1.06 POWER AND CONTROL WIRING (ROUGH-IN)
A.
Line voltage power supply
must be sized to provide adequate power for the
operation of the specific model heat pump and, if chosen, the electric heat option.
Information on line power requirements, line sizing and fuse sizing is shown on data
label on unit. The power leads can enter the heat pump or air conditioner either
through the bottom or rear. The locations of the knockouts for power leads are
shown in Figure 3. Depending on the location of the Scholar III heat pump or air
conditioner relative to the outside wall, the exact rough-in location for power lines in
the school room can be determined. Six feet of power line should be available inside
the cabinet for routing and connecting the power lines, after the Scholar III unit is
installed. If entry is from bottom, the stub-out should be no higher than 1/2” from the
classroom floor to allow the unit to slide into the wall opening.
IMPORTANT
IF “S CIRCUIT” POSITION IS SELECTED ON THE ELECTRIC HEAT CONTROL (SEE
ARTICLE 1.11), LOWER MINIMUM CIRCUIT AMPACITY MAY BE PERMITTED.
B.
Low voltage wiring
can be roughed in to either the back (outside wall) or bottom
(floor) of the cabinet. Six feet of low voltage wire should be available for routing and
termination within the unit. If the entry is from the bottom, the stub-out should be no
higher than 1/2” from the classroom floor to allow the Scholar III heat pump and air
conditioner to slide into the wall opening. Reference Figure 3 as noted above, for
control wiring entry points into the cabinet.
