OPTIONS
Options are installed at the factory.
Accessories are shipped unmounted.
Extra Quiet Fan Operation (EQF)—using 855
RPM Fans and Scroll Compressors, provide the quietest
operating refrigeration equipment possible. There is a
slight capacity reduction caused by operating the unit
with 855 RPM fans, but the unit efficiency improvement
more than makes up for the loss in capacity.
Copper Fin Condenser (CUF)—Copper fin and
tube condenser.
Poly Fin Condenser (PFC)—The material is a
polyester paint baked onto the aluminum finstock prior
to final manufacture, rather than material applied to
the assembly after formation of the coils. The pre-
painted fin material has been tested for salt spray
corrosion resistance using ASTM B117 specification.
Oversized Cooler (CH2)—For 42°F (5.5°C) leaving
water temperature applications, 20% and higher glycol
applications will not require oversized coolers.
Oversized Cooler (CH3)—For 40°F (4.5°C) leaving
water temperature applications, 20% and higher glycol
applications will not require oversized coolers.
Convenience Outlet (CON)—dual 3-prong
ground fault receptacle powered from a dedicated
transformer and fused for 15 amps.
Hot Gas Bypass (HGB1)—for single or dual circuit
units to retain the unit on-line when the load is below
the minimum unit mechanical capability. This minimizes
compressor cycling and extends compressor life, on
extra low minimum load conditions (see Table 1 for
minimum load capability). HGB1 is supplied for the
First-On / Last-Off Stage Only, and for units without
compressor Lead-Lag control.
Hot Gas Bypass (HGB2)—for dual circuit units to
retain the unit on-line when the minimum load is below
the unit mechanical capability. This minimizes
compressor cycling and extends compressor life, on
extra low minimum load conditions (see Table 1 for
minimum load capability). HGB2 is supplied for the
First-On / Last-Off Stage Only, and for units with Auto
Compressor Lead-Lag Control.
Low Ambient Control (LAC) TO 0°F (-17.8°C)
Minimum Ambient—units use variable speed fans
in conjunction with standard fan cycling.
Extra Low Ambient Control (ELAC) TO -20°F
(-29°C) Minimum Ambient
—includes LAC and
EEV (Electronic Expansion Valve(s)) options and requires
the use of 50% glycol and roughly 50% load to ensure
extra low ambient starting, with a maximum of 5 MPH
(8 KPH) wind. Some limitations apply.
Low Ambient Lock-out (LALO)—uses an
ambient sensor and requires a lock-out set point
entered into the microcomputer controller.
Unit Mounted Disconnect Switch
(Non-fused) (UMD1)
—for 208 and 230 volt single power source units
ACDSB 015S thru ACDSB 100D - mounted in the control
box with mechanical interlock through the door.
Unit Mounted Disconnect Switch
(Non-Fused) (UMD3)
—for 460 and 575 volt single point power source units
—mounted in the control box with mechanical interlock
through the door, all models ACDSB 015S-100D.
Operating and Safety Lights (OSL)—lights
indicating control power to the unit and faults for high
discharge pressure, high motor temperature and alarm
status.
Gauges (GAG2)—includes suction and discharge
pressure for all unit models. The microcomputer
displays discharge and suction pressure so these
readings are redundant.
Louvers (Painted Galvanized Steel) (LUV)—
for complete unit enclosure for general mechanical
security and unit aesthetics.
Grill (Aluminum Painted) (GRL)—similar to the
louver option except manufactured of aluminum with
3/8" X 3 1/2" slots instead of louvers for security and
hail protection and unit aesthetics.
Fin Guard Top (FGT) (1" x 4" Coated Wire)—
protects the vertical condenser side coil only.
