HSF-3 stopped working? How do you link the FAV & SYS to test system?

Do you know at what temp the Water/Meth would freeze at if at all, I'm running a 50/50 mix?

I though that the PRK peg was used as a spare, But the instructions on the HSF-3 V11 Do not make it clear, that you use the PRK peg to test the system.
So i was reluctant to use it incase things then went badly wrong.

I will do the test this weekend due to my work, And post the result.

Many thanks.

What is the serial number of the system?

If you are doing a manual system activation, the "PRK" jumper is the obvious one to use. If you unplug the FAV, nothing can flow pass it. It is unlikely the fluid was frozen if you have a true M50/W50 mix.

The instruction is very clear, you are the first person one that doesn't understand it.

I do need to know the serial number and your date and place of purchase.
