Trouble s hooting
Troubleshooting instructions are based on a logical sequence of events leading to a malfunction. If trouble
occurs, look for the simplest solution first such as whether the power supply is connected. Are any
connections loose or wires broken? Review the problem, normal operating procedures, and then check one
possibility at a time starting with the easiest to verify. If the malfunction continues, call the Manning
Environmental, Inc. Service Department at 1-800-863-9337. We can often assist over the phone. We can
also advise on whether or not certain repairs are best done in the field or in our factory.
Note: Follow instructions in the Maintenance section when removing the controller (see page 3-4)
