Justin, I just called Summit to change my order from the Milodon unit to the Flow Kooler 1700. I made the previous order and then read your post. Then I spent some time reviewing the FK information.
Thank you.
Note: FlowKooler confirmed (per email) that a HF thermostat should be used for maximum flow rate.
