12.2.2 Guidelines when installing the ducting
WARNING
Do NOT install operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater) in the duct work.
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
"16.1 Field setting" [
4
18]).
The ducting is to be field supplied.
1 Connect the canvas duct to the inside of the flange on both inlet
and outlet side. For connecting the canvas duct, use accessory
screws.
2 Connect the duct to the canvas duct.
