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 nominal sized matching indoor coil plus 15 ft of
field-supplied lines.
Matching indoor coils can be used with a thermostatic expansion valve
(TXV). 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.
