1. Disconnect all power and lock out the unit.
2. Remove the air handler's side panel which conceals
the unit control box (the panel with the nameplate).
3. Remove and retain the 2 screws that secure the
hinged cover of the control box. See Figure 2, p. 6 .
4. Install the transformer using 2 screws and lock
washers (provided in Kit) on the divider panel in the
high voltage section. See
Figure 2, p. 6 .
5. Of the two power wire harnesses included with the
kit, choose the one that has terminations
appropriate to the type of connections and install
the harness per unit diagram:
• Harness with 1/4" Quick Connect terminals will
connect to the indoor fan contactor of units with
constant volume fan control.
• Harness with stripped leads will connect to the
fuse block of unit with SZVAV / 2-speed fan
control.
Discard the unused power wire harness.
6. Connect the 24 VAC harness from the transformer
to the relay board per unit diagram. See Figure 2, p.
6 .
7. Attach ground wire in 24VAC harness to the divider
panel using the green ground screw going through
wire terminal and lock washer. See
Figure 2, p. 6 .
8. Connect the harnesses to the transformer by
snapping together the in-line color coded
connectors.
9. Secure wires away from sharp edges using wire
ties (provided in kit).
10. Apply the safety agency label to the side of the
control box. See Figure 2, p. 6 .
N No otte ess::
• The 208/230V transformers are factory wired
for 230V. To convert to 208 volt power,
disconnect wire from the 230V terminal on
the primary side of the transformer and
reconnect to the 208V terminal.
• Full wiring schematics are available through
e-Library. If access is not available, contact
your local sales office.
11. Close and secure the high voltage access panel
using the 2 screws that were previously removed.
12. Re-install the air handler's side panel.
