General Information
Unit Specifications
These factors must be considered before selecting an
air conditioning system. The Air Conditioning
Contractors of America (ACCA) Manual J method of
load calculation is one recognized procedure for
determining the cooling load.
After the proper equipment combination has
been selected, satisfying both sensible and
latent requirements, the system must be properly
installed. Only then can the system provide the
comfort it was designed to provide.
There are several factors that installers must
consider.
• Outdoor unit location
• Indoor unit blower speed and airflow
• Proper equipment evacuation
• Supply and return air duct design and sizing
• Refrigerant charge
• System air balancing
• Diffuser and return air grille location and sizing
2.0 GENERAL INFORMATION
IMPORTANT:
Excessive use of
elbows in the refrigerant line set can produce
excessive pressure drop. Follow industry
best practices for installation. Installation
and commissioning of this equipment is to
be performed by trained and qualified HVAC
professionals. For technical assistance, contact
your Distributor Service Coordinator.
2.5 Importance of
Proper Indoor/Outdoor
To assure many years of reliable operation and
optimum customer comfort and to assure the
outdoor unit warranty remains valid, an air-handler
model or indoor coil/furnace combination should
be selected that is properly matched to the outdoor
unit. The recommended approach is to select an air-
handler or indoor coil and gas furnace that has an
AHRI match with the outdoor unit. Refer to the
AHRI directory at www.ahridirectory.org to confirm
the air-handler and outdoor unit are a certified
combination in the AHRI Directory.
2.6 Checking Product
Received
Upon receiving unit, inspect it for any shipping
damage. Claims for damage, either apparent or
concealed, should be filed immediately with the
shipping company. Check model number, electrical
characteristics, and accessories to determine if they
are correct. Check system components (indoor coil,
outdoor unit, air handler/furnace, etc.) to make sure
they are properly matched.
