Compact Ventilation Units AIR1 XC
Four or six mounting brackets (see Fig. 5) with vibration dampers (included in scope of delivery) are mounted to the unit
for ceiling installation. The ceiling installation takes place e.g. with threaded rods (see Fig. 6) or appropriate mounting
accessories.
2�2�2 Condensation outlet
The humidity of extract air condenses to water during the heating period. A lot of condensate can build up in new buil-
dings with large numbers of people. The condensate collected in the stainless steel condensation tub is discharged via
two condensation outlets.
The drainage pipe route must not rise above the siphon!
Condensate water can be easily removed from the condensate piping. If the automatic discharge of condensate
water is not ensured, a suitable condensate pump (accessories) must be used.
The condensation outlet must be made frost-proof!
The unit has two condensation outlet pipes for the weather conditions in winter (1 /Fig. 9, Fig. 10) and summer (2 /
Fig. 9, Fig. 10).
It must be ensured that the condensation outlet pipes are connected separately.
– Existing drainage systems must not be directly connected to the waste water system.
The condensate water pipes must only be connected to the waste water system via an odour trap (siphon). The con-
densate must flow freely into the waste water system after the siphon.
A flexible condensate connection to the unit is recommended, since it must be removed during maintenance work on
the heat exchanger.

2�2�3 Flange connection / adapters
The dimensions for the unit flange connections can be found in Fig. 8 and the following table.
With regard to the flange connection for unit AIR1 XC 3200, a mounting bracket must be used (mounting bracket inclu-
ded in scope of delivery. A special mounting bracket is included in scope of delivery for certain accessories).
The ducting must be firmly and tightly connected to the connection valves.
2�2�4 Air ducting, ventilation circuit
When designing the ductwork, use the shortest possible runs. Airtight connections and changeovers must be ensured
for the best possible heat recovery.
Outside and outgoing air pipes are to be insulated in an appropriate way to reduce condensation.
If supply and extract air ductwork runs through unheated rooms, insulation must be provided to reduce heat losses.
All fire protection regulations must be observed!
