Measuring Motor Resistance
1. Disconnect all power by placing the safety disconnect switch in the open position.
2. Lockout and tagout the safety disconnect switch.
3. Verify the motor resistance between motor wires by measuring between L1 and L2
• The resistance should be between 1.4 - 2.0 ohms depending on the length of the cable.
4. Measure the motor resistance between L1 and L2 and motor ground.
• The resistance should be between greater than 700K ohms.
5. If all the readings are within specification, then remove any lockout/tagouts and perform the
PAX Water Mixer start-up.
Measuring AC Input Voltage
1. Power up the PAX Water Mixer.
2. Set the Multimeter to AC Volts. Place the probes across the incoming power.
• Verify that the voltage is between 110 - 120 VAC.
Measuring AC Input Current
1. Power up the PAX Water Mixer.
2. Set the multimeter to AC amp.
3. Clamp the current meter to each of the input power wires.
• Verify that the current is between 9.5 and 11.5 AC amps.
9. Recommended Maintenance Checks
NOTE:
There is no preventative maintenance required for the PAX Water Mixer.
1. Perform the PAX Electrical Checks (Section 8) annually to ensure that the PAX Water Mixer
is operating within specification.
2. Pull the PAX Water Mixer by its power cord up just below the surface of water (do not pull
out of the water) to verify operation (water movement).
3. In the event that the PAX Water Mixer is not working, contact your PAX representation for
technical support.
4. It is recommended that every five years, the PAX Water Mixer motor be replaced. Contact
your PAX representative for details on the motor exchange program.
