STEPS

Re-check the function and integrity of your pretreatment equipment.
Ensure that your water softener, activated carbon filters and iron filters
(where applicable) have been leak-checked, backwashed, and thoroughly
rinsed for service before starting up your RO unit.

Attach the feed water pipe to the inlet of the machine.

Check for leaks at all connection points.

Turn ON the feed water gradually and check for leaks in the inlet piping.
No flow should go through the machine while the power is OFF and the
inlet solenoid is in the closed position.

NOTE: When the machine is OFF, there should never be flow through

the machine. Flow through the machine when it is OFF can ruin
the membrane elements, and the inlet solenoid must be repaired.

Attach tubing from permeate and concentrate outlet points and run the
tubing to drain.

Ensure that you have made provisions for both voltages required to oper-
ate your machine. The machine requires two power sources: (1) the high
voltage for the motor operation, and (2) the control circuit power supply.
The factory provides the 110 VAC (or 220 VAC 50 Hz) power cord need-
ed for the control circuit. The motor electrical service must be field-wired
directly into the motor starter on the machine. Bring your motor service to
terminals labeled “T” on the motor starter. Check the voltage label to
ensure that you have brought the correct voltage to the starter.

Be sure the power to the motor starter is de-energized.

With the machine ON/OFF switch in the OFF position, plug in the facto-
ry supplied 110 VAC (or 220 VAC 50 Hz) power cord.

Open your concentrate and recycle flow control valves two complete
turns. These valves are positioned on the flow control center of the
machine. This piping is located on the left section of the machine, near
the membrane element housings. The flow control center features a con-
centrate flow control valve, a recycle flow control valve, and a pressure
gauge sensor point piped into the panel-mounted pressure gauge.

NOTE: The Autoflush valve is positioned in this flow control center.

The proper adjustment of these valves is critical to the operation of the RO
machine. The concentrate valve determines the amount of rejected water
leaving the machine, and creates the operating pressure shown on the
pressure gauge. The recycle valve returns unused reject flow back into the
