Operation
• Cut water pressure. Disconnect water supply.
• Prepare the proper and suitable chemical product.
Fill the tank with sufficient descaling solution to ensure that the pump rotor housing is submerged
during use.
Attention! The temperature of the cleaning solution should never exceed 50° C.
• Separate the water inlet and outlet of the installation
• Connect one pump hose to hot water outlet, and one to the inlet.
• Connect the power cable to a suitable 230 Volt single phase supply.
• Open the Tank cap.
During use, the tank cap must be taken off, to allow the passage and elimination of the gas evolved
during descaling. Check that the foam level does not exceed the maximum filling level.
• Switch on the pump.
Only ROMATIC 20: By using the automatic pump equipped with FLOW REVERSER it is possible to attack
scale from both entries of the circuit, with the possibility to programme the duration of descaling and
the flow reversion time. By attacking scale from both sides it is possible to clean piping which is almost
totally obstructed and descaling time is considerably reduced.
• Scale removal can be considered complete when bubbles no longer form in the return pipe and the
solution is still acid.
