Re: rotory compressor gone under vaccum while working
Hi, prijrobert, welcome to re.First ensures the system has charged sufficient refrigerant. If there is no gas, it required leak test and related job. If it is normal, then check the blockage of refrigerant through the circuit such as liquid line drier and expansion valve, also check any service valves whether it is closed.

Re: rotory compressor gone under vaccum while working
ask the company who fitted it if he had a vac pump??
as moideen says- check standing pressure see if theres any gas in it, u need to determine if it was sufficiently charged and proove theres no leak on the system, finally if the strainer gauzes are blocked
