IMPORTANT - when filling:
When filling there may be a slight water leak from the air vent therefore electrical connections should be protected.
Filling
1. Ensure filling loop is connected and all washers in place.
2. Ensure dust cap on auto air vent is slackened off. Refer to
Section 3.24.
3. Check the following isolation handles on water connections
are in the horizontal filling position (blue handle on DHW
inlet
A
and black handle on CH return
C
).
Note
. The CH flow isolation valve handle MUST be in the
vertical position to enable filling.
4. Slowly turn the filling loop handle (blue
B
) to the
horizontal open position until the pressure gauge reads
between 1 to 1.5 bar.
5. Once the pressure gauge dial reads between 1 to1.5 bar
turn the filling loop handle (blue
B
) back to the closed
(vertical) position.
6. Turn the CH Return handle (black
C
) and the DHW Inlet
handle (blue
A
) to the open (vertical) position.
7. Disconnect the filling loop from the DHW Inlet valve and fit
the grey cap to the open end.
8. Fit the Plug to the free end of the filling loop.
Note. Open all DHW taps to ensure water is flowing freely.
Once satisfied close all taps.
