Yes. Mix it with distilled water. As the label suggests. I would never run straight coolant. I've always mixed at 50/50 with zero issues for 40+ years.

I've always been told stay away from tap water even just for flushing. It will leave deposits. Buy some distilled water at the grocery store and use that to mix. Buy a couple gallons extra if you flush first.
Those are some crazy instructions on the bottle. That was probably a poor translation from Japanese.
Looks like if you go 50/50 that should bring your antifreeze protection to -36° F. I haven't used the exact coolant you have but the brand specific coolant I have used was mixed 50/50 distilled water/coolant and my tester tells me about -25° F for the last couple years when I have tested it.
What I would do is take a graduated cylinder and measure 10 ml of your Ecstar coolant with 10 ml of distilled water. Test it. What antifreeze protection does your tester tell you? It should be -36 C according to the table on the bottle. Then add 10 additional ml of distilled water and test the sample again. Does the test indicate -15 C? If it does, I'd conclude you should mix the Ecstar with distilled water according to the table. After you run it in the engine, I would definitely NOT add just distilled water as the directions seem to say. That will reduce the antifreeze protection you had carefully achieved by premixing. Trying to get the antifreeze protection correct after the coolant is in the engine is a nightmare. Drain, add water, test, drain, add coolant.....test.... It takes forever.
If you want to avoid fussing with adjusting the antifreeze protection, I suggest not flushing at all. Flushing will leave at least 8 oz of pure distilled water trapped in the motor and that is enough to significantly effect the antifreeze protection. Then you need to drain and add and test until you get it right. What I did the last time was flush with distilled water and then flush one time with 50/50 coolant. Then I drained the flush coolant and put in a fresh batch of 50/50 coolant. That got it just about to the right antifreeze protection level. It still was a tad bit week. If you do what I did flushing with antifreeze and then emptying it, you could just test what was emptied, adjust as needed and pour it back in. I hate to pour fluids back in after they have drained because I fear there may be some debris that will get poured in the engine.
BTW, I think it's best to test antifreeze when the coolant is cold. Warm antifreeze might not test the same as cold. That's how it seemed the last time I did this job.
Here you go if you want to do the whole job. IDK, maybe you're just adding a bit of coolant to your radiator.
