INSTALLING THE DUCT

Connect the duct supplied in the field.

Air inlet side

• Attach the duct and intake-side flange (field supply).
• Connect the flange to the main unit with accessory screws (in

20 or 24 positions).

• Wrap the intake-side flange and duct connection area with

aluminum tape or something similar to prevent air escaping.

CAUTION

When attaching a duct to the intake side, be sure to attach an
air filter inside the air passage on the intake side. (Use an air
filter whose dust collecting efficiency is at least 50% in a gravi-
metric technique.)
The included filter is not used when the intake duct is attached.

Air outlet side

• Connect the duct according to the air inside of the outlet-side

flange.

• Wrap the outlet-side flange and the duct connection area

with aluminum tape or something similar to prevent air
escaping.

CAUTION

• Be sure to insulate the duct to prevent condensation from form-

ing. (Material: glass wool or polyethylene foam, 1 in. thick)

• Use electric insulation between the duct and the wall when

using metal ducts to pass metal laths of the net or fence
shape or metal plating into wooden buildings.

• Be sure to explain about the way of maintaining and cleaning

local procurements (air filter, grille (both air outlet and suction
grille), etc.) to your customer.

ELECTRIC WIRING WORK

9-1 GENERAL INSTRUCTIONS

• Shut off the power before doing any work.
• All field supplied parts and materials, electric works must

conform to local codes.

• Use copper wire only.
• See also the “Wiring Diagram label” attached to the control

box lid when laying electrical wiring.

• For details on hooking up the remote controller, refer to the

“REMOTE CONTROLLER INSTALLATION MANUAL”

• All wiring must be performed by an authorized electrician.
• This system consists of multiple indoor units. Mark each

indoor unit as unit A, unit B . . . , and be sure the terminal board
wiring to the outdoor unit and BS unit are properly matched. If
wiring and piping between the outdoor unit and an indoor unit
are mismatched, the system may cause a malfunction.

• Install a wiring interrupter or ground-fault circuit interrupter

for the power wiring.

• Make sure the ground resistance is no greater than 100

Ω

• To avoid short circuiting the power supply wire, be sure to use

insulated terminals.

• Do not turn on the power supply (wiring interrupter or ground-

fault circuit interrupter) until all other work is done.

DANGER

• Do not ground units to water pipes, telephone wires or light-

ning rods because incomplete grounding could cause a
severe shock hazard resulting in severe injury or death, and
to gas pipes because a gas leak could result in an explosion
which could lead to severe injury or death.

9-2 LIST OF STANDARD WIRING EQUIPMENT

NOTES

1. If the wiring is in a place where people it can be easily

touched by people, install a ground-fault circuit interrupter to
prevent electric shock.

2. When using a ground-fault circuit interrupter, make sure to

select one useful also to protection against overcurrent and
short-circuit.
When using a ground-fault circuit interrupter only for
grounding device, make sure to use a wiring interrupter
together.

• The length of the transmission wiring and remote controller

wiring are as follows.
