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 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.

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.

LIMITATIONS

The unit should be installed in accordance with all National, State and

Local Safety Codes and the limitations listed below:

1. Limitations for the indoor unit, coil, and appropriate accessories

must also be observed.

2. The outdoor unit must not be installed with any duct work in the air

stream. The outdoor fan is the propeller type and is not designed

to operate against any additional external static pressure.

3. The maximum and minimum conditions for operation must be

observed to ensure a system that will give maximum performance

with minimum service.

4. The unit should not be operated at outdoor temperatures below

50° F without an approved low ambient operation accessory kit

installed.

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.
