Installation

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
hydronic module.
• Use pipe 1" or bigger for connections between the
hydronic module and terminal.
Refrigerant connections
Please refer to the Safety Information manual.
For piping lengths, refer to the outdoor unit manual.

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 the
system at different pump speed (see fig 13 and fig. 14) and
the pressure drop of the installation.
Make sure the pressure drop in the domestic hot water loop
is not too low; if needed install a valve to modulate pressure
drop; in this loop, inlet / outlet temperature difference
should be 8 – 10 °C.

• 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.
Maximum distance between 3 way valve and hydronic
