CONNECTING AND DISCONNECT QUICK CONNECT FITTINGS
Quick connect
fi
ttings can be found on the high pressure switch located on the top of the RO/DI system
main unit.
REVERSE OSMOSIS MEMBRANE INSTALLATION
1. Begin by disconnecting the 1/4” tube from the connector attached to the membrane housing
cap or pressure gauge, by completely unscrewing the collet securing the RO tube. There are
two RO membranes, one with a pressure gauge, and one with an elbow
fi
tting.
2. Unscrew the cap from the membrane housing and insert the membrane
fi
rmly into the housing
ensuring that the end with the 2 rubber o-rings is inserted
fi
rst. Twisting the membrane while
inserting can assist the connector to seat properly in the housing. Once fully inserted, no part of
the membrane will protrude from the membrane housing.
3. Once the membrane has been
fi
rmly seated, seal the membrane housing by replacing the cap
and tightening.
4. Reconnect the RO tubes ensuring they are connected back to their original connectors, making
sure to tighten the collets securely.
FILTER INSTALLATION INSTRUCTIONS
It
is critical that the membrane is pushed in
fi
rmly and as far as it can possibly go. Not
doing so could allow high TDS water to bypass the membrane and make its way into
your product water, exhausting your DI resin prematurely.
Remove the tube by holding the round retention
ring tightly against the
fi
tting then pulling the
tubing away from the
fi
tting while twisting. The
tubing should slowly release from the
fi
tting.
Push Connect
fi
ttings are connected by
fi
rmly
pushing one end of the tube into the
fi
tting. It is
important to push the tube all the way into the
fi
tting for a complete seal.

Connecting Tube To Quick Connect Fittings:
The frequency at which you will need to replace your RO Membrane(s) will vary based
on the the quality of your home’s tap water and how much water you have
produced/
fi
ltered with the system. We recommend changing your RO Membrane
every 18 months to 2 years as a general rule.
