NOTICE!
Risk of damage to property from incorrect pipe
connections!
Take care to connect the pipes correctly as otherwise
the pipes and the drain trap may be damaged
beyond repair.
– Connect pipes in such a way that they are not
affected by vibration and that no loads are
imposed on them.
– If an AHU is installed outdoors, use suitable
pipes and protect them from frost.
1. Calculate the height of the drain trap as shown
above.
Fig. 30: Condensate drain
2. Remove the protective cap (Fig. 30/2) from each
drain (Fig. 30/1) of the condensate drip tray.

sure
3. Adjust the height of the drain tap based on the
above calculation. Drain traps for negative pres-
sure: Instead of shortening the pipe, you can
install the drain trap such that it slopes.
4. Connect a drain trap to each condensate drain
(Fig. 30/1).
Do not connect the drain trap to the drainage pipe;
the water from the drain trap should flow to a gully.
Air handling units to be installed outdoors or in
areas at risk of frost require frost protection for the
drain trap.
5.5 Connecting the heating coil/
cooling coil
Electric current
WARNING!
Danger of death due to electric current!
If electrical components come into contact with water
or a water glycol mixture, e.g. from a leak, you could
be seriously or even fatally injured. Water can also
cause damage to the air handling unit.
– Lay connecting cables in such a way that they
cannot be accidentally damaged by mechanical
impact or by heat.
– Do not lay connecting cables across electrical
components or switch cabinets as people may
become entangled in them.
Connect heat exchangers in a counter flow arrangement
unless a parallel flow arrangement has been specified
by the manufacturer. Only a counter flow arrangement
ensures that the calculated capacity is achieved.
If you have to attach brackets or fasteners to the
AHU panels or frame, use only those specially
approved for your AHU as otherwise there is a risk of
leakages.
