2. Now, carefully feed the end of the line set you
unrolled through the exterior wall hole and
route it to the ceiling hole/installation location.
Step 5: Connect DIYPRO™ Cable to Indoor
Unit
In this step, you will connect the DIYPRO™ Cable to
the indoor unit. This cable is how the indoor and
outdoor units communicate with one another. The
wiring within this cable is covered by a durable and
flexible conduit covering.
1. Remove the four screws shown in the image
below. Removing these will allow you to open
and access the indoor control box and circuit
breaker box (See Fig. 5.8).
2. You will notice three circular covers on the
circuit breaker box, as shown in the illustration
below. The two covers labeled No. 1 in Fig. 5.9
below are each suitable to use to feed the
DIYPRO™ cable into the circuit breaker box. The
hole labeled No. 2 is suitable for other types of
cables. Break-out and remove one of the
circular covers for the DIYPRO™ Cable that best
suits your installation. Then, feed the end of the
DIYPRO™ Cable that has a metal clad into the
circuit breaker box through the break-out hole.

3. Now, you will connect the wires of the DIYPRO™
Cable to the terminals of the circuit breaker box.
There are 4 wires, 3 of them will be labeled 1, 2,
and 3. The 4th wire is a ground. The numbered
wires will correspond to the numbered terminals
of the circuit breaker box. Securely connect each
wire to the corresponding terminal. Then, securely
fasten the ground wire to the screw on the metal
plate in front of the circuit breaker terminals.
Please refer to Fig. 5.10 below.
