York YLAA0041 Installation Operation & Maintenance page 4

Traditional chiller maintenance is based upon assumed
and generalized conditions. In lieu 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 lo-
cal Johnson Controls Branch can propose a customized
