Optional integral keyed filling link
Locate filling key and follow instructions for re-pressurising.
1. Push the filling key firmly into the body of the filling link, ensuring the arrow on the key shaft lines up with the open padlock
symbol.
2. Turn the filling key to the right, to the stop, ensure the key is locked and that it cannot still turn. The arrow should line up with
the closed padlock symbol. This bridges the gap between the two sections of the filling loop.
3. Turn the white knob to the left, this will allow water to fill the system.
4. When the pressure, shown on the boiler fascia pressure gauge, reaches between the 1 and 1.5 bar marks (zone A), turn the
white knob to the right to close the valve. Do not overtighten.
5. Turn the filling key to the left, to the stop, so that the arrow lines up with the open padlock symbol and pull the key straight down
to remove. Please remember to store the key in the bottom panel.
