R404A REFRIGERANT Charging the System: Evacuate the system and interconnecting pipework as page 8 ensuring the service valves are fully open. Allow the evacuated system to draw in the majority of the refrigerant charge. The final charge should be adjusted with the system running. All units are fitted with head pressure control. - Page 18 Min fan speed (0 rpm) and fan cut in pressure 200 psig (13.8 barg) are factory set and not adjustable. NOTE: The condenser fan may stop if the operating pressure drops below 200 psig (13.8 barg) R404A: 210-220 psig (14.5-15.2barg) to achieve this remove sealing plug and insert 2mm or 5/64” allen key into setting screw.
