4. Do not apply power to the RO unit at this time.
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. Verify that the pump discharge valve (Figure # 1 item C) is open.
4. Install a 20" five micron filter cartridge in the prefilter housing. (Figure #1 item I)
5. Open the reject control valve completely (Figure # 1 item B) by turning it counterclockwise.
Close the reject recycle control valve completely if the reject recycle option is included.
6. Open the feed water shutoff valve installed in step III-B-1 above.
7. Manually open the inlet solenoid valve (figure #1 item J) by turning the white lever located
near the valve outlet.
8. Water will flow through the system and to drain through the reject flow meter (figure # 1
item G).
9. Manually close the inlet solenoid valve after the air has been purged from the system, or after
10 minutes, whichever occurs first.
10. Close the pump discharge valve half way. (Figure # 1 item C)
11. Engage the safety switch or disconnect (installed in step III-C-1 above) to apply electrical
power to the RO system.
12. 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. If the CI 1000 Controller is included (controller option # 3), put the
key switch in the on position and press the start / stop button to turn the pump on and off.
There is a 10 second delay before the pump starts. See the controller section for more
details. The fan should rotate in the direction of the rotation arrow. 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.
(Figure #2 item #1) Verify proper pump rotation before continuing.
13. Turn the system on.
14. Adjust the reject control valve(s) (figure # 1 item B) and the pump discharge valve (Figure #
1 item C) 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.
15. Allow the product water to flow to drain for 30 minutes.
16. Turn off the system and connect the product line to the point of use. (Figure # 1 item # 2)
The product water line should never be restricted. Membrane and/or system damage may
occur if the product line is blocked.
17. Restart the system and record the initial operating data using the log sheet in the next section.
Note: See the controller section of this manual for more installation and operation
information
