Inspection after approx. 740 operating hours / max. 1 month: 
 
Take an oil sample from the oil tank and analyse it for solid and 
suspended matters, water content, shadings and air bubbles.  
Analyse oil purity of the oil sample. Clean or exchange the oil, if 
required, in an appropriate operating mode. 
 
 
Inspection after approx. 8000 operating hours / max. 1 year: 
 
Take an oil sample from the oil tank and analyse it chemically.  
If required, clean or change the oil during an appropriate operating mode. 
 
Check and retighten, if necessary, the electric connections of the I/H 
converter.

Shutdown 

 

 

If the I/H converter is switched off for reasons of repair, inspection or 
unit shutdown, switch off  the oil supply system and relieve all pressure 
reservoirs, if effective. Switch off the 24 VDC supply voltage and 
remove the lines as well as piping and hose connections. Doing so, a 
considerable oil quantity may leak out. Collect the oil in a suitable 
container and deposit it properly. Close all holes. Now clean and pack 
the I/H converter. 

 

 

Disposal 

 

In the event of disposal of the I/H converter, observe the local applicable 
regulations regarding the environmental protection. The I/H converter 
essentially contains steel, copper, synthetic materials, electronic 
components and residual oil.
