Introduction
LS air-cooled water chillers are complete, self-contained automatic refrigerating units that include the latest in
engineering components arranged to provide a compact and efficient unit. Each unit is completely assembled;
factory wired, evacuated, charged, tested and comes complete and ready for installation. Each unit consists of
multiple air-cooled condensers with integral sub-cooler sections, one or more accessible semi-hermetic double-
screw compressors, star-delta starters, flooded type shell-and-tube evaporator, and complete refrigerant piping.
Liquid line components included are manual liquid line shutoff valves, charging valves, filter-driers, liquid line
solenoid valves, sight glass/moisture indicators, and electronic expansion valves.
Inspection
When the equipment is received, all items should be carefully checked against the bill of lading to ensure a
complete shipment. All units should be carefully inspected for damage upon arrival. The unit’s serial plate should
be checked before unloading the unit to be sure that it agrees with the power supply available. Physical damage to
unit after acceptance is not the responsibility of LS Company.
