Maintenance

e) COMMISSIONING

- Check that all the necessary components are supplied and for those not

factory fitted, that they are the type recommended by the manufacturer

for the particular water heater.

- Check that the water heater/components are undamaged.

- Check that the discharge pipe is plumbed so that it falls continuously and

that no taps, valves or other shut-off devices are installed in the pipe.

- 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

a) For the user

anode must be checked every year. 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.

b) For the installer

WARNING:

Access to the electrical components, the magnesium anode and water

container is gained by unscrewing the 4 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:

Switch off the power first
