sense and display suction temperature.
E. Control Power Transformer: Converts unit power
voltage to 120-1-60 (500 VA capacity). Factory
mounting includes primary- and secondary-wiring
between the transformer and the control panel.
F. Motor Current Module: Capable of monitoring com-
pressor motor current. Provides extra protection
against compressor reverse rotation, phase-loss
and phase imbalance. Options consists of one
module per electrical system. (Factory mounted)
G. Power Factor Correction Capacitors: Provided to
correct unit compressor factors to a 0.90-0.95.
H. Condenser Coil Environmental Protection:
1. Pre-Coated: Epoxy coated aluminum fin stock
to guard from corrosive agents and insulate
against galvanic potential. For mild seashore
or industrial locations.
2. Copper Fin: Provide copper fins in lieu of
aluminum.
3. Post-Coated Dipped: Dipped-cured coating on
condenser coils for seashore and other corro-
sive applications (with the exception of strong
alkalis, oxidizers, and wet bromine, chlorine
and fluorine in concentrations greater than
100ppm).
I. Protective Condensing Unit Panels (Factory or Field
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, coated to resist corrosion, to protect
condenser coils from incidental damage and
restrict unauthorized access to internal com-
ponents.
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, coated to resist corrosion,
around base of machine to restrict unauthorized
access.
J. Service Isolation valves: Service suction and dis-
charge (ball type) isolation valves are added to unit
per system. This option also includes a system high
pressure relief valve in compliance with ASHRAE
15. (Factory-mounted.)
K. Hot Gas By-Pass: Permits continuous, stable opera-
tion at capacities below the minimum step of unload-
ing to as low as 5% capacity (depending on both
the unit & operating conditions) by introducing an
artificial load. Hot gas by-pass is available installed
on one or both refrigerant circuit(s).
L. Microprocessor Membrane Keypad Graphics on in
lieu of Standard English:
1. French language.
2. German language.
3. Spanish language.
4. Italian language.
M. Chicago Code Relief Valves to meet Chicago Code
requirements.
N. Building Automation System (EMS) Reset Interface:
Condensing Unit to accept 4 to 20mA, 0 to 10 VDC,
or discrete contact closure input to reset the dis-
charge air temperature.
O. Remote Control Panel (Field Mounted): Auxiliary
panel for remote user interface for functions nor-
mally made at the unit control center. Available on
YCUL0016-0090 models.
P. OptiView Remote Control Panel (Field-mounted)
Graphical interface panel to remotely control and
monitor up to 8 units
Q. Sound Reduction (Factory Mounted):
1. Low speed, reduced noise fans
2. Compressor Acoustic Sound Blankets
R. Vibration Isolation (Field Mounted):
1. Neoprene Pad Isolators.
2. 1 Inch Deflection Spring Isolators: Level adjust-
able, spring and cage type isolators for mount-
ing under the unit base rails.
3. 2 Inch Deflection Seismic Isolators: Level
adjustable, restrained mounts in rugged welded
steel housing with vertical and
horizontal limit stops. Housings shall be
designed to withstand a minimum 1.0g accel-
