4.2 HVAC Fan Electrical Installation with 24VAC Transformer
a) Use multimeter to determine if 24VAC control signal wires are available. If yes go to
step b. If no, go to step c.
b) For 24VAC HVAC systems, refer to
Figure 7
. Loosen screws, insert wires (as
shown), and tighten screws with all wires in place. Connect greenfan® bipolar
ionizer blue wire to C terminal or to common wire of HVAC system. Connect black
wire to fan G terminal or fan G wire of HVAC system. Connect white wire to heat W
terminal or heat W wire of HVAC system. Skip to step d.
c) For HVAC systems without accessible 24VAC control signal wires, install
120/208/240V to 24VAC Class 2 UL-listed transformer (Model 1601-01) shown in
Figure 8
and
Figure 9
. Connect 120/208/240V common wire of transformer to
120/208/240V common wire of HVAC system and connect greenfan® bipolar ionizer
blue wire to one of 24VAC wires from transformer shown in
Figure 9
. Connect
greenfan® bipolar ionizer black wire to other 24VAC wire from transformer and
connect appropriate wire from 120/208/240V transformer to 120/208/240V hot wire
of fan. Transformer wire color may vary. Install wire nut to insulate white wire of
greenfan® bipolar ionizer shown in
Figure 9
.
d) After completing all steps of mechanical and electrical installation for HVAC system
proceed to HVAC fan verification of proper operation.
