extension cord. Personal injury or damage to the
unit may result.
Be sure that your outlet matches the appropriate
blade configuration of the supplied plug and that it is
within reach of the service cord. A hardwire kit is
available as an accessory to change cord-connected
units to hardwired units. The junction box can be
mounted with manufacturer's non-electric subbase ac-
cessory. (See Accessories section, page 18.)

NOTE: Use copper conductors only.
• GROUNDING -- For safety and protection, the unit
is grounded through the service cord plug or through
separate ground wire provided on hardwired units. Be
