Connecting the condensate drain
The Unit condensate drain should be connected to building's indoor sewerage system. If condensate
drain is installed in non-heated premises or directed outdoors, it must be thermally insulated or
equipped with electric heater.
Install a round rubber gasket into the condensate drain socket, then firmly screw the condensate drain
nozzle in by hand.
Figure 5. Installing the condensate drain
IMPORTANT!
Do not use pliers or other similar tools, as excess power applied may damage the unit.
Mechanical damage will void the warranty.
The necessary incline of the condensate drain should be ensured during the installation: at least 2°
incline should be ensured in the horizontal part of the system, refer to Figure 6. Connecting the
condensate drain".
Siphon with non-return valve is the obligatory part of the condensate drain system. It is
recommended to use HL138, HepvO or similar type, internally or externally mounted siphon. Siphon
should be installed according to Figure 6 "Connecting the condensate drain", ensuring that the siphon
manufacturer's instructions on incline, distances, necessary inspection hatch for the selected siphon
model are observed.
