## Questions & Answers

**Q: Is this a 120v or 240. Seems like the description is all messed up? To hard wire is it 1 hot, 1 neutral, & 1 ground?**
A: 120v…yes

**Q: The med setting on my atmor inline 800  240 volt 13kw don't engage**
A: not sure why the middle setting won't work when the other settings will work, probably has something to do with the amps going into the system, it would set it off as the amp are either too low or too high..

**Q: Can this unit be installed as a booster for a faucet far away from the current hot water tank? Will it shut off when the supply water is hot?**
A: No, This unit turns on when a faucet is opened, pressure drop, not water temp. You need a small point of use heater for your remote sink.

**Q: I installed this heater on Friday, today is Wednesday and this morning it is not working. how do i get this replaced. It has a dedicated 30amp breaker**
A: Return it and buy a different brand.  I bought it but never installed it just returned for one with metal internal parts because my plumber saw it and said it was too cheaply made it won’t last.  I was lucky.

### ⭐ Defective and lack of support!

DO NOT BUY!

### ⭐ will not heat water past luke warm. No help from Atmor. Very poor product.
*by D***K on September 6, 2022*

Will not heat water past Luke warm and that's even at low water flow. If you actually read the owners manual it states that it will not heat water if the supply water is at or below 50 degrees F. My water supply is not well water and its 80+ degrees outside.
