8.
Once all the desired flows are set, allow the system to run for approximately 30 minutes, and then record the
following measurements using the units gauges (U) and your instruments (I):
a. Feed Water Temperature, °F (I)
b. Feed Water SDI (I)
c. Feed TDS, ppm (I)
d. Inlet Pressure, psig (I)
e. System (pump outlet) pressure, psig (U)
f. Waste Flow, gpm (U)
g. Product Pressure, psig (I)
h. Product flow, gpm (U)
i. Feed Flow (=Waste Flow + Product Flow)
j. % Recovery (see
k. % Rejection (see

9.
Turn the power OFF. Connect the product tubing to the service plumbing.
10. Apply power to the unit, and then press the RUN NOW button.
11. Test the operation of the inlet pressure switch by closing the inlet water supply valve. The unit should shut down
the pump and inlet valve immediately. The POWER and READY lights should remain on.
CAUTION!
12. Open the inlet water supply valve, apply power, and press the RUN NOW button. The unit should begin produc-
ing RO water.
13. If connected, test the storage tank level control shutdown and the pretreatment lockout function.
Controller Behavior when Power First Applied
1.
When main power is first applied to the CP Plus controller, the POWER LED is lighted.
2.
If pretreatment lockout is not in effect and the storage tank is not full, the READY LED is lighted.
3.
The controller will first wait for a one-hour delay. To immediately start the system, apply power and then
press the RUN NOW button on the bottom of the controller. The controller opens the RO inlet solenoid valve.
NOTE
The RUN NOW button will not work if any of the following five events are occuring:
•
Tank Full switch is OPEN (open status indicates the water level in the tank has reached the TANK FULL
state)
•
Pretreatment lockout switch is OPEN (open status indicates a device upstream of the RO is requesting that
the RO not be in service)
•
Loss of electrical power
•
Loss of inlet pressure
•
Two-hour continuous make-water timer expiration
4.
Wait for an additional one-minute period. The INLET VALVE OPEN LED is lighted. During this period, feed
water under line pressure enters the RO, passes through the pump, flushes through the upstream (feed water
side) of the membranes, and then passes to the drain.
5.
Because the line pressure is expected to be fairly low (lower than 100 psi) very little permeate water is created
during this flush time. Instead, any high-TDS water on the membrane feed side is flushed to drain.

If the unit does not automatically shut down, turn the unit power switch OFF imme-
diately to prevent pump damage. Disconnect electrical power source, then check the
wiring and replace the switch, if necessary.
