Heater Install

[Paul W]

Hi,
I am currently installing a HeaterCraft 4 port heater in my 2017 San230 Costal with the H5 engine. It has partial closed cooling for the engine. There are some taps, sends and returns. off the engine for a heater as listed on the attached PDF part numbers 20, with a temp hose #23 connecting. The issue that I am having is that I can not find any information on which one is the send. The send is going to an inline pump and then to the heater. The return will be coming from the heater and back to either one #20 ball valves.
Is there any way to determine which are the send and returns? The PDF is from Page #24 of the PCM parts manual. Thanks for your help, Paul

Page 57 of the H5/H6 manual shows the inlet and outlet, but I don't see the ball valves in the black-and-white photo they use:

Awesome. Where did you put the heater assembly?

I installed the heater in the starboard locker compartment up against the back seat. There is plenty of room and easy access to everything. I kept it high so its out of the way of the wakeboard bags. It looked like a challenge to install under the helm. Just have to wire it up now and it ready for a test, although it was 22 degrees this morning in Northern IL.
