(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 situations, 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 bottom using the large sealing pad (8).

(Refer to Fig. 23)

• Be sure to insulate all drain piping running indoors.

Note: • To ensure no excessive pressure is applied to the drain pipe (1), do not bend or twist when

installing. (This may cause leakage.)
