and location must be determined by the installer. Check the pump motor nameplate for the
amperage draw at various voltages to determine the wire size required.
4. Do not apply power to the RO unit at this time.

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 pump discharge valve (Figure 2-1, item D) is open.
3. Install a 20" five micron filter cartridge in the prefilter housing. (Figure 2-1, item K)
4. Open the reject control valve completely (Figure 2-1, item B) by turning it counterclockwise.
Close the reject recycle control valve completely (Figure 2-1 item C) by turning it clockwise.
5. Open the feed water shutoff valve installed in step III-B-1 above.
6. Manually open the inlet solenoid valve (figure 2-1, item L) by turning the white lever located
near the valve outlet.
7. Water will flow through the system and to drain through the reject flow meter (Figure 2-1, item
H).
8. Manually close the inlet solenoid valve after the air has been purged from the system, or after
10 minutes, whichever occurs first.
9. Close the pump discharge valve half way. (Figure 2-1, item D)
10. Engage the safety switch or disconnect (installed in Section 3.3, step 1, above) to apply
electrical power to the RO system.
11. Press the
On/Off
button on the controller. When the pump starts, press and hold the
On/Off
button to turn off the pump and look at the motor fan as the pump stops to determine if the
pump rotation is correct. See the controller section for more details. The fan should rotate in
the direction of the rotation arrow located on the pump. Continue with the startup if the pump
is rotating in the proper direction. If the pump is rotating backwards, change the rotation by
disconnecting the power and reversing any two of the wires on the power inlet. Verify proper
pump rotation before continuing.
12. Turn the system on.
13. Adjust the reject control valve(s) (Figure 2-1 items B & C) and the pump discharge valve
(Figure 2-1 item D) until the desired flows are achieved. Closing the reject valve increases
the product flow and decreases the reject flow. Opening the pump discharge valve increases
both the reject flow and the product flow. See the flow rate guidelines and Temperature
Correction table in the Appendix to determine the flow rates for different operating
temperatures.
14. Allow the product water to flow to drain for 30 minutes.
15. Turn off the system and connect the product line to the point of use. (Figure 2-1 item I) The
product water line should never be restricted. Membrane and/or system damage may occur
if the product line is blocked.
16. Restart the system and record the initial operating data using the log sheet in the next section.
