Fault Condition And Maintenance; Residual Risks - FPZ SCL R20-MD GOR ATEX Manual De Instrucciones

Install a limiter valve or equivalent circuit able to prevent excessive vacuum and/or overpressure and that enables compliance with the
values given in the "SPECIFICATIONS" and the electric motor RATING DATA.
Turn the unit off immediately in case of any abnormal impeller noise! Then schedule maintenance.
Danger of burns caused by contact with hot surfaces of the unit
In operation, in conformity with the values given in the "SPECIFICATIONS" and the electric motor RATING DATA, the blowers /
exhausters can reach high surface temperatures.
Use suitable PPE against the risk of burns. (Also see the section residual risks)
9.3

FAULT CONDITION AND MAINTENANCE

Before starting routine maintenance on the unit, or for a fault, take the following safety measures:

Disconnect the unit from the power supply via the main the switch.
"

Place a sign: DANGER! Maintenance work in progress."

Allow the unit to cool!

Wait until the unit has completely stopped, i.e. that the impeller and transmission coupling (where foreseen) are not rotating,
checking the electric motor fan.

Ensure the absence of vacuum or overpressure in the unit and in the piping to be disconnected and that no fluid can escape from
the unit and/or system.

Read the maintenance instructions given in this manual.
Danger due to rotating parts: cutting or shearing
The rotating impeller (where foreseen) can be accessed via the openings of the body and/or cover of the machine, once the manifolds,
silencer housings or blind flanges (where foreseen) are removed.
Never put hands or anything through these openings.
Danger due to rotating parts: cutting or shearing
The transmission coupling can be accessed once the covers are removed.
Never put hands or anything through these openings.
Danger due to electricity
Improper behaviour can cause serious accidents.
Work on the electrical equipment must only be carried out by qualified and authorised electricians.
Before starting work on the unit or system, take the following precautions:
- disconnect the mains power;
- take steps to prevent the power from being reconnected;
- open the terminal box only after making sure the power is disconnected.

RESIDUAL RISKS

When designing the machines or systems on which the blower is to be installed, the following residual risks must be considered.
Danger due to hot surfaces!
In operation, the unit may overheat, exposing the operator to contact with hot surfaces
- Indicate the danger
- Use protection devices to prevent contact
Danger due to noise from the unit!
Some machines can produce high noise levels, even exceeding 80 dB(A).
The reference values are given in the "SPECIFICATIONS" and do not consider environmental reverberation.
Protection measures:
Check the actual sound pressure of the machine in the place, and if necessary:
- Report the foreseen noise risk
