cated in the Microprocessor Panel to accept a eld
provided control power circuit with appropriate branch
circuit protection in accordance with applicable Local
and National codes. For Models 0218 - 0418.
D. Condenser Coil Environmental Protection:
1. PRE-COATED FIN CONDENSER COILS – The
air-cooled condenser coils are constructed of black
epoxy-coated aluminum ns. This can provide cor-
rosion resistance comparable to copper-n coils
in typical seashore locations. Either these or the
post-coated coils (below), are recommended for
units being installed at the seashore or where salt
spray may hit the unit.
2. COPPER FIN: Provide copper ns in lieu of alu-
minum.
3. POST-COATED EPOXY DIPPED CONDENSER
COILS – The unit is built with dipped-cured con-
denser coils. This is another choice for seashore
and other corrosive applications (with the excep-
tion of strong alkalies, oxidizers and wet bromine,
chlorine and uorine in concentrations greater
than 100 ppm).
E.Protective Chiller Panels (Factory-mounted):
1. Louvered Panels (condenser coils only): Painted
steel as per remainder of unit cabinet, over external
condenser coil faces.
2. Wire Panels (full unit): Heavy gauge, welded wire-
mesh, PVC coated to resist corrosion, to protect
condenser coils from incidental damage and restrict
unauthorized access to internal components.
3. Louvered Panels (full unit): Painted steel as per
remainder of unit cabinet, to protect condenser coils
from incidental damage, visually screen internal
components, and prevent unauthorized access to
internal components.
4. Louvered/Wire Panels: Louvered steel panels
on external condenser coil faces, painted as per
remainder of unit cabinet. Heavy gauge, welded
wire-mesh, PVC coated to resist corrosion, around
base of machine to restrict unauthorized access.
F. Evaporator options:
1. Provide 1-1/2" cooler insulation in lieu of standard
3/4".
2. Provide DX Cooler with 300 PSIG water-side design
working pressure in lieu of standard 150 PSIG
3. Provide Raised Face Flanges for cooler nozzles:
a. 150 PSIG, welded anges (eld kit, mate
supplied).
b. 300 PSIG, welded anges (factory installed, no
mate supplied).
c. 150 PSIG, Victaulic™ Flanges (eld kit, no mate
supplied).
G. Flow Switch (Field-mounted): Vapor proof SPDT,
NEMA 4X switch ( ___ 150 PSIG or ___ 300 PSIG),
-20°F to 250°F.
H. High External Static Pressure Fans and Motors: Fac-
tory installed fans and motors for up to 0.4 inches
of water (100Pa) external static pressure at nominal
condenser air ow.
I. Microprocessor Membrane Keypad Graphics on in
lieu of Standard English:
1. French language.
2. Spanish language.
J. Thermal Storage: Leaving chilled liquid setpoint range
for charge cycle to 20°F (-6.7°C) (optional to as low
as 15°F (-9.4°C) minimum), automatic setpoint reset
of up to 40°F (22°C).
K. Low Temperature Process Brine: Leaving chilled
liquid setpoint range 20°F (-6.7°C) to 55°F (13°C);
optional to 15°F (-9.4°C).
L. Building Automation System (EMS) Reset Interface:
Chiller to accept 4 to 20mA, 0 to 10 VDC, or discrete
contact closure input to reset the leaving chilled liq-
uid temperature, or percent full load amps (current
limit).
M.Remote Control Panel (Field-mounted): Auxiliary
panel for remote user interface for functions normally
made at the unit control center.
N. Multi-Unit Sequence Control (Field-mounted): Sep-
arate Sequencing control center provided to permit
control of up to eight chillers in parallel based on
mixed liquid temperature.
O. Sound Reduction (Factory-mounted):
1. Low speed, reduced noise fans
2. Acoustic Silencer Kit
3. Compressor Sound Blankets
P. Vibration Isolation (Field-mounted):
1. Neoprene Isolators.
2. 1 Inch Deection Spring Isolators: Level adjustable,
spring and cage type isolators for mounting under
the unit base rails.
3. 2 Inch Deection Seismic Isolators: Level ad-
justable, restrained mounts in rugged welded
steel housing with vertical and horizontal limit
stops. Housings shall be designed to withstand a
minimum 1.0g accelerated force in all directions to
2".
