Make sure the installation of the duct does NOT exceed the setting range of the
external static pressure for the unit. Refer to the technical datasheet of your
model for the setting range.

Make sure to install the canvas duct so vibrations are NOT transmitted to the
duct or ceiling. Use a sound-absorbing material (insulation material) for the lining
of the duct and apply vibration insulation rubber to the hanging bolts.
▪
When welding, make sure NOT to spatter onto the drain pan or the air filter.

If the metal duct passes through a metal lath, wire lath or metal plate of the
wooden structure, separate the duct and wall electrically.
