Freezer superheat 404a
I started up a 404a walkin freezer. Unfortunately the system was empty and no info as far as the charge. It does have a receiver. I vacuumed the system and filled into the liquid side with solenoid open until pressure equalized. Issue im having is getting the charge set for winter operation. Most what ive read online deals with setting the system up flooding the condenser with a head pressure ...R-404A:Refrigerant for showcases, vehicle-mounted refrigerators, and commercial freezers.
