5 Preparations at the workplace
5.1 Assembling water supply unit
1. Check whether the tank, pump and hose are undamaged before assembly.
2. Connect the hose on the drain opening [1].
3. Pump up the empty water supply unit to 2 bar [2].
◁ The pressure must not drop by more than 0.5 bar within 30 minutes!
4. Pull the red button of the safety valve for checking [3].
◁ The pressure must be released.
5.2 Fill water supply unit
1. Fill the water into the tank [1].
2. Check the fill level on the hose [2].
3. Route the transparent hose several times on the tank from top to bottom [3].
◁ The liquid level in the hose and tank are equalized. The liquid level visible in the hose then matches
the filling level in the tank, which you can read off on the scale.
5.3 Preparing water supply unit
1. Screw the pump into the tank [1].
2. Press the pump handle downward and turn it clockwise [2].
◁ The pump handle has been released.
3. Generate a pressure of approx. 2 bar in the tank [3].
◁ The maximum pressure should not exceed 6 bar (red line on the pressure gage). If the maximum
pressure is exceeded, the safety valve is actuated and releases the excess pressure.
4. Press the pump handle downward and turn it counterclockwise.
◁ The pump handle is locked.
