Maintenance Instructions
Before
any maintenance turn off the water supply to the product and open a downstream fixture for a
few minutes or until the water flow stops. Close the downstream fixture, and then press the red
buttons on top of the filter housing caps to release the pressure in the system. You may now begin
maintenance. Place a tray underneath, if required, to catch any water that splashes.
To resume flow after maintenance
, slowly turn on the water supply to the product and check for
leaks. Open a fixture downstream of the product for 3 minutes to flush water through the system and
remove any air pockets. Close the fixture downstream and then check for leaks again. You may now
resume water usage.
Filter Cartridge Replacement
Replacement of the filter cartridges is recommended at least every 1 year, or as required due to the
supply water quality.
Steps to replace the filter cartridge (recommended at least every 1 year or as required):
1.
Read the general maintenance instructions before
starting the filter cartridge replacement.
2.
After isolating and release the system pressure. Loosen
the filter housing from the cap using the spanner to assist
(turn clockwise when looking from above).
3.
Carefully unscrew the filter housing, taking care as the
weight of the filter housing with water can be heavy.
4.
Empty excess water from the housing and remove the
filter cartridge. Please dispose of the filter cartridge
responsibly.
5.
If necessary, clean the housing with dish soap and warm
water and then rinse thoroughly.
6.
Remove all packaging from the replacement filter
cartridge. Record the model number of the cartridges you
use & install date in the maintenance log at the back of
this manual.
7.
Insert the filter cartridge into the filter housing. For CTO
filters, ensure that the rubber seal on the top and bottom
are firmly in place before inserting into the housing.
Ensure the filter cartridge is correctly seated on the spigot
at the base of the filter housing.
8.
Check O-rings are clean, undamaged and assembled
correctly to the filter housing. Replace if necessary and
lubricate using only 100% silicone food grade lubricant.
9.
Hold the filter housing vertically whilst screwing the filter
housing back into the cap. Ensure the top spigot is
aligned with the center of the filter housing. Hand tighten
the housing until firm, being careful not to overtighten. Do
not overtighten the housings.
10.
Read the general maintenance instructions on how to
restart flow after replacing the cartridges.
