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
using a ball siphon (included in the scope of delivery). In this respect, there must be an incline of at least 3° and the
customer must ensure the connection to the local drainage system. An open outlet should be installed due to odour
development from a dried-out siphon.
The drainage pipe route must not rise above the siphon!
m
The condensation outlet must be made frost-proof!

Flange connection / connecting pieces

The KWL EC ... Pro / WW types are supplied with a flange connection as standard.

The piping must be firmly and tightly connected to the connection valves. Refer to the illustrations for the

arrangement of ventilation ducting.

The operation of the KWL unit in conjunction with an active cooling system, e.g. air conditioning system,
is not permissible!

Air ducting, Ventilation circuit

With regard to planning and design, use the shortest possible lines. Airtight connections and changeovers must be
ensured. To avoid pressure losses, dirt build-up and noise, use smooth ducts (plastic or rigid ducting). For main lines
(outside, outgoing air, supply air distributor, extract collector), DN (KWL EC 700 D = 250 mm; KWL EC 1400 D = 315
mm; KWL EC 2000 D = 400 mm) or corresponding ducting should be provided, and the ø is reduced accordingly for
branch lines.
Outside and outgoing air pipes are to be insulated in an appropriate way to reduce condensation. The minimum insu-
lating thicknesses pursuant to DIN EN 1946-6, 05/2009 are to be observed. If supply and extract air ductwork runs
through unheated rooms, insulation must be provided to reduce heat losses. Supply air should be supplied to primary
rooms and extraction should take place in secondary rooms. To balance the whole system, supply and extract air
openings should be provided with adjustable valves (accessories).
A filter (accessory) is to be connected for the extraction of polluted extract air. The installation of extractor hoods to the
system is not permitted (reasons: dirt, fire danger, hygiene). Sufficient overflow openings (door gap, door grilles) are to
be provided to ensure air circulation within the room.
