INTRODUCTION
Your BT-Series system is a durable piece of equipment which, with proper care, will last
for many years. This User’s Manual outlines installation, operation, maintenance, and
troubleshooting details vital to the sustained performance of your system.
The test results which are included with this User’s Manual indicate your system’s
permeate (product) and concentrate (waste) test results.
If your system is altered at the site of operation or if the feed water conditions change,
please contact your local dealer or distributor to determine the proper recovery for your
application.
NOTE: IN ORDER TO MAINTAIN THE MANUFACTURER’S WARRANTY, AN
OPERATING LOG MUST BE MAINTAINED AND COPIES WILL NEED TO BE SENT TO
YOUR LOCAL DEALER OR DISTRIBUTOR FOR REVIEW.
NOTE: PRIOR TO OPERATING OR SERVICING THE REVERSE OSMOSIS
SYSTEM, THIS USER’S MANUAL MUST BE READ AND FULLY UNDERSTOOD. KEEP
THIS AND OTHER ASSOCIATED INFORMATION FOR FUTURE REFERENCE AND
FOR NEW OPERATORS OR QUALIFIED PERSONNEL NEAR THE SYSTEM.
SAFETY
The Safety section of this User’s Manual outlines the various safety headings used
throughout this manual’s text and are enhanced and defined below:
NOTE: INDICATES STATEMENTS THAT PROVIDE FURTHER INFORMATION AND
CLARIFICATION.
CAUTION: INDICATES STATEMENTS THAT ARE USED TO IDENTIFY
CONDITIONS OR PRACTICES THAT COULD RESULT IN EQUIPMENT OR OTHER
PROPERTY DAMAGE.
WARNING: INDICATES STATEMENTS THAT ARE USED TO IDENTIFY
CONDITIONS OR PRACTICES THAT COULD RESULT IN INJURY OR LOSS OF LIFE.
FAILURE TO FOLLOW WARNINGS COULD RESULT IN SERIOUS INJURY OR EVEN
DEATH.

DO NOT UNDER ANY CIRCUMSTANCE; REMOVE ANY CAUTION, WARNING,
OR OTHER DESCRIPTIVE LABELS FROM THE SYSTEM.
FEED WATER & OPERATION SPECIFICATIONS
Nothing has a greater effect on a reverse osmosis system than the feed water quality.
NOTE: IT IS VERY IMPORTANT TO MEET THE MINIMUM FEED WATER
REQUIREMENTS. FAILURE TO DO SO WILL CAUSE THE MEMBRANES TO FOUL
AND VOID THE MANUFACTURER’S WARRANTY.
OPERATING LIMITS
NOTE: HIGHER TDS AND/OR LOWER TEMPERATURES WILL REDUCE THE
SYSTEM’S PRODUCTION.
REJECTION, RECOVERY, & FLOW RATES
BT-Series reverse osmosis systems are designed to produce permeate water at the
capacities indicated by the suffix in the system’s name under the conditions listed
above. For example, the BT-1500 produces 1500 gallons per day of permeate water at
the listed operating test conditions.
The amount of total dissolved solids (TDS) rejected by the membrane is expressed as a
percentage. For example, a 98.5% rejection rate means that 98.5% of total dissolved

6
ENGF-106 REV. A 01/11 © 2011 AXEON Water Technologies
solids do not pass through the membrane. To calculate the % rejection, use the
following formula:
% Rejection = [(Feed TDS – Product TDS) / Feed TDS] x 100
Example:
98.5% = [(550-8.25)/550] x 100
NOTE: ALL TDS FIGURES MUST BE EXPRESSED IN THE SAME UNITS,
TYPICALLY PARTS PER MILLION (PPM) OR MILLIGRAMS PER LITER (MG/L).
BT-Series reverse osmosis systems are designed to reject up to 98.5% NaCl, unless
computer projections have been provided or stated otherwise.
The amount of permeate water recovered for use is expressed as a percentage. To
calculate % recovery, use the following formula:
% Recovery = (Product Water Flow Rate / Feed Water Flow Rate) x 100
Example:
50% = (1.04/2.04) x 100
NOTE: ALL FLOW RATES MUST BE EXPRESSED IN THE SAME UNITS,
TYPICALLY GALLONS PER MINUTE (GPM).
SYSTEM REQUIREMENTS & OPERATION GUIDELINES
PLUMBING
The membranes and high pressure pumps used on BT-Series systems require a
continuous flow of water with a minimum feed pressure of 35 psi, not to exceed 105°F.
FEED WATER CONNECTION
1. Locate the 1” FNPT Solenoid Valve feed water inlet.
(Figure 1A, Page 12)
2. Attach the inlet piping to the 1” FNPT Solenoid Valve feed water inlet.
3. Be certain that all of the components of the feed water are soluble at the
concentrations attained in the system.

7
ENGF-106 REV. A 01/11 © 2011 AXEON Water Technologies
NOTE: FEED LINE MUST BE MINIMUM 1/2” INCH.
PERMEATE (PRODUCT WATER) CONNECTION
Locate the 3/8” tubing labeled permeate and attach to storage tank. Ensure that the
permeate water can flow freely with no backpressure. Backpressure can cause
irreversible damage to the membrane elements. The 3/8” permeate line can be run to
the holding tank with PVC fittings, or other FDA approved materials. This is so the
material being used does not dissolve into the permeate water.
CAUTION THE PH OF THE REVERSE OSMOSIS PERMEATE WATER WILL
TYPICALLY BE 1-2 POINTS LOWER THAN THE FEED WATER PH. A LOW PH CAN
BE VERY AGGRESSIVE TO SOME PLUMBING MATERIALS SUCH AS COPPER
PIPING.
CONCENTRATE (WASTE WATER) CONNECTION
Locate the 3/8” tubing labeled concentrate and attach the tubing to a drain. Run the
concentrate line to an open drain in a free and unrestricted manner (no backpressure).
CAUTION: ANY RESTRICTIONS OR BLOCKAGE IN THE DRAIN LINE CAN
CAUSE BACKPRESSURE, WHICH WILL INCREASE THE SYSTEM’S OPERATING
PRESSURE. THIS CAN RESULT IN DAMAGE TO THE SYSTEM’S MEMBRANES AND
COMPONENTS.
ELECTRICAL
The motor used on the BT-Series systems is a carbonator motor. The motor is available
in 110/220 Volt 50/60 Hertz 1 Phase. Each BT-Series system is equipped with a 5 foot
electrical cord. 110V models are equipped with a plug.
Ensure that the electrical circuit supplying the system is compatible with the
requirements of the specific BT model you are installing.

ENGF-106 REV. A 01/11 © 2011 AXEON Water Technologies
NOTE: IT’S RECOMMENDED THAT A LICENSED ELECTRICIAN WIRE YOUR
SYSTEM IN ACCORDANCE WITH LOCAL AND NATIONAL ELECTRICAL CODES
(NEC).
WARNING: TO REDUCE THE RISK OF ELECTRICAL SHOCK, THE
INCOMING POWER SUPPLY MUST INCLUDE A PROTECTIVE EARTH GROUND.
BT-Series systems are typically controlled with a liquid level switch in a storage tank.
The liquid level switch turns the system on when the water level in the tank drops, and
off when the tank is full. Liquid level switches can be obtained by your local dealer or
distributor. If a liquid level switch is to be used, install it at this time.
PRE-FILTRATION
BT-Series systems are supplied with a 5 micron sediment filter and a 10 micron carbon
block. Change the cartridge once a month or when a 10-15 psi differential exists
between the two pre-filters. Ask your local dealer or distributor about Pre-Filtration
systems, if required.
NOTE: THE SYSTEM MUST BE OPERATED ON FILTERED WATER ONLY.
PUMP
The pump type used on the BT-Series systems is brass rotary vane pumps. These
pumps are also available as an option in stainless steel.
If any damage occurs to your system’s pump, a re-build kit may be available. Contact
your local dealer or distributor and inform them of your system and pump model.
MOUNTING
The free standing system should be bolted down in compliance with local regulation
standards or securely fastened.
MEMBRANE ELEMENTS
BT-Series reverse osmosis systems come pre-loaded with Thin Film Composite (TFC)
HF1 High Flow Low Energy membranes, unless otherwise specified. General
membrane element performance characteristics are listed on the next page.
