Installation Manual

nWire connection change of fan motor

This duct is composed of 3 fan motors.

To change external static pressure by duct resistance, connect the 3 connectors of the orange lead wires that are connected to the underside of the fan tap changing terminal block to the same number (F1, F2 or F3) terminal.

The wires of the fan motor has been connected to (F2) [External static pressure 137Pa (14mmAq)] as factory default.

Installation Manual

6 DRAIN PIPING WORK

CAUTION

Following the Installation Manual, perform the drain piping work that water is properly drained, and apply a heat insulation not to cause a dew condensation.

Inappropriate piping work may cause the water leakage in the room and wet of furniture.

REQUIREMENT

•The drain piping flows the natural drainage. Make sure to set the drain piping from the unit with descending slope of 1/50 to 1/100 and do not make up-down or trap in the midway.

•Set the horizontal pulling of the drain pipe to 20m or less. When drain piping is too long, attach the support bracket at intervals of 1.5m to 2m to avoid the pipe becomes undulant as shown in figure below.

<Example for installation of the main piping (Incl. piping support)>

1.5 to 2 m

As long as possible

NOTE

When the external static pressure is changed, write down the static pressure once change in the wiring diagram of the indoor unit is made.

•Be sure to connect the drain pipe to the air conditioner with adhesive to avoid water leakage from the joint portion.

•Condensation may occur on the drain pipes including collective pipes.

All drain pipes must be wrapped with heat insulator to prevent dew condensation.

Especially a part where drain pipe is connected to the indoor unit must be firmly insulated with the provided heat insulator.
