2.0 GENERAL INFORMATION
WARNING:
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.
2.1 Introduction
The (-)A17 series condensing units are specifically
designed to operate with matching communicating
EcoNet™ enabled air-handlers, gas furnaces, and
Control Center. A conventional 24VAC 2-stage
thermostat can be used, but many features and
benefits are lost, so this is only recommended for
emergency situations when there are issues with
the EcoNet™ communications and the system
must be made operational until the communication
issues are resolved.
This installation instruction manual contains
complete instructions for installation and setup
using the EcoNet™ or conventional 24VAC
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.
2.2 Agency
Performance Audit
Testing Notice
For purposes of verifying or testing efficiency
ratings, the test procedure in Title 10 APPENDIX
M to Subpart B of Part 430 (Uniform Test Method
for Measuring the Energy Consumption of
Central Air Conditioners and Heat Pumps) and
the clarifying provisions provided in the AHRI
Operations Manual 210/240 that were applicable
at the date of manufacture should be used for
test set up and performance.
Should this unit be selected for performance audit
testing, follow the instructions included in the
Appendix (Section 12.1) of this manual.

2.3 Importance of
Quality Installation
A quality installation is critical to assure safety,
reliability, comfort, and customer satisfaction.
Strict adherence to applicable codes, the
information in this installation manual, the outdoor
unit installation manual, and the thermostat
installation manual are key to a quality installation.
Read the entire instruction manuals before starting
the installation.
IMPORTANT:
designed and manufactured to meet certified AHRI
capacity and efficiency ratings with the appropriate
outdoor units. However, proper refrigerant charge,
proper airflow, and refrigerant line sizing are critical to
achieve optimum capacity and efficiency and to
assure reliable operation. Installation of this product
should follow the manufacturer's refrigerant charging
and airflow instructions located in this installation man-
ual and the charging chart label affixed to the outdoor
unit. Failure to confirm proper charge and airflow may
reduce energy efficiency and shorten equipment life.
The equipment has been evaluated in accordance
with the Code of Federal Regulations, Chapter XX,
Part 3280.
Install the unit in accordance with applicable
national, state, and local codes. Latest editions
are available from: "National Fire Protection
Association, Inc., Batterymarch Park, Quincy, MA
02269." These publications are:
• ANSI/NFPA No. 70-(Latest Edition) National
Electrical
Code.
• NFPA90A Installation of Air Conditioning and
Ventilating Systems.
• NFPA90B Installation of warm air heating and air
conditioning systems.
Install the unit in such a way as to allow necessary
access to the coil/filter rack and blower/control
compartment.
2.4 System Sizing and
Selection
Before specifying any air-conditioning equipment,
a survey of the structure, a heat gain calculation must
be made. A heat gain calculation involves identifying
all surfaces and openings that allow heat to enter the
building and 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.
