    FAQ

    Q: Does this product work with batteries or solar energy?

    A: no battery. There is no solar energy. It works by temperature. If the temperature of the greenhouse rises. Then the gas in the gas field will become hot. And because of the increase in pressure, push it out (windows open). If the temperature drops again (air f cooling). The spring pushes the gas rod back into the cylinder (the window is closed).

    Q: Why the window does not work when the window opener is installed?

    A: There are several situations

    1. The installation method is wrong, and it is not installed correctly according to the instructions

    2. If the cylinder is stuck, you can use oil droplets on the inner side of the cylinder thread, and then manually stretch the cylinder several times

    3. If the above methods are not applicable, please put the cylinder in 35-45 degree water for 30 minutes. If the air cylinder is extended after 30 minutes, it means that the cylinder can operate normally (it may be that you installed it wrong, and then install it again according to the instructions. ), if there is no extension, it means the cylinder is damaged.
