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. Once you program the unit at the time of installation, the backwash process happens
automatically. After a few years of use (over 5), you may notice a drop in water quality, at which point, the filter media only
needs to be replaced. Please call Rainfresh to order replacement filter sand.
SAFETY PRECAUTIONS
-
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 pump flow rate must 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 may need to
either change the well pump or call Rainfresh for a custom size unit that will operate within your pump
specifications.
-
Install a pressure regulator and water hammer arrestor if pressure exceeds maximum rating at any time.
Note:
If
daytime pressure is over 80 psi, night time pressure may exceed maximum pressure rating.
-
Do not install on water that is microbiologically unsafe without adequate disinfection before or after the unit. For
effective disinfection install a Rainfresh Drinking Water System or Rainfresh UV disinfection system.
-
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
-
Protect your unit from freezing
- drain the unit if freezing temperatures exist.
-
NOTE: IF SOLDER TYPE FITTINGS ARE USED DO NOT USE torch near inlet/outlet connections.
All solder joints
should be made before joining pipe to filter head. Use only lead-free solder and flux.
-
DO NOT over-tighten
metal fittings on to unit connections.
-
Place the unit on a flat level surface. Do not place shims under the unit to level it. The weight of the unit full of
water and salt can cause the cabinet to crack at the shim.
-
The unit should only be moved by 2 or more people due to heavy weight. Failure to do so can result in back or other
injury.
-
The unit must be installed in an area where there is reasonable access to the chemical tank and service, if required.
