For first-time users, I don't know how to fill the spa blanket. Can the spa blanket be used without water injection? Let's take a look at it through the article.

Water injection steps of spa blanket:

1. First, add enough water into the water injector of the spa blanket, then screw on the top cover of the spa blanket and remove the cover of the water injection hole.

2. Then pull out the water injection pipe of the spa blanket and unscrew it, so that the water injection port of the water injector is connected with the main water pipe.

3. After completion, it is necessary to continuously squeeze the water injector of the spa blanket and inject the water inside into the blanket through the pipeline.

It is necessary to inject the water from the water injector into the blanket. At this time, the main engine will automatically exhaust the gas inside. When there is no sound in the main engine, you can unplug the pipe.
