FILTER CARTRIDGE REPLACEMENT
You should change your filter cartridge when the water flow is notice-
ably reduced or at least every 6 to 12 months.
1. Turn off water to the filter. Water must be shut off from Valve A (and
Valve C if it is installed). See Fig. 1A, Page 2
2. Turn on the faucet nearest to the filter housing to release pressure.
3. Unscrew the filter canister and discard used cartridge. Wash the filter
canister with mild soap and water. Do not use harsh cleaners or hot
water.
4. Inspect the filter canister O ring. Make sure it is lightly lubricated and
completely seated in the groove. It is recommended that you replace
the O ring when you replace the filter.
5. Place a new filter cartridge into the canister, make sure it is centered
and completely seated on the bottom seal.
6. Reinstall the canister to its cap. Hand tightening is all that is required
to seal the unit. You can use a wrench to slightly give the canister an
additionl 1/2 turn, but DO NOT OVERTIGHTEN.
7. Slowly turn on water to the filter by using the upstream shut-off valve
(if there is one).
8. After installation, flush the cartridge for 5 minutes, wait one hour,
then flush again for 5 minutes before using the water.
