5 - USE

5.1 - How to prepare the pump and check the seal
- Fill the tank with enough water to ensure that the pump rotor
housing is submerged during operation.
- Screw the outer ends of the flexible hoses securely to the
exchanger to be descaled.
- Connect the power cable to a single-phase 230 V power
supply.
- Switch on the pump and check the seal of the hose fittings
on the exchanger and on the pump. In case of leaks of liquid,
check hoses and fittings and replace the defective components,
if necessary.
- When seal is safe, switch off the pump.
- If necessary, add more acid by referring to the dilution specified
in the data sheet of the product.
5.2 - Descaling
- Switch on the pump.
IMPORTANT: During use, the tank cap should remain open to allow for the passage and elimination of
the gas evolved during descaling. Check that the foam level does not exceed the maximum filling level.
- Periodically move the handle of the flow reverser from one stop to the other. 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 acidic.
