Control Box and Functions
1) When the unit is plugged in and switched on, the flush timer is activated. The unit will start in flush
mode every time the unit is turned off and back on with the switch.
2) This flush timer runs the unit in flush mode for approximately two minutes. Then, the timer allows
about two hours between flush cycles.
3) Once the unit is powered, the black leg of the control circuit (see the supplied electrical schematic)
is energized and the signal runs down to the pressure switch as described in the Solenoid Valve
section in this document.
 If the water is on and the pressure is higher than 7 PSI, the pressure switch closes and the
red circuit is energized.
 The flush relay, which looks like an ice cube in the box, and the unit will energize and open the
following: the inlet solenoid valve, (the orange circuit), the flush solenoid valve (yellow circuit),
and begin the time delay (orange again).
 After about 12 seconds the pump motor starts again.
4) After the pump motor starts, the water is forced into the membrane, and since the flush solenoid
valve is open the following will be observed: a large quantity of water flowing out of the reject hose,
low pressure on both gauges and little, if any, water flows in the flow meters.
Note: This condition should last about two minutes.
5) After the unit comes out of flush mode, the flush relay is de-energized and the flush circuit (yellow)
and the run circuit (orange) turn off.
Note: As long as the pressure switch is closed, the signal then runs to the float plug receptacle.

Note: If the float, as described in the Quality Sensor Light section in this document, is plugged in
and the float is hanging down, then the pressure switch closes and the run (orange) circuit
is energized and the unit makes RO water.
6) If the RO unit does not run, here are some things to check.
a. Is the system plugged into a live electrical circuit?
 Check the breaker and check the receptacle with a volt/ohm meter.

Note: Is the water on? Is there flow to the machine? The pressure switch will keep the system
from running without water to protect the pump and membrane.

Note: It is possible that the water faucet is open, but there is a plugged carbon filter tank.
 Check the flow IN and OUT of the carbon tank.
b. Is the float plugged in?
Note: If the float is unplugged the unit thinks the tank is full, and turns off the unit.
c. Is the tank full?

Note: The float switch is there to keep the unit from over flowing.
7) If the RO is turned on, but only runs in flush mode.
a. Is the tank full?
Note: The float is to keep the machine from overflowing the storage tank.
b. Is the float plugged in?
Note: If the float is unplugged the unit thinks the tank is full, and turns off the unit.
