Use a circuit breaker
Or time delay fuse
• Always use a circuit breaker or time delay fuse
when connecting electrical wiring to the unit
(Figure 28) to prevent mechanical failure.
• Comply with local codes while running wire
from the indoor unit to the outdoor unit.
• Be sure to connect wire firmly.
• Do not allow wire to touch refrigerant tubing,
the compressor or any moving parts since
it can lead to mechanical failure.
outdoor unit Electrical Connection
1. Remove the conduit cover from the unit by
loosening the fastening screws (Figure 27).
2. Take off the caps on the conduit panel.
3. Connect both the power supply and low volt-
age lines to the corresponding terminals on the
terminal block.
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 the cord clamp.
7. Secure conduit tubes with lock nuts.
8. Refix the control cover to the original position
with the fastening screw.
• Separately wire the high and low
voltage lines to avoid a fire hazard.
• Use heat-proof electrical wiring capable
of withstanding temperatures up to
167
°
F to avoid fire hazard.
• Use outdoor and waterproof connection
cable rated up to 300V for the connection
between indoor and outdoor unit a
avoid electric shock or fire.
• Do not allow wire to touch refrigerant
tubing, the compressor or any moving
parts. Doing so can lead to bodily injury.
