through the hole provided in the unit corner post.
2. Feed wires through the raceway built into the corner post (see
Fig. 43) to the 24-v barrier located on the left side of the con-
trol box. The raceway provides the UL-required clearance
between high-voltage and low-voltage wiring.
3. Use wire nuts to connect humidistat cable to two PINK leads
in the low-voltage wiring as shown in Fig. 46.
