1. General Description of Applications
The GSTE-60, GSTE-80 and GSTE-119 Storage Water Heaters are applied to the following
EarthLinked®systems. Installation instructions for each of these applications follow.
•Earthlinked®Commercial Water Heating Applications providing heated potable
water from the compressor unit and delivered to a storage water heater, where reserve
electric heating is required if the compressor unit is out of service. The electric heat
would be activated manually at the breaker if the compressor unit is taken off line. This
application is detailed in Section 2.
•EarthLinked®Domestic Water Heating Applications utilizing the Domestic Water
Module (DWM) providing heated potable water from the DWM and delivered to a
storage water heater, where reserve electric heating element is required if the
compressor unit is out of service. The electric heat would be activated manually at the
breaker if the compressor unit is taken off line.This application is detailed in Section 3.
•EarthLinked®Desuperheater Water Heating Applications utilizing the SD
Compressor Unit (equipped with a desuperheater) or the Model DSH-1872
Desuperheater Kit applied to an SC or SW compressor unit providing heated
potable water to supplement the standard electric storage water heater. In this
application, the desuperheater operates to heat water when the EarthLinked®Heating
and Cooling System is operating in cooling mode. The desuperheater functions to
supplement, but not replace, the water being heated by the standard storage water
heater. This application is detailed in Section 4.
•EarthLinked®Hydronic Heating and Chilled water Cooling Applications utilizing
the Hydronic Water Module (HWM) providing heated hydronic water solution from
the HWM and delivered to the storage water heater (the primary circuit) where an
electric heating element supplements the heating of the hydronic water solution as a
function of outdoor temperature, controlled by an outdoor thermostat. This application is
detailed in Section 5.
The EarthLinked®Model GSTE Storage Water Heater description appears in Figure 1. In
addition to the storage water heater, temperature control Model HHK-1872 is required for
commercial water heating, domestic water heating and radiant panel hydronic heating
applications; and the temperature control Model CWK-1872 is required for chilled water cooling
applications.

2. EarthLinked®Commercial Water Heating Applications
Figure 2a illustrates a typical installation of a GSTE storage water heater with a commercial
water heating compressor unit. Location of the tank from the compressor unit is to be no more
than 10 ft. apart. Water piping and connections between the compressor unit and tank are all
1-1/2” Type L copper. Hot water supply to the system is out the top of the tank as shown.
Details for the ports and connections on top of the tank are shown in Figure 2b. The electrical
field wiring for the HHK-1872 temperature controller and the storage water heater electric
element and thermostat are illustrated in Figure 2c.

3. EarthLinked®Domestic Water Heating (DWM) Applications
Figure 3a illustrates the installation of GSTE storage water heater with a Domestic Water
Module for a residential heating application. Location of the GSTE storage water heater from
the DWM is to be no more than 10 ft. apart. Water piping and connections between the
compressor unit and tank are all 1-1/2” Type L copper for the models DWM-4248 and DWM-
6072. Piping and connections are 1” Type L copper for model DWM-1836. Detail for the ports
and connections on top of the storage water heater are shown in Figure 3b. The electrical field
wiring for the electric heater element and thermostat are illustrated in Figure 3c.

4. EarthLinked®Desuperheater Water Heating Applications
Figure 4a illustrates the installation of a GSTE storage water heater with a Desuperheater
supplementing the hot water heating function. Although the desuperheater in Figure 4a is
shown as a separate unit, (as Desuperheater Kit Model DSH-1872 applied to SC and SW
compressor units) the installation instructions apply to the SD compressor unit also.(The SD
incorporates the desuperheater within the compressor unit cabinet). Location of the water
heater from the Desuperheater (or the SD compressor unit) is to be no more than 10 ft. apart.
Water piping connections between the Desuperheater (or SD compressor unit) and the water
heater are ½” Type L copper. Details for the ports and connections on top of the water heater
are shown in Figure 4b. The electrical field wiring for the electric heating element and
thermostat are illustrated in Figure 4c.

5. EarthLinked®Hydronic Heating and Chilled Water Cooling (HWM)
Applications
Hydronic Heating Only:
Figure 5a illustrates the installation of a GSTE storage water heater with the Hydronic Water
Module (HWM) providing heated water (only) to a hydronic system. Location of the storage
water heater from the HWM is to be no more than 10 ft. apart. Water piping and fittings
between the HWM and the storage water heater are to be 1” Type L copper for model HWM-
1836, and 1-1/2” Type L copper for models HWM-4248 and HWM-6072. Detail for the ports
and connections on top of the tank are illustrated in Figure 5b. The electrical field wiring for the
HHK-1872 temperature controller and the electric heater element and thermostat are illustrated
in Figure 5c.
