5 Preparations at the workplace
5.1 Assembling water supply unit
1. Check that the tank, pump and hose are undamaged before assembly.
2. Connect the hose to the outlet (1).
3. Pump the pressure in the empty water supply unit up to 2 bar (2).
▶ The pressure must not drop by more than 0.5 bar within 30 minutes!
4. Check by pulling the red button of the safety valve (3).
▶ The pressure must be released.
5.2 Filling and preparing water supply unit 3,
1. Pull up the red button of the safety valve until the tank is completely depressurized (1).
2. Push the pump handle down and turn the pump handle counter-clockwise (2).
▶ The pump handle is locked.
3. Unscrew the pump from the tank (3).
4. Pour the water into the tank (4).
5. Check the fill level in the hose.
6. Pass the transparent hose several times from top to bottom beside the tank (5) .
The liquid levels in hose and tank equalize. The liquid level visible in the hose now corresponds to
the fill level in the tank, which you can read from the scale.
7. Screw the pump into the tank (6).
8. Push the pump handle down and turn the pump handle clockwise (1).
▶ The pump handle is unlocked (2).
9. Build up pressure in the tank to approx. 2 bar (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.
10. Push the pump handle down and turn it counterclockwise.
▶ The pump handle is locked.
6 Operation
6.1 Use 5
1. Connect the plug-in connector of the pressurized water tank to the plug-in nipple (1).
2. Actuate the ball valve.
▶ The liquid supply begins.
▶ The liquid quantity can be regulated with the ball valve.
3. When pressure drops below 1 bar, operate the pump again to build up pressure (2).
4. Refill the tank when it is empty → page 10.
6.2 After use 6
1. Pull up the red button of the safety valve until the tank is completely depressurized.
2. Close the ball valve and disconnect the plug-in connector from the plug-in nipple (1).
3. Lock the pump handle.
4. Screw the pump out of the tank.
5. Drain the remaining water from the tank.
6. Wipe off the water supply unit with a damp cloth.
7. Coil the hose round the tank and seat the plug-in connector on the locating pin of the water supply unit
