Try 2200. Good luck

it gets injected on low side [suction side ] high side your just pressurizing oil container

Typically this means you have sucked a bunch of air into the internal tank, from a vehicle that had a leak perhaps ?. Remove the front cover and locate the internal tank. Close the valve on the center hose connection, remove the hose and open the valve slowly and only partially. You should get a good rush of air (not refrigerant). Try it for about 30 seconds then reset the unit. Repeat if required until unit resets. Once reset the unit will purge its self to the correct pressure.

No rush of air ?, could be a bad high pressure switch, connections on the relay board or a wiring issue. If this doesn't work contact me [email protected]

IF I REMEMBER RIGHT THE TANK WILL FILL UP WITH AIR, BLEED SOME AIR OFF OF YOUR RECOVERY TANK.. GET BACK TO ME AND TELL ME IF IT WORKED.. JAY

This is a common problem of Robinair 34700Z / 347002K & 347112K series machine. So don't worry just do the following, with POWER SWITCH OFF: - 1# Open front panel cover and verify the ISV tank is not overfilled. If full, carefully remove refrigerant manually from ISV tank by pressing tank valve. 2# verify if there is high pressure in the ISV tank. Purge excess air from the tank manually. (Open air purge hose from the ISV tank, then carefully press tank valve as needed to blow out excess pressure from the ISV tank)

After doing all above stapes and your problem still exist then replace air purge solenoid (Air purge solenoid located near the ISV tank and fixed with automatic air purge device). Hope this will solve your problem, if so please vote for it for farther help! Good luck

This is a common problem of Model: 34788, 34788-I, 34988, AC34788, GE48800 etc.
You need to replace air purge solenoid (Air purge solenoid located on top of the ISV tank, if you open front panel cover then you can see it on top of the tank).
After doing above stapes and your problem still exist then you have to replace PCB relay board.
Hope this will solve your problem, if so please vote for it for farther help! Good luck
