Replacement Procedure

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. 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 soap and warm water and rinse thoroughly. Check O-Rings for 

damage and replace if necessary.

4   Check 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. 
Remember to record the model number of the cartridges you use & install date.

6   Hold bowls upright while screwing in the housings. Make certain that the spigot in 

the housing heads is located centrally to the cartridges to make a good seal. Use 
the spanner to tighten the bowl until firm. DO NOT OVER TIGHTEN.

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 Hybrid 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.
