dents and deformation. The impeller must not be in contact with the exhaust spigot and
the casing during rotation.
Observe general and specific safety precautions during the fan set-up.
Safe grounding of the fan must be provided. The circuit breaker installation place must ensure
free access for quick shutdown of the fan.
The fan is attached to the floor by means of the mounting brackets or suspended to a horizontal
even surface by means of eye bolts.
The fan mounting options are shown in Fig. 7-18. While installing the fan ensure convenient
access for subsequent maintenance and repair. To attain the best performance of the fan
and to minimize turbulence-induced air pressure losses connect a straight air duct section
to the fan spigots on both sides of the fan. The minimum straight air duct length is equal
to 1 air duct diameter on the intake side and 3 air duct diameters on the exhaust side.
No filters or any other similar devices are allowed to be installed in these sections.
Installation of rubber anti-vibration mounts is recommended for vibration absorption.
The air flow direction in the system must match the arrowhead on the fan casing.
Be sure to set the required impeller speed and temperature setpoint by turning the respective
control knobs for the models equipped with the temperature and speed controller module.
The set temperature range is +20 °C up to +30 °C.
Do not install the fan on a flammable material. Vertical fixation of the fan to the wall
