SECTION I: GENERAL
The outdoor units are designed to be connected to a matching indoor coil with sweat connect lines. Sweat connect units are factory charged with refrigerant for the highest sales volume evaporator plus 15 feet of field supplied lines.
Matching indoor coils are available with a thermal expansion valve or an orifice liquid feed sized for the most common usage. The orifice size and/or refrigerant charge may need to be changed for some system combinations, elevation differences, or total line lengths. See tabular data sheet provided in unit literature packet for charge requirements. Refer to Application Data covering “General Piping Recommendations and Refrigerant Line Length” (Part Number 247077).
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.
