Wilo-WiBooster - Installation and Operation Manual
CAUTION!
Risk of damage!
The equipment must be transported by means of
authorized load carriers. Stability of the load must be
ensured, since the pumps have been constructed in a way
that shifts their center of gravity to the top. Transport
straps or ropes must be secured to the existing transport
lugs or placed around the base frame. The pipes are not
designed to withstand loads and should not be used to
secure loads in transit.
CAUTION!
Risk of damage! The system must be protected against
moisture, frost and heat and also mechanical damage by
means of suitable measures!
Unpack. Carefully inspect the Wilo-WiBooster pressure
Boosting system or the accessory parts for possible damage
and notify the delivery company (forwarder) or Wilo after-
sales service. After removing the packing, store or install the
unit according to the installation conditions described (see
section entitled Installation). Concealed damage will not
be revealed until after start-up, at which time notify Wilo
after-sales service.
DANGER!
Risk of bodily harm or death! A storage tank, if used,
must be vented to atmosphere and unpressurized! Over-
pressurizing a storage tank can cause an explosion!

Applications
Pressure boosting systems are designed for boosting and
maintaining the pressure of water supply systems. They are
used as:
• Potable water supply systems
• High-rise apartments
• Hospitals
•
Offices
• Industrial buildings
The pressure boosting system’s structure, function and
requirements comply with the following guidelines and
directives:
• NSF 61 and NSF 372 listed for drinking water
certification
• DOE regulations
The Wilo-WiBooster pressure boosting system must be
connected directly to a water main, or indirectly to a storage
tank. These storage tanks are open to atmospheric pressure
and should never be pressurized.

Description of the product and accessories
5.1
General description
The Wilo-WiBooster pressure booster is a compact system
that is supplied completely piped and ready to connect. The
only connections that have to be made are for the inlet and
pressure pipes and the main power connection. It may also
be necessary to install accessories ordered separately but
included in the delivery.
5.2
Pump Venting
CAUTION! DO NOT RUN PUMPS DRY!
The Wilo-WiBooster presssure booster is supplied with 2-4
non-self-priming pumps that can be connected indirectly
(non-pressurized water storage tank) or directly to the
water supply main from the city. If pump is installed with
a positive head on the suction, prime by opening suction
valve and allowing liquid to enter the casing, at the same
time venting all air out of the top of the casing. If pump is
installed with a suction lift, priming must be done by other
methods, such as foot valves, ejectors, or by manually filling
casing and suction line. (See Fig. 5a).
