This document is an installation, operation, and service manual for the Nautilus™ NS Stainless Steel D.E. Filter. The manual contains important information about the installation, operation, and safe use of the product, which should be given to the owner/operator of the equipment. It warns about the potential dangers and provides instructions for safe operation of the filter. The filter should be properly closed and operated without air in the water system to ensure safe operation. Warning labels should be affixed to the top of the filter and clamp bands at all times, and any missing or damaged labels should be replaced.
The document serves as a comprehensive guide for the Nautilus NS series of vertical grid diatomaceous earth (D.E.) filters. It details how the filter works by using a D.E. coating on vertical grid elements to trap suspended matter from pool water, thereby improving clarity without sanitizing the water itself.
Key operational data is provided for various models in the NS series (NS 24 through NS 72), including flow rates and turnover capacities based on different hours of operation per day. The manual also covers critical safety warnings regarding high-pressure systems, proper installation procedures to prevent tank separation, initial start-up steps involving D.E. charging, and maintenance requirements.
