[. . . ] Please read carefully all the information provided in these instructions. Keep the instructions in a safe place and if necessary give them to any future owner. [. . . ] When installed, the heater must be aligned horizontally on a vertical wall, as shown in the illustration. In addition, a minimum distance of at least 500 mm must be maintained in front of the heater. Do not install the heater where the controls can be reached by a person bathing or showering. Ensure that air can enter and leave the heater freely, at the inlets below and the outlets above. The heater is equipped with a thermostat, by means of which the desired room temperature can be set. The setting * represents a room temperature of about 6° C (protection against freezing). Turning the thermostat knob to the right (clockwise) increases the temperature setting, while turning to the left (anticlockwise) reduces the desired temperature. Depending on the size of the room, heat requirement and thermostat setting, rooms may overheat if the heating is not controlled. This can be dangerous for people who are not able to leave the room as it gets too hot. Power supply voltage Protection class I Protection system If this occurs, switch the heater off for a few minutes (turn the switch to "0" or pull the plug out), so that the unit can cool down sufficiently. Keep the air inlets and outlets free of dust to ensure that maximum heat output is available. Before the start of the heating season, vacuum-clean the heater to remove any dirt or dust. [. . . ] Dust that collects within the unit can be removed from the outside using a vacuum cleaner. The warranty is not valid without a sales receipt marked with the date of purchase. [. . . ]
