It is probably to warm. Are you filling it with liquid by turning the tank upsidedown.

SOURCE: robinair model 347002k has a problem with leaving

Please change your machine spin-on filter & vacuum pump oil immediately,becaus you already exceed maximum limit of filte.( NOTE:max.cap.of filter is 150 lbs ) if you keep using machine without changing filter then compressor will get damage at any time. Recovery is not compleating also because of that & do not skip clearing before any recovery.hope this will 100% solve problem.

SOURCE: Can my Robinair 34700Z be set to recharge in

You can not use any Robinair machine in ounces to recharge refrigerant instead of LBS or KG. the software is not programed for count refrigerant in ounces!
Hope you get your answer

Robinair 34700z will only fill 1/2 of recommended refrigerant


Try running the compressor for a while,then see if you can get more into the system on the low side,not the high side while it is running,until the sight glass on receiver dryer clears from being milky.

Hi, my robinair ac375 wonot charge gas, gauge up arrow and down arrow wont move, we done filter and vaccum oil and reset. it is possible to get special way to reset gauge?


mhkamran.jpg Please check Charging solenoid (S3) in Solenoid manifold block, it may need to change solenoid coil or Rebuild. If charging solenoid is OK, then problem can be SCALE or MAIN CIRCUIT BOARD. See if the machine display show default charging weight 90 kg/lbs when you active CHARGE mode. If not then calibrate scale. But if default charging weight is shown then replace MAIN CIRCUIT BOARD. See attached picture to find solenoids. I wish this will help you to solve the problem. If so please vote for it for further assistance. Best of luck!

My 34700z will tell me i have 2 or 3 lbs of freon but when i try to charge even 1/2 it will say insuffecent. how do i reset the machine to get a true reading? thanks


Your machine sound like normal to me! For charging to the vehical you should have minimum 3.30 lbs of refrigerant on ISV tank. However if you wish to re-calibrate the scal,please check with my other solution where i post detail information about scale calibration.
I wish this will help you to solve the problem.

I need to replace the filter in my Robinair 34700Z machine. Where is it located? And where can I find a manual to go with this machine? Mine is missing. . .right when I need it.


Press the main menu key,then upper arrow & go to "Change filter" option,then press "Yes" key & now follow on screen message(Do not skip any option while active ''change filter'' option).
Filter located on back side of the machine & fixed with the manifold assy.it's long black color & you may see the sticker with part no# 34724 (spin-on filter dyer).
For user manual you can try to robinair web official site www.robinair.com
Hope this will help you.

HOW TO CHANGE FILTER just shows clearing filter please wiat


"Clearing filter please wait" if this message is running more then five minute then it's sound that your machine compressor is not haveing 13'' of suction ( Compressor is damage or weak suction) so you have to replace new compressor.Note:every 68 kg/150 lbs of recovering refrigerant you must change spin-on filter,otherwise you will have again same problem.
