It is also 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 the control devices to distribute this fixed flow amount. The pres- sure gauge is an indicator of applied membrane element pressure a the flows set by the valves
8.Press the Fill Button on the OIT so it is in the ON position. Water should begin to flow through the machine at this point, but the pump will not start. Allow the machine to fill for ten (10) minutes.
9.As your machine is filling check for leaks and repair as needed.
10.Turn the ON/OFF switch, located on the High Voltage Enclosure, to the ON posi- tion.
11.Energize the power source to the motor starter. The pump should not operate at this point.
12.Check the rotation of the
12a Press the RO button so it is in the ON position.
After the minimum inlet pressure [0.8 bar (11.6 psi)] is established and maintained for six (6) seconds, the

The motor should rotate clockwise while looking at the motor end of the high- pressure pump. If the motor is not rotating clockwise, change any two of the three leads in the motor starter and recheck rotation.
WARNING: ALWAYS TURN POWER OFF TO CHANGE ANY WIRING.
CAUTION: Operation of the pump backward, even for a short time, can cause damage to the pump.
13.Press the RO button so it is in the ON position. The
14.As the machine is operating, watch the primary and final pressure gauges on the instrument panel. The machine is designed to operate at approximately 7.6 bar (110 psi).
NOTE: Do not allow the pressure to exceed the maximum boost pressure (Pmax) specified for your machine model (Table 1.2). If the pressure exceeds Pmax, open the concentrate and/or recycle control valves until the pressure gauge shows Pmax or less.
