ROOF CURB DIMENSIONS

The frame of the curb receiving the unit must be leveled. The unit must slot perfectly into the roof curb.
POSITIONING OF THE ROOF CURB ON THE ROOF (CUTAWAY VIEW)
1. Roof curb
2. Rubber seal (supplied with the roof curb)
3. Hard vibration-absorbent rubber (option)
4. Concrete beam or slab
5. Vapour sealing film (supplied by the roofer)
6. Roof insulation (supplied by the roofer)
7. Sealant roofskin (supplied by the roofer)
In order to break a thermal bridge between the roof curb and the unit, a seal (N°2) (50 X 5 mm) is
supplied with the roof curb. This seal must be glued by the installer on the roof curb to avoid metal
to metal contact and reduce eventual vibration transfer.
Once installed and fastened to the roof structure, the outside wall of the curb must be fully integrated in the roof
insulation.
To insulate the Roof curb before posing to ROOFT@IR it.
The minimum insulation thickness required is 25 mm and the surface must be protected by a bituminous coating
(or any other equivalent material) to ensure a perfect weatherproof seal.

CONFIGURATION OF THE UNIT

GENERALITIES

The unit is designed to be connected to a duct work. Should it not be the case, a discharge protection grille and
a device creating sufficient pressure drop must be supplied by the installer to avoid excess current draw generated
at the motor (see blower curves in the appendix)
4 discharges and 4 intakes air configurations are available.
For each configuration, note the dimensions of the discharge air duct to be provided before the unit arrives on site.
Make sure that it is fireproof and that it does produce toxic smoke in the event of a fire in the building. The interior
surfaces must be smooth and cleanable to avoid contamination of the circulated air.
NEVER DRILL ANY HOLES IN THE AIR TREATMENT ZONE OF THE UNIT. THE
MANUFACTURER'S WARRANTY WILL BE CANCELLED IN THE EVENT OF ANY
WATER LEAKS RESULTING FROM THE DRILLING OF HOLES IN THE CASING.
