Step 3 - Installation of the Outdoor Unit (Cont.)
B. Electrical Connections for the
Outdoor Unit
WARNING
RISK OF ELECTRIC SHOCK.
Could cause injury or death.
Make sure power is off before touching wires.
NOTE: Be certain all wiring complies with local
building codes and NEC and that the supply voltage for
this system matches the unit nameplate.
• Verify you are using a consistent length of wire
without breaks, excessive bends, splices or damage.
• Connect the wiring for both the power source and
the indoor wiring using a conduit cable bracket on
the side of the outdoor unit
• Using a wire stripper, remove the insulation and
separate the wires.
• Verify that the outdoor wiring connections match the
indoor connections wire-for-wire.
• Ensure each wire is under the screw terminal plate
and the plate is tightened.
• Ensure the 14/4 stranded wire cable is secured
under the strain relief bracket.
• Verify that all connections are secured and there is
continuity between terminals and ground.

C. Install Copper Lineset
• The standard line set length is 25 feet. If the
installation length is different, adjust the refrigerant
charge by adding 0.2 oz/ft if the liquid line is 1/4", or
0.5 oz/ft if the liquid line is 3/8".
• Cut the line set to length. Verify cuts are square and
ream out the ends.
• Place nut over the pipe and then flare with the
R-410A flaring tool as per the tool manufacturer's
instructions.
NOTE: When cutting and reaming the tubing, use
caution to prevent dirt or debris from entering the
tubing. Remember to place nut over the tubing before
flaring.
• To join the line set, directly align the
tubing flare to the half union fitting on
the other pipe. Slide the nut onto the
fitting and hand tighten.
• Two wrenches are required to join the flare
connection; one standard wrench and one torque
wrench adjusted to the proper settings.
• Using a calibrated torque wrench, torque the fittings
according to the specifications below.
NOTE: Forced fastening without careful centering may
damage the threads and cause a refrigerant leak.
