The SpaCap is the most revolutionary spa cover and will forever change your ideas about what a hot tub cover should be. The only cover of its kind, the SpaCap's patented design makes using your spa as easy as getting into bed. Using no rigid foam panels, that will always end up broken or saturated, the air chambers start insulating right at the water surface so you don't lose heat or chemicals through evaporation and condensation that would otherwise be going on under a traditional foam filled cover. This remarkable cover lets you enjoy using your spa without throwing out your back.

1. Make sure hot tub is filled to proper amount. The Proper amount is whatever the spa manufacturer suggests the spa water to be for proper operation of the spa. The SpaCap rests right on the water surface so make sure your spa has water in it.
2. Distinguish the top from the bottom and observe the location of the valves. The top is the side of the Spacap that shows when it is on the spa. The bottom is the side with the valves on it. When the SpaCap is on the spa, the bottom will rest on the water.
3. Place the SpaCap on spa, laying it on water surface. Top side up. You are meant to fold the cover back to expose the valves to fill the SpaCap.
Note: Valves are meant to be on underside when cover is on hot tub.
4. Inflation. Open the flap of the valve you intend to put air in. Prop open the inner check valve with a plastic funnel. The funnel will also divert the air into the cover. In order to put air into the SpaCap you need something that moves a volume of air. For example a shop vac that has an exhaust port you can hook the hose into or a leaf blower. An air compressor would work but it will take longer since it is designed to move air under pressure. The SpaCap is not designed to be under pressure.
Inflate the "Top" valve first until there is about eight inches of air. Inflate the bottom unmarked chamber to desired level. We recommend using a shop vac to inflate your SpaCap.
5. Close valves and center the cover on the spa so that it evenly covers the entire hot tub.
6. Place fasteners as needed. You may choose not to install the fasteners, but they do help the Spa Cap keep its shape, insulate better and keep the moisture running off. The fasteners should be equally spaced and should go below the acrylic of the spa. If your spa has a wood lip that protrudes further then the acrylic the fasteners should go about three inches below the wood lip. If as you are installing the fasteners the cover becomes difficult to fasten on the last side, you have too much air in the cover. There should still be a little give in the cover when fastened and the corners should not be lifting.
7. Congratulations on the purchase of your new SpaCap cover! Yes, it is different, but it works better than any other cover on the market.
