Unit Specications
The Air Conditioning Contractors of America
(ACCA) Manual J method of load calculation is one
recognized procedure for determining the heating
and 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
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 Match-Ups
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.
This is especially critical for heat pump systems to
assure proper refrigerant charge balance between
the cooling and heating modes. 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.
