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 controller on/off switch is in the off position.
3. Close the pump discharge completely then open it one turn. Note: All valves on this unit
turn clockwise to close.
4. Install four 20" five micron filter cartridges in the prefilter housing.
5. Open the reject control valve completely by turning it counterclockwise.
6. Close the reject recycle control valve completely by turning it counterclockwise.
7. Open the feed water shutoff valve installed in step III-B-1 above.
8. Engage the safety switch or disconnect (installed in step III-C-1 above) to apply electrical
power to the RO system.
9. Move the controller on/off switch to the on position. Move the switch back to the off
position after the pump starts and look at the motor fan as the pump stops to determine if the
pump rotation is correct. The fan should rotate in the direction indicated by the arrows on the
pump. Continue with the startup if the pump is rotating in the proper direction. If the
pump rotation is backwards, reverse the rotation by shutting off the power and swapping any
two of the three power lines connected in step III.C.3 above
10. Turn the system on and allow the product and reject water to go to drain for 15 minutes.
11. Adjust the reject control valve, the reject recycle control valve and the pump discharge valve
until the desired flows are achieved. Closing the reject valve increases the recycle and
product flow and decreases the reject flow. Closing the reject recycle valve increases the
reject and product flow and decreases the recycle flow. Opening the pump discharge valve
increases all of the flows. See the temperature correction table in the appendix to determine
the flow rates for different operating temperatures.
12. Allow the product water to flow to drain for 30 minutes.
13. 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.
14. Restart the system and record the initial operating data using the log sheet in the next section.
15. See the controller section for detailed information about the controller.
