■Drain Piping of Ceiling Cassette

•Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow.

•During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit.

•The outside diameter of the drain connection on the indoor unit is 32mm(1.26inch).

Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings

•Be sure to install heat insulation on the drain piping.

Heat insulation material: Polyethylene foam with thickness more than 8 mm(0.31inch).

■Install the drain raising pipes at a right angle to the indoor unit and no more than 300mm(11.81inch) from the unit.
