Please check 1# The compressor suction line with a vacuum gauge & make sure it has 13" HG of suction while you active recover. if not then you need to replace the compressor. 2# Check spin-on filter O rings are fixed properly it may missing or lose, also check filter capacity (amount of refrigerant you have been recover sinc last filter change.every 68KG or 150LBS of recovery you must change spin-on filter)

SOURCE: 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!

You may overfill the ISV tank. #1 Open front cover & close LIQUID valve on the ISV. #2 Disconnect LIQUID hose from tank,then open tank liquid valve (which you close earlier) to reduce some refrigerant manually from the ISV tank. #3 after reduce refrigerant from tank, re-connect everything & switch on the machine. #4 If you still have the same problem then you have to re-calibrate the scal. I hope this will help you

HELLO I HAVE A ROBINAIR 34788, MY UNIT WILL NOT CLEAR THE LINES. I TRIED SHUTTING OFF AND ON , BUT LINES ARE STILL HOLDING PRESSURE. I ALSO CANT RECOVER BECAUSE IT WILL NOT GET PAST CLEARING. THANK YOU


sounds like you need to check the grommet between the motor and the pump. If this grommet connector breaks, the motor will come on but the pump will not work. Turn the unit upside down and look where the motor connects to the pump. Be aware if you can lose your oil while turning upside down unless you cap the port and exhaust. If this is it, go straight to the Robinair web site and you can order one for around $25.
