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

Refill A/C


the A/C system will need to be placed under a vaccum of at a min. of -29.5 HG to verify the seal held and removed the water caused by being open to the enviorment (humitiy ) will cause water in the system witch will damage the matter in the receiver dryier. there is a specific amount and proceedure that will need to be followed to the letter to place a precharge, bypass the low pressure cutoff switch. extream cauation should be used as the Hihg pressure gas and fluid is both very hot and extreamly hi . I would really recommend if you dont have experance and licensed take it to the shop and get it done it will be chaeper that a hospital bill and the repairs if you get it sealed up right it should only cost the evac fee normally .5 hrs labor and R134 of about 2 lbs here in Calf, labor at a normal shop on A/C specials are 40.00 and 19.99 per lbs of R 134 BE CAREFUL

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!

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.
