7. How to overhaul the faults. It should take approximate 3 hours to reach the lowest setting temperature of about 5℃ (or 4 ℃) for an empty unit (assuming ambient temp of 32 degrees centigrade and continuous operation). If not, check the compressor, cooling fans, controller, and sensors. - Page 25 compressor process pipe after the system is charged with refrigerant. 7.4. Running test: After the procedures above finish, turn the unit on. To verify the effectiveness of the repair, monitor the unit, the compressor should automatically stop within + or - 2.5 deg centigrade of the set temperature within approx 3 hours (assuming an ambient temperature of 32℃and the unit is empty).
