  Section 675IAC20-5-15. Filters  

Latest version.

  •    (a) Filters shall be designed and constructed so that, after cleaning per manufacturer's instructions, the system can provide the water clarity such that a six (6) inch black disc, placed upon a white background, is clearly visible at the deepest point of the water attraction when viewed from the edge of the water attraction.

      (b) Filters shall be designed so that filtration surfaces can be inspected and serviced.

      (c) On pressure-type filters, a means shall be provided to permit the release of air that enters the filter tank. Any filter incorporating an automatic internal air release as its principal means of air release must have lids that provide a slow and safe release of pressure as a part of its design. Any separation tank used in conjunction with any filter tank must have a manual means of air release or lid that provides a slow and safe release of pressure as they are opened as a part of its design.

      (d) Pressure filters and separation tanks shall have operation and maintenance instructions permanently installed on the filter or separation tank and shall include a precautionary statement warning not to start up the system after maintenance without first opening the air release and proper reassembly of the filter and separation tank. The statement must be visible and noticeable within the area of the air release.

      (e) Piping furnished with the filter shall be of suitable material capable of withstanding one and one-half (1 1/2) times the working pressure.

      (f) Filter components that require servicing shall be accessible for inspection and repair when installed according to the manufacturer's instructions.

      (g) The rate of filtration shall not exceed three (3) gallons per minute per square foot of filter surface unless the filtration system is specifically listed and labeled for use above said rate.
