SECTION I: GENERAL
These outdoor condensing units are designed to be connected to a
matching indoor coil. They are equipped with a filter-drier located in the
liquid line.
Units with quick-connect coupling connections are factory charged with
refrigerant to be matched with the appropriate pre-charged line set and
indoor coil.
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.
