CONNECTING THE CONDENSATE DISCHARGE PIPE
(For air handlers which can operate in cooling mode)
• Connect the condensate pipe to a discharge pipe.
• Fix the two pipes using adhesive tape:
- MW 2, MW 3: Ø 18 mm.
- MW 4, MW 5: Ø 26 mm.
• For air handlers equipped with a condensate lift system, the pump discharge is
connected to a flexible PVC pipe of internal diameter 6 mm, equipped with a splined
connector.
See the "Technical Manual" for the pressures available at the discharge.

HYDRAULIC CONNECTION
• MW can be connected either with metric copper pipe or with PER
(interlaced polyethylene).
• Diameter of the pipes to be used:
- MW 2 and MW 3:
- copper pipe 10/12 or
- PER pipe 10/12
- MW 4 and MW 5:
- copper pipe 14/16 or
- PER pipe 13/16
• Adaptors for copper pipe or PER pipe are supplied with the air handler.

IMPORTANT NOTE
• If the end of the condensate discharge pipe goes into the
water and forms a trap, the flow will not be correct and the
condensate will flow in the internal unit (see drawing
opposite).
• Check that the condensate is discharged smoothly.
• Seal the hole in the wall through which the pipes pass in
order to prevent water entering.
• Using a bottle, pour water into the condensate tray in order
to ensure that the water is correctly discharged.

P.E.R. pipe
• For orientations 1 cut the plate (in
order to put the pipes through leaving
the contour free from any roughness).
• Keep the piece of plate cut for possi-
ble later use.
