Condensate drain
In heating mode the unit produces a significant quantity of
condensate, which must be suitably drained.
Proceed as follows:
• Connect the unit condensate drain
• Make sure the drain hose has a incline of at least 2 cm/m,
without obstructions or choking.
• Connect the condensate drain hose to a rainwater drain.
Do not connect to the sewage system as odours may be
sucked up if the water in the drain trap evaporates.
• After connecting, check correct drainage of the conden-
sate by pouring water into the pan.
• If necessary, suitably insulate the condensate drain hose.
• Condensate drainage must not cause problems to objects
or people.
• If the outside air temperature is less than 0°C, the conden-
sate may freeze.
Use hot wires on the condensate drain hose downstream of
the unit to protect against frost.

Fouling factors
The performance data given refer to conditions with clean
evaporator plates (fouling factor = 1).
For different fouling factors, multiply the figures in the perfor-
mance tables by the coefficient given in the following table.
f1: capacity correction factor
fk1: compressor power input correction factor
fx1: total power input correction factor
