HYDRAULIC SYSTEM

Components
Selection and installation of system
components must be carry out by
installer.
Water quality
The water quality is determined by the
following factors, avoid therefore:
- Inorganic salts
- pH
- Biological load (seaweeds etc)
- Suspended solids
- Dissolved oxygen
Water with inadequate characteristics
can cause:
- pressure drop increase
- energy efficiency decrease
- corrosive symptom increase
Risk of freeze
If the unit or the relative water
connections can be subject to
temperatures close to 0°C adopt
measures for prevent risk of freeze.
The appliance is intended to be
permanently connected to the water
mains and not connected by a hose-set .
The water may drip from the discharge
pipe of the pressure-relief device and
that this pipe must be left open to the
atmosphere.
The pressure-relief device is to be
operated regularly to remove lime
deposits and to verify that is not blocked.
A discharge pipe connected to the
pressure-relief device is to be installed in
a continuously downward direction and
in a frost-free environment.

Power supply circuit should be earthed
effectively.
Do not use water pipes to earthing
connection of the unit
Use single protection devices : gloves,
glasses ecc.

cable section must be defined in
accordance with the characteristics of the
protections adopted. The serial number
label reports the unit specific electrical
data, included any electrical accessories.
