WARNING:
Improper installation, or installation not made in
accordance with these instructions, can result
INUNSATISFACTORYOPERATIONANDORDANGEROUS
conditions and can cause the related warranty
not to apply.
The condensing unit is designed to operate with
standard 24 VAC thermostats and air handlers or
gas furnaces.
This installation instruction manual contains
complete instructions for installation and setup
using conventional 24 VAC controls. Please refer
to the manufacturer’s specification sheets for
complete performance data, thermostat, and
accessory listings.
The information contained in this manual has
been prepared to assist in the proper installation,
operation, and maintenance of the air conditioning
system.
Read this manual and any instructions packaged
with separate equipment required to make up the
system prior to installation. Homeowner should
retain this manual for future reference.
To achieve optimum efficiency and capacity,
the matching indoor cooling coils listed in the
manufacturer’s specification sheet should be used.
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.
Application
Before specifying any air conditioning equipment,
a survey of the structure and a heat gain
calculation must be made. A cooling heat gain
calculation determines the amount of heat needed
to be removed. A heat gain calculation also
calculates the extra heat load caused by sunlight
and by humidity removal. These factors must be
considered before selecting an air conditioning
system to provide year-round comfort. The Air
Conditioning Contractors of America (ACCA)
J Manual 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 unit provide the
comfort it was designed to provide.
There are several factors that installers must
consider.
sOutdoor unit location
sIndoor unit blower speed and airflow
sProper equipment evacuation
sSupply and return air duct design and sizing
sRefrigerant charge
sSystem air balancing
sDiffuser and return air grille location and sizing
