
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.

The unit must always be installed using vibration dampers, with tightening torque 3.0Nm.

Connect the pipes using flexible sleeves, without resting the weight of the pipes on the unit, with the exception of a possible
filter supplied by FPZ in case of suction in the place.

Establish the dimensions A, B, C to allow adequate space for installation of the unit with relevant accessories (Dimensions
given on the data sheet).
ATTENTION Ensure ventilation of the machine so that the surrounding environment is less than or equal to 40°C
Danger due to limited visibility in the place where the unit is installed.
Make sure to always have the installed unit under control when carrying out any operation in the installation area.
The control elements must be placed so that the installed unit can be seen.
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.
NOTE FOR THE
Vibration dampers are supplied with GOR / MOR machines
USER
If installed outdoors, protect the unit against the sun and weather.
ATTENTION
Also the motor ventilation must not be hindered by obstacles placed in the immediate vicinity.
When using the blower to convey biogas, natural gas or similar, the unit must be installed outdoors or in air change conditions so that
any gas leaks are dispersed; conditions able to cause the accumulation of gas pockets must not occur.
Depending on the type of installation, provide for:

a bypass relief device according EN 126 on the suction pipe in case of operation as an exhauster, and on the delivery when
operating as a blower, to avoid overloads caused by pressure fluctuations;

a flow control and variation device (Q) by means of a bypass valve or equivalent system

a filter or filtration system for the conveyed fluid with degree of filtration 20 µm / 25 µm.
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 bore smaller than nominal and check valves with shutter opposed by spring

clean the pipes thoroughly before connection.
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!
