Robinair Model-34700Z scal calibration follow as bellow:
Press main menu then press up or down arrow till scree appear ''CHANGE DEFAULT'' then press 5454 from the keypad & then YES key (passwoed to access default option).Once you enter to default menu,go to "SCALE CALIBRATION" & then press YES key. now follow the on screen text. Once you calibrate scale then press STOP key to exit.
NOTE: You should have 9KG/20LBS of weight for scale calibration. Do not change ''TANK TARE'' or any other setting it must be on factory setup.

I have a 34134z that will not recover or charge


You may need to replace compressor. Open compressor test port (located on one of the pipe line which come to compressor from top of spin-on filter) and fixe a vacuum gauge on it. press recover from menu and check compressor suction for 13''Hg. If compressor has no suction then its need replace.
NOTE : if you do not have a vacuum gauge then after opening cap from test port, press recover from menu and then gently press small valve on test port with a small L-key to feel suction of compressor. if the compressor discharging air instead of suction, replace compressor.

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!

ROBINAIR 347002K WON'T INJECT OIL


I think you'v try to inject the oil from ''WRONG'' side,as you say RECOVER/VACUUM which is LOW side manifold valve. You should inject the oil from HIGH side ( Turn the high side valve to CHARGE/OIL INJECT after vacuuming & low side vulv to CLOSE possition ) with pressing F1 key. once you press it then hold the key as long as you wish to inject the oil. If you try this way & you still have problem with oil injection then you may need to check oil injection CHECK VALVE or oil injection SOLENOID ( Both located under Hidg side panel mountin valve). NOTE: UV Dye is not a problem for oil injection! I hope this will help you to solve the problem,Good luck. Don't forge to vote for my solution!

I have a Robinair 34134Z It will not recover freon It has 22HG suction The solenoid is working properly Auto freon goes back through the valves to the solenoid and the suction pulls 22 hg at the solenoid...


Please check the following: 1# Check the recovered amount of refrigerant since the last filter change(Max.filter cap.150 LBS/68 KG).If more then this you must change spin-on filter & vacuum pump oil.2# Check with vacuum gauge on compressor test(During compressor running) port & make sure it has 13"HG of suction,If suction less then 13''HG then you have to replace the compressor.3# Check all tank hose (Vaipor,Air purge & Liquid) is connected on the ISV tank quick seal.(Do not over tight).Hope this will solve your problem.
