Operating Procedures

Operator Interface

AMC chiller modules, whether they are composed of a
single module or up to 12 modules, are automated systems
that use a main electrical panel to monitor, report, and
modify critical system functions.

Chiller Power Panels

There are two different electrical panels used in AMC
chiller. The main power distribution panel receives power
from the building source and distributes it to individual
modules. The electrical and control panel receives power
from the power distribution panel and provides power to the
individual electrical components in that module.

Panel-Mounted Disconnect Switch
Some AMC chiller systems are optionally equipped with a
panel-mounted disconnect switch installed on the outside
of the power distribution panel (or on each module's high
voltage electrical if the chiller has power supplied to each
individual module). The disconnect switch must be turned
to the OFF position before the panel can be opened for
service. When the panel door is open, the power is
disengaged.

Power Distribution Panels

The power distribution panel receives power from the
building source and distributes it to individual modules. It
also houses a circuit breaker for each module, a phase
monitor, and an optional main power disconnect switch.
