Unit Startup
Pre-Commissioning Bump Start Procedure
Note: The following procedure is a requirement prior to the first start of the chiller.
Failure to complete may result in damage to the compressor and void the warranty.
Procedure
1. Complete all control settings.
2. Ensure water flows in the condenser and evaporator are correct according to the
pre-commissioning procedures.
3. Ensure the unit has been charged with the correct amount of refrigerant and oil
and that the oil is the proper operating temperature.
4. Complete a phase rotation test if the voltage is less than 600 volts.
The following checks require TWO personnel to complete. During the bump start
of the compressor, one person will look at the rotor from the rear of the motor
through the sight glasses to determine correct direction. Looking at the sight glass,
the direction will be counter¬clockwise. Do not check the rotation of the motor af-
ter the start sequence has completed as the indication may be incorrect.
5. With the voltage applied to the mains on the starter, place the chiller in Auto
mode.
6. After the pre-lube is complete, let the starter energize the motor, permitting a start.
7. After three seconds, activate the emergency stop by pressing the Immediate Stop
button at the AdaptiView twice in quick succession. During this three second peri-
od, the rotor should be seen to rotate in a counter-clockwise direction.
8. If the direction is incorrect, the 3 phases must be isolated from the power source
and two legs swapped to obtain the correct direction.
