„
Lift the air/water heat exchanger and position it by in-
serting the threaded bolts into the corresponding
holes in the enclosure.
„
Fit appropriate washers and screw hexagon nuts onto
the threaded bolts (tightening torque: 2.5 Nm).

5.3.4 Connecting the condensate water dis-
charge
The hose
– must be laid with a suitable and constant gradient (no
siphoning),
– must be laid without kinks and
– must not have a reduced cross-section if extended.

1 Cooling water connection (inlet)
2 Cooling water connection (return)
3 Condensate water discharge
„
Fit a suitable flexible hose (dia. 12 mm, 1/2") onto the
condensate nozzle as shown in fig. 8 (bottom of the
unit).
„
To prevent the water from backing up, the hose cross-
section must not be restricted.
5.4 Connecting the water connection
A fixed pipe connection with G⅜" external thread is pro-
vided at the air/water heat exchanger for the water inlet
and water return.
„
Place the enclosed flat seals on the HD fittings.
Hygiene risk!
To avoid germ formation, a drain hose must
be provided specifically to drain any conden-
sate from the unit.
The hose must be removed at regular inter-
vals to enable external cleaning of the con-
densate nozzle.
If the unit is installed in a food area as defined
by DIN EN 1672-2, the hose used must be of
a food-compatible material.
Hygiene risk!
The hose should not end in a pipe or floor
drain. There is otherwise a risk of germ for-
mation and bacterial growth in the hose.
For simple cleaning, observe a distance of
5 mm between the end of the hose and the
bottom of the unit (fig. 8).
Hygiene risk!
The flat seals serve primarily to seal the gap
at the connection and enable simple clean-
ing.
