3.2.5 - Desludging
We would advise you to fi t a settling tank (not supplied) on
underfl oor heating installations.
• The installation MUST be rinsed and
desludged before making the hydraulic
connection with the heat pump.
3.2.7 - Heating circuit
3.2.7.2 - Backfl ow prevention device
3.2.6 - Heat Pump water inlet fi lter (supplied)
A 1’’ valve with a built-in 500μm fi lter must be fi tted to the water
inlet piping on the Heat Pump:
• Respect the fl ow direction of the fi lter (arrow on the
valve)
• Install the 1’’ valve with fi lter on the inside of the
building and ensure it is thermally insulated
Clean the fi lter several times as soon as
the Heat Pump circulator pump has been
activated (take care to switch the circulator pump off
before cleaning).
• Clean the fi lter at least once a year.
For underfl oor heating installations, the
piping for the heating circuit must not be
under 1’’ in diametre.
3.2.7.1 - Heating circuit fl ow rate
• For heating circuits with radiators, fan coil units or underfl oor
heating:
The fl ow rate must be suffi
cient to ensure that the diff erence in
temperature between the leaving and return points is not over
15K in radiator or fan coil unit circuits or 7K in underfl oor heating
circuits.
For installations which have thermostatic valves, this test must
be carried out with all valves open.
The heating capacity from the heat radiating sources determines
the heating water fl ow rate and allows you to check that the
sections, lengths and layout of the hydraulic distribution
network are compatible with the Pilot circulator pump.
Adjust the speed (I, II, III, IV) of the UPM3 15-70 circulator pump
which is fi tted to the Pilot to the characteristics of the hydraulic
circuit using the curve chart at top of next column: fl ow rate Q
(m
3
/h) / pressure head H (mCE).
French law (articles 16.7 and 16.8 of the "Règlement Sanitaire
Départemental") stipulates that a type CB backfl ow prevention
device must be fi tted. This device must be at diff erent, non-
regulated pressure zones, in accordance with the NF P 43-011
standard. This is also an obligatory requirement in other countries
so it is important to check the current laws and standards in
the country of installation and ensure that your installation is
in compliance with them. The backfl ow prevention device is
designed to prevent incoming heating water from going into the
drinking water circuit. It must be connected to mains drainage.
3.2.7.4 - Insulating the piping
3.2.7.5 - Expansion vessel
3.2.7.6 - Frost protection and water
treatment
3.2.7.3 - Degassing the heating circuit
All necessary measures must be taken to ensure that the
installation can be continuously degassed. Automatic air valves
should be placed at each high point of the installation and
manual air valves should be fi tted on each radiator.
Insulants must comply with DTU 67.1 or the current regulations in
the country of installation.
All visible piping and accessories (circulator pump, expansion
vessel, valve, etc...) must be insulated
.
Remember to insulate the
distribution manifolds and the return and supply fl ow pipes to the
underfl oor heating circuit; remember to insulate
the piping which
connects the Heat Pump to the Pilot.
An expansion vessel needs to be fi tted onto the heating circuit.
