If the Clearing the Filter Screen will not dis appear,
then the problem is the compressor.
You can test the compressor using a vacuum gauge
and make sure of the 13" HG of suction.

Let me know how it goes..

I have a Robinair 347002K abnd cannot access anything under defaults. Defaults show as a menu item, but I can not see or select anything else under that heading I tried the 5454 password i saw on another...


You may did not try in the right way! The access code (5454) is 100% right for 347002K/347112K and 34700Z new series machines. If keypad has oil injection button (old series machine) press 8787 on keypad.
However you can try as following: To access the change Defaults menu press 5454 (If keypad has oil injection button old series machine press 8787) on the keypad then press ENTER/START arrow key. Now display will change to "Calibrate Scale". Press up or down key to select option you wish to access from: Set Tank Tare, Output Test, Input Test, Keypad Test. Prepare to Ship. Reset Board Memory etc...

NOTE: DO NOT CHANGE 'SET TANK TARE' OR PRESS 'PREAPARE TO SHIP' & RESET BOARD MEMORY' IF YOU ARE NOT FAMILIAR WITH THIS MACHIN!

Hope this will help you. Good 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!

Robinair model 347002k has a problem with leaving a half pound in the vehicle after recovery. i have to recover again sometimes two or three times. what could be the problem. also the display says replace...


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.
