Safety
Organizational measures Risk of property damage and personal injury from lack of organizational measures
- Use equipment and protective gear suitable for the activity.
Danger of electric shock from live components.
- Prior to working on the electrical system, switch off the unit, disconnect the electrical system from the mains and prevent power from being switched on again. Check to ensure the system is dead.
- Use only insulated tools.
Risk of explosion and fire from improper connection
- Prior to working on the gas system, switch off the unit, close the gas supply from the gas system and secure it against being reopened. When bleeding air or degassing, ensure that the air and gas are discharged to the outside in a technically correct manner and without creating a risk.
