b. Turn off the chiller water pumps and pumpout con- denser water.

c. Turn on pumpout compressor to push liquid out of the cooler/condenser/compressor section.

d. When all liquid has been pushed into the economizer/ storage vessel, close the cooler isolation valve 7.

e. Access the CONTROL TEST table on the LID. Select the PUMPDOWN/LOCKOUT screen. From this screen, turn on the chiller water pumps and view the chiller pressures.

f. Turn off pumpout compressor.

2. Evacuate refrigerant gas from the cooler/condenser/ compressor vessel.

a. Valve positions: close valves 2 and 5, open valves 3 and 4.

2.To determine economizer/storage vessel pressure, attach a 30 in.-0-400 psi (-101-0-2760 kPa) gage to the vessel.

3.Refer to Fig. 32 for valve locations and numbers.

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

Transferring Refrigerant into the Economizer/ Storage Vessel Ð These steps describe the method of moving refrigerant from the cooler/condenser/compressor sec- tions into the economizer/storage vessel. This is normally done to prepare for service work on the cooler, condenser, or the compressor components or for long-term chiller shutdown.

d.Close valve 1.

e.Turn off pumpout compressor.

f.Close valves 3, 4, and 6. (All valves are now closed.)

g.Turn off pumpout condenser water.

h.Use the PUMPDOWN LOCKOUT screen on the LID to turn off the chiller water pumps and to lock out the chiller compressor from operation.
