Maintenance Schedule
This schedule is designed for the average potable water supply and should be followed to ensure the proper functioning
of your drinking water system.
Pre-Filter
- The pre-filter contains a 5 micron mechanical filter element. Its function is to remove suspended particles
from the feed water, thus reducing the possibility of clogging the reverse osmosis membrane. The pre-filter element should
be replaced every twelve months or earlier depending on the quality of the feed water.
Pre-Carbon Filter
-The pre-filter contains a granular activated carbon. Its function is to remove chlorine from the
incoming water to prevent any damage to the TFC membrane. The Pre-Carbon filter cartridge should be replaced every
24 months.
Reverse Osmosis Module
- The reverse osmosis module contains a semi-permeable membrane. Its function is to
separate water molecules from dissolved impurities in the feed water. This is accomplished by application of hydraulic
pressure greater than the osmotic pressure in water containing dissolved solids. The life of the membrane can be
determined by measuring the percentage of rejection of total dissolved solids in the water. The membrane should be
replaced every 24 to 36 months when its efficiency will decrease.
Post-Carbon Filter
- The post-filter contains a granular activated carbon. Its function is to remove any taste and odor
from the water prior to delivering it to the spigot. The post-filter cartridge should be replaced every 24 months.
Changing Filters
Important: This RO System contains filters, which must be replaced at regular intervals to maintain proper performance.
See Maintenance Schedule for the recommended interval for changing the filters. Local conditions may dictate more
frequent cartridge replacement. Use a drip pan to catch any water that may spill when the housings are removed. Use only
factory approved filters.
1. Close the saddle valve and open the faucet by lifting the handle.
Allow storage tank to empty.
2. Loosen and remove the appropriate filter housing(s). Discard the
cartridge(s).
3. Wash the inside of the housings using a mild detergent and a soft
cloth. Do not use abrasive cleaners or pads. Thoroughly rinse all
soap from the housing before re-assembly.
Performance Indicators
The product water needs to be tested at least once every six months. Please contact your local dealer for sampling service
or sampling kit.
