Speed is regulated with a rheo- atot. But compressor speed must be adjusted at times to auk ammonia-suc- lion-pressure variations, caused by de gree of freesing ice. We painted a white dot on espoaed surface of compressor drive shaft, sketch. TTila helps know compressor's speed by looking ot it. Slower speed of shaft la easier to judge than much faster rim speed of flywheel. T Trail Catontvillc, Md. four doors have shown no corrosion^ since that time.
