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 factor 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).
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.
LIMITATIONS
The unit should be installed in accordance with all National, State and
Local Safety Codes and the limitations listed below:
1.
Limitations for the indoor unit, coil, and appropriate accessories
must also be observed.
2. The outdoor unit must not be installed with any duct work in the air
stream. The outdoor fan is the propeller type and is not designed
to operate against any additional external static pressure.
3. The maximum and minimum conditions for operation must be
observed to ensure a system that will give maximum performance
with minimum service.
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.
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 maintenance
can cause injury or property damage. Refer to this manual for assis-
tance or for additional information, consult a qualified contractor,
installer or service agency.
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.
