This document is the installation instructions for 1% in. Multiport Valve (30 in. Eclipse Filter)
This document provides installation instructions for the Pentair Top Mount Multiport Valve (1" size) designed for use with 30-inch Eclipse Filter systems. It details specific steps to modify older filter components and install new parts to ensure proper operation.
The guide distinguishes between filters manufactured before November 1, 1995, which require a standpipe modification, and those manufactured after that date, which do not require changes. Key installation steps include cutting the standpipe to specific tolerances, centering the assembly in the tank, installing the overdrain basket and extension, filling with media using an adapter and funnel, and securing the valve on top.
No modification is necessary for filters manufactured after 11/1/95.
The valve will not seal properly or bypass may occur, causing leaking and affecting filtration efficiency.
The standpipe must be cut to a length between 11-1/2 inches and 11-3/4 inches.
