Before Restoring System Power
1. To prevent an unexpected chiller start up when system
power is first restored, implement the appropriate
preventative measure from the list below:
a. If the chiller is equipped with an external Auto Stop
button, disconnect the wire from terminal J2-1 on the
1A13 LLID.
b. If the chiller is not equipped with an external Auto Stop
button, disconnect the factory installed jumper wire end
from terminal J2-1 on the 1A13 LLID.
Note: EAS = External Auto Stop circuit.
2. Perform a final inspection of the control panel enclosure
before restoring system power.
a. Remove any tools and use a shop vacuum to remove
any dirt or debris that may have been created during the
installation process.
b. Confirm that all upgrade kit wiring has been correctly
routed and that all terminal connections have been
properly made.
c. Inspect the rest of the electrical wiring and components
within the enclosure to ensure that no wiring
connections were accidentally loosened or
disconnected during the kit installation process.
d. Close and latch the control panel door.

supply panels for the chiller equipment.
2. Warn all personnel in the area that system power is about
