HOSE KIT BLK/BL 1 LEAD 11 CONN (Open Line)

Sizing Automatic Cleaner Hose Length/Tips on Vacuum Requirements

• To correctly size Hayward automatic cleaners, measure from the skimmer or Vac Lock to the farthest point in the pool. 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 placement

• After 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 operation

• If the vacuum level is too high, adjust the filter system valving accordingly. In the absence of sufficient valving, use the optional in-line regulator valve
• Improper vacuum levels can prevent the cleaner from climbing vertical walls in gunite/concrete pools or “sticking” at steps and corners. Maintaining proper vacuum also ensures efficient water flow through the throat for effective cleaning

NOTE: For complete installation information, refer to your Hayward automatic pool cleaner’s installation manual.
