GENERAL INFORMATION Downdraft Vent Hood Component layout This Illustration shows the general location of all operational components on the downdraft vent hood. The components are numbered as shown on the product wiring diagram (next page). The wiring diagram (shown on the next page) is available on the unit and also printed in the Installation Instructions with the product.
GENERAL INFORMATION Shown on the Product Wiring Diagram is the component parts layout chart and within the wiring diagram the electrical components are numbered per the component chart. You can also see the adjustable blower speed switch testing information and a motor specification chart. We can come back to this diagram later if necessary, but let’s look at something a little more helpful.
GENERAL INFORMATION Downdraft Vent Hood diagram – different format This is a complete picture of the wiring diagram on the previous page but in a different format. This circuit shows the vent sitting idle in the down position just like the product wiring diagram. We numbered the electrical components on the diagram per the component chart on the product wiring diagram.
GENERAL INFORMATION The other thing that is important is what happens when the Pushbutton is pressed. A complete 120 VAC circuit is created through the two filter switches, the pushbutton (as it is being held down by the operator), and the motor to the neutral side of the line. As you notice with this circuit, until the Plenum DOWN Limit switch is closed the only power to the motor is through the pushbutton switch.
GENERAL INFORMATION As soon as the plenum rises to it fully open position, the Plenum UP Limit switch will change position and open the circuit to the motor. The only time we need the exhaust blower motor to run is when the plenum is fully open.
