Electric Power Wiring
Before making any electrical connections, observe the
following precautions:
1. Check the nameplate rating of the heat section and
cooling chassis to make sure the equipment is connected
to the proper power supply and that proper fusing is used.
2. In cases where a number of conditioners are to be
installed, single circuits should be provided for each
machine.
3. A separate disconnect is recommended for each
conditioner in addition to individual fusing. This can be
accomplished in several ways:
a. By installing a remote double-pole switch in the
conditioner’s power line within sight of the unit.
b. By installing a double pole, single throw “on-off”
switch located in a convenient position within the
room cabinet.
After all these precautions are observed, proceed as follows:
Units With Electric Heat (Sizes 007–012)
A 4" x 4" electrical junction box is located on the left side of
the heat section. Field wiring should be brought to this point
for power to the unit. See Figure 12 & 13.
