Multi bend
Reduced diameter. Do NOT reduce the duct diameter.
▪ The minimum bend radius for flexible ducts is as follows:
(Øduct/2)×1.5
▪ To prevent air leakage, wind aluminium tape around the section
where the duct flanges and the ducts are connected.
▪ Install the opening of the supply air as far as possible from the
opening of the room air.
▪ Use ducts with a diameter that fits the unit model. See the data
book.
▪ Install the two outdoor ducts with a downward slope (minimum
1:50) to prevent entry of rain water. Also provide insulation for
both ducts, to prevent dew formation. (Insulation material: 25 mm
thick glass wool)
▪ If the temperature and humidity levels inside the ceiling are always
high, install ventilation inside the ceiling.
▪ Insulate the duct and the wall electrically when a metal duct has to
penetrate the metal lattice and wire lattice or the metal lining of a
wooden structure wall.
▪ Install the ducts in such a way that the wind CANNOT blow inside
the ducting.
▪ All 4 ducts MUST have a length ≥1.5 m (exception: VAM in
combination with optional EKVDX, see EKVDX operation and
installation manual).

NOTICE
When using residual current operated circuit breakers,
make sure to use a high speed type 300 mA rated residual
operating current.
NOTICE
The power supply MUST be protected with the required
safety devices, i.e. a main switch, a slow blow fuse on
each phase and an earth leakage protector in accordance
with the applicable legislation.
