unit, performing any maintenance or
removing panels or doors. More than one
disconnect may be required to turn off all
power.
FAILURE TO DO SO COULD RESULT IN
BODILY INJURY OR DEATH.
Unit must be grounded in accordance with national and
local codes. Failure to ground unit properly can result in
personal injury or death.
Line voltage is present at all components when unit is
not in operation on units with single pole contactors.
Disconnect all remote electric power supplies before
opening access panel. Unit may have multiple power
supplies. Failure to disconnect all power supplies could
result in personal injury or death.
Refer to the furnace or blower coil Installation Instructions
