Operating Procedures

Operator Interface

All Manhattan™ Gen II Water-Cooled Modular Chiller
units, whether they are composed of a single module or up
to 10 modules, are automated systems that use a client
electrical panel to monitor, report, and modify critical
system functions.

Chiller Power Panels

There are two different electrical panels used in the
Manhattan™ Gen II 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 Manhattan™ Gen II 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 electrical and control panel 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 distributes electricity from
the external building power supply. It also houses a circuit
breaker for each module, a phase monitor, and an optional
main power disconnect switch. See figure below.
