outdoor Electrical Connection
1. Remove the control cover from the unit by
loosening the fastening screw (Figure 30).
2. Take off the caps on the conduit panel.
3. Connect both the power supply and low voltage
lines to the corresponding terminals on the ter-
minal block (see Figure 32 and Figure 33).
4. Be sure to ground the unit by following local
codes (see Figure 31).
5. Allow for enough length (add several inches)
for each wiring.
6. Secure the cable with the cord clamp.
7. Secure conduit tubes with lock nuts.
8. Refix the control cover to the original position
with the fastening screw.
Always use a circuit breaker or time delay fuse when connect-
ing electrical wiring to the unit.
• Comply with local codes while running wire from the
indoor unit to the outdoor unit.
• Be sure to connect wire firmly.
• Separately wire the high and low voltage lines.
• Use heat-proof electrical wiring capable of withstand-
ing temperatures up to 167°F.
• Use outdoor and waterproof connection cable
rated up to 300V for the connection between
