Basic Troubleshooting

If the MSD pump does not operate properly, refer to the following troubleshooting charts as a

guide to determining the concern and identifying the potential cause. If after consulting the

troubleshooting charts the cause is still undefined, contact FEDCO technical support by e-mail

(fedco-usa.com and choose the “

Service and Support

” tab), telephone or FAX. FEDCO will give

you easy, step by step instructions on how to proceed.

Visual Inspection

• Make sure all items are accounted for on the start up check list.

• Inspect all piping and electrical connections to the motor and pump.

•

Inspect the pump and motor mountings for signs of any movement or vibration.

• Inspect pressure gauges, switches and all other instrumentation for proper operation.

• Record any unusual readings.
