Lamp Installation
Once the Steriflo ® Treatment Chamber has been connected to the pipework, the
installation should be checked for water leaks. For installations using a pressure
pump, connect 3-pin plug to main power socket, prime the pump and fill chamber
with water.
Once checked, disconnect power to the pump and remove 3-pin plug from
socket.
Attach the “DO NOT LOOK AT LAMP” sticker in an obvious position on the
treatment chamber, check that the chamber is clean to ensure the sticker will
adhere correctly.
The Quartz Sleeve is pre-installed in the treatment chamber, and provided the
endcap has not been disturbed or undone, is able to withstand well in excess of
the maximum operating pressures.
If the chamber test is successful, it is now time to insert the lamp.
Expose the connection end of the lamp from its transport tube and protective
wrapping. The lamp connection socket is “keyed” to ensure correct alignment.
Carefully remove the tube fully from its transport tube, touching the lamp as little as
possible. Handle the lamp by the ends where possible. Wipe with clean cloth and
methylated spirits if fingerprints or dirt need removing. Slide the lamp into the
chamber, fit lamp connection socket and then fasten the end washer into the
endcap, with the screws provided.
Operation
Once all leak testing and lamp fitment has been completed, prime pump and
connect pump lead to supplied outlet. Connect three pin plug to power outlet and
switch on. Open valves and allow water to fill the chamber. The “Mains On”
Amber LED will be illuminated and the red alarm light will flash slowly. Note: If
chamber does not fill with water within two minutes, reprime the pump to avoid
damage to the lamp.
Allow two minutes for the UV lamp to reach full intensity before starting water flow.
Full lamp performance for a new installation will be achieved in 24 hours. On a
new installation where no other form of sterilisation has been in constant usage,
we recommend flushing the pipework with a suitable sanitiser such as Steritank HP
or Davey Acquasafe - for dosage refer to product instructions. This solution should
be left in the piping for at least an hour and preferably overnight.
The sanitising solution can be dosed to the water tank or if necessary added as a
shot dose to the bowl of any filter housing installed with the UV system and slowly
flushed into the piping.
If dosed to the water tank the Steritank HP or Davey Acquasafe can be left in the
water as it is tasteless and suitable for use in drinking water. If added as a shot
dose it should be rinsed out through a nearby tap.
Davey Water Products can not accept responsibility for loss or damage
resulting from incorrect or unauthorised installations.
