Final installation of ventilation unit

Powerbox H

The Powerbox H is delivered ready for connection and inserted into the already installed WS 75 RSAP/RSUP shell unit, electrically wired and covered with the matching WS 75 APA/UPA/UPGA front cover.

Flush-mounted variant: If the installation position is rotated by 90°, the design cover of the flush-mounted variant still needs to have the stops and the locking mechanism modified.

Powerbox S

The Powerbox S is a complete unit without shell unit and design cover. For direct installation on a wall (usually an interior wall) or ceiling. Cladding provided by the customer. Free access required for servicing/maintenance.

The unit must be freely accessible for servicing/maintenance. Any cladding need can be fitted on site.

RLS G1 WS touch operating unit

The operating unit supplied is fitted with 2 magnets and is inserted into a bracket on the housing cover of the Powerbox H (sheet metal for accommodating control unit included in the scope of delivery of the design/glass cover).

Alternatively, an external installation of the RLS G1 WS on a flush-mounted electrical box is possible. The recess in the design/glass cover then has to be sealed with the optional RLS G1 V sealing kit.
