Introduction; Nomenclature - Emerson Copeland Scroll XFAL Series Installation And Reference Manual

1. Introduction

Copeland Scroll Outdoor Refrigeration Units provide
™
the many benefits of scroll compressor technology,
coupled with advanced diagnostic controls, to ensure
reliable performance and operation in foodservice
applications.
Electronics are used extensively in its protection and
diagnostic features. These features are controlled by
an electronic integrated control module. The Dixell
XCM25D control module with CoreSense
provides control functions related to temperature and
pressure control, defrost, and compressor protection.
Units are available in 1.5 to 6 HP for coolers and 2 to
6 HP for freezers. All units are 208/230 volts and are
available in single or three phase. All -081 bill of material
units come factory equipped with a heated and insulated
receiver, service valves, pressure controls, defrost
control, filter drier, moisture indicator, crankcase heater,
variable speed condenser fan, CoreSense Protection,
CoreSense Diagnostics, and two-way communications
standard.
Low temperature XFAL units (-40°F to 0°F saturated
suction) also feature an accumulator and oil separator.
Discharge line temperature control is provided by
enhanced vapor injection (EVI).
Medium temperature XFAM units (0°F to +45°F
saturated suction) include all the standard features.

Discharge line temperature control is accomplished by
suction line liquid injection.
Extended medium temp XFAP units (-25F to +45F
saturated suction) feature an accumulator. Discharge
line temperature control is accomplished by suction line
liquid injection.
The Dixell XCM25D Electronic Control Module with
CoreSense technology (control module) on Copeland
™
condensing units provides many benefits to the
contractor and end-user. It is designed specifically for
demanding refrigeration applications to ensure simple
installation and precision operation. While the control
module replaces existing adjustable low pressure
controls, fan cycle switches and other relays, it also
has additional features. These features include bump
start, data storage, communication, and short cycling
protection.
The control module is preprogrammed with the proper
settings, resulting in little to no setup time. The unit
comes with instructions showing how to adjust the low
pressure cut-in and cut out. See the label on the inside
of the enclosure for more information.
Condensing unit operating range: -40°F to +120°F
