use the drain pipe (1) and metal clamp (2).

Also, insert the drain pipe completely into the drain socket, and

securely attach the metal clamp bracket inside the gray tape

area on the inserted tip of the drain pipe. (Refer to Fig. 22)

Screw the screws on the metal clamp bracket until there is 5/

32 in. left. (Pay attention to the direction of the attachment to

prevent the metal clamp bracket from coming into contact

with the suction grille.) (Refer to Fig. 23)

• Insulate the metal clamp bracket and drain pipe from the bot-

tom using the large sealing pad (8). (Refer to Fig. 23)

• Be sure to insulate all drain piping running indoors.

(2) Check to make sure the water flows smoothly after pip-

ing is complete.

• Slowly pour 600 ml of drain-checking water into the drain pan

through the air outlet.

CAUTION

• Drain piping connections :

Do not connect the drain piping directly to sewage pipes that

smell of ammonia. The ammonia in the sewage might enter

the indoor unit through the drain pipes and corrode the heat

exchanger.
