## Questions & Answers

**Q: Can i use at 240 ac cutoff service panel for heatpump ?**
A: Yes.  I replaced my SyCom surge protectors with this unit.

**Q: Can i used this in line to neutral 220v i used it in philippines**
A: So in the questions part of the sellers page it is suggested that both the red and black can be connected together with the 220 line and  provide 220v protection, to be sure I would suggest contacting midnite solar.

**Q: How to install this on a single phase 240v 60hz system here in asia, there is no l1 and l2, just line / n / ground. leave out the red or black?**
A: Red is 120v black is 120v = 240 vac
You will have to put them together to acheive 240vac.  Otherwise you will only get 120volts ac if you only use one.

**Q: If this item fails to protect my components will the company pay for my losses?**
A: No idea if company will pay .but I can confirm the product is strong and works efficiently
