## Description

Instructions for use-Fill the water tank until you see the fill line gauge show that the water level is near the max fill line.-Plug in the Mattress Cooler and power on. The default setting will be the coldest so to make the mattress pad less cool you will need to adjust the fan and pump settings.F1 is High Fan, F4 is the lowest fan setting.D1 is continuous pump, D2 and D3 have timed pumping with D2 being the shortest pump cycle. D4 is pump only and no fan, the least cold setting. -To improve cooling, you need to clean the filter and unit regularly, usually about once every 2 weeks. Also you can add up to 1/8 tsp (not much at all) of laundry bleach to the water to reduce the risk of growth in the system.NOTE: If the current setting doesn't achieve the cooling effect you need, you can try switching from room temperature water to ice water.-Press "on". If you get an E1 error, turn off the cooler, add water, then power on.-The main unit needs to be placed parallel or above the mattress to avoid backflow leaks.-If leakage occurs at the bottom of the tank, the drain plug may be loose or missing, just replace it.Purchase PrecautionsAs the host is non-enclosed, the fan rotation process will have some small noise, generally does not affect the sleep, but sensitive to the sound of the person to buy with caution.

## Questions & Answers

**Q: Is a Replacement pad available yet!**
A: Dear Walktts, we have specialized in manufacturing alternative mattress pads, but the US Customs requires certification that the cotton used to manufacture these mattress pads is not from Xinjiang, otherwise it cannot be imported, but we do not have the required documents to prove it. So maybe next year, our replacement mattress pad can be sold in the United States.

**Q: Reviewers said have to add water every night — so where does the water go?**
A: You put water in the top of the unit. It evaporates as it is being used. The warmer it is in the house (and outside), the more water it uses to cool. We are having 90+ degree days here , and I am having to add more water each day. I don't mind one bit though, because it keeps me cool

**Q: Can this cooling unit be set on the floor like under the nightstand?**
A: there are specific instructions for setting the unit below the mattress.  I did not use it this way.

**Q: Will you be selling a small pad to use on just a pillow?  I don't want a pad to cover the whole bed.  Just need one for a pillow.**
A: It’s probably about 2 1/2 ft from to bottom and a slight bit wider than a king size bed. All I’m aware of.
