Shut-off valves
As a rule, in cold water systems, shut-off valves
with full admission should be used. For the pur-
pose of servicing, medium inlet and medium outlet
must be equipped with shut-off valves (if necessary
safety valves).
Air bleeding valves
The unit has manual air bleeding valves. The unit
can be bled separately after the system has been
filled. Automatic bleeding valves must also be
installed at the highest point in the collector line.
NOTICE!
Glycol tolerant air bleeding valves are neces-
sary when using media that contain glycol.

Condensate drainage

drainage
Condensate drainage connection
If the temperature falls below the dew point, con-
densation may form on individual components and
can be collected and drained off.
Taking the water resources act into account, it is
necessary to check locally whether a condensate
tray with oil separator is to be installed under the
unit. This may need to be provided by the cus-
tomer.
n
The condensate drainage line should have an
incline of min. 2% and is the responsibility of
the customer. If necessary, fit vapour-diffusion-
proof insulation.
n
When operating the unit at outside tempera-
tures below 4 °C, ensure the condensate
drainage line is laid to protect it against frost.
The lower part of the housing and condensate
tray is also to be kept frost free in order to
ensure permanent draining of the condensate.
If necessary, fit a pipe heater.
n
Following installation, check that the conden-
sate run off is unobstructed and ensure that the
line is durably leak tight.
Safe drainage in the event of leakages
Local regulations or environmental laws, for
example the German Water Resource Act (WHG),
can require suitable precautions to protect against
uncontrolled drainage in case of leakage to provide
for safe disposal of escaping air conditioning fluid
or hazardous media.
Unit connections
The unit has 2 brass connections where the con-
densate can be collected and drained off.
The connection installed in the right-hand corner is
used both to drain off rainwater collected in the unit
and to provide a means of draining the operating
medium, which can also be drained centrally via
this connection if the unit is drained using shut-off
valves.
The condensate water arising on the components
can be drained off via the central connection.
