“The new heat pump water heater was delivering only slightly warm water. Couldn't figure it out. Adjusted the water temp on the main control without much result. The mixing valve on the water heater is challenging—what looks like a knob to be turned is actually a key you have to pull off, reverse, and use to turn the valve to adjust the water mix. Who knew? Might want to leave that info with customer. The guys showed up the next morning and i had a lesson in how to use the thing. Working well now.”
