As long as possible (10cm)

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 VP25
	Piping	(Outer dia. : Ø32mm)
		(Outer dia. : Ø32mm)

	Heat insulator	Foam polyethylene :
	Heat insulator	Thickness 10mm or more
		Thickness 10mm or more

REQUIREMENT

•

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

1.5m to 2m

Support

bracket

•

Never forget to perform heat insulation of the connecting part with the indoor

unit. An incomplete heat insulation causes dewing.

Heat

1/100 or more

•

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

downward

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.

•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 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.

Flexible hose

Use the attached flexible hose to adjust core discrepancy of the hard vinyl chloride pipe or to adjust the angle.

•Do not use the flexible hose as stretched, or do not deform it more extent than that in the following figure.

•Be sure to fix the soft end of the flexible hose with the attached hose band.

•Use the flexible hose on a horizontal level.
