INSTALLATION ON A ROOF MOUNTING FRAME ASSEMBLY The frame is supplied as a single package and shipped folded down for ease of transport and handling. It is easy field assembled as all parts required are supplied with the frame. SECURING THE FRAME To ensure proper mating with units (figure 7), it is mandatory that the roof mounting frame be squared to roof structure as follows: -With frame positioned levelled in the desired location on roof trusses, tack weld corner of frame.
INSTALLATION ON A ROOF MOUNTING FRAME When the frame is correctly positioned. It is essential to secure the assembly with a disconnected stitched welded seam (20 to 30mm every 200mm ) along the outside or by using an alternative method.

VENTILATION BELT TENSION BELT TENSION On delivery, the drive belts are new and correctly tensioned. After the first 50 operating hours check and adjust the tension. 80% of the total elongation of belts is generally produced during the first 15 hours of operation. Before adjusting the tension, make sure that the pulleys are correctly aligned.
