2.7.4 Air-Cooled Split Systems
The following system interconnecting field wiring
sections detail the number of conductors required for a
typical system. Additional control conductors may be
required depending on the options purchased with the
equipment. Refer to the electrical schematic supplied
with your unit to determine the total number of inter-
connecting conductors required for your system. It is
important to note that the control transformer(s)
supplied with the equipment have been sized and
selected based upon the expected loads for each
system.
CAUTION
Do not connect any additional loads to the
system control transformers. Connecting
additional loads to the factory supplied control
transformer(s) may result in overloading of the
transformer(s).
2.7.4.1 Remote Condenser (AR Models)
Systems equipped with a remote condenser will
require field wiring between the A/C system and the
remote condenser, see, (Figure 7). Refer to the
electrical schematic supplied with your unit and the
wiring diagram supplied with the condenser, (typically
located in the condenser electric box). The installer
must provide main power wiring to the main power
distribution block located within the remote condenser
control box. A separate equipment ground lug is
provided within the electrical box for termination of the
earth ground wire. The installer must also wire control
conductors from the terminal board within the A/C unit
to the control terminal board within the remote con-
denser control box. Refer to the electrical schematic
for the correct number of field wires needed and for
appropriate wire terminations required for your specific
system.
