3 DRAIN PIPING WORK

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 VP20
	(Outer dia. : Ø26mm)
Heat insulator	Foam polyethylene :
	Thickness 10mm or more

REQUIREMENT

•	Be sure to perform heat insulation of the drain pipes of the indoor unit.	1.5m to 2m	Support
•	Never forget to perform heat insulation of the connecting part with the indoor		bracket
	unit. An incomplete heat insulation causes dewing.

•Set the drain pipe with downward slope (1/100 or more), and do not make 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.

As long as possible (10cm)

Extended ventilating pipe

•Set the collective piping as shown in the right figure.

•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.

Adhesive agent		VP20 vinyl chloride pipe
prohibited		(procured locally)

Adhesive inhibited :

Use the attached flexible hose and hose band for connecting the drain hose to the clear drain socket.

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

Drain up

When not securing down slope on the drain pipe, use a drain up kit sold separately.

Also refer to the “Drain up kit installation manual”.

The drain pipe can be raised 60cm from the top face of the main unit.

* When using drain up kit, both drain pipe and refrigerant pipe can be taken only from upper side.
