(To ensure proper performance of product, instructions must be followed.)

  1. Disconnect power to unit at main panel. Disconnect power to the low voltage thermostat circuit.
  2. Locate secondary condensate port on air handler.
  3. You have been supplied with 1 (one) pipe fitting connector. Apply pipe tape to male threads.
  4. Apply pipe tape to male threads
  5. Screw Fitting into Auxiliary Port. Use wrench to tighten. DO NOT OVER TIGHTEN.

WIRING THE BG-301 IN A CONVENTIONAL HVAC SYSTEM

(To ensure proper performance of product, instructions must be followed.)

  1. Ensure the power is disconnected to the unit at the main panel prior to moving to the next step. Refer to the appliance manufacturer’s installation and operating instructions and also review wire layout in their instructions.
  2. Locate the Red wire coming from the 24 volt thermostat “R” terminal.
  3. Disconnect or cut red wire. Connect wire of the switch, using a wire nut, to the thermostat side of the circuit. Connect the other wire of the switch, using a wire nut, to the air handler side of the circuit or to the terminal in the unit. Incorporating both switch wires in the red circuit will shut the unit off (fig.2)

4. TEST THE SWITCH

Check that float is in the lower position. If its not, lower the float using your finger (Fig 3)
At start up, check initial average load

With unit on, test switch by raising float as shown. Unit should stop running if switch is correctly wired.
To test switch responsiveness fill pan with water to ensure that the switch stops the unit before the pan over flows. Remove the water.
