This document describes the functions and applications of the IS0714-99 SP0714T XL valve produced by Hayward. The valve can be used for pool water filtration, backwashing, rinsing, waste discharge, recirculation, and winter operation. Detailed instructions are provided regarding valve positions and pump flow direction.
This document is an instruction sheet for the Hayward SP0714T Series Vari-Flo XL Valve. It provides exploded views of the valve components, including parts like the handle pin, non-metallic bearing, cover screw, O-ring, backup ring, shaft seal, spring/washer assembly, and key/seal assembly. The document also includes a performance chart showing capacity per minute in GPM and LPM against pressure drop.
The BACKWASH position reverses flow through the filter to clean it by pumping from the bottom, through the filter, and out the top to waste.
Pipe fittings should be hand tight plus one to 1-1/2 turns maximum, and Teflon pipe tape or Permatex No. 2 sealant must be used.
To drain water from the Vari-Flo, depress and rotate the valve handle to place the pointer on any raised portion of the index hubs at a Winter position.
