N N o o t t e e : : All conditions which do not conform to the
established requirements for unit installation
MUST be corrected prior to start-up. Any non-
conforming condition which is not corrected
prior to start-up must be noted in the Non-
Compliance Form (PROD-ADF001*-EN) by the
start-up technician; this information must also be
signed by responsible site personnel before
start-up and the completed Non-Compliance
Form will become part of the start-up record,
submitted with a Start-up Check Sheet and a
Chiller Service Report.
