6.2 EXTERNAL FILLING LOOP
Locate the external filling loop and follow the instructions for re-pressurising.
Ensure that the isolating valves are shut before removing the blanking caps. The
valves are shut when the handle or screwdriver slot is at 90° to the valve.
1. Unscrew the blanking cap(s) from the isolating valves.
2. Attach the filling loop and screw on, hand-tight, to both isolating valve.
3. The handle/screwdriver slot has only to be turned through 90° (¼ turn) to open
the valve.
4. The handle/screwdriver slot will then be in-line with the valve, i.e. vertical.
FILLING PROCEDURE:
Open one of the valves, do not turn passed 90° i.e. ¼ turn.
Monitor the water pressure gauge and slowly open the second valve until water
can be heard flowing and the pressure gauge starts to rise.
When the water pressure reaches 1 to 1.5 bar, close the valve, this will stop the
system filling.
Once the system has been re-pressurised, to the correct pressure, close the
other valve.
Ensure both valves are closed before removing the hose.
Remove the hose and replace the blanking cap(s).
NOTICE: If the filling loop does not look like the one shown in the
figure below or you cannot find your filling loop, contact your
installer.
