been pumped out of freeze cylinders evaporator coils, No. 1 freeze cylinder only will go into defrost for approxi-
mately 7 minutes and then will return to normal operation. This ends automatic defrost cycle of No. 1 freeze cyl-
inder. No. 2 freeze cylinder will defrost 30 minutes after the start of No. 1 freeze cylinder. The next automatic
