Topping up the system pressure

External filling loop
Once the external filling loop and the external pressure gauge have been
located, follow the instructions for re-pressurising the system.
▶ Unscrew the blanking cap [1].
▶ Attach the hose [2] to the valve.
– Usually one end of the hose is already connected to one of the
system fill isolation valves.
▶ Ensure both ends [3] of the hose are screwed on hand tight.
▶ Monitor the pressure via the external pressure gauge.
– The system fill isolation valves [4] are in a closed position (the
handle/screwdriver slot is across the valve).
▶ Turn the handle/screwdriver slot through 90° to open valves and
slowly fill the system.
– The system fill isolation valves [5] are opened (the handle/
screwdriver slot is in-line with the valve).
– The pressure at the display will start to rise.
▶ Set the pressure between 1 and 1.5 bar pressure.
▶ Turn the handles/screwdriver slots back, through 90°, to close the
valves.
– The system fill isolation valves [6] are in a closed position (the
handle/screwdriver slot is across the valve).
▶ Top up the system pressure, if as a result of the air bleeding the
pressure drops off.
Once the pressure has settled between 1 and 1.5 bar.
▶ Ensure the valves are closed.
▶ Remove the hose [2] and replace the blanking cap [1].
