Instructions

GENERAL REQUIREMENTS FOR NUT AND FAUCET:

  1. Made of solid metal material instead of plastic
  2. Usage of any lubricant on threads is not allowed
  3. No sharp or burry sections at sealing surfaces
  4. Recommended tightening torque is relevant to brass-brass connection with 1.5 mm thread pitch
  5. Design to suit drawing dimensions.
  6. Residues of auxiliary material used for soldering fittings can damage the base, keep the surface clean.
  7. The inner diameter of the clamping nut according to the data sheet is, this is the factor influencing the operation of the HWS ring! It is important that the clamping nut completely supports the cartridge neck or HWS ring in the whole diameter.
  8. Proper lever design is important. 3D Mechanical CAD systems can show the weight and center of gravity of the designed lever, Thus, the torque due to the weight of the lever can be easily calculated in the installation position. Compared to the opening and closing torque data of our cartridges, self-closing and opening can be easily avoided.
  9. K-25 OP: There is no tightening torque regulation use the required clamping zone.
  10. PB-40, K-28 StopGo: Requires check valves
  11. NKJ, KJ cartridges: Hot/cold water inlet connections must be reversed.

ADJUSTMENT OF THE HOT LIMIT RING

  1. When the cartridge is supplied the hot limit ring is in the middle position.
  2. To save hot water and to avoid scald the ring can be turned. In this case the pin of the ring is bumped against the stop around the cartridge, before we can reach the full hot water position by turning the handle of the faucet.
  3. The adjustment of the ring is as follows (see the attached drawing):
    1. The hot limit ring must be removed from the cartridge.
    2. The ring must be turned clockwise up to the requested point.
    3. The ring must be re-positioned onto the cartridge.
  4. Maximum flow rate can be adjusted by a grub screw located in the lever.

CHEMICAL RESISTANCE OF CARTRIDGES

  1. From product compliance point of view, none of the Plumbing products referring regulations /standards, cartridges relevant requirements address any chemical resistance requirements. With regard to the intended application of the cartridges of which function is drinking water regulation, Kerox has no procedures in which suitability in chemical environments is assessed. On the grounds that, we cannot rate the chemical resistance of the cartridges.
  1. However based on the experience of the past few years, we can say securely, that we do not suggest the use of aggressive detergents (strong acid or alkali) under any circumstances. These cleaning agents getting into the cartridge can release the grease between the ceramic disks, stronger purifiers can even destroy the plastic parts of it too. We rather suggest the cleaning with soapy water or with gentle detergents (e.g. with light citric acid). We recommend faucet manufacturer to protect the cartridge to develop such a faucet design that prevents cleaning agent from getting into the cartridge.
