OPTIONAL PRINTER INSTALLATION

The micro panel is capable of supplying a printout
of chiller conditions or fault shutdown information at
any given time. This allows operator and service per-
sonnel to obtain data and system status with the touch
of the keypad. In addition to manual print selection,

whenever a fault occurs. Detailed explanation of the
print function is given under Print Key on page 122.
