Installers have our first unit up and running! :-) They aren't real sure about the setup measurements. We seem to have at least 21-25 degree drop in air temp (supply/return). Measuring Initial EWT/LWT its around 64 EWT/ 73LWT..... In the P/T connector on the entering/leaving water connections what water pressure should we see? It barely moves the meter? They are trying to see a pressure drop, and not sure what is happening. The pumps are working/running, and the interior temp is rapidly cooling...... What is the nominal pressure that the supply/return water (closed loop 5-ton) should be? The driller said he can come back tomorrow to add pressure? Edit: I think we found that we should add water to the loop to increase pressure up around 40psi operating. thoughts?
