the front panel for the 36K to 48K size to access wire terminals.
POWER AND WIRING INSTALLATION
Outdoor Unit Power Wiring
Insert main power wires through the wire holes on conduit mounting
bracket. Secure main electrical power conduit with locking nuts to
conduit mounting bracket. Locate wire terminals L1 and L2. Adjust
wire lengths for proper connections to the outdoor unit terminal block.
Connect main electrical power outdoor unit to terminals L1 and L2.
Connect Ground wire to ground terminal/screw. Secure electrical wires
inside wire clamp/strain relief. Verify wires are secure, not loose and no
external force on wires affects the connections at the terminals. Replace
and secure electrical box cover to outdoor unit.
NOTE:
Crossing communication wires will cause an E6 system
malfunction code and possible damage.
Outdoor Communication Wiring
Connect communication cable from indoor unit to terminals
#1 and #2. Maintain the same wire colors and terminal references
as indoor unit wire connections.
Secure cable inside wire clamp/strain relief. Verify cable is secure, not loose
and no external force on wires affects the connections at the terminals.
NOTE:
When connecting the power wire, make sure that the phase of the power supply matches
with the exact terminal board. If not, the compressor will rotate reversely and run improperly.
Tether Controller Wiring (Optional)
Use a minimum 18-2 AWG wire (field supplied) to connect Tether Controller to the indoor unit.
Route wire from Tether Controller into electrical box. Locate wire terminals H1 and H2. Connect
Tether Controller wires to H1 and H2. Verify wires are secure, not loose and no external force
on wires affects the connections at the terminals. Follow instructions provided with Tether
Controller to complete the installation.
Complete Indoor Installation
Replace the electrical box cover, both right and left side panels
and inlet air grille.
