9.2

CONDITIONS OF INSTALLATION AND NORMAL OPERATION

Startup and operation must occur only under the following conditions:
•
The unit must be completely assembled and intact, i.e. not damaged or tampered with.
•
The silencer must be properly connected to the system piping.
•
The machine must be securely fixed in place.
•
The motor must be connected to a suitable control panel.
•
If installed outdoors, protect the unit against the sun and weather.
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 technicians who handle and install the machine, taking the necessary safety measures and
following the instructions given in this manual.
Danger due to escaping process fluids!
Danger due to overpressure with sudden release of process fluids (injury to the skin and eyes)!
Start the machine only if properly connected.
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;
- open the terminal box only after making sure the power is disconnected;
- take steps to prevent the power from being reconnected.
Danger of suction!
Danger due to negative pressure: sudden drawing in of hair and clothing! Start the machine only if properly connected.
Danger due to seizing of the impeller caused by performance values being exceeded
Use the blower, making sure the operating conditions comply with the values given in the SPECIFICATIONS.
Never operate the unit even temporarily with the inlet and/or outlet port closed.
Install a pressure-relief valve or equivalent circuit that can prevent excessive vacuum and/or overpressure and that enables
compliance with the values given in the SPECIFICATIONS in this manual and the 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 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 is 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.
