All existing installations of refrigeration equipment, air conditioning
or refrigeration and air-conditioning equipment installed on any premises
and requiring the use of water supplied by the Township water system
or derived from a well shall be subject to the rules and regulations
prescribed in this article.
No new installation of refrigeration equipment, air-conditioning
or refrigeration and air-conditioning equipment requiring the use
of water supplied by the Township or derived from any well shall be
installed on any premises until a permit authorizing such installation
has been issued by the Township Engineer.
Applications, in duplicate, on forms furnished by the Township Engineer for permits for refrigeration, air-conditioning or refrigeration and air-conditioning equipment to be installed shall specify the information requested on the application and shall be accompanied by the fee as provided in Chapter
A565, Fees. One approved copy of the application will be returned to the applicant to serve as a permit.
All installations of any individual or collective system of
refrigeration equipment, air-conditioning equipment or refrigeration
and air-conditioning equipment in any premises for a single consumer
shall be installed under the following specifications:
A. All new installations of any individual or collective system of refrigeration equipment, air-conditioning equipment or refrigeration and air-conditioning equipment of three tons and over shall be equipped with a water conserving device, such as economizer, evaporative condenser, water cooling tower or similar apparatus, which device shall not consume, for makeup purposes, in excess of 5% of the consumption of water that would normally be used without such device, except as provided in §
519-38.
B. All new installations of refrigeration equipment, air-conditioning
equipment or refrigeration and air-conditioning equipment of under
three tons and not using recirculated water shall be provided with
an automatic water-supply regulating device so as to limit the flow
of water in relation to the condenser temperature reduction requirements
of the apparatus. In no case shall the equipment use in excess of
1 1/2 gallons per minute per ton capacity.
C. If two or more units, which in the aggregate total three tons or
more, are installed to serve the same building or premises, said units
shall be subject to the same requirements applicable to a unit or
equipment of three tons or more, as provided in this article.
Each direct water connection to a refrigeration unit, air-conditioning
unit or refrigeration and air-conditioning unit using water for cooling
purposes and which is connected with the Township water supply system
shall be equipped with a vacuum breaker, except in installations where
the water supply piping has no contact with refrigerant. This will
be the case where two substantial and independent wall thicknesses
of metal separate the refrigerant from the Township water supply system.
Refrigerating units, air-conditioning units or refrigerating
and air-conditioning units with a capacity of more than 20 pounds
of refrigerant shall be provided with a relief valve installed on
the outlet side of the vacuum breaker of the water supply connection,
such relief valve being set at five pounds above the maximum water
pressure at the point of installation.
All installations of any individual or collective system of refrigeration equipment, air-conditioning equipment or refrigeration and air-conditioning equipment of three tons and over shall be equipped with a water conserving device as provided in §
519-35. The Township Engineer may permit a diffusion device which will return the water in pure and uncontaminated condition, without loss or waste, back into the ground instead of the device required under §
519-35. If permission is granted for such a diffusion device, it shall be the responsibility of the building owner to ensure that no water is wasted or contaminated thereby. No diffusion well or recharge basin shall be permitted under this section unless it is assured that all water used in such refrigeration or air-conditioning system will be effectively returned in a pure and uncontaminated condition after use to the subterranean sources from which the water is obtained. No connection to storm or sanitary sewer shall be permitted under this section.
