Area-type and SDU dispersion fans

Connect wiring for Area-type and Space Distribution Unit (SDU)

dispersion fans by inserting the wire into the terminal block plug

at P16 (labeled SDU). Tighten screws; maximum torque is 3 in-lb

(0.34 N-m).

Optional combustion air switch and power vent (GTS systems)

Connect wiring for GTS combustion air switch and/or GTS power

vent by inserting wires into the terminal block plugs at P15 and

P16. Tighten screws; maximum torque is 3 in-lb (0.34 N-m).

The combustion air switch is on the combustion air damper. The

power vent switch indicates airflow at the power venter.
