D. 
Names of manufacturers of the units requiring water.
E. 
Manufacturer's identification and classification of the refrigeration units.
F. 
Manufacturer's rating of maximum refrigeration capacity of the unit or units under the conditions of the planned installation (rating may be stated in tons per 24 hours or in BTU per hour).
G. 
Horsepower of compressor prime mover, if unit is of compressor type.
H. 
Where water conservation devices are required as set forth herein, the manufacturer's name, identification, classification and size of the conservation equipment.
I.

Systems with a capacity in excess of 1 1/2 tons (per 24 hours) shall not use water directly (or indirectly, except when used with conservation equipment) from the public supply. All such systems shall be equipped with evaporative condensers, cooling towers, spray ponds, or other water conservation equipment, the piping in connection therewith to be arranged to prevent any back siphonage into the public water supply system. Systems with a total capacity not exceeding 2 1/2 tons (per 24 hours) may use water directly from the public supply at a rate not exceeding 2.1 g.p.m. per ton if the water temperature is 750° F., provided they are equipped with an automatic regulating valve which will
A. 
Stop the flow of water when the refrigerating machine is shut down.
B. 
Throttle the flow of water down to the momentary requirements of the system.
All systems having total capacities exceeding 2 1/2 tons (per 24 hours) shall be equipped with evaporative condensers, cooling towers, spray ponds, or other water-cooling equipment, unless otherwise approved. This equipment shall be of sufficient capacity to insure conformance with the requirements in the following table for make-up water when operating under full loading at maximum summer temperatures:
