NOTE

Be sure to follow the instructions as below.

• Do not connect the drain piping directly to a sewer that smells of ammonia.

The ammonia in the sewer may reach through the drain piping and corrode the heat exchanger of the

indoor unit.

• Do not bend or twist the provided drain hose (2) in order not to impose excessive force on the hose.

(Doing so may result in water leakage.)

• Take the procedure shown in the following illustration to perform concentrated drain piping.

• Select the diameter of the concentrated drain piping to suit the capacity of equipment connecting to the

concentrated drain piping (see the equipment design sheet).

(3)

Check the smooth draining of the piping on completion of the installation of the piping.

• Provide approximately one liter of water gradually into the drain pan through the water inlet on the

bottom of the drain socket or the outlet.

(4) Be sure to conduct heat insulation work on the following portions, or otherwise water leakage may

occur as a result of dew condensation.

• Drain piping indoors

• Drain socket

The drain piping will be clogged with

water and water leakage may result if the

water is accumulated in the drain piping.

Maintain a downward slope of at least

1/100 so that no air bank will be formed.
