Pre-treatment (drinking water)
Pre-filtration is usually required to ensure that particulate matter does not shield
micro-organisms from the UV light. Sand filtration or 20 micron cartridge filtration
is the usual minimum. In some cases, particularly with surface water, finer
filtration may be necessary, or if cysts like Giardia or Cryptosporidium may be
present.
In this case 1 micron filtration is required, not necessarily for the whole supply,
filtration for the drinking tap only may be practical.
Lamp Installation
Once the Steriflo Treatment Chamber has been connected to the pipework, the
installation should be checked for water leaks.
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
endcaps have 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. DO NOT
INSERT THREE PIN POWER PLUG TO POWER OUTLET YET!
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.
