Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
Vibration can be due to problems with the compressor vibration mounts, being short of gas or a blockage in either the refrigeration circuit or the brine cycling system. Can you give me some further information, is the system working ie just noisy, or does it not work?
System is working fine, recently cleaned filters on brine system and heating system. Just more noisy than should be. Seems to coincide with re-pressurising heating circuit and brine circuit. pressure gauge on brine system not working, so cant gauge pressure in brine system
OK well I guess until you know what pressure you have in the brine circuit we cant go further, obviously if you have over pressured the brine circuit this mean more pressure on the pump more noise and likely damage to the system. First port of call sort out the pressure gauge ~ Ian
