WIRING

STEP 6 — PRECAUTIONS: READ CAREFULLY BEFORE WIRING FAN!

A.Electrical connections and all wiring should be in accordance with the National Electrical Code and all local codes that may apply.

B.To avoid possibility of serious injury or electrical shock, the installer must disconnect electrical circuit supplying power prior to wiring fan.

C.CAUTION: Incorrect wiring can cause motor failure and possibly fire. Marley Engineered Products will not accept liability for damage resulting from incorrect wiring. Follow all wiring diagrams and instructions carefully!

D.This fan is designed to run on 120 volt A.C. 60 Hz power only.

STEP 7 — The 3-speed control packed with this fan is used to operate the fan from a remote wall location. Generally the best location is in the hallway near the fan. The control should be in sight of the fan. Install a single switch box at the location chosen.

STEP 8 — The wiring diagrams, Figs. 6 & 7, show two alternate methods of wiring fan control. If the 120V power supply is available at the fan, Fig. 6 should be followed. If the 120V power supply is available at the control, Fig. 7 should be followed. In either case, note that the brown control wire must be connected to the black (hot) wire from the 120 volt power supply

STEP 9 — After determining which diagram applies, pull wires to fan and control switch box. Be sure to secure cable at fan to prevent it from being caught in fan blade. Make connections to fan from room below, through hole cut in ceiling. After wiring of fan and control is completed and checked against the appropriate wiring diagram, replace outlet box cover on fan and secure control in switch box. Leave control in “OFF” position.
