SECTION I: GENERAL

The AV single piece air handler provides the flexibility for installation in any upflow, downflow, or horizontal application.

These versatile models may be used for cooling or heat pump operation with or without electric heat.

A BRAND LABEL (available from Distribution) may be applied to the center of the blower access panel on AVG models.

The unit can be positioned for bottom return air in the upflow position, top return air in the downflow position, and right or left return in the hor- izontal position.

Top and side power wiring and control wiring, accessible screw termi- nals for control wiring, easy to install drain connections and electric heaters all combine to make the installation easy, and minimize installa- tion cost.

SECTION II: SAFETY

This is a safety alert symbol. When you see this symbol on labels or in manuals, be alert to the potential for personal

injury.

Understand and pay particular attention to the signal words DANGER, WARNING, or CAUTION.

DANGER indicates an imminently hazardous situation, which, if not avoided, will result in death or serious injury.

WARNING indicates a potentially hazardous situation, which, if not avoided, could result in death or serious injury.

CAUTION indicates a potentially hazardous situation, which, if not

avoided may result in minor or moderate injury. It is also used to

alert against unsafe practices and hazards involving only property dam- age.

Improper installation may create a condition where the operation of the product could cause personal injury or property damage. Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage. Refer to this manual for assis- tance or for additional information, consult a qualified contractor, installer or service agency.

This product must be installed in strict compliance with the installation instructions and any applicable local, state, and national codes including, but not limited to building, electrical, and mechanical codes.

FIRE OR ELECTRICAL HAZARD

Failure to follow the safety warnings exactly could result in serious injury, death or property damage.

A fire or electrical hazard may result causing property damage, per- sonal injury or loss of life.
