Installation and startup of the aeration kit:

1. First, you need to choose a location for the air blower. We recommend placing the air blower as close to the body of water as possible. This will help avoid greater air flow losses. The air blower can operate outdoors, but it must be protected from direct precipitation and severe frost. Install the air blower in a sealed box (metal, plastic, or wooden). The box does not need to be insulated, but openings must be left for air to enter inside. If there is a gazebo, sauna hut, or another structure near the body of water, install the air blower there. In either case, ensure safe and reliable power supply to the air blower.
2. Hose. Use a PVC or rubber pressure hose with an internal diameter of 10 mm purchased from us or one you already have (the hose must be reinforced. Do not use a very soft hose that kinks easily). We recommend using a hose no longer than 25 m. Fit one end of the hose onto the air blower outlet nozzle and tighten it carefully with the supplied clamp. Fit the other end of the hose onto the check valve and also tighten it well  with the clamp. In the kit, you will already find the check valve connected to the diffuser. If you will use the aeration kit  during the warm season as well, you can remove the check valve from the system. In that case, connect the hose directly to the air diffuser. This will help avoid additional pressure losses. The system is ready.
3. Submerging the air diffuser. We recommend submerging the diffuser as deep as possible (just do not exceed the maximum allowable submersion depth). The higher the water column above the diffuser, the better the air bubbles and the oxygen in them dissolve in the water, and the mixing of different water layers takes place. The ring-shaped air diffuser is lighter than water. To submerge it, tie a synthetic rope at the hose connection point to the diffuser, and attach a weight to the other end of the rope (recommended weight 0.5 - 1 kg). Submerge the prepared diffuser with the weight into the selected location in your body of water. The weight will lie on the bottom of the water body, and the diffuser will rise as much as the left rope length allows.  The recommended minimum rope length between the weight and the diffuser is 10-15 cm. This way, the diffuser will not stir up bottom sediment during operation and will not make your body of water murky. By adjusting the rope length between the weight and the air diffuser, you can adjust the diffuser submersion depth. Other methods of submerging the diffuser are also possible, but this one is the simplest and works perfectly.
4. Plug the air blower into the mains and the aeration system will start operating. If there is no need to aerate 24 hours a day, purchase a timer and set the operating mode you need. The aeration system is designed to operate in both continuous and intermittent mode. Enjoy using it.
