6 Month System Maintenance
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
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.
Step 2
To install a filter cartridge:
Remove the seal cap and insert the
cartridge into the valved head twisting it clockwise until full seated.
Step 3
To remove a filter cartridge:
Twist filter cartridge counter
clockwise until cartridge pops out of the filter head.
Changing The Filter Cartridges
Membrane Replacement (2 - 5 Years)
√
One Membrane (50 GPD Green Label P/N: 114110) 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. 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.
To reset the electronic monitor during replacement of filters, simply
slide out the battery from the base of the faucet and reinsert.
Note:
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.

6 Month System Maintenance
Tip:
This is a good time to check the air pressure in your storage
tank. For instructions please see page 14.
Flush first tank full after completing the annual maintenance.
