closes after testing);
4) Expansion relief valve - check manually by turning the test knob (ensure
valve closes after testing);
5) Discharge pipes (D1) - from both temperature & pressure relief and
expansion relief valve for obstructions;
6) Tundish & discharge pipe (D2) - open either valve gradually to produce a
full bore discharge into tundish and D2 without any back pressure;
7) Pressure reducing valve - check that the correct outlet pressure is being
maintained by recording the pressure at an in-line terminal fitting e.g. tap.
Ensure that all thermostats are adjusted for the correct temperature setting,
this should be between 60 and 65°C.
To ensure efficient and safe operation, and to maintain the warranty, it is

necesary to ensure the appliance is serviced annually by a competent
person.
After servicing, preliminary electrical system checks must be carried out to
ensure electrical safety (i.e. polarity, earth continuity, resistance to earth and
short circuit).
To drain the cylinder it is necessary to proceed as follows:
1) Close the mains supply service valve;
2) Open hot water taps;
3) Attach a hose and open the drain cock and allow the cylinder to empty,
taking care of hot water contained in the cylinder.
(Pumping the water out will completely drain the cylinder)
Magnesium Anodes (stD and sti models only)
No longer than every 12 months, the installer should check the magnesium
anti-corrosion anodes (consult the label on the face of the unit for the correct
location). Assessment of the condition of the bottom anode (where fitted)
can be made by judging the condition of the top anode.
Removal of anodes;
1) Close the mains supply service valve;
2) Open hot water taps;
3) Attach a hose and open the drain cock and allow the cylinder to empty;
4) The anodes are removed by unscrewing;
EXAMINE THE ANODES AND IF THE DIAMETER IS LESS THAN 10mm
replace both anodes.
The use of an approved P.T.F.E. sealing tape is required to ensure watertight
connection for anodes.
thermal cut-out(s)
If the thermal cut-out has operated the cause must be found before
resetting.
immersion Heater(s)
Should the immersion heater be scaled, we would recommend it be
replaced.
