8) Switch on the pump and circulate water in the system for approximately
2 minutes to remove the rough deposits present in the pipes.
9) Repeat the pre-flushing to right and left until dump water is free from
rough deposits.
Power flushing with chemical (ROCLEAN RESTORER)
To power flush the system with the chemical (Long Life 800), operate as
follows:
1) Make sure the ends of the flexible hoses are connected to the system
to be power flushed.
2) Make sure that the overflow hose is connected to a suitable drain.
3) Make sure that the power supply cable is connected to a single-phase
230 V / 50 Hz socket.
4) Close the mains water inlet supply tap and close the dump.
5) Make sure that the tank cap is open to visually check fluid level in the
tank.
6) Set the valves as per Figure 3 and add the chemical into the tank.

9) Circulate the chemical in the system circuit for approximately 5-10
minutes.
10) Repeat the power flushing operations switching the flow to right and
left, until the colour of the flushing solution changes, for a minimum
working time of 2-3 hours.
Rinsing with water
To rinse with water after power flushing, operate as follows:
1) Make sure that the overflow hose is connected to a suitable drain.
2) Make sure that the power supply cable is connected to a single-phase
230 V / 50 Hz socket.
3) Make sure that the tank cap is open to visually check water level in the
tank.
4) Open the dump.
5) Set the valves as per Figure 5, open the clean water inlet tap and
switch on the pump.

8) Switch on the pump and circulate water in the system for a few
minutes to remove the flushing residues present in the pipes.
9) Measure conductivity of the mains water at the inlet and dump water
at the outlet.
10) Repeat the rinsing operations until the dump water runs clear.
Chemical filling (ROCLEAN INHIBITOR)
1) Close mains water supply tap.
2) Close dump
3) Set the valves as per Figure 7.
4) Add chemical (corrosion inhibitor and/or biocide-sanitizer) into the
tank.
5) Switch on the pump for a few minutes.
