The proper adjustment of these valves is critical to the operation of the RO
machine. The concentrate valve determines the amount of rejected water
leaving the machine, and creates the operating pressure shown on the
pressure gauge. The recycle valve returns unused reject flow back into
the inlet stream to the RO pump.
It is important to balance the operating pressure and the respective flows
of these valves, to ensure that your machine is operating correctly. It is
important to understand the relationship of these two valves, the pressure
gauge, and your RO pump. The pump has a fixed amount of flow
produced, and the valves are control devices to distribute this fixed flow
amount. The pressure gauge is an indicator of applied membrane
pressure, at the flows set by the valves.
10. Turn the ON/OFF switch to the ON position. Water will begin to flow
through the machine at this point but the pump will not start. Allow the
machine to operate in this manner for 10 minutes, to purge the air out of
the machine.
NOTE:
The high-pressure pump should not be operating at this time.
11. As your machine is filling, check for leaks and repair, as needed.
12. Turn the ON/OFF switch to the OFF position.
13. Energize the power source to the motor starter. The pump should not
operate at this point.
14. Check the rotation of the high-pressure pump by briefly turning the
ON/OFF switch to the ON position, as you look at the motor, or coupling
shaft. The motor should rotate clockwise if you are looking down on the
rotor motor end of the high-pressure pump. If the motor is not rotating
clockwise, change any two of the three leads (for 3-phase) into the motor
starter and recheck rotation. Always turn the power off to change any
wiring.
CAUTION:
Operation of the pump backwards for even a short time can cause damage to the
pump.
