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.

Requirements For Installing/Servicing R-410A Equipment

• Gauge sets, hoses, refrigerant containers, and recovery system

must be designed to handle the POE type oils, and the higher

pressures of R-410A.

• Manifold sets should be 800 PSIG high side and 250 PSIG low

side with 550 PSIG low side retard.

• All hoses must have a 700 PSIG service pressure rating.

• Leak detectors should be designed to detect HFC refrigerant.

• Recovery equipment (including refrigerant recovery containers)

must be specifically designed to handle R-410A.

• Do not use an R-22 TXV.

• A liquid-line filter drier is required on every unit.

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.

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.

R-410A systems operate at higher pressures than R-22 systems.

Do not use R-22 service equipment or components on R-410A

equipment. Service equipment

Must Be Rated for R-410A.
