outdoor electrical Connection
1. Remove the control cover from the unit by loosening the fastening screw (Figure 28).
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 terminal block (see Figure 30).
4. Be sure to ground the unit by following local codes.
5. Allow for enough length (add several inches) for each wiring.
6. Secure the cable with a cord clamp.
7. Secure conduit tubes with lock nuts.
8. Reattach the control cover to the original position with the fastening screw.
• Separately wire the high and low voltage lines. There is a risk of
electric shock, physical injury, or death.
• Use heat-proof electrical wire capable of withstanding tempera-
tures up to 167°F to avoid wiring malfunction and electrical shock,
which may cause physical injury or death.
• Ensure you connect the wire firmly. Loose wiring may cause unit
malfunction, the wires to burnout or the terminal to overheat and
catch fire. There is a risk of electric shock, physical injury or death.
• Use outdoor and waterproof connection cable rated up to 300V
for the connection between the indoor and outdoor unit to avoid
electrical shock, which may cause physical injury or death.
• Separately wire the high and low voltage lines to avoid damage to
unit.
• Use heat-proof electrical wire capable of withstanding temperatures
up to 167°F to avoid damage to unit.
• Always use a circuit breaker or time delay fuse when connecting
electrical wiring to the unit.
• Ensure you connect the wire firmly. Loose wiring may cause unit
malfunction, the wires to burnout or the terminal to overheat and
catch fire. There is a risk of equipment malfunction or property
damage.
• Use outdoor and waterproof connection cable rated up to 300V for
the connection between the indoor and outdoor unit to avoid dam-
age to the unit.
• Comply with local codes while running wire from the indoor unit to
the outdoor unit.
• Do not allow wire to touch refrigerant tubing, the compressor or any
moving parts since it can lead to mechanical failure.
