circuit
Unscrew the screw cover in the middle of the circula-

Bleeding the domestic hot water tank
To bleed the domestic hot water tank, the domestic hot
water charge circuit must be flushed separately.
To do this, manually switch the domestic hot water
changeover valve to domestic hot water charging.
After bleeding, return it to the initial position.
NOTE
Once the heat pump, heating circuit and
domestic hot water charging circuit have been
flushed, the bleeding program of the heating

after the control panel has been installed.
If no further steps follow, install the front panel.
