Omni Installation Notices

Omni Filter Owner Manuals

  • Install filter on cold water only. Do not use on water lines exceeding 100 degrees F (38 degrees C). Water pressure minimum is 25 psi and the maximum is 125 psi.

  • Protect unit from direct sunlight and freezing temperatures. Keep above 35 degrees F.

  • Avoid exposure of filter housing to torch.

  • Do not use pipe dope or similar compounds. They can ruin plastic. Use Teflon tape to seal pipe thread joints.

  • Keep unit clean with soap and water. Do not use spray cleaners or insecticides near unit.

  • Intended for indoor, non-commercial use only.

  • For extended periods of non-use turn the water off and remove the filter cartridge. Place the cartridge in a plastic bag, seal, and refrigerate.

  • Safety glasses must be worn during installation.

  • Tubing and hose dimensions are based on outside diameters (OD).
    For water line sizes other than those listed, consult a plumber or hardware store.

  • Before using the water, flush the new filter for 30 minutes.

  • Run drinking or cooking water for 5 - 7 seconds prior to collecting the water for use.

  • Change cartridge stated at manufacturer's suggested interval or sooner is you notice a change in color, taste or low water pressure.

  • Filter is not a water purifier and is not intended for use with contaminated water.

  • Comply with all state and local laws regarding the installation of water treatment devices.

  • Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

  • The rubber O-ring provides the water tight seal between the cap and the housing. It is important that the O-ring be properly seated in the groove in the housing or a water leak could occur.

  • The contaminants or other substances removed or reduced by this water filter device are not necessarily in your water.

  • Use of ANY cartridge other than an Omni filter will void your warranty.

  • Replace tank O-ring with every second filter cartridge change.

  • DO NOT use wrench to tighten tank.

  • Use wrench ONLY for tank removal.
