INSTALLATION
4.2 Mounting
i
Install the Systempro control unit near the hydraulic
module to facilitate system commissioning.
• Consult the corresponding installation manual and install the
following elements:
- the heat pump,
- the hydraulic module,
- the Systempro control unit,
- the Climapro2 wireless room thermostat,
- the wireless outdoor sensor.
5 Hydraulic connection
• Take care to clean the pipes before assembly removing any
debris or burrs. Grease and oils may need to be removed
they are not possible to remove by cleansing and fl ushing.
Foreign bodies in the system may enter the appliance and
interrupt its operation.
• Do not use any solvent products, due to the risk of damaging
the circuit.
• Only use original seals supplied with the appliance.
• Check that there are no leaks. Repair if necessary.
5.1 Heat pump circuit
• Comply with the values given in the table below when
making the hydraulic connections of the heat pump circuit.
Linear distance (without elbows or
additional pressure drops)
Min. diameter of tubes to
be installed
≤ 20 m Ø ¾"
≤ 30 m Ø 1"
b
In the case of an installation with the domestic
hot water tank option, deduce the pressure drop
of the 3-way valve with respect to the max. linear
distance allowed between the domestic hot water
tank and the PAC + between the PAC and the
hydraulic module (see chapter "Connection of an
exchanger tank for domestic hot water").
5.1.1 Connection to the heat pump
b
Insulate the pipes with an UV- and high-
temperature-resistant insulation.
