2.0 GENERAL
The information contained in this manual has been prepared to assist in the proper
installation, operation and maintenance of the air conditioning system. Improper
installation, or installation not made in accordance with these instructions, can result
in unsatisfactory operation and/or dangerous conditions, and can cause the related
warranty not to apply.
Read this manual and any instructions packaged with separate equipment required
to make up the system prior to installation. Retain this manual for future reference.
To achieve optimum efficiency and capacity, the indoor cooling coils listed in the
condensing unit specification sheet should be used.
IMPORTANT:
We recommend replacement of any HVAC equipment that has been
subjected to flooding in order to avoid any risk of injury or harm.
IMPORTANT:
Use all available safety precautions during the installation and servic-
ing of any HVAC equipment.
2.1 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 condensing unit model number, electrical characteristics and accessories to
determine if they are correct and match the original order from the local distributor.
Check system components (evaporator coil, condensing unit, evaporator blower,
etc.) to make sure they are properly matched.
2.2 APPLICATION
Before installing any air conditioning equipment, a duct analysis of the structure and
a heat gain calculation must be made. A heat gain calculation begins by measuring
all external surfaces and openings that gain heat from the surrounding air and
quantifying that heat gain. A heat gain calculation also calculates the extra heat
load caused by sunlight and by humidity removal.
There are several factors that the installers must consider:
•
Outdoor unit location
•
Proper equipment evacuation
•
System refrigerant charge
•
Indoor unit airflow
•
Indoor unit blower speed
•
Supply and return air duct design and sizing
•
System air balancing
•
Diffuser and return air grille location and sizing
