Aquarea air/water heat pump – Installation manual for monobloc and split systems C, D and E series 05 / 2014
Installation of heating and refrigeration circuits for split systems
Connecting the water pipes to the hydro module
➤
Fill the system as follows:
➤
Open all thermostatic radiator valves of the heating system, and all
other shutoff valves where applicable .
➤
Connect a filling hose (evacuated if possible) to the system .
➤
Keep adding water or antifreeze mix until the manometer reaches
the nominal pressure .
➤
Vent the system (see the Commissioning section (9)) . Then check the
pressure again and add liquid if necessary

Manometer
Warning!
There must be at least 50 litres (for 12 to 16 kW devices) or 30 litres
(for 3 .0 to 9 .0 kW single fan deck) of liquid in the system .
If these values are not reached, an additional storage tank must be
installed .
Warning!
To prevent damage to the heat pump from lime scale, please consult
BS 7593 “Code of practice for treatment of water in domestic hot water
central heating systems” .

Note
The hydro modules feature an
expansion tank as standard
(approx . 10 litres of air capacity,
initial pressure of 1 bar) . The
water quantity in the system
should be less than 200 litres
(without a hot-water tank),
otherwise an expansion tank
must be included . There are
roughly 5 litres in the hydro
module . The height difference in
the water circuit should not ex-
ceed 7 metres . See the design
handbook for split systems and
monobloc systems for other
connection variants .
