Disclaimer
Proper installation of the EarthLinked®Heating and Cooling System is essential to its reliable
performance. All EarthLinked®systems must be installed by an authorized, trained technician who
has successfully completed the training class and passed the final examination. Installation must
be made in accordance with the instructions set forth in this manual and the current EarthLinked
Heating and Cooling Installation, Operation and Maintenance Manual. Failure to provide
installation 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.

1. All series Compressor Units: CC, SC, SD, SCW, SW, HC, HCW, HW, HWW
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
2. All series Earth Loops: V1, D1, T1, V1.5, D1.5, V2, D2, D3, H1, H5
3. ACMs are for CC, SC, SD, SCW and SW compressor units only.
Note: Desuperheater and all EarthLinked®thermostats can be utilized throughout capacity range.

Guidelines for the general layout of the system components are shown in Figure 2. Before placing
the compressor unit (outside or indoors), review the guidelines in Figure 2.

Figure 2. General System Layout
Placement
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.
•Where the total length of refrigerant line sets (from manifolds to compressor and from
compressor to air handler) do not exceed 125 feet, as shown in Figure 2.
•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 2.
•For SCW, HCW and HWW compressor units providing radiant panel hydronic hot water, where
the hydronic primary circuit is adequately protected from freezing by controlling the surrounding
lowest air temperature to 40oF minimum and/or providing an industry approved anti-freeze and
water mixture for the surrounding lowest air temperature.

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.
