Page 6: B. Pre-Installation
B. Pre-Installation ® Prior to installing the Hydronic Water Module and other EarthLinked space heating and cooling system above-ground components, you will need tools and equipment listed in Section 8 to properly install the system. Installation of the Hydronic Water Module must be done in accordance with this manual. -
Page 7: General System Layout
2. General System Layout ® Guidelines for the general layout of the Hydronic Water Module and other EarthLinked system components are shown in Figure 2. Figure 2. General Layout of System Components HWM-H-IOM (10/14) Page 7... -
Page 8: Application
3. Application Typical application of the Hydronic Water Module to radiant panel hydronic heating is illustrated in Figure 3. Figure 3. Typical Radiant Panel Hydronic Heating System IMPORTANT! This HWM series hydronic water module may be utilized with R-104A and R- 407C systems when the only function is to heat hydronic water. -
Page 9: The Primary Circuit
4. The Primary Circuit A. Plumbing The primary circuit in a typical HWM installation is shown in Figure 4. IMPORTANT! The hydronic water module (HWM) is to be mounted on a wall or fixed rigidly in place. The HWM is to be placed no more than 10 FEET AWAY FROM THE STORAGE WATER HEATER. - Page 10 Failure to isolate the heat exchanger will damage the heat exchanger causing system failure. Allowing highly chlorinated water to enter the heat exchanger will void ® the EarthLinked Limited Warranty. HWM-H-IOM (10/14) Page 10...

Page 13: C. Water Quality
C. Water Quality IMPORTANT! Always follow the propylene-glycol manufacturer’s instructions concerning the water quality specifications before filling the water circulating system. Water quality in hydronic systems is important to the life and efficiency of the system. Water of poor quality can cause a decrease in heat transfer ability and cause leaks. Ensuring proper quality water is a key step in the installation of the hydronic water module (HWM) and circulating water system. -
Page 14: D. Storage Water Heater Sizing And Connections
D. Storage Water Heater Sizing and Connections ® Storage water heaters are necessary with EarthLinked radiant panel hydronic heating systems, as typically illustrated in Figures 3 and 4. IMPORTANT A STORAGE WATER HEATER USED FOR HYDRONIC HEATING MUST BE EQUIPPED WITH SUPPLEMENTAL ELECTRIC HEATING WITH A RATING OF AT LEAST 20% OF THE DESIGN HEATING LOAD. -
