CAUTION: UNIT DAMAGE HAZARD
Failure to follow this caution may result in unit component damage. Operation of unit on improper line voltage constitutes
abuse and may cause unit damage that could affect warranty.
B. ROUTING POWER LEADS INTO UNIT
Use only copper wire between disconnect and unit. The high-voltage leads should be in a conduit until they enter the unit; conduit termination
at the unit must be watertight. Run the high-voltage leads through the hole on the control box side of the unit (see Fig. 7 for location). When the
leads are inside the unit, run leads to the control box (Fig. 8). For single-phase units, connect leads to the black and yellow wires (see Fig. 9).
C. CONNECTING GROUND LEAD TO UNIT GROUND
Refer to Fig. 8 and 9. Connect the ground lead to the chassis using the unit ground in the control box.
D. ROUTING CONTROL POWER WIRES
Form a drip-loop with the thermostat leads before routing them into the unit. Route the thermostat leads through grommeted hole provided in unit
into unit control box (See Fig. 7). Connect thermostat leads and unit power leads as shown in Fig. 9, 10A & 10B.
Route thermostat wires through grommet providing a drip-loop at the panel. Connect low-voltage leads to the thermostat as shown in Fig. 10A
& 10B.
