UNIT LOCATION

1. It must be high enough above the roof or ground to permit snow allowance and good drainage of
water with siphon.
2. Keep duct connections outside the building to a minimum to reduce energy losses.
3. In addition to the service clearances noted above it is essential that provision is made for adequate
and safe service access to the appliance.

ATTACHMENT TO THE GROUND

CONDENSATE DRAIN PAN

Ø 30
L = 30mm
The installer must imperatively supply a siphon.
CAUTION
For Heatpump models, where the outdoor temperature is likely to fall
below +1°C, provide a system to prevent the siphon from freezing (e.g.
heating cord).

ROOF CURB

The main purpose of the roof curb is to provide weatherproof passage,
supply and return air down to the building from the ROOFT@IR.
In this way, all connections (air, electricity) to the building are not free
above the roof. The curb provides a perfect roofing thermal insulation
and weight distribution between the ROOFT@IR and the building.
The roof curb should be used for a downward configuration at supply
and return air. The roof curb guarantees the perfect weathertight sealing
between the building structure and the appliance.
Two versions are available:
² knocked-down and non-adjustable version
This fixed roof curb, as an option, is supplied in kit form. Ask your sales representative.
² An adjustable version is available assembled at the factory with a return air grille (see below).
