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 smallest rated indoor coil 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 indoor-out-
door unit combinations, elevation differences 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.
