4. Application
The booster is designed for boosting and main-
taining the pressure when the water supply net-
work is not well dimensioned or does not exist.
It is used for water supply in high-rise apart-
ments, hospitals, offices and industrial buildings.
Non aggressive clear fluids (potable water, water
containing glycol...).
A control box is used to control, monitor and
protect the boosting system.
The booster is either supplied from the public
water mains or from a mains collection tank.
In case of pressure deviations more than 1 bar in
the suction pipe it is recommended to use a pres-
sure relief valve. The pressure downstream of the
pressure relief valve (back-pressure) is the basis
for the total head calculation of the booster.

6. Description and operation
6.1 General description
The booster is a compact installation that is sup-
plied completely piped-up and ready to connect.
The only connections that have to be made are
for suction and delivery pipe and also the power
mains.
Every accessory ordered is delivery separately.
The relevant instructions or standards must be
observed for the connection to the public water
supply mains. Regulations from the water com-
panies must be included when appropriate. Local
conditions (e.g. a supply pressure that is too high
or fluctuates considerably and which might
require the installation of a pressure relief valve)
must also be observed.
