NOTICE
Do NOT install the unit tilted. Possible consequence: If
the unit is tilted against the direction of the condensate flow
(the drain piping side is raised), the float switch might
malfunction and cause water to drip.

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
See "2 Specific installer safety
sure this installation complies with all safety regulations.
Minimum duct lengths:
▪ Supply air duct between VAM and EKVDX:
▪ for VAM500J8+EKVDX32A2: ≥500 mm
▪ for all other combinations: ≥750 mm
▪ Minimum outdoor air, return air and exhaust air duct length:
≥1.5 m
▪ Ducting after EKVDX: no minimum length limit
The ducting must be field supplied.
1 Connect the canvas duct to the inside of the flange on the outlet
side. For connecting the canvas duct, use accessory screws.
2 Connect the duct to the canvas duct.

Make sure there are no air leaks at any other connection.
4 Insulate the inlet and outlet ducts to prevent condensation. Use
glass wool or polyethylene foam 25 mm thick.
12.2.3 Guidelines when installing the drain
piping
▪ Pipe length. Keep drain piping as short as possible.
▪ Pipe size. Keep the pipe size equal to or greater than that of the
connecting pipe (vinyl pipe of 20 mm nominal diameter and
26 mm outer diameter).
▪ Slope. Make sure the drain piping slopes down (at least 1/100) to
prevent air from being trapped in the piping. Use hanging bars as
shown.
1~1.5 m

Not allowed
▪ Condensation. Take measures against condensation. Insulate
the complete drain piping in the building.
▪ Rising piping. If necessary to make the slope possible, you can
install rising piping.
▪ Drain hose inclination: 0~75 mm to avoid stress on the piping
and to avoid air bubbles.

▪ Combining drain pipes. You can combine drain pipes. Make
sure to use drain pipes and T-joints with the correct gauge for the
operating capacity of the units.
