Note - In many instances the controller is blamed for faults caused by bad motors, tanks
with incorrect or no air charge, poor wiring and/or improper grounding. Since the SOLO
may be used to retrofit an existing installation into a variable speed system, IM229 includes
instructions on checking Motor Insulation Resistance and Winding Resistance. Before
replacing a SOLO drive on a retrofit installation please perform these tests to verify the
motor and wire are in good condition and the tank pressure is set properly.
