Navigator™ module provides a portable, hand-held dis-
play for convenient access to unit status, operation, config-
uration and troubleshooting diagnostics capability. The
four-line, 20-character LCD (liquid crystal display) display
provides clear language information in English, French,
Spanish, or Portuguese. The Navigator module features an
industrial grade extension chord and magnets located on
the back of the weatherproof enclosure to allow attach-
ment to sheet metal components for hands free operation.
BACnet™ translator control provides an interface
between the chiller and BACnet Local Area Network
(LAN, i.e., MS/TP EIA 485). The BACnet translator con-
trol is also available as a field-installed option.
LON translator control provides an interface between
the chiller and Local Operating Network (LON, i.e., LON-
Works FT-10A ANSI/EIA-709.1). The LON translator
control is also available as a field-installed option.
Energy management module provides energy manage-
ment capabilities to minimize chiller energy consumption.
Several features are provided with this module including
leaving fluid temperature reset, cooling set point reset or
demand limit control from a 4 to 20 mA signal, 2-point
demand limit control (from 0 to 100%) activated by a
remote contact closure, and discrete input for "Ice Done"
indication for ice stage system interface.

The 300 psig (2068 kPa) evaporator operating
pressure option allows operation for water-side pressure
up to 300 psig (2068 kPa).
The 300 psig (2068 kPa) condenser operating
pressure option allows operation for water-side pressure
up to 300 psig (2068 kPa).
Minimum load control allows additional capacity reduc-
tion for unit operation below the minimum step of unload-
ing via hot gas bypass.
Marine waterboxes provide water piping connections
extending from the side of the waterbox (as opposed to
extending from the end of the waterbox). This option also
includes a removable bolt on waterbox cover allowing
access to the heat exchanger tubes without breaking the
existing field piping. This option is available for both the
evaporator and condenser.

Flanged connection option  provides  an  ANSI  (Ameri-
can National Standards Institute) flange on the end of the
chiller water piping for connection to a customer supplied
mating flange in the field piping. This option is available
for both the evaporator and condenser.

One-pass evaporator provides a lower pressure drop
through the evaporator for applications with low delta T
(temperature) or high flow or where the evaporators are
piped in a series or side stream arrangement. One-pass
evaporator is only available with flanged connections and
with discharge end leaving water connection.
Three-pass evaporator provides a greater efficiency for
brine applications and in applications with a high delta T
and low flow. Three-pass evaporator is only available with
flanged connections.
Heat machine condenser allows operation with up to
140 F (60 C) leaving condenser water temperature (see
E-CAT for selections). In addition, this option provides
factory-installed thermal insulation on the condenser,
condenser flow switch and leaving condenser water
