Connecting to electrical supply

WARNING: Fan accessory must be grounded. Fan comes with a three-prong, grounding plug as shown in Figure 21. The plug is your protection against electrical shock. Plug it into a standard, three-hole, grounded, outlet. If cord needs replacing, use only a cord with a three- prong, grounding plug.

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and danger- ous operation (see page 29).

Extension Cord

Use extension cord if needed. The cord must have a three-prong, grounding plug and a three-hole receptacle. Make sure cord is in good shape. It must be heavy enough to carry the current needed. An undersized cord will cause a drop in line voltage. This will result in loss of power and overheating. Use a No. 16 AWG cord for lengths less than 50 feet (15.24 m) .

CAUTION: Verify proper op- eration after servicing.
