CAUTION
▪
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.
▪
Install the outlet grille in a position where the airflow will not come into direct
contact with people.
▪
Do NOT use booster fans in the duct. Use the function to adjust the fan rate
setting automatically (see
The ducting is to be field supplied.

3 Wind aluminium tape around the flange and duct connection on both sides.
Make sure there are no air leaks at any other connection.
4 Insulate the duct to prevent condensation from forming. Use glass wool or
polyethylene foam 25 mm thick.
▪ Filter. Be sure to attach an air filter inside the air passage on the intake side. Use
an air filter with dust collecting efficiency ≥50% (gravimetric method). The
included filter is not used when the intake duct is attached.
Make sure condensation water can be evacuated properly. This involves:
