Pre-Installation
EarthLinked
®
compressor units that provide space cooling shall be equipped with an
EarthLinked
®
Auxiliary Cooling Module when BOTH of the following circumstances occur:
•
Ambient outdoor temperatures have exceeded the outdoor summer design
temperature conditions for at least 7 hours of continuous system run time, coupled
with the following conditions.
•
Low thermal conductivity soils that do not effectively absorb and dissipate heat.
Examples of such soils are light dry soil, dry sand, peat and organic soils, dry clay
soils and hardpan.
This Auxiliary Cooling Module is sold as a system component and must be properly matched with
the compressor unit to provide the anticipated performance and safe operation of the system. The
table below lists the properly matched EarthLinked
®
Auxiliary Cooling Module models with
EarthLinked
®
compressor unit models.
Application of the Auxiliary Cooling Module (ACM) to EarthLinked
®
systems will require the
use of two (2) field supplied Type ACR copper couplings to match the ACM with the line set
vapor tube size.
See the table below to determine the required coupling sizes.
