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. 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 horizontal position. Top and side power wiring and control wiring, accessible screw terminals for control wiring and easy to install electric heaters all combine to make the installation easy, and minimize installation 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 ...
