Cartridge Replacement Procedure
To change the filter cartridges please adhere to the following procedure:
1 Turn water supply off and relieve pressure by opening a downstream tap or pressing
the red pressure relief button on the housings.
2 Unscrew the filter bowls clockwise. If the bowl is difficult to undo, the spanner
provided may be used to make it easier. Remove old cartridges and dispose in the
correct manner.
3 Clean bowls with Puretec Housing Sanitiser or detergent and warm water and then
rinse thoroughly. Check O-rings for damage and replace if necessary.
4 Check the O-ring lubrication and if necessary apply a light coating of food grade
silicone lubricant (or similar).
5 Remove all packaging from new filter cartridges and insert into housing bowls
making sure cartridges are properly seated over the spigot in base of the bowls.
6 Hold bowls upright while screwing into the housings in an anti-clockwise direction.
Make certain that the spigot in the housing heads is located centrally to the
cartridges to make a good seal. Tighten the bowls until firm. Use the spanner to
tighen the bowls until firm. DO NOT OVER TIGHTEN. Remember to record the model
number of the cartridges you use & install date.
7 Open a downstream tap to allow air to be released and gently open water supply
allowing all air to be purged.
8 Allow water to run for 1-2 minutes to flush the system.
9 Close down stream tap and check the WU-UV system for leaks. Flush system for
1-2 minutes after any period of non-use more than 2 weeks. For a period of non-
use of 6 months or more, it may be necessary to replace the cartridges.
