ensures that refrigerant is delivered to the indoor unit coils for optimal system perfor-
mance and capacity.

-based application assists the design
engineer with specifying and sizing outdoor and indoor units (by calculating component
capacity based on design conditions), laying out the refrigeration distribution pipe
system, checking piping limitations, calculating refrigerant charge, and generating
equipment schedules and piping diagrams in (.dxf) format for use on CAD building design drawings.*

To ensure that the refrigerant piping design meets LG’s quality standards, a LATS refrigerant piping design must be provided with

created and provided to LG prior to system commissioning to ensure the proper pipe size has not changed.
Adjusting LATS Multi V S Output for Altitude
When a system is installed at elevations significantly above sea level, consider the impact air density has on the capacity of the indoor and
air-source units. LATS does not de-rate indoor unit capacity for high altitude applications. Be sure to apply locally accepted correction factors
when calculating actual indoor unit capacities at that altitude.
