Hi,
Breify looked at system not cooling today, its a twin split with a PUH-5... outdoor on R22.
The filters on the 2 cassettes were blocked so washed them out but was getting a P8 (abnormal discharge temp?) fault on the remote.
Put my gauges on the suction schreader, had a head pressure of around 7.5bar, and ran the sytem in test mode. Compressor ran, air off condenser was just ambient, liquid line was sweating, suction was around 1.5 bar. So first thoughts were that it was undercharged. On closing of manifold gauge after adding some vapour, the pressure remained at around 7.5bar again, with the comp still running.:confused:
Could there be a blockage somewhere? The suction service valve is after the 4-way reversing valve if that helps?
