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
SpectraPure® Inc.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.

1. CHOOSING THE BEST MOUNTING LOCATION:
LIGHT SOURCE: Algae is more likely to thrive inside clear housings when exposed to ultraviolet light and other sources
like metal halide lighting. Avoid installing the unit in bright light or direct sunlight.
EXTREME TEMPERATURES: The unit MUST be kept out of areas that are subject to extreme temperatures like freezing
or temperatures greater than 113° F (45° C)
FRESH WATER RESERVOIR: Mount system in an area that will have enough room for a small trash can or reservoir. This
Fresh Water Reservoir is to be used for the Flush Cycle. (Reservoir needs to hold at least 10 gallons)
ELEVATION FOR SYSTEM: When mounting your UHE, make sure it is elevated above your fresh water reservoir:
2. TOOLS RECOMMENDED FOR INSTALLATION:
3. INTRODUCTION TO PUSH FITTINGS:
Push fittings are similar to a Chinese finger trap toy. In order to release its grip from tubing,..
- Firmly depress and hold the push fitting collar down with your thumbnail.
- While the push fitting collar is depressed, pull the tubing straight out of
the push fitting. Once the tubing is removed, release the collar.
- Adjustable Wrench - Phillips Screw Driver
- Sharp X-acto®Knife - Trash Barrel or Reservoir
- Open End Wrench(s - Optional Ball Valve or Float Valve. (as shown above)
- Electric Drill - Optional Delivery Pump (as shown above)
- 5/8” Drill bit
-13/16” Drill bit

SETUP PROCEDURES
STEP 1: INSTALLATION OF THE HIGH & LOW FLOAT SWITCHES:
A. Install both the High and Low Floats onto an open container, such as a Rubbermaid
®
trash can. The floats
can be mounted by drilling a 5/8" hole. The white washer should be located on the inside of the reservoir.
(The High Float shuts down the system, while the Low Float turns the system on).
B. Connect the floats to the “Y” adapter.
C. Attach the 3-pin connector on the float switches to the UHE CONTROL MODULE. (See image on page 5)
NOTE: Floats are to be mounted horizontal when dry and float up when wet. In most instances we recommend
locating the low float approximately halfway down your reservoir. DO NOT OVERTIGHTEN when
installing the floats.
NOTE: Floats must be installed in the FRESH WATER storage container.
This system MUST be connected to the floats to operate properly.
Failure to install the pure water flush connection for this unit will void any warranty.
STEP 2: CONNECT BULKHEAD FITTING:
(Bulkhead Fitting MUST be installed on the same container as the floats. See Diagram above.)
NOTE: DI input Float Valve
should be mounted
higher than the High
Float but o󰀨set to one
side so it won’t interfere
with the High Float.
3/8" BULKHEAD FITTING:
Use a paddle bit and carefully drill a 13/16"
hole for installation at the bottom of the
reservoir (below the low level float).

STEP 3: INSTALL THE FLOAT VALVE near the top of the reservoir. This will act as a fill valve and as a safety backup
float. The Float Valve should be mounted higher than the High Float and offset to one side so that it does not
interfere with the High Float when the reservoir is being filled.
a. Drill a 1/2” hole near the top of your reservoir.
NOTE: If you are installing the Float Valve onto an acrylic tank we recommend using a new Fostner Bit to reduce
the chance of cracking the acrylic.
b. (Refer to Diagram below) Remove the Compression Nut from the float body.
c. Insert the 1/4” Blue Tubing into the 1/2” Compression Nut with the threads towards the end of the tube.
d. Unscrew and remove the remaining nut from the float body.
e. Insert the float body and washer into the 1/2” hole and tighten the nut, which securely tightens the float to
the tank wall.
f. Push the Compression Nut towards the end of the tubing and screw the Compression Nut back onto the float
body.
g. To tighten, use one 1/2” wrench on the flats of the plastic threads and another 1/2” wrench on the Compression
Nut.
STEP 4: Connect the 1/4” Black Line to the cold water line by using either the garden hose adapter, which is provided
with the system, or a Feed Water Adapter.
