External filling loop (sealed system only)
This appliance is fitted to a sealed heating system which is pressurised. Your installer will advise you of the minimum and maximum
pressure indicated on the pressure gauge.
▶ Check regularly that the pressure is maintained.
▶ If the pressure gauge reads less than 1 bar then the system requires re-charging.
▶ Contact your installer or maintenance engineer if a permanent significant decrease or increase in pressure is indicated on the
pressure gauge.
Once the external filling loop has been located, follow the instructions for re-pressurising the system.
1. Unscrew blanking cap.
2. Attach the hose to the valves, screw on hand-tight.
3. Turn the handle/screwdriver slot through 90° to open the valves.
4. The handle/screwdriver slot will be in-line with the valves

5. When the pressure reaches between the 1 and 1.5 bar marks (zone A), turn the handle/screwdriver slot back, through 90°, to
close the valve.
6. The handle/screwdriver slot will be at 90° to the valves
7. Remove the hose and replace the blanking caps.
If the pressure gauge reads more than 1.5 bar as a result of over filling, bleed one radiator until the pressure gauge returns to
between 1 and 1.5 bar.
