7. Installation
Before installation, check the following:
• Does the booster system correspond to order?
• Are all visible parts intact?
7.1 Mechanical installation
7.1.1 Location
The booster system must be installed in a well ventilated room to
ensure sufficient cooling of the pumps and the control cabinet.
The booster system must have a 1-metre clearance on all sides
for inspection and dismantling.
7.1.2 Pipework
Connect the pipes to the manifolds of the booster system.
Either end can be used. Apply sealing compound to the unused
end of the manifold, and fit the screw cap. For manifolds with
flanges, fit a blanking flange with gasket.
We recommend that you install pipe supports for the suction and
discharge pipes. See fig.
and fig.
.
To achieve optimum operation and minimise noise and vibration,
it may be necessary to consider vibration dampening of the
booster system.
Noise and vibration are generated by the rotations in the motor
and pump and by the flow in pipework and fittings. The effect on
the environment is subjective and depends on correct installation
and the state of the other parts of the system.
If booster systems are installed in blocks of flats or the first
consumer on the line is close to the booster system, we
recommend that you fit expansion joints on the suction and
discharge pipes to prevent vibration being transmitted through
the pipework.

All nuts should be re-tightened prior to startup.
The pipes must be fastened to parts of the building to ensure that
they cannot move or be twisted.
7.1.3 Foundation
The booster system should be positioned on an even and solid
surface, for instance a concrete floor or foundation. The booster
system must be bolted to the floor or foundation.
7.1.4 Vibration dampers
To prevent the transmission of vibrations to buildings, we
recommend that you isolate the booster system foundation from
building parts by means of vibration dampers.
Which is the right damper varies from installation to installation,
and a wrong damper may increase the vibration level.
Vibration dampers should therefore be sized by the supplier of
vibration dampers. If the booster system is installed on a base
frame with vibration dampers, expansion joints should always be
fitted on the manifolds. This is important to prevent the booster
system from "hanging" in the pipework.
Warning
Installation and operation must comply with local
regulations and accepted codes of good practice.
Caution
The booster system is not designed for outdoor
installation and must not be exposed to direct
sunlight.
Note
The pipework connected to the booster system
must be of adequate size.

Note
Expansion joints, pipe supports and mounting
bolts shown in fig.
and fig.
above are not
supplied with a standard booster system.
Note
As a rule of thumb, the weight of a concrete
foundation should be 1.5 x the weight of the
booster system.
