1 Drain, brine side
f Remove the sealing panel.
f
Fill the brine circuit via the drain.
f
Vent the brine circuit.
Check the brine concentration
f Determine the density of the glycol/water mixture, e.g. with
a hydrometer.
Using the actual density and temperature, you can check the actual
concentration in the diagram.
Note
The quoted output data relates to ethylene glycol (see
"Specification").

9.5 Heating water connection
Note
The use of non-return valves in the charging circuits be-
tween the heat generator and the buffer or DHW cylin-
der can impair the function of the integral multifunction
assembly (MFG) and lead to faults in the heating system.
f
Only use our standard hydraulic solutions for the
installation of the appliances.
The heating system to which the heat pump is connected must be
installed by a qualified contractor in accordance with the water
installation diagrams that are part of the technical guides.
f Thoroughly flush the pipework before connecting the heat
pump. Foreign bodies, such as rust, sand and sealant, can
impair the operational reliability of the heat pump. We rec-
ommend installing our filter assembly in the heating return
(see chapter "Appliance description / Accessories").
To facilitate easy connection to the heating system, the appliance
is supplied with push-fit connectors (see chapter "Installation /
Fitting push-fit connectors").
f Connect one flexible pressure hose each to act as an anti-vi-
bration mount to the "heating flow" and "heating return"
connections. The pressure hoses are part of the standard
delivery.
f Ensure that the heating flow and return are connected cor-
rectly.
f
Check for tightness.
f When sizing the heating circuit, observe the maximum avail-
able external pressure differential (see chapter "Specifica-
tion / Data table").
f Provide thermal insulation in accordance with applicable
regulations.
