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 can be used with a thermostatic expansion valve
(TXV) or an orifice. Refer to the Tabular Data Sheet or to the Technical
Guide for the proper selection.

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.
CAUTION

• 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 restart.
• 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.
