•
Install the blower with an inclination of at least 1%, on the motor
side, to allow the condensate to drain through the special outlet.
•
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 with the
use of vibration dampers, and four M8 screws with tightening
torque 3.0Nm – 3.5Nm.
•
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.
•
Establish the dimensions A, B, C to allow adequate space for
installation of the unit with accessories (Dimensions given on
the data sheet).
When using the blower for conveying 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.
ATTENTION
When installed outdoors, protect the unit against the sun and weather.
Also the motor ventilation must not be impeded by obstacles placed in the immediate vicinity.
The blower is arranged for the installation of control systems. The following must be provided for by the installer to prevent machine
faults that can produce potential sources of triggering:
•
Pressure sensor (see §5.3 F)
•
Temperature sensor (see §5.3 G)
Depending on the type of installation (i.e. diagram §.5.3) 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 max filtration 25 µm (see § 3.3).
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)
•
clean the pipes thoroughly before connection.
See INSTALLATION DIAGRAMS in the first section
12.2
BLOWER INSTALLATION
Operations to be performed for installation of the blower:
1.
Fix the base and unit's vibration dampers to the system structure.
2.
Tighten the screws. 4 screws M8 (3.0 – 3.5 Nm)
3.
Remove the protection from the manifolds.
4.
Use flexible sleeves to connect the unit to the system.
5.
Check the motor rotation direction.
6.
Connect the pipes permanently.
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!
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!
