641—14.6 (714) Labeling and manufacturer’s performance data sheet. All water treatment systems must be provided with a label and accompanying manufacturer’s performance data sheet to provide the consumer with clear information on the effectiveness of reducing health-related contaminants from typical water found in Iowa public and private water supplies.
	 14.6(1)  Label. Each water treatment system must bear a conspicuous and legible label stating, “IMPORTANT NOTICE—Read the manufacturer’s performance data sheet.”
	 14.6(2)  Manufacturer’s performance data sheet. The manufacturer’s performance data sheet shall be given to the buyer by the seller and shall be signed and dated by the buyer and the seller prior to the consummation of the sale of the water treatment system and retained on file by the seller for a minimum of two years. The manufacturer’s performance data sheet shall contain information including, but not limited to:
	  a.   	 The name, address, and telephone number of the seller.
	  b.   	 The name, brand, or trademark under which the water treatment system is sold, and its model number.
	  c.   	 Performance and test data including, but not limited to:
	 (1) 	 The list of contaminants found to be reduced by the water treatment system.
	 (2) 	 The test influent concentration level of each contaminant.
	 (3) 	 The percentage reduction or effluent concentration of each contaminant.
	 (4) 	 The maximum contaminant level (MCL) specified in the U.S. Environmental Protection Agency’s national primary drinking water regulations.
	 (5) 	 The approximate capacity in gallons or the period of time during which the water treatment system is effective in reducing the concentration of contaminants based upon the contaminant influent concentrations used for the performance tests. The claimed volume capacity of a water treatment system needs only to be based upon the claimed contaminant most likely to break through into the effluent during the test period.
	 (6) 	 Where applicable, the flow rate, pressure, and temperature of the water during the performance tests.
	  d.   	 The following information must be contained on the performance data sheet or may be referenced to the owner’s manual.
	 (1) 	 Installation instructions.
	 (2) 	 Procedures and requirements necessary for the proper operation of the water treatment system including, but not limited to, electrical requirements; maximum and minimum pressure; flow rate; temperature limitations; maintenance requirements; and expected replacement frequencies.
	 (3) 	 The seller’s warranty limitations.
	 (4) 	 Non-health-related substances may be listed on the performance data sheet but may not be referred to as contaminants.
