Condair UDC - Mounting Location; Installation; Product Specifications

38 Condair CRC and CRC-NA
3.4 Mounting location
The Condair CRC or CRC-NA is mounted at least 1.5 m above the oor directly to the wall.
Observe the following placement notes:
– Do not place the Condair CRC or CRC-NA in niches, behind curtains, etc.
– Do not place the Condair CRC or CRC-NA near heat sources, within the area with direct air draft or
direct sunlight.
3.5 Installation
1. Open the screw of the housing and remove mounting plate.
2. At the place of location x mounting plate (plastic screw facing downwards) with two screws (see
dimensional drawing).
3. Lead connecting cable from the bottom into the housing and connect wires to the terminals accord-
ing to the wiring diagram.
4. Snap housing onto the mounting plate, and x it with the screw (do not tighten screw too much).
