Recommissioning ac system

[fessy]

Hi guys

I am looking for advice in re commisioning an industrial ac unit. The system has been emptyied and not been in use for 10 year. What process is the best way to go about bringing it back into service?

When is it needed to be chemically cleaned?

Thanks in advance

has been emptyied and not been in use for 10 year.

Before you go any further down this road, what refrigerant is this system designed to operate on?
What is its history?

Personally I doubt that it will be financially viable to bring a 10 + year old system back in to life, too many things has happened since this system were designed, both in terms of R&D and legislation.

Hi found some new info the equipment was ran up on sept 2011 on 407C gas. there is no gas in the system or oil in the sump is this a simple pressure test and check for leaks and put gas and oil into system?

thanks in advance

An easy task for someone who is f-gas registered.
From your questions I assume that you are not f-gas registered?

it will probably need more than a leak test oil and gas if it has been empty for that amount of time
