Fault Condition And Maintenance; Residual Risks - FPZ SCL K09R MD-GOR Betriebsanleitung

Danger of burns caused by contact with hot surfaces of the unit
In operation, in conformity with the values given in the "SPECIFICATIONS" and 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." on the system control and the unit's control elements.
•
Allow the unit to cool!
•
Wait until the unit has completely stopped, i.e. that the impeller and transmission coupling 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.
•
Follow the maintenance instructions in this manual.
Danger due to rotating parts: cutting or shearing
The rotating impeller can be accessed through the openings of the body and cover of the machine, once the manifolds or blind flanges
are removed.
Never put hands or anything through these openings.
Danger due to rotating parts: cutting or shearing
The transmission coupling can be accessed from the electric motor and blower connection flange after the cover plates 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, which 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
- Arrange the use of PPE
- Insulate the place
