OPERATION DESCRIPTION
(how the system functions)
1. The incoming feed water (3/8” Black line) is passed through a 0.2 micron ZetaZorb™ Sediment Filter. This filter is
required to remove excess turbidity (particulate matter) that may cause the carbon block filter to plug.
2. The second stage of filtration is a 0.5 micron carbon block prefilter. This filter removes organics and chlorine from the
feed water that can damage the membrane.
3. The third filtration stage of the system is a high rejection thin film composite (TFC) reverse osmosis membrane. It
removes over 98% of most inorganic salts, all microorganisms and organics above 100 diatoms molecular weight. A
Flow Restrictor, located in the waste water line, is preadjusted for your location’s maximum tap water temperature.
This Flow Restrictor regulates the amount of water going to drain and determines the waste-to-product ratio. At
the maximum yearly tap water temperature, the ratio should be close to 1:1. As the water gets colder, the ratio will
increase by a small factor.
4. The fourth and fifth stage filter are our MAXCAP
®
DI cartridge followed by our SilicaBuster™ DI cartridge. These two
cartridges remove the remaining silicates, phosphates, and nitrates that get by the RO membrane.
High and Low Float Operation:
1. Floats are to be mounted horizontal when dry and float up when wet.
2. When the bottom float goes dry, the input solenoid (INSOL) is opened and one second later, the Recirculation
Pump (PUMP) turns on.
3. When the top float becomes wet, a Flush Cycle commences and then the System shuts off until the bottom float
goes dry again.
Flush Cycle (flush cycle consumes only a couple of quarts of pure water):
1. As the system is running, a periodic sequence of flushes is performed.
2. When the top float gets wet, or every 8 hours of uninterrupted operation, the flush cycle is initiated.
3. After the flush cycle, the system shuts down if the tank is full or pauses for an hour to let the pure water soak the
membrane before continuing.
