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 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.

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-

tractor, installer or service agency.

This product must be installed in strict compliance with the

enclosed installation instructions and any applicable local, state,

and national codes including, but not limited to building, electrical,

and mechanical codes.
