This appliance is not intended for use by children without responsible adult supervision.
Proper care should be taken to ensure safety.
Heat pumps, air conditioners & heating equipment should be installed, started up, and
serviced only by qualified installers and service technicians. Air conditioning, heat pumps
and refrigeration systems are hazardous due to high voltage electrical components,
high refrigerant pressures, and moving parts.
NOTE: Your actual air conditioning & heating system and related devices may differ
from the images shown in this manual.
