PREFACE
The following manual outlines the procedures and policies of the Performance Certification Program for
AHRI Unitary Small Air-Conditioners (including mixed-match coils) (USAC) and the AHRI Unitary Small Air-
Source Heat Pumps (including mixed-match coils) (USHP) operated by the Air-Conditioning, Heating, and
Refrigeration Institute (AHRI). This manual is to be used in conjunction with the AHRI General Operations
Manual for AHRI Certification Programs. Where the AHRI General Operations Manual and this product-
specific manual differ, this product-specific operations manual shall prevail.
The revision of this manual supersedes all previous revisions. The current edition of this manual, as well
as the AHRI General Operations Manual, can be accessed through the AHRI website,

.
The USAC and USHP Certification Program by AHRI provides for independent verification of the USAC
and USHP manufacturers
’ stated equipment performance. Safety criteria are not within the scope of this
program.
Participation in the program is voluntary. Any manufacturer, regardless of AHRI membership, may obtain
approval of Program Ratings and use of the AHRI USAC and USHP Certification Marks hereinafter referred
to as the “Marks”. The Marks are the Participant’s public representation that the ratings of randomly
selected units have been verified by an independent laboratory in accordance with test procedures
prescribed by this operations manual. A Certification Agreement is executed between the manufacturer
and AHRI specifying the conditions under which such Ratings and the Mark may be used. No manufacturer
has the right to use Program Ratings or to state that their products have been tested in conformance with
the procedures outlined in this Rating Procedure unless and until they have received written authority from
AHRI to use the Marks as applied to the specific approved Program Ratings.
This Operations Manual has been prepared to assure that administration of the program is carried out in a
uniform manner. It is an amplification of the license agreement signed by licensees and AHRI. General
information, procedural details, and copies of forms are included in this Operations Manual. Provisions of
the Operations Manual may be amended as provided in the Certification Agreements.
This certification program complies with requirements of the ISO/IEC Standard 17065:2012,
General
Requirements for Bodies Operating Product Certification Systems.
Note:
This manual supersedes the AHRI Unitary Small Air-Conditioners (including mixed-match coils) and AHRI
Unitary Small Air-Source Heat Pumps (including mixed-match coils) Certification Program Operations
Manual, USE OM March 2015.
