(a) All compressor-type refrigeration units having standard rated capacities of five tons or less may be equipped with water-cooled condensers, using water from city mains, provided that not more than one unit of capacity so equipped or group of units of total capacity, whether connected singly, in series or in parallel, may be used in one air conditioning system.
(b) All types of cooling devices employing city water directly as a means of heat exchange shall be limited to a maximum rate of five gallons per minute, unless the water is again reused in a manner described in division (a) above, in which case the regulations provided for in connection with compressor-type and absorption-type refrigeration shall govern. For this type of system, the total tons of refrigeration shall be the accumulative capacities of both the direct water heat exchanges and the compressor-type or absorption-type collecting components.
(c) A person using any system consisting of a unit of five-ton capacity or less or a group of units totaling five tons or less is prohibited from using water from mains in excess of two gallons per minute, per ton. Each unit shall be equipped with an approved automatic water regulating device, so adjusted as to limit the use of water under maximum summer conditions to not more than two gallons per minute, per ton.
