Operation of the Plant
| WARNING |
| for vessels with lid: the agitator can only operate when the vessel lid is closed and secured. The operator (user) must ensure that the agitator can not operate when the vessel is opened for opened vessels: the operator (user) must ensure by means of suitable protection measures that any contact with agitator rotating elements is impossible (Danger of being pulled in) |
|
| ATTENTION |
| The agitator must not be subjected to vibrations when turned off— Risk of damage to the roller bearings and possibly sealing rings |
|
| WARNING |
| During filling, sampling, draining and cleaning there is a risk of contact with product. The product may be poisonous or caustic or otherwise dangerous to health. Dispose of any escaped product correctly. If necessary wear adequate protective clothing and use protective equipment. |
|
| WARNING |
| Too rapid heating up and cooling down may cause damage to the vessel and components |
|
| WARNING 
|
| The system operator shall be responsible for safe operation. A dangerous buildup of electrostatic charge can be caused by stirring the product. Appropriate measures must therefore be taken on site to counteract this |
● Make sure that the heating up/cooling down rate does not exceed 2 Kpm (Kelvin per minute, equal to Celsius per minute)
● Make sure that the filling, draining and sampling takes place via suitable ports
● Make sure that during operation all nozzles remain firmly closed, protective guards remain installed and safety devices cannot be deactivated

| CAUTION |
| Never let the steady bearing run dry |
|
| WARNING
|
| Agitators with steady bearings for use in the explosive area must always be operated with the steady bearing covered with liquid. Dry running is not permitted. |
|
| WARNING
|
| Zone 0: To ensure that the steady bearing is permanently covered with product, failsafe level monitoring must be installed on site (see EN1127-1 or EN 13463-6) Zone 1: To ensure that the steady bearing is permanently covered with product, single-channel level monitoring must be installed on site. |
