Air Duct Installation
6.1 Piping Design and Installation
1) In order to prevent short-circuit air delivery, the piping for air outlet and air
inlet ducts must not be too close.
2) The indoor unit does not have an air filter installed. The air filter must be
installed at a location like an air inlet where it can be easily maintained.
(Without an air filter, dust particles may stick to the air heat exchanger which
will make the air conditioner prone to failures and water leakage.)
3) Before installing the air duct, ensure that the static pressure of the air duct
is within the permitted range of the indoor unit (Refer to the IDU technical
manual). Figure 6.2 to Figure 6.10 show the static pressure curve for indoor
units.
4) Connect the canvas duct to the air return and air outlet ducts to prevent
vibrations from the indoor unit transferring to the ceiling.
5) Use heat insulation materials at a thickness of 25 mm or more to prevent
condensation on the air duct.
6) Connect the air duct as shown in Figure 6.1. On-site preparation required for
all components except for the air conditioner.

Caution
•
Once the air conditioner body and the canvas joints are riveted together,
the flange plate of right sizes must be secured with screws. (M6 x 12
screws are prepared on site.)
