Replacing a Refrigeration Rack Oil Filter

Chad starts by isolating the filter. He does that by closing the bottom of the oil reservoir. He then traces the lines to each oil level regulator and closes each one of those off.

Drainage is the next step. Chad simply uses a hose and drains the oil into a bucket, which relieves pressure. He unbolts everything he can and loosens the mount. That way, he doesn’t have to deal with the trouble of flare fittings. He then removes the old gasket and filter, cleans the oil canister, installs a new gasket, and puts a new filter in.

Chad finishes off the procedure by tightening all of the bolts he loosened earlier. He also opens up the bottom of the oil reservoir and the oil level regulators at the compressors.
