FLEXIBLE AIR PIPE PART
Put a flexible part between the blower and the piping in both the suction and pressure connectors. This prevents
possible vibrations from passing on to the piping or heavy loads created in the piping from passing on to the blower
unit. So the piping must be supported and the flexible part must not be subjected to any excess load resulting from
the weight of the piping.
INSTALLATION
The blower unit is heavy and because of possible vibrations resulting from its unbalance, it must be placed on a
firm base. The blower unit must always be attached to its base using bolts.
The air amount adjuster of a radial blower can be located either between the dryer and the blower or in the pipe
on the pressure-side of the blower.
NOTE! The adjuster must never be located in the pipe between the heater and the dryer.
The blower delivery also includes a protective net which must be removed before connecting a pipe either before
or after the blower. Any net installed will gather dirt and you must be able to clean it regularly.
