Field-installed accessories

Minimum load control —

This option allows additional

capacity reduction for unit operation below the minimum
step of unloading (down to 15% of the minimum unit
capacity). Minimum load control is also available as a
factory-installed option.

Control display access door —

This option provides

easy access to the unit control module through a
see-through door without having to open the control box
panels.

Navigator™ display module —

Provides a portable,

hand held display module for convenient access to unit
status, operation, configuration and troubleshooting diag-
nostics capability. The 4-line, 80-character LCD display
provides clear language information in English, French,
Spanish or Portuguese. The weatherproof enclosure and
industrial grade extension cord makes the Navigator ideally
suited for outdoor applications. Magnets located on the
back of the module allow attachment of any sheet metal
component for hands free operation.

Remote enhanced display —

This accessory kit con-

tains a remotely mounted 40-character per line, 16-line
display panel for unit diagnostics.

Chillervisor System Manager III multi-unit control
—

This accessory allows sequencing of between 2 and

8 chillers in parallel or 2 chillers in series. Pump control is
also provided.

Hail guards —

Sheet metal hood provides protection

against hail and flying debris damage.

Security grilles —

One-in. x 4-in. coated wire grille pro-

tects condenser coil from damage.

Low ambient Motormaster

V head pressure con-

trol —

Permits starting and operating down to –20 F

(–29 C) outside ambient temperature. This control is also
available as a factory-installed option. Requires field-
installed wind baffles, minimum load control, and acces-
sory liquid line solenoid.

Liquid line solenoid kit —

The kit provides a liquid line

solenoid valve (per refrigerant circuit) which causes a

complete liquid line shutoff when the chiller is shut down.
This accessory is required when the medium temperature
brine option or the Motormaster V are used.

Wind baffle kit —

This kit provides a factory designed

wind baffle for applications requiring protection. Field-
installed wind baffles are required when the Motormaster V
is used.

Energy management module —

This module provides

energy management capabilities to minimize chiller energy
consumption. Several features are provided with this mod-
ule 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 storage system interface.

GFI convenience outlet —

The field-installed conve-

nience outlet includes 4-amp GFI (Ground Fault Inter-
rupter) receptacle with independent fuse protection.
Convenience outlet is 115-v female receptacle.

Chilled water storage tank —

Provides additional loop

volume for improved temperature control and chilled water
loop stability. Will provide up to 6 gallons per ton. Heater
supplied (additional 230-1-60 field power supply required)
to protect to –20 F (–29 C).

Vibration isolation —

The field-installed

-in. neo-

prene isolator pads (24-in. x 3-in.) reduce vibration trans-
mission from the compressor through the floor and into
the conditioned space.

BACnet translator control —

The control provides an

interface between the chiller and a BACnet Local Area
Network (LAN, i.e., MS/TP EIA-485).

LON translator control —

The control provides an

interface between the chiller and a Local Operating Net-
work (LON, i.e., LonWorks FT-10A ANSI/EIA-709.1).

Touch Pilot™ display —

The display, when used as an
