9  Start Up. Operation & Shut Down of the SIHIdry

 

Vacuum Pump

 

 

9.1  Preparation

 

 

The pump system must be installed according to the instructions in chapter 8 Installation of The 
SIHIdry Vacuum Pump 

 

9.2  Personal

 

 

Warning!  Risk of injuries may occur due to untrained 
personal. 

 

Unauthorized and / or untrained person may get injured 
during installation preparation and work 

 

Therefore: 

Only authorized personal. 

Use original spare parts. 

Use only the accessories approved by the 
manufacturer. 

 

9.3  Safety

 

 

Warning!  Risk of burning due to hot surfaces. 

Therefore: 

Before starting any activity, ensure that all 
components are cooled down to the ambient 
temperature or 

Wear protective work clothing and safety gloves 
when working near hot components. 

 

Surfaces of inlet, outlet pipes and pump casing may be hot. 
The operating company of the device must ensure that the 
corresponding sign is affixed. 

 

 

 

Warning!  Pre-Check Pump Safety. 

Therefore: 

Check the filling height of the cooling water circuit. 

If explosive, toxic, hot or corrosive gases and vapors 
are handled it must be ensured that personnel and 
the environment are not endangered. 

The electrical connection for the pair of motors (pay 
attention to the correct direction of rotation) must be 
carried out in such a way that the vacuum pump can 
only be switched on after release by the Purge 
Control.
