Long Control Box
1. If the long control box was provided, make electrical
connections to a field supplied junction box that should
be fastened to the floor beneath the control
(Figure 15).
2. Locate the long control box. The power wires for the
control extend through the piece of flexible conduit that
exits from the bottom of the control. These wires should
be connected to the incoming power at the junction box
installed in Step 1.
Remote Control — For units with remote mounted
thermostat, refer to page 14.
