195. While recharging a commercial type refrigerator, with a hermetically sealed compressor with no pressure gauges, what could you use or do to achieve a proper full charge?

To achieve a proper charge in a hermetically sealed refrigerator without pressure gauges, charge the system until the compressor's running current matches the full-load amperage listed on the compressor's nameplate; this provides an objective measurement in the absence of pressure readings and ensures the compressor operates under design conditions, unlike subjective methods or unsafe overcharging practices.
