Hayward Navigator Pool Vac Hoses Light Gray Box of 12 - HSLCHK120GR

Sizing Automatic Cleaner Hose Length/Tips on Vacuum RequirementsTo correctly size Hayward automatic cleaners, measure from the skimmer or Vac Lock to the farthest point in the poolThen, add two hose lengths to provide sufficient mobility for the cleaner; Example: A 16’ x 32’ rectangular pool will normally require 8-10 lengths of hose depending on depth and skimmer placementAfter the correct hose length is selected and automatic cleaner installed, use the in-line vacuum gauge to check for proper water flow and adjust to satisfy the formula below:Proper Vacuum = 1” of vacuum x # of hose lengths; Example: A pool using 8 hose lengths requires 8” of vacuum for proper operationIf the vacuum level is too high, adjust the filter system valving accordinglyIn the absence of sufficient valving, use the optional in-line regulator valveImproper vacuum levels can prevent the cleaner from climbing vertical walls in gunite/concrete pools or “sticking” at steps and cornersMaintaining proper vacuum also ensures efficient water flow through the throat for effective cleaningNOTE: For complete installation information, refer to your Hayward automatic pool cleaner’s installation manual.
