The automatic hot-gas defrost system may be programmed into the Unit to occur up to nine different times a day with a minimum of two hours between defrost settings. At start of each automatic defrost cycle, refrigeration compressor will operate for 30 seconds to pump freon out of freeze cylinders evaporator coils. After freon has 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.
