5.4 Connecting the condensation
drain
The plate exchanger and cold water battery must
each be placed in a condensate tray. The plate
exchanger condensate tray features a fitted
membrane siphon as standard. The membrane
siphon connects to a plastic 32mm drain through
which condensation can be drained directly.
The cold water battery is located in a condensate
tray, fitted with a 32mm plastic drain. A membrane
siphon must be connected to this plastic drain on
site.
The membrane siphon does not lock the output pipe
with a water lock, but with a self-locking valve.
Siphon heating
Siphons are sensitive to frost. A siphon heater
reduces the risk of frost damage.
Take account of the following factors when fitting the
condensation drain:
■ The condensation must be drained off frost-free,
at a gradient, using an appropriate siphon;
■ The membrane siphon must be mounted at an
angle of 45°;
■ Connect the condensation drain (air-tight) via a
pipe or a hose to the sanitary pipework;
■ Spray or blow the siphon to loosen the non-return
valve.

5.5 Electrical connections

The connection must comply with national
equivalent CEN standards and the locally applicable
regulations.
The operating switch can be locked with a padlock.
This prevents unintended activation during
maintenance activities.
The ComfoAir diagrams are located between the
technical specification sheets.

5.6 Connecting the battery

Compressed air connection
Tighten coupling
Hold connection stump
■ The connections must be counterflow connected
as indicated on the ComfoAir (+ = input; - =
output);
■ When connecting the battery, the piping system
must be fitted with a good vent and drainage
system directly outside the ComfoAir;
■ When tightening the connections to the battery,
the connecting stump must be held firmly in order
to avoid the battery connection being bent or
rotated, as this might otherwise result in serious
damage;
■ Ensure the connection hoses are not in front of
the operating doors, as this might hinder the
checking and maintenance process.
Warning for hot water battery!! Its medium
is warm or hot water under excess pressure
"Danger of burns".
