Oxygen-rich air from outside is drawn into the air intake pipe of the device. The air intake section prevents rainwater from penetrating into the housing.
The user interface of the device consists of the following elements: Liquid crystal display (LCD display), Control panel buttons, Remote control (RC), Sound warnings.
The filters should be replaced after their natural lifetime expires, or if the E11 (H11) HEPA filter is optionally replaced with an adsorption catalytic AK-XXL filter.
The LCD display will warn of any malfunctioning or contingency. Should an abnormal situation occur: the device will automatically switch to standby mode.
