Classic 50 GPD, 3-Stage RO Unit
Installation, Operation & Maintenance Guide
NOTE:
The life span of the filter cartridges,
including the membrane, are dependent on multiple
factors. These include the quality of the incoming
water supply (TDS levels, chlorine, etc.) as well as
the amount of use. Our recommended replacement
intervals are based on average usage.
IMPORTANT!
Flush the RO Membrane before use of RO Unit.
PREPARING MEMBRANE FOR USE
The Membrane is packaged with a preservative that must
be flushed prior to using the filtered water.
Operate the RO Unit until about 30 gallons of filtered water
have been produced.
DO NOT USE THIS WATER
as it
contains the Membrane preservative. Discard the water.
The unit is now ready to for use.
UNIT MAINTENANCE
Weekly Maintenance
The Classic RO Unit includes a Flush Valve to prolong
the life of the Membrane. It is important to periodically
open the Flush Valve for 45 seconds prior to making
filtered water. This will clear debris that may have
built-up on the Membrane.
6-Month Maintenance
Replace Sediment Cartridge (Item # 330088)
This will help prolong the Membrane life.
Replace the Carbon Cartridge (Item # 330090) at least
once every 6 months or when chlorine breakthrough
occurs. This will help prolong the Membrane life.
24-Month Maintenance
Replacement of 50 GPD Membrane (Item # 330084)
OPERATION & CONSIDERATIONS
• Operating the Classic RO Unit using softened feed water
greatly reduces the chances of Membrane failure.
• Clear canisters have a limited life and should be replaced
on an annual basis to prevent possible failure.
• Operating pressure less than 40 PSI may require
a booster pump.
• Operating pressure greater than 80 PSI requires
a pressure regulator.
• With initial operation, check for leaks. If a leak is observed,
verify that the tubing is pushed into the push-fitting far
enough to seal the tubing against the O-ring and that the
canisters and caps are sealed properly with their O-rings.
• Many of the components in the Classic RO Unit are plastic
and subject to damage by ultraviolet light.
• Never store or operate the unit in direct sunlight
or other bright lights.
• Do not store or operate the unit in temperatures
above 100°F.
• Do not store or operate the unit in freezing temperatures.
• Do not leave the unit unattended while connected to
a water supply.
