Replacing the UV lamp – Yearly
Carefully unwrap the replacement lamp. The packaging can be reused to return your
old lamp to your place of purchase for recycling. Do not break the old lamp and do
not dispose of it in general waste.
– Disconnect power by unplugging the cord set.
– Depressurise the system and drain the UV chamber by removing the drain plug.
Remember to put the plug back on when the chamber is empty.
– Turn off water supply to the inlet of the Steriflo.
– Unscrew the earth connection
– Unscrew the 2 small screws holding the endcap on.
– This will expose the wiring for the lamp. Disconnect the lamp and remove it
straight up. Only handle the lamp by the ceramic-coated ends.
– Insert the new lamp and reconnect the wiring. Push the cords into the top of the
quartz sleeve so that the 2 small screws can be inserted.
– Connect the earth wire.
– Plug in the power and turn on. Allow the lamp to run for 2 minutes, turn the water on.
– Securely wrap the used lamp in the packaging and return it to your place of
purchase for return to Davey Water Products and recycling.
– If alarm sounds, turn power off for 5 minutes to allow internal reset of the power
supply.
Sediment Cartridge Filter Life
Once the housing is properly installed, a reduction in flow/pressure (to such an extent
as to cause inconvenience) will indicate when the cartridge is becoming clogged and
needs replacing or cleaning. Sediment cartridges should be replaced or cleaned and
sanitised when the water flow has been noticeably reduced or after 3-6 months -
whichever comes first (this is for hygiene reasons).
NOTE: Actual filtration/purification life of cartridge can vary with the condition
of incoming water.
