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 after 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 CH530 twice in
quick succession. During this
three second period, 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.
