    mitsubishi pury



    I have 2 Mitsubishi pury p 400`s connected together freezing up. Master unit runs okay but pipework freezes up, slave unit the accumulator is a block of ice and pipework freezes up.
    Have tried added refrigerant but compressor on slave locks up with liquid.
    Any ideas

    You should recover all refrigerant from both units and weigh in correct amount. Than you can proceed with your troubleshooting further!

    have taken out 69 kg of r410a which is the amount stated on data badge.
    acc inlet temperature on slave is -5.7c
    acc inlet temperature on master is 19.7c
    heat exchanger temp on slave is 15.6c
    heat exchanger temp on master is -2.9
    seems opposite to each other
    mitsubishi says low on refrigerant not sure myself now, could problem be reversing valve?

    acc inlet temp on slave -5.7 on master 19.7
    heat exchanger temp on slave 15.6 on master -2.9
    mitsubishi says low on refrigerant because h/p 13.6 and l/p 2.3 on both units
    could problem be reversing vallve on slave unit?
    any suggestions gratefully received
