Hi,
We are discussing the best practices when it comes to using pump down cylinders. For years we have used pump down cylinder to reuse refrigerant in the case where it is still clean within a system. For example a liquid line solenoid needs replacing. We will fit a 1/4 drier in line with the recovery unit to pick up and debris.
My question is, is it ok to use the same pump down cylinder from job to job so long as you follow ensure it is only for the same clean refrigerant type?
What is your pump down cylinder practice?
Thanks.
