The heating circuit (boiler and tank exchanger) must be filled using
the drainage tap to the rear of the tank. When filling the heating
circuit, correctly bleed the exchanger on the domestic water calorifier
as follows::
Unscrew the cap on the automatic bleed valve by a few turns.
Ensure that the non-return angle valve is in the automatic
position (A).
Fill the installation with water. Close the cap on the automatic
bleeder valve when water flows out.
After filling the installation, close the drainage tap.
Unstick the load pump in necessary: to do this, unscrew the
protection cap in front of the pump and insert a screwdriver into the
slit (V) on the pump center line. Turn several times to the right and
left. Cold run the pump for a few minutes to enable priming. The
heating circuit will be bled by the automatic bleed valve delivered with
the appliance at the highest point of the installation.
