Condensate drain
The condensate must be disposed in order to avoid damages to
people and things.
 Unit discharge fitting: the connection must not transmit
mechanical stresses and must be performed taking care not to
damage the unit discharge fitting.

Provide a siphon that, eliminating the negative pressure caused
by the fan, prevents the air intake from the discharge duct.

The connection between the attachment and the siphon must
be hermetically sealed (A)

The piping must have adequate slope to allow out flow.

Anchor the ducting with an adequate number of supports..
Otherwise are generated duct failures and air locks that
prevent the runoff.
 Insulate the duct and the siphon to avoid the condensate
drippings.
 Connect the condensate discharge to a sewerage drainage
network.
 DO NOT use white water or drainage networks to avoid the
aspiration of odours in the case of evaporation of water
contained in the siphon.
 Check at the end of the work, the regular condensate runoff
pouring some water in the tray.
Siphon height calculation
T = 2P
S = T/2
P is the pressure determined by the fan in correspondence of the
condense collection bowl (approx. 1 mm = 9.81 Pa)
Example :
P = 300 Pa = 30 mm
T = 2P = 60 mm
S = T/2 = 30 mm
Condensation in winter operation
When a heat pump is running it produces a considerable amount
of water due to the defrosting cycles of the external coil.
The condensate must be disposed in order to avoid damages to
people and things.
Risk of freezing
Prevent the risk of freeze if the unit, drain or plumbing
connections can be subject to temperatures close to 0°C.
 isolate the piping
 protect the piping with heating cables laid underneath the
insulation
