5. Return Oil Pump control to ‘Auto’ from within the AdaptiView.
Check vane operator and vanes (Service Tool).
1. Use the Service Tool manual override menu to manually override the vane control.
2. Enter targets from 0% to 100% and observe vane operation. At minimum and maximum travel the
operator should not exert any force on the vane assembly, adjust as required.
3. Vane movement is smooth to open/close.
4. Vane movement is reported back to the control panel.
5. Return Vane control to ‘Auto’.
Dry run the starter (Service Tool).
1. Make sure the starter disconnect is safety locked open.
2. Use the Service Tool menu of the control panel to initiate the Starter Dry Run.
3. Observe correct operation of starter contactors.
4. Observe correct operation of transition complete signal (if required).
5. Disable Starter Dry Run when complete.
Remove Power
Disconnect and remove temporary power cord.
B.
Preparation for Start-up.
1. Evacuation and charging
Evacuation leak test. When vacuum has been drawn down to 500 microns to 1000 micons, secure the vac-
uum pump. Wait for 12 hours for a valid vacuum leak test. If the rise in vacuum is less than 500 microns
per 12 hours start-up may proceed.
Charge refrigerant. MAKE SURE THE CHILLED WATER IS FLOWING THROUGH THE EVAPORATOR. Charge
the prescribed amount of refrigerant through the liquid charging valve at the liquid inlet to the evaporator.
Check that all drums contain a full amount of refrigerant. Amount charged lgs and kg.
2. Electrical
Disconnect all temporary power cords, replace all fuses, connect motor leads, make final electrical in-
spection.
Power up the motor starter. Check for control voltage at control panel terminals 1X1-1 and 1X1-17.
Volts
Check current to the oil sump heater.
Amperes
As the oil heats up, finish any operations not yet completed in preparation for starting the unit.
C. Chiller Start-up
1. Make all preliminary checks.
Oil temp, oil level, chilled water flow, chilled water load available (cooling units on) etc.
2. Start the unit
If the phase rotation of the electrical power has not been positively confirmed, the actual rotation of the
motor must be checked. Observe the rotation of the motor shaft through the sight glass on the end of the
motor at the moment of start-up. Rotation must be CLOCKWISE. If the phase sequence is incorrect, con-
firmed by observation of the Phase Reversal diagnostic on the control panel, then the incoming power
leads to the stator must be adjusted by authorized personnel.
As the unit starts and runs, observe closely all operating conditions. Adjust the oil pressure regulator if
necessary to 18 to 22 psi net.
In the AdaptiView Purge Settings menu of the control panel, place the Purge Operating Mode to ‘on’ to al-
low the removal of non-condensables. It may also be necessary to disable the Purge Pumpout Limit timer
found in the Purge Settings menu.
