## Questions & Answers

A: This product does not come with a injector. Service hvac handset is needed. To inject product into system.

**Q: can i use this product for 3 Tons unit?**
A: Yes you can this package is good for units from 2Tons up to a 10Ton unit.

**Q: Does this have dye in it?**
A: The manufacturer states that "And now the industry’s leading refrigeration sealant has been combined with UV leak detection dye to give you EasySeal Direct Inject-UV. This product is designed to seal leaks and also show where larger leaks are with the use of the UV Leak Detection Kit (4050-15)."  I used it over a year ago and do not remember whether or not it had a visible dye in it.  Sure did the job and I can recommend it.  I used it on a Water Source heat pump and the leak had to be in one of the two water to refrigerant heat exchangers.  I still do not know which one.

**Q: Can this product be used on a refrigerator? if so what tons do I purchase. Can too much be a bad ting?**
A: Hi! The first thing I would do is call the refrigerator manufacturer and discuss this with it's Tech department to see what they say and if they have any recommendations (besides buying a new 'fridge!).
