====== Connection to the central water supply system (Touch) ======

This type of connection requires preparation of the water supply system. Direct connection to the water supply is not recommended; typically, 3- or 5-cell filters are used for water purification.


**Attention! Installation of water supply regulation devices is prohibited!**

A 6mm diameter PVC hose is used to connect to the machine's nipple. Ensure that the water supply pressure is at least 0.15 - 0.8 MPa (1.5 - 8 bar).

**Connection procedure:**

  - Connect the PVC hose to the fitting on the back of the machine: {{ :t-wtrlinehole.jpg?nolink&300 |}}
  - Set the water supply switch to the up position: {{ :t-bottletumbler.jpg?nolink&200 |}}
  - Turn the taps as shown in the picture below: {{ :t-wtrlinecran.jpg?nolink&200 |}} 
  - Install a container for waste water.
  - Unwind the fishing line with the {{ :t-wastesensor1.jpg?linkonly |waste sensor}}. float . The float should hang freely into the waste container, and the sensor should be in {{ :t-wastesensor.jpg?linkonly |lower position}}.
  - Start the machine. When you first start it [[error_1_no_water_touch_usa|Error 1 No Water]] will appear on the screen.
  - Press the {{ :t-service_mode.png?linkonly |SERVICE MODE}} and press the {{ :t-pumpingwaterbutton.png?linkonly |"Pumping water"}} button at the machine display. 
  - The machine will begin filling the system. Wait for it to complete. Once the hoses are filled, water will begin flowing through mixer #1 and the hoses into the drain tank.

===== Adjusting the water level =====



  - After priming the system, adjust the water flow. Restart the priming process and check the water level in the mixer funnel (see the image below): {{ :воронка_миксера_уровень_воды.jpg?nolink&300 |}}
  - Adjust the water flow if necessary. This can be done by turning the regulator with a "+" screwdriver: {{ :t-wtrline-regulator.jpg?nolink&200 |}} 
  - To increase the water flow, turn the regulator clockwise; to decrease it, turn it counterclockwise. Check the water level in the funnel.
  - Open the service menu and rinse the mixers by pressing buttons 1-4 on the screen one by one.
  - Press {{ :t-controller_reboot.jpg?linkonly |CONTROLLER REBOOT}} service button. After the machine restarts, make sure [[error_1_no_water_touch_usa|Error 1 No Water]] is no longer displayed on the screen.
  - After setting the water level, check the water output in the {{ :t-conversionfactorscreen.png?linkonly |"ConversionalFactor"}} tab.

The water supply connection setup is complete.

====== Possible problems ======

In some cases, if the water pressure in the water supply system is high, the solenoid valve may not open (the machine displays error 1, and no water is pumped when reset). The solution is to reduce the pressure using {{ :t-wtrline-regulator.jpg?linkonly |the supply regulator}}. If this doesn't work, add voltage (turn clockwise) to the {{ :t-ups-pmp.jpg?linkonly |UPS board}} transistor.
