General information
The multiple-compressor WCVS units
consist of compressors, water-cooled
condensers, an evaporator coil, and FC
fan. Each unit is shipped with refrigerant
and oil charge with complete refrigerant
piping. Each refrigerant circuit includes
a brazed filter-drier, condenser pressure
relief valve, sightglass, high and low
pressure access ports, thermal
expansion valve with external
equalizer, lock-out safety and thermal
overloads for each compressor, time
delay safety and high-low pressure
cut-out switches.
The evaporator fan is of double-width
double inlet forward curved fan.
Rigging
Before preparing the unit or
component for lifting, estimate the
approximate centre of gravity for lifting
safety. Due to the placement of internal
components, the unit weights may be
unevenly distributed. Unit weights are
provided in the general specification.
WARNING: To prevent injury or
death and unit damage, observe
handling cautions and procedures
given in Figure 1 when lifting the unit.
Always test-lift the unit to determine
actual centre of gravity.
Special Note on Refrigeration
Emissions
World environmental scientists have
concluded, based on the best
currently available evidence, that
ozone in our upper atmosphere is
being reduced due to release of CFC
fully halogenated compounds.
Trane-Ingersoll Rand urges all
HVAC servicers working on Trane
equipment, or any manufacturer
’ s
products, make every effort to
eliminate , if possible, or vigorously
reduce the emission of CFC , HCFC ,
and HFC refrigerants to the
atmosphere resulting from
installation, operation, routine
maintenance, or major service on
this equipment. Always act in a
responsible manner to conserve
refrigerants for continued use even
when acceptable alternatives are
available.
