WARNING: IF PERMEATE BACK PRESSURE EXCEEDS 60 PSIG (4.1 BARG) MACHINE
DAMAGE MAY OCCUR.
WARNING: INSTALLING A CHECK VALVE WILL PREVENT REVERSE FLOW THROUGH
THE MEMBRANE ELEMENT WHEN THE MACHINE IS NOT IN OPERATION. REVERSE
FLOW, WHEN THE MACHINE IS NOT IN OPERATION, CAN SEVERELY DAMAGE THE
MEMBRANE ELEMENTS.

2.8. Electrical

This RO machine requires two supply voltages; the control voltage and the pump
motor voltage.
2.8.1.

Single-Phase Electrical

The control voltage can be connected to either a 115 VAC, 60 Hertz or 220 VAC, 50
Hertz single-phase power supply. The RO control circuit should always be installed on
at least a 15 Amp, single-phase dedicated circuit. Reverse osmosis machines with
115 VAC, single-phase control voltage include an eight-foot (2.4 m) cord which plugs
into a three-prong grounded receptacle. All machines shipped with a 220 VAC, single-
phase control circuit are shipped with an eight-foot electrical cord, but customers
must provide electrical plug.
2.8.2.

Three-Phase Electrical

The three-phase pump motor requires a 15 AMP dedicated circuit. Always verify
correct voltage and Amp rating by checking voltage tag on the starter box or by
checking electrical specifications on the pump. The motor is wired for 460 Volts, 60
Hertz, three-phase voltage from the factory (Figure 5, Three-Phase Allen Bradley
Motor Starter). The pump motor can be rewired to 208 or 230 Volts. If this is done, a
wiring change must be made internally in the pump motor and a higher amperage
relay and starter may need to be installed. All field wiring must comply with
applicable local and national electrical codes.
After checking the voltage tag on the motor starter to ensure the available voltage
and amperage are correct, connect the provided three-phase power to the motor
starter (Figure 5). This can be done by connecting the three phase power to the top of
the starter relay terminals: L1, L2, and L3. A separate, fused disconnect for the motor
wiring with proper protection for the Horsepower and Amp draw of the motor is
recommended. All field wiring must comply with applicable local and national
electrical codes. See Figure 5 for three phase Allen Bradley Starter Hook-Up.
