INSTALLATION STEPS
13
(NOTE)
Use a minimum 10 conductor, 18 AWG wire harness for control connections between the thermostat, indoor air handler
unit, and the Acadia outdoor unit. A minimum 10 conductor, 18 AWG wire harness must be used to prevent incorrect wiring of
the system.
IMPORTANT
:
Match the wiring color codes according to the system drawings for easy trouble shooting and standardization. For a
color code reference, see
(Fig.
6 through 9, Appendix B)
.
ROUTE GROUNDED AND POWER WIRES
(DANGER)
The Acadia outdoor unit cabinet must have an uninterrupted or unbroken ground connection to minimize personal
injury if an electrical fault should occur. The grounded connection may consist of electrical wire or metal conduit when installed
in accordance with existing electrical codes. Failure to follow this warning can result in an electric shock, fire, and/or death.
(CAUTION)
Line and Control voltage wires must be routed clear of any system components to prevent wiring chafing and/or
electrical shorts. Ensure Line and Control voltage wires are routed away from terminal connections of relays and capacitors.
Remove the access panel and electrical box cover to gain access to the unit wiring. Extend wires from the circuit disconnect through
the power wiring hole provided, into the unit control box. Size wires per the NEC.
CONNECT GROUNDED AND POWER WIRES
(CAUTION)
Test the grounded connection using a multi-meter set for ohms from the ground lug of the Acadia outdoor unit to
the service disconnect ground. Also, check for voltage from line to line and line to ground.
Connect the grounded wire to the ground connecting lug in the control box for safety. Connect the power wiring to the top L1 and
L2 lugs of the Booster Compressor contactor. For clarification, consult the wiring diagram
(Fig.5, Appendix B)
and
(
Fig. 11, Appendix
D)
. The 75VA transformer located in the Acadia outdoor unit is factory pre-wired for a 240VAC input. If the unit is being connected
to supply voltages other than 240VAC, consult the wiring diagram
(
Fig. 9, Appendix B)
.
ROUTE CONTROL WIRING
To route control wires to the interior of the Acadia outdoor unit, it is necessary to pierce the ½” rubber grommet and slide the
control wires into the electrical cabinet. While routing control wires through the unit, avoid routing across or around the Controller,
as this may generate unwanted interference, e.g. static, etc.
CONNECT CONTROL WIRING
(NOTE)
If using existing control wiring, be sure the harness is a minimum 10 conductor, 18 AWG and all the wiring is in good
condition.
(NOTE)
If the distance between the thermostat and the Acadia outdoor unit is more than 100-ft. or 30.5-m., as measured by the
control wiring, 16 AWG wire should be utilized to avoid an unnecessary voltage drop.
(NOTE)
The Acadia outdoor unit is supplied with a 75VA transformer with a built-in 3.7 amp breaker. Disconnect any other low
voltage power supplies.
(NOTE)
24VAC and COM needs to be supplied to the air handler control board; the 24VAC and COM terminals at the top of the
air handler control board.
IMPORTANT:
Ensure that no other control voltage transformer is connected to the system. Use only the 75VA transformer
supplied in the Acadia outdoor unit. Disconnect the secondary leads, control voltage wires, from the indoor air handler control
transformer to the air handler control board.
IMPORTANT:
Make sure to change the line voltage leads to the 75VA transformer if the line voltage is other than 240VAC.
