Maintenance

9.Connect a vacuum pump to both the high and low sides of the system through properly sized connections. Evacuate the system twice to 1500 microns, and the third time to 500 microns. Break the vacuum each time with dry nitrogen to 2 PSIG (13.8 kPa).

10.Charge the system with refrigerant. Refer to unit serial tag for refrigerant charge amount.

11.Apply power and operate system. Check for proper operation. Suction and discharge pressures will vary with load conditions and coil efficiency. The low pressure switch will shut the compressor down if the suction pressure falls below the cutout setting. Conversely, the high pressure switch will shut down the compressor if the discharge pressure exceeds the cutout setting. High suction pressure reduces the ability of the refrigerant to cool compressor components and can result in compressor damage. Refer to Table 4.

NOTE

High side gauge port is a liquid line connection. Proper procedures should be followed when installing and removing gauges. A 6-foot (1.8 m) hose can hold up to 3 oz (0.1 l) of refrigerant. Be sure to purge high side to low prior to removal.
