For personal safety be sure to turn the electrical power “OFF” at the main entrance (Home
Circuit Breaker Box) and at the unit control box circuit breakers before attempting any service or
maintenance operations. Homeowners should never attempt to perform any maintenance which
requires opening the air handler control box door.
This air handler is not equipped with a shield that covers the line voltage electrical supply wires and
the circuit breaker connections. Take precautions to prevent accidental electrical shock. Be sure to
turn the electrical power “OFF” at the main entrance (Home Circuit Breaker Box) and at the control box
circuit breakers before removing the front panel.
