Installation
  • Refer to Technical Area for installation guide.
  • Do NOT install Limiting Valve in the ground.
  • Do NOT apply heat near valve during installation.
  • Install so that both hot and cold supplies are balanced.
  • Can be installed in any orientation. For external application, cartridge must be at bottom.
  • Must be installed with correct Expansion Valve fitted down stream of a limiting valve.
  • To adjust outlet pressure use large Philips/Pozi screw driver, turn adjusting screw clockwise to increase (1 turn = 60 kPa [9psi]).
Removable Cartridge
  • All valve seats are contained within cartridge.
  • No need to remove body from valve train.
  • Unscrew cartridge to replace or clean filter.
  • Removal of cartridge will not affect set pressure.
Servicing
  • Filter must be cleaned regularly.
