PREVENTIVE MAINTENANCE
These recommendations are intended to maximize efficiency of RO water production by your system.
1)
Filter maintenance
a) It is OK to store filters on the shelf for several years.
b) To store the sealed, unopened filter, we recommend that it be kept in an air tight container. This
prolongs the shelf life of the carbon filter (particularly filter was ordered more than one year before its
intended use) and avoid having the filter absorb any possible odor from the air
2)
Membrane maintenance
a) The dry packed membrane usually has a two-year shelf life. To prolong the shelf life, we recommend
keeping unopened dry membrane in a refrigerator.
b) Once the membrane is in use, we recommend running the RO system every day for at least 10-15
minutes (about 1 gallon or 4 liters of drinking water). This helps to maintain the membrane
performance.
c) If the RO system is not used for over a week, drain the storage tank first. Then fill the tank and drain it
twice. Your RO system is now ready to use again.
Place a towel under the RO module to catch any excess water that may drip out from the filters
during the changeover.
Step 1
Your RO module is equipped with valved heads which will automatically turn off the water supply
to each filter when the filter is released, thus you do not need to turn off the incoming water supply
at the angle stop adapter.
The RO faucet must be off when filters are replaced.
To make the
removal of the filter cartridges easier, the heads & cartridges may be swiveled up to 90 degrees.
Step 2
To install a filter cartridge:
Remove the seal cap and insert the cartridge into the valved head
with the label facing to the left (9 o’clock position) rotating it clockwise 1/4 turn.
Step 3
To remove a filter cartridge:
Grasp the cartridge and pull it towards you. Rotate the cartridge 1/4
turn counter clockwise to remove.
Membrane Replacement (2 - 5 Years)
√ One 50GPD Membrane (P/N: KC5005 11”)
Replace:
Membranes have a life expectancy between 2 and 5 years, depending on the incoming water conditions
and the amount the RO system is used. This reverse osmosis membrane is critical for effective reduction of total
dissolved solids (TDS). The product water should be tested periodically to verify that the system is performing
satisfactorily.
Normally, a membrane would be replaced during a semiannual or annual filter change. However, if at any
time you notice a reduction in water production or an unpleasant taste in the reverse osmosis water, it could
be time to replace the membrane. U
DI
recommends replacing the membrane when TDS reduction falls below
75%.
Annual Maintenance
-
(Sanitization Recommended, See Page 10)
√ One sediment pre-filter
(P/N: KC5002 11”)
√ One carbon pre-filter
(P/N: KC5003 11”)
√ One KDF/GAC carbon pre-filter
(P/N: KC5004 11”)
√ One carbon post-filter
(P/N: KC5006 11”)
Replace:
11
Flush two tank fulls after completing the annual maintenance.
