Refer to the Trouble Shooting guide in the
Classic Series Installation Manual
for motor conditions and solutions.
CAUSES OF MOTOR MALFUNCTION
LIQUID INTRUSION
The motor is fan cooled and needs proper ventilation while protecting it from
water intrusion.
Corrective Action
Mount the single head pump vertically with pump head downward and use the rain
roof in outdoor installations, in areas subject to wash downs, or in moist environments.
CHEMICAL VAPORS
The motor won’t be able to rotate freely if the coil, rotor and bearing are rusted or corroded.
Corrective Action
1.
Avoid mounting the pump over an open solution tank.
2.
Review vertical installation.
INCORRECT VOLTAGE
The motor voltage must match power supply to avoid a burned coil.
Corrective Action
Use a volt meter for confirmation.
DAMAGED BEARING BRACKETS
Cracked or broken bearing bracket(s) result in rotor mis-alignment that can cause the rotor
to bind to the magnetic coil that may be evident by a humming sound.
Corrective Action
1.
Check the condition of the brackets and phenolic gear.
2.
Replace parts as needed.
