SECTION I: GENERAL
The outdoor units are designed to be connected to a matching indoor
coil with sweat connect lines. Sweat connect units have been shipped
from the factory with a nitrogen holding charge.
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). This unit has a com-
pressor containing POE oil.
This unit does not contain any refrigerant. It contains a nitrogen hold-
ing charge. Operating this unit with the nitrogen holding charge will
damage the compressor.
Before operating this unit, vent the nitrogen and evacuate the entire
system below 500 microns. Weigh in the refrigerant using the Tabular
Data Sheet and Installation Manual.
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.
