START-UP PROCEDURES
INSTALLATION FOLLOW-UP
1.
Visually inspect the water connections.
2.
Be sure filter cartridges have been installed.
3.
Confirm connection to the proper power source.
NOTE: The membrane element(s) will have been installed
in the system during the final testing procedures unless
other
arrangements
have
been
made
with
the
manufacturer.
PRETREATMENT FOR THE RO SYSTEM
A water analysis of your feed water should have been
performed to determine what type of pretreatment may be
required. See Feed Water Parameters for this system before
operating this system.
DIVERT PRODUCT WATER TO THE DRAIN
During the initial start-up of the system, it is important to
divert all of the product water to a wastewater drain for
approximately 30 to 60 minutes. Membrane elements are
treated with a preservative solution and should be thoroughly
rinsed clean before water is retained for use. This can be done
either by installing a 3-way valve in the product water line or
by diverting your product water line to drain. Do not connect
the product water line to a storage tank at this time.
FLUSH THE SYSTEM
Standard System With Manual Flush
- Open the inlet feed
water shut-off valve and allow the system to fill with water.
Press the pressure relief button to release the air from the filter
housings, and open the manual flush valve.
Plug the power cord into the wall outlet. The inlet solenoid
valve will open, and the pump will start. When the system is
turned on, the solenoid valve automatically opens. The valve
will close when the system is turned off. The system will only
start with sufficient feed water flow and pressure (minimum
35 PSI). Low inlet feed water flow and low pressure can result
in damage to the system.
Allow the system to run approximately 3 to 5 minutes to bleed
all trapped air and to flush the membrane element. Then, close
the manual flush valve.
System With Optional AutoFlush Feature
- If your system is
equipped with the optional Automatic Timed Flush feature,
the manual flush valve will be eliminated. In place of the
manual flush valve is a Flush solenoid valve. The solenoid is
wired to the electrical enclosure and is pre-set so that a one-
minute flush will occur every time the system goes into
operation. A one-minute flush will also occur every 2 hours
the system runs constant.
Open the inlet feed water shut-off valve and allow the system
to fill with water. Press the pressure relief button to release the
air from the filter housings. Plug the power cord into the wall
outlet and the system will start with a one-minute automatic
flush. You may want to repeat this step to insure the
membrane element is thoroughly rinsed. After the flush cycle
has stopped, proceed to the next step.
ADJUST THE SYSTEM OPERATING PRESSURE
Adjust the system pressure regulator so that the system
pressure gauge reads 150 PSI. Turn the pressure regulator
clockwise to increase the pressure, and counterclockwise to
decrease the pressure.
This Reo-Pure System was designed to operate at 50%
recovery. The gallons per day of product water produced will
vary based on the feed water TDS, feed water temperature,
and the backpressure on the system.
Measure the amount of time in seconds it takes for the system
to produce 1 quart of product water. Use the following
formula to calculate the gallons per day: 21,600 divided by the
seconds it took to produce one quart, equals the gallons per
day.
CHECK THE INLET LOW PRESSURE SWITCH
The inlet feed water low-pressure switch is preset at the
factory. Its purpose is to prevent damage to the system if there
is inadequate feed water flow or pressure.
This step is to verify that it is functioning properly. Slowly
decrease the inlet feed water supply by closing the manual
feed water shut-off valve, while watching the pre-filter outlet
pressure gauge. If the system shuts down when the pressure
drops to approximately 15 PSI, then the inlet pressure switch
is functioning correctly. If it is not functioning correctly, refer
to the Section of this manual on System Pressure Switches.
PURGE THE SYSTEM
Allow the system to operate approximately 30 to 60 minutes
diverting the product water to drain. Once all of the membrane
preservative is flushed from the system, product water may be
retained for use.

IMPORTANT MAINTENANCE
– Depending on the
quality of your feed water, we recommend the manual
flush valve be opened at least once a week for 3 to 5
minutes to rinse the membrane element.
IMPORTANT
– Frequently check the system for any
leaks that may develop.
CAUTION
– Never allow the Reo-Pure
system pressure to exceed 180 PSI
