OPERATIONAL DESCRIPTION
(how the system functions)
1. The incoming feed water (1/4" Black line) is passed through a 0.5 micron MicroTek™ Sediment Filter. This filter is
required to remove excess turbidity (particulate matter) that may cause the carbon block filter to become fouled.
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 filters are our Mega MaxCap DI™ cartridge followed by our Enduro DI™ cartridge. These two
cartridges remove the remaining silicates, phosphates, and nitrates that make it past 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 becomes dry, the input solenoid is opened and one second later, the Recirculation Pump turns on.
3. When the top float becomes wet, a Flush Cycle commences and then the System shuts off until the bottom float
becomes dry again.
Flush Cycle (flush cycle consumes only a couple of quarts of pure water):
1. As the system is running, a periodic flush is performed.
2. When the top float becomes 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.
DUAL-PROBE TDS METERS

assumes no responsibility for water damage due to leaks. It is
the user’s responsibility to determine that the system is leak-free.
The Performance Plus™ UHE system comes equipped with two (2) dual-probe
TDS meters. Use the selector switch on the meter to read the TDS from each
of the probes.
The readings from the Left-Hand Meter will be used to monitor the quality
(percentage of rejection) of the RO membrane. (See REVERSE OSMOSIS
MEMBRANE DIAGNOSTICS on page 13.)
The reading from the Left-Hand Meter will be used to monitor the state of the
Mega MaxCap™ DI cartridge and the Enduro DI™ cartridge. Set to “OUT”, it
will also show the TDS of the product water.
