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.
Please refer to the Safety Information manual.
For piping lengths, refer to the outdoor unit manual.
The pump provided with the module has 3 speeds.
The installer selects the speed of the module pump in order
to guarantee the target ow rate (± 20 %) in the space
heating /cooling loop, knowing the available pressure of the
system at dierent pump speed (see g 13 and g. 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 dierence
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 lling.
Maximum distance between 3 way valve and hydronic
module : 3m.
Maximum distance between domestic hot water tank and
hydronic module: 10 m.
