D. STARTUP
1. Verify that the pretreatment equipment is installed and working properly. Verify that no
free chlorine is present in the feed water.
2. Verify that the on / off switch is in the off position.
3. Install a 10" five micron filter cartridge in the prefilter housing.
4. Open the reject control valve completely (Figure # 1 item C) by turning it
counterclockwise.
5. Close the reject recycle control valve (Figure # 1 item D) completely by turning it
clockwise.
6. Open the feed water shutoff valve installed in step III-B-1 above.
7. Move the controller on/off switch to the on position.
8. Allow the unit to run for 15 – 30 minutes to flush the preservative from the membrane(s).
9. Adjust the reject control valves (Figure # 1 items C & D) until the desired flows are
achieved. Closing the reject valve increases the product flow and decreases the reject
flow. Opening the reject recycle valve decreases both the reject and product flow. See
the flow rate guidelines and temperature correction table in the appendix to determine the
flow rates for different operating temperatures.
Do not exceed 200 psi on the pump
discharge gauge (Figure #1 item F).
10. Allow the product water to flow to drain for 30 minutes.
11. Turn off the system and connect the product line to the point of use. The product water
line should never be restricted. Membrane and/or system damage may occur if the
product line is blocked.
12. Restart the system and record the initial operating data using the log sheet.
E. CONTROL FUNCTION
1. When the on / of switch is in the on position, the inlet valve opens and the pump runs. If
the product pressure switch is used then the pump will cycle based on the product water
pressure. The switch is factory set to cut off at 40 psi and cut on at 20 psi. Instructions
for adjusting the cut off and cut on pressures are located on the inside cover of the switch.
2. If the water pressure feeding the pump drops below 5 psi for more than 5 seconds, the
pump will turn off and the amber light on the control box will turn on. The controller
will automatically reset after 30 minutes and the pump will turn back on. Cycle the off /
auto switch to manually reset a low-pressure shutdown.
3. Autoflush – This is an optional feature that provides increased reject flow at startup and
for 2 minutes every hour. The timer is preprogrammed at the factory and should not be
adjusted.
