INSTALLATION STEPS
14
Using 10 or 12-conductor, 18 AWG, color-coded, insulated (35C minimum) wire, connect the control system components between
the Acadia outdoor unit, the indoor air handler unit, and the thermostat, see (Fig. 6 through 9, Appendix B).
All wiring must be NEC Class 1 and must be separated from the incoming power leads. The Acadia outdoor unit has a 75VA, 24VAC
transformer for control power. To ensure correct operation of the system, the 40VA transformer located in the indoor air handler
unit must be disconnected from the control board, and the leads properly insulated to prevent possible shorts.
Following the color codes provided in (Fig 6 through 9, Appendix B), make connections to the Acadia outdoor unit, the indoor air
handler, and the thermostat. Connections may be made using either the 1/4female disconnects or using stripped wire with the
screw terminals provided.
(NOTE) Ensure the supplied thermostat and indoor air handler unit are installed and properly wired.
(NOTE) Ensure the air handler jumpers are placed in the appropriate position and that all wiring follows color code instructions.
CONFIGURING THE HEAT PUMP COMPONENTS
Minimum air flow for the Acadia048 is 1300 CFM or 36.8 m3/min. for a 2
nd
Stage call. Set the control jumpers in the air handler
accordingly. If using the Factory Supplied air handling unit, the recommended air flow is 1600 CFM or 45.3 m3/min. See (Fig. 4
and Table 10 through 12, Appendix A). Jumper settings are Heat: A, Delay: A, Cool: B, Adjust: A.
Minimum air flow for the Acadia036 is 1000 CFM or 28.3 m3/min. for a 2
nd
Stage call. Set the control jumpers in the air handler
accordingly. If using the Factory Supplied air handling unit, the recommended air flow is 1200 CFM or 34 m3/min. See (Fig. 4
and Table 10 through 12, Appendix A). Jumper settings are Heat: A, Delay: A, Cool: A, Adjust: A.
Minimum air flow for the Acadia024 is 700 CFM or 19.8 m3/min. for a 2
nd
Stage call. Set the control jumpers in the air handler
accordingly. If using the Factory Supplied air handling unit, the recommended air flow is 800 CFM or 22.6 m3/min. See (Fig. 4
and Table 10 through 12, Appendix A). Jumper settings are Heat: A, Delay: A, Cool: B, Adjust: B.
If an electric heat package is installed in the indoor air handler unit, be sure the control board is properly configured for the
electric heat package. If using the Factory Supplied air handling unit, move the Heat/No Heat jumper on the control board to
Heat; see (Fig. 4, Appendix A).
Using the table in (Table 13, Appendix A), program the thermostat for proper operation with the Acadia outdoor unit.
It is essential to have a jumper between RC and RH as indicated on the thermostat diagram (Fig. 8, Appendix B) for correct
operation.
IMPORTANT: Ensure the Controller program in the outdoor unit is properly set; P0 for electric back up, P1 for dual fuel back up.
(Step 8 of the Installation Steps).
If the system is using the factory recommended EWC zone control, consult (Fig. 12, Appendix F) for proper wiring using the EWC
zone control.
IMPORTANT: Check the factory wiring and wire connections to ensure the terminations are secured properly. Check the wire
routing to ensure the wires are not in contact with electrical box components, sheet metal, tubing, etc.
Step 7 – Charging of the System
(CAUTION) Ensure both the vapor and liquid line service valves are completely open, back-seated.
