Page 8 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.
