Disclaimer
Proper installation and servicing of the EarthLinked®Heating and Cooling System is essential to its
reliable performance. All EarthLinked®systems must be installed and serviced by an authorized,
trained technician who has successfully completed the training class and passed the final
examination. Installation and service must be made in accordance with the instructions set forth in
this manual and the current EarthLinked Heating and Cooling Systems Installation, Operation and
Maintenance Manual. Failure to provide installation and service by an authorized, trained installer
in a manner consistent with the subject manuals will void and nullify the limited warranty coverage
for the system.
READ THE CURRENT EarthLinked Heating and Cooling Installation, Operation and
Maintenance Manual FOR COMPLETE INSTALLATION DETAILS.
EarthlinkedTechnologies shall not be liable for any defect, unsatisfactory performance, damage or
loss, whether direct or consequential, relative to the design, manufacture, construction, application
or installation of the field specified components.

Contained in each compressor package:
•compressor unit
•four L-shaped hold down brackets
•service valves-liquid and vapor
•adapters for service valves and earth loop line set
•product literature

Guidelines for the general layout of the system components are shown in Figures 2a and 2b.
Before placing the compressor unit (outside or indoors), review the guidelines in Figures 2a and
2b, and the information regarding the Auxiliary Cooling Module and Heating Performance
Enhancement Control following Figure 2b.

Placement and Mechanical Information
EarthLinked®compressor units may be located outside or inside the building, following these
guidelines.
OUTSIDE
Locate compressor unit:
•On a standard HVAC condensing unit pad, resting on firm, level, settled ground.
•Same as for INSIDE placement. See below.
INSIDE
Locate compressor unit:
•On a solid, level hard surface. If compressor unit is to be fastened, see Figure 3 for bracket
installation.
•Where compressor unit sound and vibration will not disturb human activities. Compressor unit
may be located in garage, basement, crawl space or utility room. Avoid placing compressor unit
in kitchen, bedroom, family/living/dining room areas.
•In a condensate pan.
•On vibration pads.
•Attic installations, where necessary, must include a drip pan, anti-vibration pads and are to be
suspended from the rafters with suspension isolators.
•For SD compressor units (which have potable domestic water connections) where the
surrounding air temperature remains above 40°F.
•Where suggested clearance is 3 feet on both sides, top and front, for access. However, local
codes and applicable regulations take precedence. Clearance from back panel to wall and
minimum side clearance should be at least one foot. See Figure 4 for details.
SCW-410-QS (05/12) Page 6
•Where the total length of refrigerant line sets (from manifolds to compressor unit and from
compressor unit to air handler) do not exceed 125 feet, as shown in Figure 2a.
•Where the compressor unit is no more than 20 feet higher than the earth loop manifolds.
Compressor unit may be located lower than the earth loop manifolds. See Figure 2a.
•For SCW compressor units providing radiant panel hydronic hot water or chilled water, where
the hydronic primary circuit is adequately protected from freezing by providing adequate site-
specific antifreeze protection for the water circulating system.

Compressor units are shipped from the factory with a low pressure nitrogen holding charge.
Carefully relieve the holding charge when the compressor unit is being prepared to connect
refrigerant system piping.
The compressor unit package contains a service valve kit and an adapter kit. The two service
valves are to be installed on the earth loop vapor and liquid connections of the compressor
unit, using the adapters to right-size to the proper earth loop line set.
Installation of the service valves will provide isolation of the earth loop system from the compressor
unit and provide easy access to the refrigerant system.
The service valve configuration provided is illustrated in Figure 4a. The ball valve stem is
accessed by removing the cap. The service port is equipped with a Schrader valve insert.
Figure 4a. Service Valve Orientation
Complete service valve installation instructions are contained in the Service Valve Kit Installation
Manual, included with the service valves.
