Introduction
It is your responsibility to read and understand the contents
of this manual prior to installation and use of this equip-
ment.
This manual contains the information you will need to
install, operate and maintain the ULTROpure Reverse
Osmosis Systems, Cat. Nos. D6821, D6822 & D6823.
Please take a few minutes to familiarize yourself with the
hardware before beginning installation.
Warning
This device is to be used only with
water feeds and specified pretreatment
chemicals determined by a H20 Select
water analysis. Sanitizing/cleaning
agents must be used in compliance
with instructions in this manual. ailure
to comply with the above could result
in explosion and personal injury.

7
Precautions Before Installation
It is the userʼs responsibility to assure that an adequate
water analysis has been performed to determine feedwa-
ter composition and pretreatment requirements before
operation of the ULTROpure. This is a condition of your
One Year Limited Warranty (see back cover). Operation
of the ULTROpure without prior determination of the
feedwater composition can destroy reverse osmosis
membranes.
We provide a free water analysis service called H20
Select and will make pretreatment recommendations
where necessary. If you did not have a water analysis
performed before the purchase of this equipment, you
will find a sampling kit with the ULTROpure. ollow the
instructions included with the kit and return the sample to
us.
Depending on the membrane selected for use in your
ULTROpure, certain conditions (refer to the Equipment
Specifications section on page 17.) must be established
and maintained before and during operation. The user
should pay particular attention to the requirements for
residual chlorine and pH specifications. In some installa-
tions, pH adjustment is required to prevent hard scale
formation on the membrane surface, or membrane hy-
drolysis. In these cases, the adjusted pH should be 6.25.
Routine use of the ULTROpure requires weekly monitor-
ing of pH and/or residual chlorine levels. This is due to
seasonal variations in water supplies and changes in
processing by local municipalities which can affect these
levels.
Residual chlorine and pH can be easily measured by
using inexpensive kits available from your laboratory
supply dealer. An Operating Record Log Sheet is provid-
ed on page 31 of this manual for recording these mea-
surements. You should make additional copies of the log
sheet for future use before entering any information.

System Location
The ULTROpure should be mounted at a height that
allows for convenient operation, viewing of the controls
and access to the front of the unit for routine service. A
6-inch minimum clearance is recommended below the
ULTROpure.
Proper ventilation of the ULTROpure requires at least 12
inches of free access to the right and top of the unit. Left
side clearance should accommodate the required plumb-
ing connections. Leave at least 16 inches in front of unit
for top cover and front cover removal.
Mounting
Mount the ULTROpure by the following steps:
A. Locate the angle iron wall bracket and use
this as a template for locating holes in the
wall. As a guide, the center line of the mount-
ing holes in the angle iron wall bracket should
be approximately 13 1/2 inches below eye
level.
B. Drill holes, sized to the selected fasteners, in
the wall.
C. Mount the angle iron wall bracket, making
sure that it is level prior to tightening the fas-
teners. The locating pins should be facing up.
D. Using the bottom edge of the angle iron wall
bracket included with the ULTROpure as a
guide, scribe a line on both sides of the brack-
et 13 1/8 inches above the wall bracket.
These lines will be used as reference points
to verify proper engagement of the two mating
brackets.
E. Install the rubber pads over the locating pins
on the angle iron wall bracket. The rubber
pads are in the plumbing hardware package.
Note
If you are installing additional
equipment with the ULTROpure, such
as a Barnstead NANOpure, refer to
the individual ownerʼs manual for
space requirements before installing
the ULTROpure System. If you are
using other storage reservoirs, refer to
page 26 for additional information.
Warning
Do not mount the ULTROpure directly
over equipment that requires electrical
service. Routine maintenance of this
unit may involve water spillage and
subsequent electrical shock hazard if
improperly located.
Caution
Do not connect unit to electrical service
until instructed to do so.
Note
The mounting holes in the angle iron
wall bracket are 16 inches on center,
per standard construction practices,
and will accommodate 3/8" fasteners.
Caution
Wall composition, condition and con-
struction, as well as fastener type must
be considered when mounting this unit.
The mounting surface and fasteners
selected must be capable of supporting
a minimum of 350 pounds. Inadequate
support and/or fastener may result in

Initial startup of the Barnstead ULTROpure will require
the following customer-supplied items to set optimum op-
erating parameters:
pH meter or pH test kit.
Test kit for determining residual chlorine.
Refer to your water analysis printout and locate the rec-
ommended recovery rate for your unit. You will need to
set the ULTROpure valving for this specific recovery. If
you cannot find this analysis, DO NOT PROCEED UR-
THER. Refer to “Precautions Before Installation” in the
Installation section of this manual.
Set the ULTROpure recovery as follows:
A. Open the reject valve 3 full turns from the
closed position. This valve is located on the
top of the prefilter and is accessed by opening
the door in the front of the ULTROpure.
B. Open the customer supplied feedwater supply
shutoff valve. Check for leaks and correct, if
necessary.
C. Install the Storage Interlock Jumper plug, sup-
plied in the ULTROpure plumbing hardware
package, into the Storage Interlock on the
right side of the ULTROpure.
D. Connect the power cord to the power entry
module on the right hand side of the unit and
to an appropriate power supply.
E. Press the “Power” button on the ULTROpure
control panel.
. After the high pressure pump has started,
adjust the recycle valve until the membrane
pressure gauge is reading 150 psig.
G. Check for leaks and correct if necessary.
Operation
Caution
Never restrict the flow of product water
from the ULTROpure. Restricting prod-
uct will destroy the membrane.
Note
Be sure that both Reject and Product
lines are routed to drain.
Note
Each time the “Power” button is
pushed, built-in time delays allow the
feedwater to fill the system prior to
starting the high pressure pump.
Ignore the digital display readings on
the % Rejection Monitor as you per-
form the preceding step (Step E).
Descriptions and explanations of the
meter display start on page 20. It is
not necessary to understand the moni-
tor display at this time.

20
H. Allow the ULTROpure to operate for at least 30
minutes to purge air from the membrane.
I. After the 30-minute purge, turn the recycle valve
until the membrane pressure increases to 200
psig. Allow 5 to 10 minutes for the system to
stabilize. Readings on flow meters are taken at
the indented point of the flow indicator.
J. Note the reading on the Product low Meter.
Enter this flow rate in the Operating Record Log
Sheet under “Initial Start-up.”
K. Refer to Table 3 and find the multiplication factor
which corresponds to the recommended recov-
ery given on your H20 Select water analysis.
Multiply the product flow rate measured in Step
J by this factor to find the required “Reject” flow
rate.
Example:
• Measured product flow rate = 400 ml/min.
• Water analysis recommends 40% maximum re-
covery.
• Multiplication factor for 40% recovery is 1.5.
• 1.5 (400) = 600 ml/min. reject flow rate required.
L. Now note the reading on the Reject low Meter.
If this rate is higher than the one you calculated,
do the following:
• Too High—Open the recycle valve until the
membrane pressure gauge is reading 180 psig.
Then close the reject valve to restore pressure
to 200 psig.
Note
Initial startup may cause a shutdown
condition (because of low pressure)
until the system is purged. The elec-
tronics allow for a restart prior to shut-
down. When the ULTROpure senses a
low pressure situation, it will wait 30
seconds---, then attempt a restart. It
will shut down if the unit senses low
pressure the second time. Should a
shutdown condition occur while you
are performing this startup, shut the
ULTROpure off and restart. If the shut-
down condition continues after the
system has been purged 3 to 4 times,
check to be sure that there is ade-
quate feedwater pressure at the
ULTROpure feedwater inlet (Refer to
Technical Characteristics). If adequate
pressure is available, close the reject
valve 1/2 turn and restart the unit.
Note
Check to be sure that water is flowing
from both the reject and product lines.
This can be accomplished by observ-
ing the flow meters. If no water is com-
ing out of the reject line, open the
reject valve until water flows out.
Product water generally takes a few
minutes after startup to completely fill
the product line.
Note
The flow meter is read at the indented
portion of the flow indicator. Before
taking the following flow rate readings,
be sure that the membrane pressure
gauge is reading 200 psig. THIS IS
IMPORTANT.
