If a roof vent opening will not be used a 14-1/4" x 141/ 4" (±1/8") opening must be cut through the roof and ceiling of the RV. This opening must be located between the roof reinforcing members. There may be electrical wiring between the roof and the ceiling. Disconnect 120 volt AC power cord and the positive (+) 12 volt DC terminal at the supply battery. Failure to follow this instruction may create a shock hazard causing death or severe personal injury.
