Johnson Controls YORK YMC2 Operation And Maintenance Manual

Conditioned based maintenance
Traditional chiller maintenance is based upon assumed and generalized conditions. Instead of
the traditional maintenance program, a Johnson Controls YORK Conditioned Based Maintenance
(CBM) program can be substituted. This CBM service plan is built around the specific needs for
the chiller, operating conditions, and annualized impact realized by the chiller. Your local Johnson
Controls Branch can propose a customized Planned Service Agreement that leverages real time and
historical data, delivering performance reporting, corrective actions required, and data enabled
guidance for optimal operation and life-cycle assurance. The program includes fault detection
diagnostics, operation code statistics, performance-based algorithms and advance rules-based
rationale delivered by the Johnson Controls Connected Equipment Portal.
Proactive services
Throughout the life of your chiller you can take proactive measures to help prevent breakdowns
and keep your unit in peak condition to prolong its lifespan. Proactive services are a smart addition
to your chiller care program, and supplement existing maintenance.
Time-based proactive services
A variety of factors, including unstable power, extreme ambient conditions, and chilled water
system issues can contribute to increased wear on certain unit components. To help ensure the
system remains reliable, you can replace these components at set intervals before significant wear
occurs. For detailed information on the specific time-based proactive services, along with other
proactive services, refer to YMC2 Centrifugal Liquid Chillers YORK Proactive Service Guide (Form 160.84-
PSG1).
