Replacement Procedure
Lamp Replacement Procedure
Prior to performing any work on the UV steriliser, always disconnect the power
supply first.
1 Turn water off and release the water pressure.
Parts become hot during operation.
Allow to cool before servicing.
2 Disconnect the lamp connector and ground
wire. Grip the end of the lamp and carefully
disconnect the power socket.
Slowly remove the old lamp from the chamber.
3. Check the quartz sleeve to ensure it is clean
and intact (
see steps 4 - 8 of Quartz Sleeve
Maintenance/Replacement Procedure on page 15
).
4. Remove the packaging on the new lamp. Slowly insert into chamber through the
hole of the aluminium nut end. Connect the lamp connector to the pins on the lamp.
Do not let go of the lamp until the lamp is connected to the socket (
see Fig. 6
).
Never touch the quartz (glass) and lamp surface as marks or fingerprints may
interfere with UV transmission. If lamp is soiled, please clean lamp with an alcohol
based cleaner.
5. Secure the lamp connector on the aluminium nut end. Connect the ground wire to
the chamber. Plug in power connector, the RED LED will be illuminated (when the
lamp life timer is reset in step 7 the LED will turn green).
6. Restore water supply and check the unit for leaks. Re-check the unit after 1 hour.
Note: For initial use, wait 3-5 minutes to allow water to pass through the whole
unit. Turn on a downstream tap to let water flow through the unit for 2-3 minutes to
release air and impurities from system.
7. Press and hold the silver button for 15 seconds, when an audible "beep" will sound,
indicating that the lamp life timer has been reset for a further 12 months.
We recommend replacing UV lamp annually to ensure high sterilising rate with best
water quality. Always keep UV lamp on, as power fluctuation will shorten the service
life of the UV lamp.
