This is a common problem of Robinair 34700Z / 347002k & 347112k series machine.so don't worry just do the following :- 1# May the ISV tank is not overfilled,remove some refrigerant manually from tank. 2# Purge excess air from the tank manually.( Open air purge hose from the tank,then press tank valve as needed to purge air from the tank) 3#Check the air purge solenoid for proper operation.Hope this will solve your problem, Best of luck & vote for my solution!
