1. 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.
2. Attach the feed water pipe to the inlet of the machine.
3. Check for leaks at all connection points.
4. 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.
When the machine is off, there should never be flow

5. Attach tubing from permeate and concentrate outlet points, and run the tubing to
drain.
6. Ensure that you have made provisions for both voltages required to operate
y
our
machine. The machine requires two power sources: (1) the high voltage for the motor
operation, and (2) the control circuit power supply. The motor electrical service must be
field-wired directly into the motor starter on the machine. Bring your motor service
wiring to the 3-pole contacts on the motor starter. Check the voltage label to ensure
that you have brought the correct voltage to the starter.
7. Be sure the power to the motor starter is de-energized.
