For the Installer
The heating medium system is filled with water until
the required pressure is reached and then vented.
To fill the collector system, mix about 30% antifreeze
with water in an open container and connect with fill-
ing pump and hoses as illustrated. Close the valve on
the main pipe between the service connections and fill
through the connection under the level vessel (NK)
(which has been removed) until the fluid emerges from
the return hose. Then make the following settings on
the control panel.
■ Set the switch to 1.
■ Go to the Brine-pump menu, Add-driftin the ser-
vice menu. Set the Brine-pump to 1 and press
Operating mode. Set Add-drift to 1 and press
Operating mode
Before starting up the system, check that the heating,
collector and hot water circuits are full and thoroughly
vented. Check the pipe system for leaks.

Operating mode button
The heat pump cannot start as the operating mode EB
(electric boiler mode only) is selected. The brine pump
is now operational together with the filling pump. The
fluid can circulate via the mixing vessel until fluid, with-
out air, returns to the return hose. Now stop the brine
pump by setting Brine-pump to “0”.
Stop the filling pump and clean the particle filter. Then
start the filling pump again. Open the valve on the
main pipe between the service branches while the fill-
ing pump is still operational (to release the air
between the branches). Now close the valve by the
return hose. Pressurise the system (to max 3 bar) with
the filling pump. Close the valve where the level ves-
sel is fitted and stop the filler pump.
Remove the filler hoses and refit the level vessel. Fill
the vessel about three-quarters full with the fluid. Now
shut the filling plug and open the valve under the ves-
sel. Reset normal mode by setting EB to “0”.
