(a) When Required. A Certificate of Operation shall be required for all refrigerating systems which contain a Group three (3) refrigerant, or contain more than five (5) pounds of a Group two (2) refrigerant, or more than twenty (20) pounds of a Group one (1) refrigerant. In determining the quantity of refrigerant contained within a refrigerating system the Commissioner may accept the certified statement of the manufacturer or the certified statement of a registered installer of refrigerating systems. Unless an existing refrigerating system is certified by the manufacturer or by a registered installer of refrigerating systems as containing twenty (20) pounds or less of a Group one (1) refrigerant or five (5) pounds or less of a Group two (2) refrigerant, each such system containing a Group three (3) refrigerant, and each such system containing a Group one (1) refrigerant and having a motor of one (1) HP or more, shall be required to have a Certificate of Operation.
(b) New and Altered Systems. A refrigerating system which has been installed or altered under a required permit shall not be operated more than five (5) days unless a Certificate of Operation has been issued by the Commissioner.
(c) Existing Refrigerating Systems.
(1) Existing refrigerating systems operated under authority of a certificate of inspection issued prior to June 27, 1949, may continue to operate under such certificate of inspection until the expiration date of such certificate. Subsequent to the expiration date of such certificate of inspection, such refrigerating system shall be operated only if a required Certificate of Operation has been issued by the Commissioner.
(2) An existing refrigerating system for which a certificate of inspection was not previously issued and for which a Certificate of Operation is required under the provisions of subsection (a) hereof, shall not be operated for more than six (6) months after June 27, 1949, unless a Certificate of Operation has been issued by the Commissioner.
(d) Issuing of Certificates.
(1) Whenever a refrigerating system has been installed or altered under a required permit and such system has been completed in conformity therewith and with the provisions of OBBC and this Building Code and the applicable rules and regulations promulgated thereunder, and has been inspected, tested, and approved by the Commissioner, the Commissioner shall issue a Certificate of Operation to the person, firm or corporation installing or altering such system, for delivery to the owner, authorizing the operation of such system. It shall be the duty of the installer to give twenty-four (24) hours’ advance notice to the Commissioner when such work is ready for test.
(2) A Certificate of Operation shall be issued for a refrigerating system installed prior to June 27, 1949, when such system has been inspected and found to be in safe operating condition.
(e) Revocation. The Commissioner may revoke a Certificate of Operation issued for a refrigerating system whenever the Commissioner finds on inspection that such system is not being maintained in safe operating condition. Notice of revocation may be given in person or by registered mail to the owner of such system or to the person holding a Certificate of Qualification to operate such system. Whenever such notice is given, operation of such system shall cease within the time period specified in such notice and such system shall not again be operated until it has been placed in a safe operating condition and a new Certificate of Operation issued.
(f) Operation Without Certificate Prohibited. Operation of a refrigerating system without a required Certificate of Operation shall be a violation of OBBC and this Building Code and subject to penalties provided by Section 3103.99.
(g) Each Certificate of Operation shall be affixed, under glass, in a location adjacent to the compressor or generator of the refrigerating system.
