Carrier PC211 specifications Machines with Storage Tanks

To Read Refrigerant Pressures during pumpout or leak testing:

1.The LID display on the machine control center is suitable for determining refrigerant-side pressures and low (soft) vacuum. For evacuation or dehydration measurement, use a quality vacuum indicator or manometer to ensure the desired range and accuracy. This can be placed on the Schrader connections on each vessel (Figure 8) by removing the pressure transducer.

2.To determine storage tank pressure, a 30 in.-0-400 psi (-101- 0-2760 kPa) gage is attached to the vessel.

3.Refer to Figure 27, Figure 28, and Figure 37 for valve locations and numbers.

CAUTION ! CAUTION

Transfer, addition, or removal of refrigerant in spring-isolated machines may place severe stress on external piping if springs have not been blocked in both up and down directions.

Machines with Storage Tanks

If the machine has isolation valves, leave them open for the following procedures. The letter ‘‘C’’ describes a closed valve. Valves 9 and 10 on the storage tank are always closed. See Figure 16, Figure 17, Figure 27, and Figure 28.
