Hi ,

You should stick to your operating manual and follow manufacturer's recommendation . Prior to do anything contact them to acknowledge your proposal with a written reply . 

Note : Make sure you are clear about anti surge system and control .

my 2 cents

Thank you MR Breizh for your support. .

The anti-surge will run the compressor recycling the gas to keep the unit out of the surge limits.

 

I Assume your compressor has not it installed.. ????

 

You must install an anti-surge system as a priority engineer task
