Changing The Filter Cartridges

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
Adapt-a-Valve. 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 as shown in the pictures below.
6 Month System Maintenance
Replace:
√ One sediment filter
√ One carbon pre-filter
Annual Maintenance
Replace:
√ One sediment filter
√ One carbon pre-filter
√ One carbon post-filter
This is a good time to check the air pressure in your storage
Tip:
tank. For instructions please see page 14.
Flush first tank full after completing the annual maintenance.
Note:
Step 1
Place a towel under the RO module to catch any excess water that
may drip out from the filters during the changeover.
Step 2
To remove a filter cartridge:
valved head above the filter. Pull cartridge downward (from the
head) to remove. Release button and discard old filter.
Step 3
To install a filter cartridge:
the cartridge into the valved head until you hear an audible "click"
(the button does not need to be pressed to install new filters).
To reset the electronic monitor during replacement of filters, simply
Note:
pry out the black rubber battery drawer from the faucet handle using
a flat head screwdriver, wait a few moments and reinsert.
This reverse osmosis system contains a replaceable component (the RO membrane) which is critical to the
efficiency of the system. Replacement of this reverse osmosis membrane should be with one of identical
specifications as defined by Premier to assure the same efficiency and contaminant reduction performance.
Membrane Replacement (2 - 5 Years)
Replace:
√ One Membrane
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. Premier recommends replacing the membrane when TDS reduction falls below
75%.
A water sample may be sent to Premier for a free diagnosis of your membranes performance. To send
a water sample, use 2 clean containers and fill 1/2 cup of tap water in one container and 1/2 cup of RO water in
2nd container. Clearly label each sample. Send the samples to the address listed on the cover of this manual
attention "Water Samples". Premier will test the water and mail or call you with the results.
