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.

We have a robinair cooltech 34700z, looking for directions to change pump oil, can anyone help? thanks


For change vacuum pump oil follow the bellow step: Press main menu then keep pressing up or down arrow key till display show "CHANGE VACUUM OIL" then press "YES" key. Now vacuum pump will run for two minute & stop automatically. When pump stop you just open the oil drain cap and drain all used oil from pump (oil drain cap located outside of the machine near high & low side hose). After draining all used oil replace oil drain cap and fill 5 ounce new ROBINAIR vacuum pump oil then press "YES" key and keep filling oil up to middle of sight glass of vacuum pump. Press "STOP" key to complete the process.

NOTE: Do not over fill the pump & do not use any COMPRESSOR oil on the vacuum pump!
