OTHER FEATURES
Control Operation During a Power Failure
In the event of a power failure, the valve will keep track of the time and day for 48 hours. The programmed settings
are stored in a non-volatile memory and will not be lost during a power failure. If power fails while the unit is in
backwash, the valve will finish backwash after power is restored. If the valve misses a scheduled backwash due to a
power failure, it will queue backwash at the next backwash time once power is restored.
New Sounds
You may notice new sounds as your filter operates. The backwash cycle lasts approximately 20 minutes. During this
time, you may hear water running intermittently to the drain.
Manual Bypass
In the case of emergency, such as a leak, you can isolate your filter system from the water supply using the bypass
valve located at the back of the control (see page 4). To resume filtered water service, open bypass valve by rotating
the knobs counterclockwise.
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. At this time you will need to replace the filter sand in the unit, which can be purchased
from Rainfresh. Please call customer service at 1800-667-8072.
Care of your CBF1 filter
To retain the attractive appearance of your new filter, clean occasionally with mild soap solution. Do not use
abrasive cleaners, ammonia or solvents. Ensure that there is no dust or debris on the bypass valve.
Winterizing the system
If the unit is to be winterized, the best way is to close the by-pass valve and unscrew the 2 screws adjacent to the by-
pass valves that hold the unit and the by-pass valve together, and carry the unit to a place where it will not be
subject to freezing temperatures.
