4 Intended use

The Wilo pressure-boosting systems of series
ISAR MODH1 are designed for water supply sys-
tems for pressure boosting and pressure mainte-
nance.
They are used in:
• Drinking water installations, primarily in high-rise
apartments, hospitals, administrative and industrial
buildings, the structure, function and requirements
of which comply with the following
standards, guidelines and directives:
• Water Supply (Water Quality) Regulations 2018
Reg 4
• Industrial water supply and cooling systems
• Irrigation and sprinkling installations
Make sure that the fluid to be pumped in the
system will not corrode the materials used in the
system either chemically or mechanically and that
it does not contain any abrasive or long-fibre
constituents.
Automatically controlled pressure-boosting sys-
tems are supplied from the public drinking water
supply network (connected indirectly) via a break
tank. These break tanks are closed but are not
pressurised, i.e. they are under only atmospheric
pressure.
