Robinair A/C machine won't work
 

Anyone know about these machines? Just bought a used (barley) Robinair 17800B recovery / recycle machine for my home shop. It was bought from a closed down shop at auction so I am stuck with it so I need to get it working.

All of the fuctions start but does not matter if I am trying to recover, recycle, fill the unit from a fresh tank of 134 I get a HI-P (High Pressure) message and the function stops. Ive checked all the trouble shooting in the manual and talked to tech support at Robinair (They were no help other than offering a number to a repair man)

Ive hoping this is a common issue someone can give some pointers on. It looks near brand new and the run meter only shows 5 lbs of refrigerent has gone though the filter.

thanks in advance

If you don't get a response, PM me. I work for Bosch in the division that includes OTC and robinair, but I'm on the OE specialty tool side of things. I might be able to get you a better contact if the forum doesn't get you what you need.

Thanks a ton! I will give that a try.

Lol i saw your thread on garage journal

I would check the filter anyways. I have heard contaminants can clog the machine really fast if they evacuated something nasty

My recovery machine that I use for commercial hvac has a small screen in the input line, I had a instance where I was trying to recover refrigerant and was getting higher than normal pressures and when I took that screen our and replaced it my pressures dropped significantly. I'd also look for a filter of some sort to clean or replace.
