CAUTION
Electrical Wiring Installation
Remove terminal covers from indoor unit
and wire to the terminals, (small screw
-
driver required). Control wiring from the
outdoor unit must be a point to point i.e.
the terminal that the wire is attached to on
the outdoor unit must be the same termi
-
nal it is wired to in on the indoor unit.
THIS IS EXTREMELY IMPORTANT:
Switching the L3 - L4 or N1 - L1 wires
will allow the indoor unit to operate
but it will not provide controls signals
for the outdoor unit so that the com-
pressor will not operate. Ground con-
nection should be made to ground
screw marked in indoor unit.
Ground wires connected to the terminal
plate indoor and outdoor units must be
grounded.
