1. At first, you need to prepare two towels, one can be placed under the vent and the other can be placed at the water outlet to prevent water from overflowing and wetting the sheets. Next, you need to prepare water pipes and screws.

2. Take out the bedspread, unzip it, lay it flat on the bedside, and lay a layer of bedding under the bed. Then take out the capsule and put it flat in the bedspread. The two nozzles should face upwards, and at the same time adjust the direction to connect the thermostat with the internal wires. The connector of wiring passes through the bedspread and is placed outside, and the place where water is injected is opened.

3. Insert one end of the water pipe into the water inlet, and then start water injection. Joints must be strong to prevent water from overflowing due to excessive pressure. As the water is slowly injected into the bed, when it is full, when it is almost full, hold down the mattress and try to drive out the air inside. The other one is laid flat on the bedspread, aligned as far as possible, then electrified, zipped up the bedspread, and water injection is completed.
