7. DUCT INSTALLATION
7.1. Pre-installation preparations
CAUTION
Procure a duct with internal diameter that ts the external diameter of the
duct ange.
Please note that regulations of some countries may require the use of a
nonammable duct.
If the duct penetrates a re-retarding division or other re-proong
measures, the installation of re dampers, or a construction that does
not adversely affect re control measures is a regulatory requirement of
some countries.
When using metallic ducts please ensure metals (i.e., metal lath, wire
lath, stainless sheeting) are electrically insulated.
(A short occurring by electrical connection can cause re)
Please ensure to thermally insulate connected ducts to prevent
condensation.
Please make certain that netting or other measures are installed in parts
exposed to the outside air to prevent inltration of small animals such as
birds and insects.
Please be certain to install external air lters to parts exposed to the
outside air for heat exchanger protection of indoor equipment.
Please avoid the inltration of rain water by installing outside ducts with
an incline of at least 1/30, and tting hoods on openings.
Be certain to use electric dampers and shutters to avoid inltration of
cold air, wind and fog during shutdown in areas with cold climates, strong
winds, or where fogs are common.
7.2. Duct installation
• Please fasten the connecting parts of the ducts with bands, and wrap with
vinyl tape to ensure no air leaks.
(Carry out the work to ensure no air leakage at a pressure of 200 Pa (0.03 psi))
• Please do not construct the duct in the manner of below.

8. DECORATION PANEL INSTALLATION
8.1. Installation of decoration panel
(1) Please connect extension wires for use with louvers, or extension wire
for optical receiver after provisional securing of the decoration panels.
(2) Tie the wires together with the cable tie provided and insert into the hole
of the Fresh Air Intake Kit.
(3) Install the wire-cover provided on the Fresh Air Intake Kit
(4) Please install decoration panel according to the installation instruction
sheet provided.

• Wire modication
Use a tool to cut off the terminal on the end of the wire, and then remove
the insulation from the cut end of the wire.
Connect the wire with connecting wire with solder.
IMPORTANT: Be sure to insulate the connection between the wires.
