However, some spas may require somewhat higher chlorine concentrations, more frequent super- chlorination and more brushing or manual activity to.maintain the proper pool water quality because of unusual contamination or other adverse conditions. Chemical treatment alone will not produce sanitary spa water. A filtration system in proper operational condition is also required to.attain sparkling clear, polished sanitary spa water.

Spas and pools are designed for recreational and therapeutic use and for physiological and phychological- relaxation These pools are �• not drained, cleaned and refilled after-each use and may include, but are not limited to, these types: Hydrojet circulation, hot water, cold water, mineral baths, air induction systems or some combination of these. Spas and Hot Tubs are shallow in depth and are not meant for swimming or diving. However, these facilities, like swi.mining pools, are closed cycle water systems and shall be designed with complete water circulation, filtration, heating and in some cases, disinfectant and overflow systems integrated with the water circulation system. In most cases, spas equipped with heating devices shall have automatic water temperature controls. A public spa, depending on its size, location and support equipment capacity, can accommodate from one to many bathers. B. Air Induction. Air Induction system is piping and valves of air drawn into hydrojet by vacuum created by hydrojet design. C. Air Injection. Air Injection system means a system activated by a separate air power unit, or blower which forces air into hollow ducting built into the spa floor, bench, or other part of the spa. D. Bather. Means any person using the spa and adjoining deck area for the purpose of therapy water sports or related activities. E. Deck. Deck means those areas surrounding a spa which are specifically constructed or installed for use by bathers. F. Deck, Above Ground.

APPENDIX A CHEMICAL OPERATIONAL PARAMETERS 'These guidelines set forth the suggested operational parameters for the . proper chemical treatment and maintenance of spa waters.. However, some spas may require somewhat higher chlorine concentrations, more frequent super- chlorination and more brushing or manual activity to.maintain the proper pool water quality because of unusual contamination or other adverse conditions. Chemical treatment alone will not produce sanitary spa water. A filtration system in proper operational condition is also required to.attain sparkling clear, polished sanitary spa water.
