Danger due to vibration!
Regularly check the fixing of the unit to the support structure.
Excessive vibration of the unit can seriously damage the machine.
The vibration dampers are not included but are available on request.
NOTE FOR THE USER
•
The unit's support surface must be flat, sturdy,
stable and as level as possible.
•
The unit must be installed on a structure that does not transmit
vibrations. Do not install the unit on structures that can transmit or
amplify the noise.
•
Installation of the unit must always be done using vibration dampers.
•
Installation of the unit must ensure that motor ventilation is not
impeded by obstacles placed in the immediate vicinity. Therefore, the
motor air intake must remain free, ensuring a distance of at least
50mm (2 In) between the motor fan cover and any structure.
•
Connect the pipes using flexible sleeves, without resting the weight of
the pipes on the unit, with the exception of a possible filter in case of
suction in the place.
•
Determine the dimensions a, b, c to allow adequate space for
installation of the unit with its accessories (Dimensions available in the
first section).
When installed outdoors, protect the unit
ATTENTION!
against the sun and weather.
To avoid overloads caused by pressure fluctuations, install a bypass pressure-relief valve on the suction
pipe in case of operation as an exhauster, and on the delivery when operating as a blower.
If the flow rate has to be reduced, use a bypass valve instead of throttling the suction or delivery.
Protect the suction pipe with a filter with max. degree of filtration 25µm. For the use of filters with filtration
different from 25µm, ask FPZ. Foreign bodies are: dust, sand, gravel, dirt in the pipes, cutting burrs and
shavings, welding slag and spatter, metal burrs and sealant residuals produced when connecting the pipes.
Change the filters regularly.
Size the pipes and choose accessories that minimise pressure losses; therefore:
•
do not fit pipes narrower than the ports of the machine.
•
when installing several machines in parallel, suitably size the manifold and the main line.
•
use large-radius curves and not elbows.
•
do not install valves with a smaller flow than nominal and check valves with shutter opposed by spring (the check valve with
lowest pressure loss is the lightened non-return valve).
•
when used for oxygenation, choose diffusers with low flow resistance (low pressure loss).
Danger due to foreign bodies and dirt entering the unit!
The ingress of even tiny foreign bodies causes serious damage to the unit with probable breakage of the impeller blades and the danger
of debris being thrown out!
See INSTALLATION DIAGRAMS in the first section.
