Installation

Mechanical installation

Please refer to the Safety information manual.
See fig.5.
1. Remove side panels from hydronic module and 2 zone
kit
2. Insert the provided screws at the bottom of the hydronic
module (see fig.5.a); leave a gap between the head of
the screw and the metal bracket
3. Position the 2 zone kit so that the screws enter in the
slots (fig. 5.b)

Water connections

Please refer to the Safety Information manual.
A counter spanner is not needed when tightening
hydronic connections to the module.
To avoid bacteria and dirt proliferation in the circuit, use
water treatment mixed water.
Place valves (not included) at the inlet and outlet of the
2 zone kit
Use pipe 1" or bigger for connections between the 2 zone
kit and terminal.

Pump speed selection

The pump provided with the module has 3 speeds.
The installer selects the speed of the module pump in order
to guarantee the target flow rate (± 20 %) in the space
heating /cooling loop, knowing the available pressure of

space A).
Wrap connections with anti-condensate insulation and
tighten with tape, without exerting excessive pressure on
the insulation.
When all the installation connections are complete, start
water filling.
