Installation Instructions

Calmat's Quick & Easy Installation

  • The electronic water treatment system Calmat prevents scale and rust deposits in pipes and devices. The unit is installed on the main water supply (e.g. close to the water meter)
  • Calmat will work with all pipe materials including copper, plastic, PVC etc. The setting can and should be set appropriately based on the pipe material the cables are wrapped around and the pipe diameter regardless of the rest of the piping system (which will be treated as well).
  • The electronic control unit can be attached directly on to the pipe. This can be done either horizontally, vertically and even upside down. It may also be mounted on the wall or beam if there is not enough room. It is required is the two impulse cables to be wrapped on the pipe tight and neatly (like the picture below).

Note: electrical impulse cables can be wrapped vertically as well, and the winding direction (clockwise/counterclockwise) does not make a difference.

  1. Place Calmat on the pipe. Install Calmat on the main water pipe and fix the electronic unit with the cable ties.

  2. Now place the red impulse terminal cable in the left socket. Feed the cable to the back of the pipe and fasten with a cable tie. Wind the cable tightly and firmly around the pipe to create a coil. Plug the second impulse tie through the black loop at the end of the cable and fasten it.

  3. Repeat the installation with the second impulse cable again (see 2.).

  4. First connect the adapter with the electronic unit with the socket on the left site of the device. Plug the mains plug into the power socket (permissible voltage: 87 - 260 V, 50/60 Hz). The green control light will light up. The display will show "calmat".
  5. Set up your program:
    Please choose your language with the upper button (>). Then press the button (P) to select the program according to your pipe material and pipe diameter (a,b,c, or d). You can change the program selection at any time later.
