.2 Design pressure 2070 kPa [300 psig].
.3 Acceptable Products: Anaconda
34.16 Install the following accessories:
.1 Ball check isolating valves at receiver sight glass.
.2 Charging valve for high and low side filter drier, solenoid valve and thermostatic
expansion valve.
34.17 Refrigerant Tests
.1 Each refrigerant system shall be tested as follows before operation with dry nitrogen
gas to a pressure not less than 1.5 times the system working pressure. During the
test, each joint shall be tested for leaks with a solution of soap and water.
Compressors with refrigerant holding charge shall remain isolated from system.
.2 The system shall then be evacuated to not less than 33.25 Pa (250 microns)
absolute and left for 24 hours, during which time the pressure shall not have
increased more than 33.25 Pa (250 microns). The system shall then be pressurized
to 14 kPa [2 psig] with refrigerant to be used and shall be evacuated to 66.5 Pa [500
microns] absolute and then shall be immediately fully charged with the refrigerant to
be used in the system and each joint checked with an electronic testing device.
Tests shall be performed before insulation is applied.
.3 All damaged or defective components shall be replaced with new (not reconditioned)
components.
34.18 Start-Up and Adjustment
.1 Provide necessary instruments, gauges and testing equipment required. Adjust
controls, to obtain design requirements and manufacturer's ratings.
.2 Test and record cooling apparatus entering and leaving air temperatures, dry bulb
and wet bulb.
.3 Test and record voltage and running amperes and compare to motor nameplate
data, and starter heater rating against design requirements.
.4 Ensure that refrigerant temperatures are accurate to within 0.5
o
C [0.9
o
F] of design
requirements.
.5 In cooperation with controls contractor's representative, set and adjust automatic
control system to achieve required sequence of operations.
.6 Bring equipment into operation, trial run and make up any loss of oil and refrigerant.
.7 Test reports to be submitted for review and inclusion in Maintenance Manuals.
