Step 2 - Mounting the Unit
E.
Ream both inside and outside of the refrigerant
tubing where a cut has been made. Use every
precaution to ensure reamed copper chips not to
lodge inside the tubing.
Install the factory-supplied flare nuts on the
refrigerant tubing using an R-410A flaring tool
ONLY. Apply a small amount of refrigerant oil to
the back of the flare and threads.
Tighten the flares with a torque wrench and back-
up wrench to the specifications found in the outdoor
unit Installation Manual.
F.
Connect the grey flexible drain hose supplied
to the condensate pump discharge pipe. Tighten
the clamp securely. Using 3/4 " PVC, connect the
flexible hose to the building's condensate drain
system.
G.
Route the 14AWG stranded 4-conductor power/
communication cable and the wired remote cable
to the air handler. Be sure to secure wire using
strain relief. Use reducing washers and appropriate
connector to attach the power/communication cable
to the unit. The wired remote cable will enter the unit
through a rubber grommet. The 4 conductor cable
connects to the terminal block at terminals (L1),
2(L2), 3(C) and Ground. The wired remote cable
connects to the air handler main board at connector
CN1 (ABC). Re-install electrical box cover.
