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 a matching indoor coil plus 15 feet of field supplied
lines.
Matching indoor coils are available with a thermal expansion valve
sized for the most common usage. The refrigerant charge may need to
be changed for some indoor-outdoor unit combinations, elevation differ-
ences or total line lengths. Refer to Application Data covering "General
Piping Recommendations and Refrigerant Line Length" (Part Number
036-61920-001).
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-
