  • Page 2: System Specifications

    HOW YOUR CBF1 FILTER WORKS Your Rainfresh CBF1 Filter removes sediment, dirt, rust, sand & other particulate matter using a special grade of filter sand which traps the particulates down to 5 micron nominal. Once every 3-4 days, the unit backwashes to remove the trapped sediment and dump it to drain.

  • Page 3: Installation

    The automatic control valve requires a constant power supply - 120V/60 Hz AC. We recommend a GFI (ground fault interrupter) outlet within 5 feet of the CBF1 Filter. Extension cords are not recommended. If water pipes are used to ground electrical system, you will need to install a jumper wire across the filter unit.

  • Page 4: C) Installation Location

    You may choose not to treat the water spigots that go outside used for irrigation or sprinkler systems. You will have to plan the job so that you cut in to feed the CBF1 filter AFTER these spigots. Installing the CBF1 filter after the pressure tank on a well water system is the preferred location.

  • Page 5: D) Plumbing The Filter Unit

    For ease of installation, orient the inlet/outlet fittings in the direction of the inlet & outlet pipes by simply rotating them (Fig 5B) Plumb in the inlet and outlet of the CBF1 filter. Plumb in a ½” flexible plastic drain line running from the filter (elbow hose fitting) (Fig 6).

  • Page 6: E) Start-Up And Programming

    The valve has 2 levels of programming – Level 1 and Level 2. need to change any settings other than time and date. Please call Rainfresh before attempting to change any values as that can affect the performance of your unit.

    MAINTENANCE The CBF1 filter does not require any routine maintenance except ensuring that it backwashes regularly. There are no filters or parts to be replaced. Typically, after a few years of service (5-7), you may notice that some sediment is present in filtered water.
