View Full Version : pury p400 freezing up

16-03-2016, 06:59 AM
I have 2 pury p400`s connected together. The master runs fairly well but the slave is freezing up badly. It has all the symptoms of being short of refrigerant but when I add refrigerant the slave compressor locks up. The master will run at 80psi suction when the slave is tuned off.The slave will run at 50 psi suction, 200 psi discharge when the master is not running. The unit displays a communication error on the control panel.
Mitsubishi tells me it is low on refrigerant. If I put to much refrigerant in it locks up the slave but the master still runs okayish.
