- Check that the

- Check that the discharge pipe drains safely to waste and is readily visible. - Check, in the case where some components are not factory fitted, that they are marked so as to refer to the warning label on the water heater. - Open all outlet taps. - Turn on the mains water supply. - Close taps in turn as water flow stabilises with no air bubbles. - Check for leaks. - Check that no water is passing through the safety valve(s). - Test the operation of the safety valve(s) by lifting/turning the lever/knob, and observing that water flows through and safely to waste. - Switch on electricity and set thermostat to at 60°C to reduce the build up of scale in hard water areas. - Check the water heats up. - Check that is secure and visible on the heater and related warning labels are fitted to the controls. - Demonstrate operation to user, including operation of safety valve(s) and what to do if it/they operate(s). - Give this handbook to the user and discuss future maintenance. - Drain and refill the entire system ensuring it is flushed in accordance with BS6700.

Maintenance a) For the user In order to obtain the best performance from the heater, the sacrificial anode must be checked every year and replaced as necessary. If the heating element is heavily coated with scale we recommend descaling and removing any lime deposit from the heater at the time of this inspection. Where the additional cold water controls are fitted, the expansion vessel will need to be recharged by the installer. Important note: The heater must be serviced annually. Failure to service which includes inspection and replacement of the sacrificial anode will invalidate warranty. b) For the installer WARNING: Switch off the power first Access to the electrical components, the magnesium anode and water container is gained by unscrewing the 2 screws on the front cover. If the thermal cut-out has operated the cause must be found before resetting. To drain the heater close the service valve and: i) for under-sink models disconnect pipes and removed the heater from the wall. ii) for over-sink models undo the cold water supply pipe and open a hot water tap. The heating element may be removed (after taking out the thermostat phials on model 30 L) by undoing the M6 nut. The assembly should then be turned through 90° anti-clockwise to ease removal from the water container. Once the element is free from the water container the anode may then be inspected and removed if necessary. When reassembling the cover make sure that the regulation knob is coupled with the thermostat. Check controls (where fitted) as per the following: - Line strainer - with the water supply turned off remove screen from strainer and clean of any detritus; - Expansion vessel - with the water supply turned off and taps open, check expansion vessel pressure and top up as necessary; - Temperature & pressure relief valve - with the water supply turned on, check manually by lifting the test lever/turning the test knob (ensure valve closes after testing); - Expansion relief valve - check manually by turning the test knob (ensure valve closes after testing); - Discharge pipes (D1) - from both temperature & pressure relief and expansion relief valve for obstructions; - Tundish & discharge pipe (D2)- open either valve gradually to produce a full bore discharge into tundish and D2 without any back pressure; - Pressure reducing valve - check that the correct outlet pressure is being maintained by recording the pressure at an in-line terminal fitting i.e. tap. 19
