Cleaning
In the event that sediments build up on the surfaces
of the quartz sleeve occasional cleaning will be
required. This is dependent on the nature of the
water supply and its pre-treatment; therefore, no firm
guidelines can be given on how regular this is will
be needed. Less sediment may be experienced when
the unit is vertical. The unit should be inspected after
a few months use to give an indication to the amount
of cleaning necessary. Where possible look into the
unit using a torch once the lamp has been removed.
Where this is not possible the quartz sleeve will need
to be removed as follows:
1. Turn off the power and remove the lamp as above
2. Turn off the water supply, isolate the input and
output and drain the unit
3. Unscrew end seal; remove the shim and O-ring
seal. Remove the quartz tube. Note: Care must
be taken when removing quartz tube, as it is not
supported inside the chamber. To avoid breakage,
it must be kept parallel with the axis of the unit
when being changed
4. Clean the outside of the sleeves using a mild
abrasive such as wire wool or domestic scourer -
a 10% solution of citric acid will help remove any
hard deposits. Vigorous scrubbing will remove
scale but will not scratch the quartz sleeve. When
the quartz is clean, the friction experienced when
cleaning the sleeve will be dramatically reduced.
Do not use an industrial scourer, as these grades
may be impregnated with abrasives which may
damage the sleeve surface
5. Do not attempt to clean the inside of the quartz
sleeve – they are sealed in normal use and this is
unnecessary
6. Replace the O-ring, the shim washer, and tighten
the seal with firm hand pressure and another
quarter turn
7. Dry the unit. Turn on the water and check for leaks
8. Replace the lamp and switch on
Note: Care must be taken when handling the quartz
sleeves
