Condensate drainage connection
If the temperature falls below the dewpoint on the
finned evaporator, condensation occurs during the
heating operation .
The condensate water must be drained off frost-
free via a condensation pipe with a diameter of at
least 50 mm.
n The condensate drainage line must be pro-
vided by the customer and have an incline of at
least 2 %. 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. If
necessary, the lower part of the housing and
condensate tray is to be kept frost free in order
to ensure permanent draining of the conden-
sate. If necessary, fit a pipe heater.
n If the substrate is permeable to water, it is suffi-
cient to lead the pipe vertically at least 90 cm
deep into the ground.
n In the case of condensate drainage in drains or
into the sewer system, the installation must be
frost-free and with an incline.
n The condensate may only be discharged into
the sewer system via a funnel siphon, which
must be accessible at all times.
Regional laws must be observed.
n Following installation, check that the conden-
sate run off is unobstructed and ensure that the
line is durably leak tight.
Pipe heater
A pipe heater can be mounted on water-carrying
pipes to ensure frost protection in the pipes.
Install a pipe heater if there is a risk of frost.
When installing on the mounting bracket or on a
foundation, we recommend the installation of a
pipe heater if the condensate drain or the inlet/
return flow heat pipes cannot be laid in a frost-free
manner or if they are heavily exposed to weather
conditions.
The pipe heater must be connected to a sepa-
rate power supply (UPS).
Heater for anti-freeze protection
The heater for anti-freeze protection is used to
control the temperature of the interior space of the
hydraulic unit. This ensures that in the event of a
fault, the last step in the freezing of the medium
and thus defects due to frost can be prevented. A
temperature of >+3 °C is established through recir-
culated air operation. It is essential that a separate
UPS is used for the power supply.
Safe drainage in the event of leakages
NOTICE!
Local regulations or environmental laws, for
example the German Water Resource Law
(WHG), can require suitable precautions to pro-
tect against uncontrolled draining in case of
leakage to provide for safe disposal of escaping
refrigerator oil or hazardous media.
NOTICE!
With the connection of an external drain line to
the oil separator, it must be kept frost-free.
