Full Product Manual

Please read the Warranty certicate before attempting any service on your power unit. The
motor in your power unit DOES NOT require oiling. The bearings have been lubricated and
sealed at the factory. Tampering in any way with the motor blower will invalidate your war-
ranty. Your central vacuum system has been engineered to provide many years of carefree
service. Should your system for some reason fail to function properly, the following chart
and instructions should help you to restore ecient service promptly. Check the chart for
symptoms and then read across to determine the probable cause. The probable causes are
numbered for your convenience and after you have found your symptom, refer to the direc-
tions for checking that item.
1. Power Cord - Make sure that the power cord is plugged into an operating receptacle of the
proper voltage and current for your unit.
2. Push-to-Reset Circuit Breaker - If your unit has experienced an over current or extremely
high temperature, the button will pop out. To reset, simply push the button in until it pro-
trudes about 1/8 inch and stays in. If the breaker pops out again when the unit is used - call
your service technician.
