SYSTEM CHECK ON STARTUP
Note: Unit is equipped with 3 Phase Scroll compressors
and Evaporator blower motor. If refrigerant pressures are
abnormal and blower is rotating opposite direction of the
arrow, shut off main power to the unit and switch any two
fi eld wires at the disconnect or terminal block.
DO NOT ALTER UNIT WIRING.
Ensure proper rotation of both compressors and blower
motor. Listen for any unusual noises. Locate the source
and correct as needed.
The installation sequence is as follows:
1. Read these installation instructions completely before
proceeding.
2. Disconnect all power to the unit.
3. Remove the Element/Field Wiring Access panel.
4. Using the supplied screws, install the 3-pole terminal
block with the insulator plate between the sheet metal
panel and the terminal block. The terminal block should
be installed to the bottom left side of the element
mounting location, on the left side of the panel. See
fi gure 1. Tighten the screws hand tight, enough to
securely fasten the terminal block and insulator plate
to the panel and prevent any movement of the terminal
block. Over-tightening can crack the terminal block.
Note: For convenience both the factory installed
terminal board and the newly installed terminal
block are horizontally aligned when installed. In this
orientation, L1, L2 and L3 are installed in that order
from left-to-right.
5. Remove the unit control panel, access cover.
6. Carefully remove the zip-ties securing the main unit
wiring harness together on the upper right side and
top of the element mounting panel. (see picture 1)
7. Trace back & identify the Stage 1 and Stage 2 (if
equipped) compressor feed wires from the compressor
contactors to the factory installed terminal board.
8. Transfer the compressor feed wires from the factory
terminal board to the top box screw lugs of the newly
installed terminal block. Ensure that the factory phase
orientation is maintained during the transfer. Refer to
the unit wiring diagram to verify the proper orientation
if necessary.
For two-stage equipment, it is allowable to install
both compressor feed wires into the same box screw
lug, but the installer must ensure that both wires are
secured properly in the lug and that they can not
short to the panel.
a. On some models, with the optional indoor motor
overload protector installed, there are three
additional feed wires connected to the factory
installed terminal board for the indoor blower
motor. If so equipped, remove the blower
feed wires from the factory terminal board,
and terminate the wires with the proper gauge
(supplied) insulated female quick connector.
Then install the terminated wire onto the newly
installed terminal block spade connector for the
proper phase. Verify the new wiring matches the
unit wiring diagram for phase orientation.
9. Ensure all connections are secure.
10. Bundle all of the recently moved feed wires back
together into a neat harness and secure as needed
using the wire ties and panel mounted push ties to
route the harness up the left side of the panel to the
unit control panel. Then replace any other push-ties
along the top of the panel and down the right side of
the panel to re-secure the low voltage wiring harness.
Ensure all harnesses are routed away from any heater
elements and/or other objects which could come in
contact with the wiring harnesses.
11. Connect the unit input power wires from the unit
disconnect to the bottom box screw lugs of the newly
installed terminal block.
12. Replace the control panel cover and Element access
panel
13. Return power to the unit.
14. Verify unit operates properly.
See Circuit “A” - Electrical Data (Cooling) on unit
rating
label or in the Installation Instruction of the heater
kit for proper high voltage wiring requirements.
Mark the unit rating label with a permanent marker to
indicate the appropriate heater kit that is installed.
