6. Turn the ON/OFF button on the machine ON. System will open allowing water
to flow through the machine to the drain through the permeate and concen-
trate CIP valves.
Let the machine run to drain for 5 - 10 minutes. This provides a wet start-up
of the pump and removes any air in the system.
7. Turn the ON/OFF button on the machine to the OFF position.
8. Re-energize the pump power and trigger the ON/OFF button on the machine
to check rotation of the pump motor. Observing from the back of the pump
motor, pump rotation should be clockwise. If rotation is wrong, de-energize
the pump voltage from the source and switch any two of the three-phase
wires coming in on top of the three-phase starter. Re-energize the pump volt-
age and re-check, to ensure correct rotation for the start-up and operation of
your machine.
WARNING: IF THE RO PUMP IS STARTED WITH INCORRECT ROTATION
(i.e., BACKWARDS), A NOTICEABLE DROP IN FLOWS AND
PRESSURES WILL RESULT. IF PUMP MOTOR OPERATES BACK-
WARDS FOR ANY LENGTH OF TIME, PUMP DAMAGE MAY
RESULT.
After correct rotation has been verified, you are now ready to start the
machine and set the flows and pressures.
9. With the recycle and concentrate orifices still two (2) turns open and ade-
quate feed water available, start the machine by turning the ON/OFF button
to the ON position.
10. As the pump starts to build pressure, begin to adjust the orifices in the follow-
ing manner: start by slowly closing the concentrate orifice while slowly open-
ing the recycle valve.
Primary Pressure for Normal Operation at 77°F (25°C)
E4-Series: 220 psi (15.2 bar) at 77°F (25°C)
EZ4/E4LE-Series: 115 psi (7.9 bar) at 77°F (25°C)
While you are doing these valve adjustments, to obtain correct flows and
pressures, observe the primary or pump pressure. The pump pressure, while
adjusting the orifices, should never operate outside of these ranges:
E4-Series Range: 190 - 275 psi (13.1 - 19.0 bar)
EZ4/E4LE-Series Range: 100 - 140 psi (6.9 - 9.6 bar)
