HOW YOUR CBF1 FILTER WORKS
Your Rainfresh CBF1 Filter re oves sedi ent, dirt, rust, sand & other particulate atter using a special grade of filter sand
which traps the particulates down to 5 icron no inal. Once every 3-4 days, the unit backwashes to re ove the trapped
sedi ent and du p it to drain. Once you progra the unit at the ti e of installation, the backwash process happens
auto atically. After a few years of use (over 5), you ay notice a drop in water quality, at which point, the filter edia only
needs to be replaced. Please call Rainfresh to order replace ent filter sand.
SAFETY RECAUTIONS
-Follow all applicable province/state and local regulations.
-Handle the filter carefully. Do not lie on side, turn upside down, drop or drag.
CAUTIONS BEFORE INSTALLATION
-To operate properly, the well pu p flow rate ust exceed the backwash flow rate (5 US GPM (19 LPM)). If your
well pump does not deliver this flow rate, do not install the unit as it will not work properly. You ay need to
either change the well pu p or call Rainfresh for a custo size unit that will operate within your pu p
specifications.
-Install a pressure regulator and water ha er arrestor if pressure exceeds axi u rating at any ti e. Note: If
dayti e pressure is over 80 psi, night ti e pressure ay exceed axi u pressure rating.
-Do not install on water that is icrobiologically unsafe without adequate disinfection before or after the unit. For
effective disinfection install a Rainfresh Drinking Water Syste or Rainfresh UV disinfection syste .
-For use on cold water only.
-Only use thread seal tape (such as Teflon® tape) for fitting connections into unit. DO NOT USE pipe dope or
chemical sealants to make connections
-Do not use Vaseline or other petroleum-based lubricants on seals
-rotect your unit from freezing - drain the unit if freezing te peratures exist.
-NOTE: IF SOLDER TY E FITTINGS ARE USED DO NOT USE torch near inlet/outlet connections. All solder joints
should be ade before joining pipe to filter head. Use only lead-free solder and flux.
-DO NOT over-tighten etal fittings on to unit connections.
-Place the unit on a flat level surface. Do not place shi s under the unit to level it. The weight of the unit full of
water and salt can cause the cabinet to crack at the shi .
-The unit should only be oved by 2 or ore people due to heavy weight. Failure to do so can result in back or other
injury.
-The unit ust be installed in an area where there is reasonable access to the che ical tank and service, if required.
