More Refrigeration pipe stolen

[langy]

Fitted several Hitachi IVX systems in the summer.
Got a call the other day from customer letting us know that some scumbags had been on the roof and stolen the exposed pipe and cable.
I think the pipes were open for about 3-4 days.
They have been sealed now until I can get there to replace them.
What's the minimum steps required, obove nitrgen blow through and mega vaccing, after pipe replacement ?
Thanks in advance.

Best you change the oil on any systems that have been open to atmosphere for any length of time, this may involve taking the compressor out & tipping it over to drain the oil out. If you do this be gentle though & prob best you don't tip it completely up-side down...

Ginge :)
