Filter Cartridge Replacement
A.
Turn off water supply to filter. Depress blue pressure-relief button to release
trapped air.
B.
Place a bucket or container under the housing if needing to protect surface
underneath from any spilled water.
C.
Remove bottom of filter housing by turning clockwise (if required use spanner
included with product upon initial purchase).
NOTE:
If turning off water supply to the filter, this will also turn off water to the rest
of the home. Be sure to fill a bucket of water first to allow you to clean the housing
after it has been removed.
D.
Locate and remove large O-ring on the top of the filter housing base, wipe clean
of lubricant and set aside.
Discard used cartridge. Rinse out bottom of housing and fill 1/3 full with water.
Add 2 tablespoons of bleach and scrub cap and bottom of housing with non-
abrasive sponge or cloth. Rinse thoroughly.
Lubricate O-ring with clean silicone grease. Insert O-ring back into groove and
smooth into place with finger.
NOTE:
This step is important to ensure proper housing seal. Make sure O-ring is
seated level in the groove.
Insert new cartridge into bottom of housing.
E.
Screw bottom of housing onto the cap and hand-tighten. Do not over-tighten.
Turn on water supply slowly to allow filter to fill with water. Depress blue
pressure-relief buttons to release trapped air. Flush cartridge for 5 minutes before
use. Flush again for 10 minutes before using water. Check for leaks before
leaving installation. If leaks present, tighten with spanner provided.
Troubleshooting
1. Leak between cap and bottom of filter housing:
a.
Turn off water supply and press the blue pressure-relief button. Remove
bottom of housing.
b.
Clean O-ring and O-ring groove (located directly beneath threads of housing).
Lubricate O-ring with clean silicone grease and replace securely into groove.
Do not use petroleum based lubricant. Screw bottom of housing onto cap and
hand-tighten.
Do not over-tighten.
c.
Replace O-ring, should leak persist. O-ring can deteriorate over time and
periodic replacement is required.
2. Leak on inlet/outlet connections:
a.
Turn off water supply. For brass fittings, tighten nut snugly about half of a turn
with a wrench.
b.
Turn on water supply. If leaks persist, or if there are other leaks on the system,
turn off water supply. Contact your nearest Davey dealer for advice.
Maintenance
Filter housings must be maintained according to manufacturer’s instructions,
including ongoing replacement of the filter cartridge. Failure to do so will result in
poor water pressure and poor filtration results.
