Plumbing
A typical primary hydronic plumbing circuit for an SD(H) system is illustrated in Figure 11.
Figure 11. Typical SD(H) Primary Hydronic Circuit Plumbing
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 come with a capillary tube 6 feet long, thermal bulb, thermal
paste and the NPT thermal well insert and are available from ETI.
