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.
The 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.
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 mainte-
nance can cause injury or property damage. Refer to this manual
for assistance or for additional information, consult a qualified con-
