Vertical Units
Notes:
• In vertical units, wiring to the motor transitions from
the control panel onto a trough onto the fan board.
• The motor harnesses are routed through holes at the
motor location below the fan board and into the
motors with a latching multi-plug.
• The crossover harnesses, which are used to make
connections to the piping side of the unit, are routed in
the same manner but continue to the piping side
entirely through the trough on the fan board.
• On vertical fan-coil units with drain pans, a drain pan
support covers most of the wiring. Please be sure to
remove or secure the wiring before removing fan
board.
• Fan board attachment screws are located on the front
left and right edges of fan boards, and may be
concealed by gasketing.
