Use and Care Manual
Notes
● Even though there is filtered water in the cold water lines, the hot water heater is still
full of raw water. Through normal use, this water will be replaced with filtered water in
about 2 or 3 days.
● This filter system should not be used with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before and/or after the system.
● The system should never be exposed to freezing temperatures. Damage from
temperature is not covered under warranty.
● After prolonged periods of nonuse (such as a vacation), it is recommended that the
system be flushed for at least 10 minutes before using the water.
Filter Change Instructions
1. Turn off the water supply to the system. Press the red pressure release button on the
top of the filter housing to relieve system pressure. If your system was not equipped with
a pressure relief valve, leave open a nearby faucet. This will make removing the filter
housing easier.
2. Unscrew the housing using the filter wrench included with your system, or a
commercially available “strap” type wrench.
3. Locate and remove the large O-ring using a small, clean flat head screw driver. Try
not to remove any of the lubricant. Set it aside in a clean, safe place.
4. Remove and discard the old filter cartridge.
5. Scrub the housing and cap with warm water mixed with about 2 tablespoons of
household bleach using a sponge or soft rag. Wear rubber gloves. Rinse all parts very
thoroughly!
6. Lubricate the O-ring with clean silicon grease if needed. DO NOT USE PETROLEUM
JELLY. Insert the O-ring in the filter groove and press into place. Make sure the O-ring
is seated correctly.
7. Remove the filter packaging and insert the filter cartridges into the housings, making
sure they slip over the standpipe in the bottom of the housing.
8. Align the top of the housing into the cap and hand tighten, then use the filter wrench to
fit it snug.
9. Close any open valves. Turn on the water supply slowly to allow the system to fill with
water. Inspect carefully for leaks. If a leak is found, remove the housing and inspect
the O-ring to ensure that it is seated properly, and then retighten.
10. Flush the system by turning on a few cold-water faucets. Allow the water to run until
the air and carbon has been purged. Water may be cloudy initially as the filters and
system clear of trapped air. New activated carbon filter cartridges may contain loose
carbon and air bubbles after installation.
