1. GENERAL
Read this documentation carefully
before installation. It contains
fundamental instructions to be
followed during installation,
operation and maintenance.
Installation and functioning must comply with the
safety regulations in force in the country in which the
product is installed. The entire operation must be
carried out in a workmanlike manner, exclusively by
skilled personnel, in possession of the technical
qualifications indicated by the standards in force.
Failure to comply with the safety regulations not only
causes risk to personal safety and damage to the
equipment, but invalidates every right to assistance
under guarantee.
2. APPLICATIONS
Pumps for circulating hot and cold water, with
apertures in line for installations in series with plant
pipes. Suitable for civil and industrial heating,
conditioning and chilling plants and for domestic hot
water systems.
3. PUMPED FLUIDS
The machine has been designed and built for pumping
water, free from explosive substances and solid
particles or fibres, with a density of 1000 kg/m³ and a
kinematic viscosity of 1 mm²/s, and chemically non-
aggressive liquids. Use with other fluids is allowed only
with the manufacturer’s authorization.
