INFINITY CONTROLLED LOW AMBIENT COOLING NOTE: When this unit is operating below 55°F (13°C) outdoor temperature, provisions must be made for low ambient operation. This unit is capable of low ambient cooling down to 0°F (-18°C).ONLY when using the Infinity control.
CARBON MONOXIDE POISONING HAZARD Failure to follow this warning could result in personal iniury and/or death. If the manifold pressure and/or gas rate is not properly adjusted on HI and LO stages, excess carbon monoxide can be produced.

MAINTENANCE To ensure continuing high performance, and to minimize the possibility of premature equipment failure, periodic maintenance must be performed on this equipment. This packaged unit should be inspected at least once each year by a qualified service person.
ELECTRICALSHOCK HAZARD Failure to follow this warning could result in personal injury or death. Disconnect and tag electrical power to the unit before cleaning and lubricating the blower motor and wheel. Outdoor Coil, Indoor Coil, and Condensate Drain Pan Inspect the condenser coil, evaporator coil, and condensate drain pan at least once each year.
