INSTALLATION OF THE ACCESSORIES
A 90° plenum (RAM) may be used instead of the air delivery union for better direction of airflow.
Insert the manual air intake section (SSP) in the air filter section (SFA) by means of the male-female coupling.
After having secured it with the self-tapping screws (4.2 x 9.5 galvanised), anchor it to the ceiling as illustrated for the
base unit in figures 4-7.
Put another connecting flange on the vibration isolation joint (GAM) and secure it using cheese-headed screws M8x16
and hexagon bolts.Insert the straight delivery plenum (PAM) in the connecting flange and fix it using galvanised self-
tapping screws 4.2 x 9.5.
Then connect the 90° plenum (RAM) with the procedure described above.

The heating section with electric heating element (SRE) is usually placed on the delivery side before the straight delivery
plenum (PAM).
It may be used either with the delivery union (BAM) or with the 90° delivery plenum (RAM).
The coupling is of the male-female type with fixing by means of galvanised self-tapping screws 4.2 X 9.5
