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

This is a common problrm of Robinair 34700Z / 347002k & 347112k series machine.so don't worry just do the following :- 1# Verify the ISV tank is not overfilled.if full,remove refrigerant manually from tank. 2# Verify if there is high pressure in the tank.Purge excess air from the tank manually.( Open air purge hose from the tank,then press tank valve as needed) 3#Check the high pressure switch for proper operation,if not then replace high pressure switch.Hope this will solve your problem, if so please vot for it

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
