Automatic Raw Water Bypass During Regeneration
The regeneration cycle can last 30 minutes after which filtered water service will be restored.
During regeneration, un-filtered water is automatically bypassed for use in the household.
Hot water should be used as little as possible during this time to prevent un-filtered water
from filling the water heater. This is why automatic regeneration is set for sometime during
the night and manual regenerations should be performed when little or no water will be used
in the household.
Normal regeneration time is 2:00 AM.
New Sounds
You may notice new sounds as your filter operates. The regeneration cycle lasts up to 30
minutes. During this time, you may hear water running intermittently to the drain.
Manual Bypass
In the case of emergency you can isolate your water filter from the water supply using the
bypass valve located at the back of the control. In normal operation the bypass is open with
the on/off knobs in line with the inlet and outlet pipes.
To isolate the filter, simply rotate the knobs clockwise (as indicated by the word BYPASS
and arrow) until they lock. You can use your water related fixtures and appliances as the wa-
ter supply is bypassing the filter. However, the water you use will be hard. To resume water
service, open bypass valve by rotating the knobs counterclockwise.
Maintenance
Maintenance of your new water filter requires very little time or effort but it is essential. Reg-
ular maintenance will ensure many years of efficient and trouble-free operation.
1. Periodically make sure your pump is performing satisfactorily to ensure sufficient water is
available for backwashing the filter.
2. Periodically test your raw and filtered water to ensure conditions are still the same for
your original settings and that the unit is working they way it is intended to. Water testing
is often the best way to determine when the filter media will require replacement.
3. Periodically check that the drain line is clear and free from any obstructions.
