Guide Specifications
5.9
CABINET
The condenser cabinet shall be divided into fan and coil sections by full width baffles per
corresponding DX circuits. Internal structural support members, including coil support frame, shall
be painted or galvanized steel for strength and corrosion resistance. Panel doors are provided on
the outside of each coil/fan section to provide for coil cleaning. An electrical panel shall be
contained inside a factory mounted, NEMA 3R weatherproof electrical enclosure. Galvanized steel
base is available and required to support the condenser mounting, rigging and airflow.
5.10 LIEBERT DSE™ RECEIVER
Liebert DSE Receiver shall be painted, un-insulated receiver with integral fusible plug, formed
copper pipe for ease of connecting condenser liquid line to receiver and mounting bracket. These
receivers are factory installed and piped to the Liebert MCV Skid assembly
5.11 LIEBERT ECONOPHASE
The Liebert EconoPhase has two variable speed refrigerant pumps controlled by individual VFDs,
factory wired electrical panel, factory piped and tested refrigerant piping all housed within a bright
aluminum NEMA 3R enclosure. The Liebert EconoPhase is mounted, wired, and piped into the
Liebert MCV Condenser Skid to provide significant jobsite installation savings. The Liebert
EconoPhase refrigerant pumps are individually activated and speed controlled during cooler
outdoor ambient, coordinated with Liebert DSE compressors idled and refrigerant bypassed around
them. Cool temperatures, such as mild weather and at night, partial economization and power
savings is provided with one pump activated and one compressor idled. Colder temperatures, such
as winter weather, allow both Liebert DSE compressors to be idled and EconoPhase pumps to be
controlled independently to provide full economization
5.12 CONDENSER HOUSING
The condenser housing is constructed of galvanized steel and divided into individual fan sections
by full width baffles. Internal structural support members, including coil support frame, are
galvanized steel for strength and corrosion resistance. Panel doors are provided on the outside of
each coil/fan section to provide for coil cleaning. Galvanized steel base is available and required to
support the condenser mounting, rigging and airflow.
Condenser shall be shipped pre-installed on a base structure that includes the EconoPhase pumped
refrigerant economizer, refrigerant receivers and all associated piping.
