Montage – Location of KWL EC 500 Pro

• The unit is mounted indoors, in a place where temperature does not fall below +5 °C.
2
• If installed within not heated areas (e.g. cock loft) a sufficient isolation on all sides is to be
mounted outside at the unit. Otherwise condensate formation at the casing sides could
occur. The condensate drainage must be laid frost protected.
• The unit is to be mounted in a place where the sound pressure level coming through the
envelope is not acoustically disturbing (utility room, washroom, corridors, technical rooms,
stores, and in some cases rooms where people spend time).
• The unit is mounted on the wall using the wall mounting plate included in the delivery.
Lift the unit to the wall making sure that the hooks on the back side of the unit attach to
the mounting plate.
• The unit is splash protected (IP34), and can thus also be mounted in a damp room.
• NOTE: Remove the transportation lock (wingnut) in the extract duct.
• Before start-up, check the rubber aprons of the motors. They must be fitted correctly.
• NOTE: The unit has to be mounted level with the vertical and the horizontal. (indispensable
for a correctly condensat drain).

Duct connections

• The unit has four (diameter160) inner fittings equipped with rubber rings. Fix the ducts
steadily and tightly to the outlets. (NOTE! Unit models L/R). Implement insulation as defined in
the ventilation plan.
