The components are as follows:
1.
Flowmeter
: Model ETI-A1-116000-1 hydronic water/antifreeze solution flowmeter is
available from ETI and is field calibrated for the specific antifreeze mixture. The kit
includes calibration equipment.
2.
Strainer:
Models ST-1836 (for 1.5 thru 3.0 ton systems) and ST-4272 (for 3.5 thru 6.0
ton systems) are 20 mesh, brass, inline strainers, available from ETI and necessary
to trap particles and maintain proper flow through the brazed plate heat exchanger
channels.
3.
Temperature Controller:
Model HHK-1872 is a hydronic heating controller. This
controller can be mounted remotely and comes with a capillary tube 6 feet long,
thermal bulb, thermal paste and the NPT thermal well insert and is available from ETI.
4.
Storage Water Heater:
The GSTE Series storage water heaters are available from
ETI in 60, 80 and 119 US Gallon capacities, and are designed for use with the
EarthLinked
®
geothermal systems. They are equipped with a 4.5 kW supplemental
heater which satisfies the ETI requirement for a minimum of 20% supplemental heat.
5.
Other Plumbing Components and Parts:
Gate valves, unions, copper pipe, pipe
insulation, etc. meeting USA industry and local code standards are commercially
available through plumbing supply outlets.
All plumbing installations are to be in accordance with the applicable local and
national codes.
To protect the brazed plate heat exchanger
from damage during cooling operation
when the heat exchanger is producing chilled water, a factory installed thermal switch
at the outlet of the heat exchanger will turn the compressor OFF when the chilled
water temperature drops to 38°F.
WARNING!
The heat exchanger must be isolated from the water system when the
system undergoes a “superchlorination” or “shock chlorination”
flushing process. Closing the isolation valves as shown in Figure 4
prior to initiating the system flushing process isolates the heat
exchanger. The water entering the heat exchanger after the system
flushing must not exceed a chlorine level consistent with the local
municipal water purification standards. 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.
