Precautions
WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without
adequate disinfection before or after the system.
CAUTION: Filter must be protected against freezing, which can cause cracking of the filter and water
leakage.
NOTE:
• Make certain that installation complies with all state and local laws and
regulations.
• For cold water use only.
• A drinking water filter cartridge may contain carbon fines (very fine black powder). After installation
flush the cartridge for 5 minutes to remove the fines before using the water. You should run the tap at
least 20 seconds prior to using water for drinking or cooking purposes.
• The replacement filter cartridge has a service life of about 2,000 gallons or one recreational season
of use. Changes in taste, odor, color, and flow of the water being filtered indicate that the cartridge
should be replaced.
• The contaminants or other substances removed or reduced by this water
treatment device are not necessarily in your water.
Installation
• For use with 3/4-inch flexible hose couplings. It is recommended that you install the filter between
two flexible hoses to prevent it from being damaged. The short hose supplied with the RV-800 may be
attached to either end of the filter.
• Please read all precautions and instructions before installing and using your RV water filter.
• Numbered diagrams correspond with numbered steps.
1. Turn off water supply (A). Remove plastic plugs (B) from ends of filter. DO NOT discard plugs; they
may be used to store the filter between usages. Make sure the rubber washer (C) is inserted into
inlet of filter.
NOTE: Water must flow through filter in the proper direction. INLET and OUTLET are marked clearly on
either end of the filter.
2. (A) Attach the inlet (female) end of filter to the supply hose. Turn on water (B) and flush carbon
filter (C) for 5 minutes to remove carbon fines before using the water. Turn off water supply.
3. (A) Attach outlet (male) end of filter to second hose. Installation is complete! Turn on water supply
(B) to use filter.
