General description

The Wilo ISAR pressure-boosting system is sup-
plied ready for connection as a compact unit with
built-in controls. It consists of 1 to 3 non selfprim-
ing multistage horizontal centrifugal pumps which
are supplied completely piped to each other and
mounted on a common base frame. The con-
nections for the inlet and pressure pipes and the
electrical mains and earthing connection have to
be established. It is also necessary to install the
supplied accessories ordered separately.
The pressure-boosting system with non self-
priming pumps can be connected indirectly to
the water supply mains via a break tank. Detailed
instructions for the pump type used can be found
in the attached installation and operating instruc-
tions for the pump.
Observe the relevant, applicable regulations and
standards when using the system for drinking
water supply. The system must be operated and
maintained in accordance with the relevant
instructions so that the operational reliability
of the water supply is permanently guaranteed
and neither the public water supply nor other
consumption installations are detrimentally
affected. The respective applicable regulations or
standards on the connection and type of connec-
tion to public water supply networks are to be ob-
served. They may be supplemented by regulations
of the water supply companies or the responsible
fire protection authority. In addition, the local con-
ditions must also be observed.
