Pre-Installation IMPORTANT! This EarthLinked® Hybrid Cooling Module (HCM) is for use with EarthLinked® space heating and cooling systems that provide cooling. The HCM is a required component of the EarthLinked® systems where indicated in the EarthLinked® Performance Tables for R-410A systems. - Page 5 WARNING! Inhalation of high concentrations of refrigerant gas vapor is harmful and may cause heart irregularities, unconsciousness or death. Vapor reduces oxygen available for breathing and is heavier than air. Decomposition products are hazardous. Liquid contact can cause frostbite. Avoid contact of liquid with eyes and prolonged skin exposure.

EarthLinked system. The Hybrid Cooling Module is located outdoors and will be connected to the refrigerant line set (vapor tube) outside the building. ® Figure 2. Hybrid Cooling Module Placement in EarthLinked System NOTES: All refrigerant and water lines between these above ground components must be insulated with at least 1/2”... - Page 7 Location Requirements for the Hybrid Cooling Module: 1. Within 20 feet of the earth loop line set. Minimize refrigerant line lengths. 2. No more than 20 feet higher than the earth loop manifolds. 3. With proper clearances around the unit: ...

Page 8: Installation - Refrigerant Connections
Installation – Refrigerant Connections The Hybrid Cooling Module has two refrigerant connections on the service side of the unit as shown in Figure 1. Each connection is 7/8”. Each connection is identified with a label saying “Compressor” or “Earth loops”. Check Figure 1 and the table on page 4 to determine coupling sizes to match the line set vapor tube size. - Page 9 A top view of typical Hybrid Cooling Module and line set vapor line connections are illustrated in Figure 4. For new installations of an EarthLinked system with an HCM, an alternate method to the one shown in Figure 4 is to run a single piece vapor line from the compressor unit to the HCM and another single piece vapor line from the HCM to the vapor manifold of the earth loop system.
