  • Page 38 • By condenser fan When the ambient temperature is low during the air-cooled operation, the condenser pressure (high pressure) will decrease. Accordingly, the low pressure will decrease. In order to prevent this situation, when the high pressure becomes set point or lower, the condenser fan stops to prevent the high pressure from excess dropping.
