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 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

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.

INSPECTION

As soon as a unit is received, it should be inspected for possible dam-

age during transit. If damage is evident, the extent of the damage

should be noted on the carrier’s delivery receipt. A separate request for

inspection by the carrier’s agent should be made in writing. See Local

Distributor for more information.

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.
