FUSE BLOCK
2-pole DIN-rail mount finger safe fuse block rated for
600VAC.
OUTDOOR FAN MOTOR
Due to design considerations of the condenser section
of the wall-mount unit, placement/clearance of the
motor/fan blade is critical to heat dispersal. Should a
change of motor or fan blade be necessary, please view
Figure 2.18 for proper clearance adjustment.
INDOOR BLOWER MOTOR
Unlike most other system fan motors, this motor is very
specialized in application.See Table 2.5 (blower table).
