      (2)    "Ton of refrigeration" means the amount of heat required to melt a ton (2,000 lbs.) of ice in twenty-four hours, and corresponds to heat removal of 12,000 btu per hour or 200 btu per minute.

   (b)    Installation Permits; Fee. No person, firm or corporation using City water shall install or use for air conditioning purposes any equipment which uses water supplied by the City Water Department without having procured a permit from the Superintendent of Water, and the payment therefor, shall be ten dollars ($10.00), nor shall any person, firm or corporation engaged in the business of installation of air conditioning units, install for air conditioning purposes any equipment which uses water supplied by the City Water Department without having inquired of the owner or his agent and ascertained that a permit has been procured for such installation.
