
Plugged filter as the result of infrequent backwashing. Alternatively,
backwashing too much breaks the media down faster. Not changing filter
media properly or when required can lead to serious contamination.

A broken distributor tube is a mechanical failure that required media to be
replaced. This is a very rare event generally occurring only after filter media
replacement.
NOTE: Run the filter regeneration cycle following system storage or extended
periods of time away from the system to refresh and retreat your water prior to
consumption.
Replacing Cartridge Filters
The life span of cartridge filters varies depending on the quality of the water being
treated. Filters need to be changed when there is a difference of 5 psi or greater
between the incoming pressure gauge and the outgoing pressure gauge:
Incoming flow = 50 psi
>
Outgoing flow = 45 psi or lower
requires > cartridge replacement
Follow all instructions included with the cartridge filter. To change the cartridge filters,
complete the following:
1. Shut off incoming water flow.
2. Release the water pressure on the system by opening the downstream tap
closest to the system. Close tap after water flow out of the tap stops.
3. Use the filter wrench provided with the cartridge filters to loosen the filter housing
from the base by turning the housing counter-clockwise.
4. Make sure you wear rubber or latex gloves prior to removing the used filters
– the
used cartridge filters may contain bio-hazardous material that has been filtered
from the water.
5. Dispose of the filters appropriately as they will be very hazardous and thoroughly
wash hands with soap and water after contact.
6. Put on fresh gloves to ensure the new cartridges are not contaminated with
residue on the old gloves or any contaminants that occur naturally on skin.
7. Remove the new filters from plastic and place them in the filter housing. The
sediment filter should be installed closest to the ozone system. The activated
carbon filter is installed after the system.
IMPORTANT : Make sure the filters are installed in the proper sequence.
8. Ensure that the o-ring on the top of the filter housing is in good condition and in
the groove of the filter housing prior to re-attaching the housing to the base.
9. Tighten the housing into the base with the filter wrench by turning the housing
clockwise until it fits snugly.
