Restore System Power
To prevent an unexpected chiller start up when system
power is first restored, implement the appropriate
preventative measure from the following list:
1. If the chiller is equipped with an external Auto Stop
button, disconnect the wire from terminal J2-1 on the
1U4 LLID.
2. 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 1U4 LLID. See

components within the enclosure to ensure that no

supply panels for the chiller equipment.
