Factory-installed options
Hydronic pump package — This option adds circulat-
ing pumps, complete with controls, contactor, and insu-
lated expansion tank. Available in single or dual (lead/lag
controlled) cooler pump versions, with total dynamic head
external to the chiller from approximately 15 to 75 feet.
Low ambient protection package — Cooler heaters
provide protection from cooler freeze-up to –20 F (–29 C).
Includes low ambient protection for optional hydronic
package, when provided.
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 sig-
nal, 2-point demand limit control (from 0 to 100%) acti-
vated by a remote contact closure, and discrete input for
“Ice Done” indication for ice storage system interface.
GFI convenience outlet — The factory installed con-
venience outlet includes 4-amp GFI (ground fault inter-
rupter) receptacle with independent fuse protection.
Convenience outlet is 115-v female receptacle.
Low-ambient Motormaster® V control — This option
permits operation of the 30RA units down to –20 F
(–29 C) outdoor ambient temperature. The control is also
available as a field-installed accessory. Also requires
field-installed wind baffles, minimum load control, and the
liquid line solenoid accessory.
Non-fused disconnect — This option provides non-
fused disconnect capability for power and control located
at the unit.
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, depending on unit size). Minimum load control is
also available as a field-installed accessory.
Condenser coil options — These options are available
to match coil construction to the site conditions for the best
durability. Refer to the Environmental Corrosion Protec-
tion white paper for more information.
Security grilles — One-in. by four-in. coated wire grille
protects condenser coil from damage.
Medium temperature brine — This option permits
supply liquid temperatures to be set from 15 F (–9.4 C) to
40 F (4.4 C). Refrigeration circuit components, such as the
expansion device, are modified at the factory to adjust for
lower refrigerant flow rates. The use of this option also
requires the addition of the Motormaster V low ambient
control, field-installed wind baffles or accessory wind baffle
kit, minimum load control, and the accessory liquid line
solenoid.
