MOUNTING AND SET-UP
The unit may be suspended on threaded rods or may be rigidly fixed to a horizontal surface by anchor bolts.
Fasteners for fan mounting should be ordered separately.
While choosing fasteners consider the material of the mounting surface as well as the weigh of the unit, refer to the “Technical data”
section.
Fasteners for unit mounting should be selected by the service technician.

Make sure that the installation site is capable of sustaining the unit weight.
Otherwise reinforce the mounting location with beams or similar elements.
If the bolts used for the unit mounting are too short the unit can generate abnormal noise and resonate with the ceiling.
Use bolts of sufficient length to prevent resonance.
If the noise is generated at the spiral air duct joint, replace the spiral air duct with a flexible one to prevent resonance.
Flexible anti-vibration connectors are another alternative for dealing with resonance.
Push the air ducts onto the flanges of the unit until stop.
Flexible ducts must be fixed rigidly with a metal worming clamp.
WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT
MAINTENANCE AND REPAIR.
BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN
OBJECTS (E.G. FOIL, PAPER).
