Periodical Maintenance And Troubleshooting; Replacing The Sound Absorbing Material - FPZ SCL 10DL-MD MOR Instructions

Variations in normal working conditions (increases in power absorption, abnormal noise, vibration, excessive overheating of the service
fluid) are indications of a unit malfunction.
Also, compare the measured values with those given in the "SPECIFICATIONS.
B) With the unit stopped and cooled, periodically carry out the following checks:

Dust: check and remove deposits from the external surfaces of the unit.

Suction filter (if fitted): every 10-15 days, check and clean or replace the filter cartridge. The dirty cartridge will create strong
suction resistance and consequently a higher pressure differential, power absorption and operating temperature.
Danger due to high temperatures!
To limit the formation of surface layers of dust that can affect the natural heat exchange between the unit and the environment, ensure
regular cleaning and removal with suitable equipment.
The suction and/or delivery pipes must not be dirty or clogged! Wear suitable PPE.

13.2 PERIODICAL MAINTENANCE AND TROUBLESHOOTING

Refer to the following section, "OPERATION PROBLEMS", to identify possible critical situations and types of failures.

In case of periodical maintenance for cleaning and replacement of some components, as well as in case of failure, it is necessary
to disconnect and remove the machine from the system.
Danger due to electricity.
Before carrying out any operation, make sure the machine is NOT powered.
Risk of injury due to shearing, crushing, entanglement.
During work on the unit there are risks of injury due to shearing, crushing or entanglement!
Therefore it must be carried out by qualified personnel who handle and install the machine, taking the necessary safety measures and
following the instructions given in this manual.
Danger due to residual negative pressure or overpressure.
For residual overpressure: possible release of process fluids with risk of injury to the skin and eyes;
For negative pressure: possible drawing in of hair and clothing.
Disassemble the machine only after closing and draining the system connected to it.

13.3 REPLACING THE SOUND ABSORBING MATERIAL

When replacing the sound absorbing material in the silencers, proceed as follows:

Undo the screws (1)

Remove the sound absorbing material from the silencer housings (2)

Replace the sound absorbing material and assemble by proceeding in
reverse order.
