Reef Pure RO/DI Systems have been designed to produce up to 50 Gallons Per Day (189 Litres Per Day)
for Essentials/Essentials+ systems and 100 Gallons Per Day (378 Litres Per Day) for Premium systems. That is
approximately 7.8 Litres per hour for Essentials/Essentials+ systems and 15.8 litres per hour for Premium
systems.
There are a number of environmental factors that can vary the amount of water being produced by
your system and these include; tap water pressure, water temperature and the TDS of your tap water.
The recommended minimum water pressure required to operate correctly is 65 psi. If the feed in water
pressure is below 65 psi, you will experience a reduction in overall performance. This will include a
reduced rate of RO/DI water production and a lower salt rejection from your RO membrane, resulting in
faster deionisation resin consumption.
Likewise, higher pressures can result in increased water production rates and better system
performance. The maximum acceptable pressure for your RO/DI system is 100 psi.
If your home’s water pressure is below 65 psi, we strongly recommended the installation of a HF-8367 RO
Booster Pump (sold separately).
Most RO/DI systems are designed to work with a 4:1 to 2:1 wastewater to production water ratio. This
means that for every 1 litre of RO/DI water produced, 2 to 4 litres will be diverted to the wastewater line.
This water is not suitable for use in your reef aquarium as it contains all of the rejected salts that your RO
membrane has filtered out.
However, the Reef Pure RO Systems Premium range of systems halve the amount of wastewater
produced and almost double the amount of RO/DI water produced. This is achieved by adding an
additional RO membrane in series. The second membrane is fed the wastewater from the first
membrane, which would have otherwise been discarded by the system.
Never use hot water (water warmer than 45℃). Using warm or hot water will cause
permanent damage to your RO membrane, requiring the membrane to be replaced.
Do not use the system in direct sun as it will deplete deionisation resin cartridges and
can quickly heat the system causing permanent damage to the RO membrane.

CONNECTING AND DISCONNECT QUICK CONNECT FITTINGS
Quick connect fittings can be found throughout the RO/DI system and can be connected and
disconnected by following the below instructions. We recommend familiarising yourself with them
before moving on.
REVERSE OSMOSIS MEMBRANE INSTALLATION
1. Begin by disconnecting the 1/4” tube from the connector attached to the membrane housing
cap or pressure gauge, depending on your model. Note: Premium systems feature two RO
membranes, one with a pressure gauge, and one with a quick-connect fitting.
2. Unscrew the cap from the membrane housing and insert the membrane firmly into the housing
ensuring that the end with the 2 rubber o-rings is inserted first. Twisting the membrane slightly
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 firmly seated, seal the membrane housing by replacing the cap
and tightening.
4. Reconnect the RO tube(s) ensuring they are connected back to their original connectors. Note:
Typically tubes that were connected to pressure gauges can be easily identified by the distinct
groove left by the connector. If unsure refer the the flow diagrams on pages 9 and 10.
FILTER INSTALLATION INSTRUCTIONS
It is critical that the membrane is pushed in firmly 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 fitting then pulling the
tubing away from the fitting while twisting. The
tubing should slowly release from the fitting.
Push Connect fittings are connected by firmly
pushing one end of the tube into the fitting. It is
important to push the tube all the way into the
fitting 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/filtered with the system. We recommend changing your RO Membrane
every 18 months to 2 years as a general rule.
