the power connector approximately one inch out of the way while
sliding the wiring cover from the cabinet, as illustrated in

Step 2. Take care not to disconnect the wires from the back of the
power connector as you rotate it out of the way. After mounting the
cabinet with the appropriate screws, reinstall the power wire cover
in reverse order of disassembly, making sure that the wire
connectors remain firmly attached to the back of the electrical
connect as you do so.
8. Seal seams with tape or caulking after the air purifier cabinet has
been secured.
Special consideration must be given when applying the 2025 air purifier
to a 24½ inch (622 mm) wide furnace.
1. Prepare transition, following recommended transition drawing
). Fabricate a 2¼ inch (57 mm) tall (minimum) transition.
2. Place transition on top of air purifier. Secure with sheet metal
screws. Place furnace on top of transition. Make sure furnace rests
evenly on top of transition and air purifier.
3. Secure furnace to transition using sheet metal screws.
4. Continue with normal installation practices.

Wiring
For the wiring in the furnace and fan coil wiring
compartments
The incoming power supply wiring and connections for the air purifier
should be routed away from the output duct of the furnace or fan coil
unit, and the incoming power connections for the air purifier in the
furnace or fan coil unit must be properly rated. The maximum rated
current draw for the furnace 120VAC and fan coil 230VAC air purifiers
is 0.3 Amps.
The installation involves direct connection to the duct and to a furnace
controller EAC terminal output. The field wiring connection shall be
suitable for a maximum possible rating of 90°C of the field wiring
terminal box/terminals.
1. Ensure power has been removed from the heating and cooling
system.
2. Turn the air purifier power switch off.
For mounting on furnaces:
3. Route the power conduit from the purifier to a knockout on the
furnace that provides access to the EAC terminals on the furnace
control board. Affix the end of the conduit to the furnace using the
included conduit fitting.
4. Attach the quick connect terminals on the wires exiting the power
conduit assembly to the furnace EAC-1 and EAC-2 spade
connections. Attach the ground ring terminal on the third wire to
furnace chassis ground (
).
The air purifier should only be powered when airflow is present. The
furnace control EAC spade connections, shown in
, provide
power only when the furnace blower is operating. Air purifier models
DGAPAXX1625 and DGAPAXX2025 are designed to be powered from
the electronic air cleaner (EAC) terminals on a furnace electronic
control. If EAC terminals are not available, the Accessory Flow Sensor
Kit (
) must be purchased for use with the air purifier.
