2.6 Assembling options / accessories
The ceiling is fitted with M8 inserts on each corner of the opening frame to accommodate external accessories: adapter pieces - insulated flexible
sleeves - rigid flexible sleeves - dampers. Each accessory is delivery with screws.
Protective foam should be installed between the accessories and opening frames to ensure an airtight junction between the elements.
Adapter pieces
2.6.1 Connecting adapter pieces
Adapter pieces are supplied with 4 screws, washers and M8 nuts. As necessary, screw each adapter piece into the in-
serts on the opening frames or on the insulation dampers, by assembling washer, screw and nut in each assembly corner.
To connect circular ducts, they must be fitted with a rubber O-ring seal. Refer to the diameters for each machine in section 3.3.
Insulate the ducts and adapter pieces in accordance with applicable standards and regulations.
2.6.2. Fitting an insulation damper on fresh air / discharged air duct
Dampers are supplied with pre-wired servo-motors, an RG link cable (whether one or two dampers are present), a junction box and M8 screws.
Fit an airtight seal on each opening frame. Screw each damper into the inserts on the opening frame.
Connect the RG cable to the RG1 - RG2 terminals on the terminal block (see diagram below), ensuring beforehand that the cable is passed through the
cable gland on the electrical box, to ensure the IPX2 rating. For technical data concerning the terminals, refer to section 2.8.2.
