Wiring Instructions for Inter-Unit Connections
(a) Insert the inter-unit wiring (according to local
codes) into the through-the-wall PVC pipe. Run
the wiring toward the indoor side allowing approx.
5". to extend from the wall face. (Fig. 3-44)
Never fix the wiring by any
means before the indoor
unit is fully seated on the
rear panel.
(b) Remove the side cover and the metallic cover.
(Fig. 3-45 or 3-46, depending on model.)
(c) Secure the conduit connector to the chassis with
a lock nut. (Fig. 3-45 or 3-46)
(d) Give some play to the inter-unit wiring from the
outdoor unit to the corresponding terminals on the
terminal plate.
● Be sure to refer to the
wiring system diagram
label inside the metallic
cover and carry out the
correct field wiring.
Wrong wiring can cause
the unit to malfunction.
● Check local electrical
codes and any specified
wiring instructions or
limitations.
(e) Secure the metallic cover with its screw. Then
replace the side cover.
