The appliance must be installed
in compliance with national
legislation in force in the country
of destination.
i
Before starting any work, safety
checks must be performed in
order to reduce any dangers to a
minimum. All staff in charge must
be aware of the operations and
any dangers that may occur when
all unit installation operations
begin.
4.1 INTERNAL HYDRAULIC
CIRCUIT (standard supply)
The VENICE is supplied as per
standard with the following hydraulic
components:
• Cooling only version (TAB. 01)
- ø 1" water filter for protection of the
circulator and evaporator
- Safety valve calibrated at 3 bar
- Circulator
- Flow meter
- Evaporator
- Condenser
- Storage
- Relief valve
• Heat pump version (TAB. 02)
- ø 1" water filter
One for protection of the circulator
and the evaporator
One for protection of the condenser
- Safety valve calibrated at 3 bar
- Circulator
- Flow meter
one after the circulator
one after the filter upstream from
the condenser
- Evaporator
- Condenser
- Storage
- Relief valve
4.2 EXTERNAL HYDRAULIC
CIRCUIT (recommended)
After having examined the internal
hydraulic circuit, we recommend
the installation of the following
components:
– high pressure flexible joints in order
to prevent the transmission of
vibrations to plant pipes;
– manual interception valves between
the unit and the rest of the plant,
in order to ease maintenance
operations and prevent discharge of
the entire plant;
– plant automatic feeder with
manometer
– expansion vessel
Before connection it is good practice
to allow the water to flow through the
pipes in order to eliminate any foreign
bodies that could jeopardise correct
functioning of the appliance.
NOTE
The hydraulic connection pipes must
be suitably dimensioned and always
gurantee a constant flow rate to the
evaporator.
