the stopcock (see Figure 2 on page 7). Connect a hosepipe to the drain cock (see Figure 2 on page 7) and route
EN
it to a convenient gully. Open the drain cock and all hot taps that are served by the cylinder. The cylinder may
take several minutes to empty completely.
The magnesium anode must be checked at least once a year, and must be replaced if worn or defective.
Remove the cartridge from the pressure reducing valve. Check the strainer and if necessary remove any
debris from in front of it. Replace the cartridge.
Check the charge pressure in the expansion vessel and top up as necessary. The charge pressure should be
0.15 or 0.3 MPa.
Close the drain cock, disconnect the hose, refi t the heating element and close all hot water taps before
reopening the stopcock. Allow the cylinder time to fi ll whilst checking for any leaks. Release any air from the
system by opening each hot water tap individually, starting with the one furthest from the cylinder.
Manually lift the expansion relief and temperature and pressure relief valve one at a time, every 12 months
(more frequently in hard water areas) to prevent debris from building up behind the valve seat. Whilst carrying
out this operation, check that the discharge to waste is unobstructed. Check that each valve seals correctly
when released. As the valves are pre-calibrated, they require no further maintenance.
Finally, when the product is full of water switch on the mains electricity supply to the product. As the system
heats up, check again for any leaks and rectify as necessary.
In the event of the manual reset cut-out operating, isolate the product from the mains supply, investigate and
identify the cause of the operation of this cut-out, rectify the fault before manually resetting the cut-out via
the reset button on the cut-out. Finally switch the mains electricity supply back on.
