FilmTec warrants that its new reverse osmosis elements are free from defects in materials and workmanship. FilmTec's obligation under this limited warranty covers a period not to exceed 12 months from date of receipt by Buyer, provided that such elements are operated and maintained in accordance with FilmTec's published specifications and good engineering practices. FilmTec's obligation under this limited warranty is limited to the repair or, at FilmTec's discretion, replacement of any element which, when examined by FilmTec, appears to be defective under this provision of the limited warranty. Prorated Performance Limited Warranty. FilmTec warrants the performance of its elements for three years from whichever of the following events occurs first: ELEMENT SHIPPED WET. a. First use in system; b. Three (3) months following date of shipment from Minneapolis to a location in the United States, Puerto Rico, Canada, and Mexico; or c. Six (6) months following date of shipment to any other destination. ELEMENTS SHIPPED DRY. (Tap water and brackish water elements only) a. First use in system; b. Twelve (12) months following date of shipment. Initial Performance. FilmTec warrants that the elements herein offered have the initial minimum permeate flow and initial minimum salt rejection as specified in the Technical Bulletin(s). These parameters are established under standard test conditions specified by FilmTec. Should any element(s) not meet performance specifications, and Buyer notifies FilmTec of such deficiency, FilmTec will, upon confirmation of faulty performance, repair or issue credit for the defective element(s). Shipping costs, in such case, will be paid by FilmTec. Performance During Three-Year Limited Warranty Period. During the first three years of operation of the element(s), FilmTec warrants that minimum permeate flow, when operated under standard conditions published by FilmTec, shall be at least 70 percent of the specified initial average flow. FilmTec further warrants that maximum salt passage, when an element is operated under standard test conditions published by FilmTec and pressure required to give the initial rated flow, will not exceed 1.35x the specified maximum value. FilmTec will, on confirmation of loss of performance during the warranty period, credit 1/36 of the original purchase price of the element for each unused month of the warranty period toward the purchase of a replacement element at the current prevailing price. Conditions of Prorated Performance Limited Warranty. The performance limited warranty described in the previous section, Performance During Three-Year Limited Warranty Period, shall be null and void if any of the following conditions are not met: a. The design parameters (array, recovery, etc.) plus instrumentation and other components of the system in which the element(s) are employed shall be consistent with sound engineering practice. FilmTec reserves the right to review system design. b. Feedwater temperature shall be less than 113oF (45oC). c. Feedwater SDI (15 min., 30 psi) shall be less than 5.0. d. Feedwater shall contain no ozone, permanganate, or other strong oxidizing agents. e. The element(s) shall not be exposed to pressure greater than 1000 psi for seawater elements, 600 psi for brackish water elements, and 300 psi for tapwater elements, unless otherwise stated in the product specification. f. Backpressure (where permeate static pressure exceeds reject static pressure) shall not exceed 5 psi at any time. g. The element(s) shall be operationally protected against hydraulic transients (water hammer). h. The element(s) shall be maintained in a clean condition, unfouled by particulate matter or precipitates or biological growth; if scaling or fouling should occur, or normalized element flow decline 1 0 percent, cleaning procedures must be employed in accordance with the procedures as published in a literature piece entitled "Cleaning Procedures for FILMTEC FT30 Elements" (Form No. 609-23010). i. During continuous operation the pH shall be no less than 2.0 nor greater than 11 .0. j. There shall be no membrane fouling by colloidal or precipitated solids. k. Adequate provisions against microbiological contamination shall be incorporated into the system design, as well as into all operating and maintenance procedures. l. The element(s) shall not be exposed during cleaning, or in shutdown periods, to a pH less than 1 nor greater than 12. m. Neither nonionic nor cationic surfactants should be used for membrane cleaning or come in contact with FILMTEC elements. The buyer is fully responsible for the effects of non-compatible chemicals on FILMTEC elements; their use will void the warranty. n. Buyer is responsible for providing the user with adequate system operating and maintenance manuals, operator and supervisor training; ensuring user's ability to perform cleaning and other performance restoration and diagnostic procedures. o.

Elements shipped to FilmTec for warranty examination must be shipped freight prepaid. Elements examined as part of a warranty claim which are found to be performing as warranted will be returned to the Buyer freight collect. Reminders. 1. Permeate obtained from first hour of operation should be discharged. 2. Elements must be in use for at least 6 hours before formaldehyde is used as a biocide. If the elements are exposed to formaldehyde before this period, a severe loss in flux may result. 3.
