4 DRAIN PIPING WORK

Connection of drain hose at indoor unit side

1.	Insert the drain hose attached to the indoor unit into
	the drain pipe connecting port of the indoor unit’s
	and into the drain pipe connecting port of the drain
	up kit’s drain pan.
	In this time, insert the drain hose until it strikes on
	the connecting port of the drain pipe.
2.	Align the hose band attached to the indoor unit with
	the end of pipe connecting port, and then tighten it

Connection of drain hose at drain up kit side

1.	Insert the drain hose attached to the drain up kit
	into the connecting port of drain pipes at the upper
	side of the drain up kit.
2.	Align the hose band attached to the drain up kit with
	the end of pipe connecting port, and then tighten it
	firmly.
3.	Fit the drain connecting thermal insulator attached
	to the drain up kit to sheet metal at the upper side

CAUTION

•Following the Installation Manual, perform the drain piping work so that water is properly drained, and apply a heat insulation so as not to cause a dew. Inappropriate piping work may result in water leakage in the room and wet of furniture.

Piping/Heat insulating material

Require the following materials for piping and heat insulating at site.

Piping	Hard vinyl chloride pipe VP25

Heat insulator	Foam polyethylene :
	Thickness 10mm or more

3. Cut off (to 160 × 200) the thermal insulator (200 ×

200) for drain hose attached to the indoor unit.

Using it, lap the connecting section of drain pan and

drain hose without clearance, and then tighten it

with two banding bands attached to the indoor unit

so that thermal insulator does not open.

•Be sure to perform heat insulation of the drain pipes of the indoor unit.

•Never forget to perform heat insulation of the connecting part with the indoor unit. An incomplete heat insulation causes dewing.

• Set the drain pipe with downward slope (1/100 or more), and do not make insulator swelling or trap on the piping. It may cause an abnormal sound.

•For length of the traversing drain pipe, restrict to 20m or less. In case of a long pipe, provide support brackets with interval of 1.5 to 2m in order to prevent waving.

Fit the drain connecting thermal insulator to sheet metal at the upper side of the drain up kit, and then lap it without clearance.

•Be sure not to apply force to the connecting part of the drain pipe.

•The hard vinyl-chloride pipe cannot be directly connected to the drain pipe connecting port of the indoor unit.

For connection with the drain pipe connecting port, be sure to use/fix the attached flexible hose with the hose band, otherwise a damage or water leak is caused on the drain pipe connecting port.

Use the attached flexible hose and hose band for connecting the drain hose to the drain piping connecting part.

If applying the adhesive, socket will be damaged and cause water leakage.

Adhere the ceiling thermal insulator attached to the drain up kit to positions of the refrigerant pipe and the drain pipe.

Connection of drain pipe

•Connect hard vinyl chloride pipe (procured locally) to the attached drain hose which has been installed.
