Electrical connection

• Before commencing electrical connection, ensure that the mains supply is switched off and isolated.

• Connect electrical supply, see wiring diagrams.

• All installations and wiring must comply with current IEE regulations,
  Note: WAC1 B and WAC6/WAC3 C only:
  For conventional use of the fan, connection should be made between the ’LF’ terminal in the controiler and the ‘LF’ terminal in the fan.
  Alternatively if either the WAC6 or WAC3 controller is required to operate the fan in reverse, the connection should be made between the ‘LF’ terminal in the controller and ‘LR’ terminal in the fan. Installation instructions are included with the controller.

• Low voltage (LLOV-127V) versions of the WAC6 and WAC6R (WAC3 and WACSR) will control up to 3 Whispair 110V-127V Ceiling Sweep Fans.

• The NWAN ceiling sweep fan must be connected to the electrical supply through a suitable double pofe isolating switch (not supplied) and protected by a suitable fuse (54 max).

If you experience any difficulty in understanding these electrical requirements, you should consult Xpelair’s Technical Sales Department or a qualified electrician prior to making any electrical mains connections.
When the electrical connection is complete, slide the top canopy into position covering the top bracket assembly and preventing access to electrical connections. Secure by tightening the screw.
