This document provides instructions for use of the De'Longhi Dragon 4 Oil Filled Radiator, models TRD41500ET and TRD42400ET. It covers important warnings, operational features, and maintenance guidelines to ensure safe and effective use of the appliance.
The De'Longhi Dragon 4 is an oil-filled radiator designed to provide heating for indoor spaces. It operates by heating a precise quantity of special oil contained within its body, which then radiates heat into the room. The appliance features a control panel with a display and various buttons for setting temperature, power levels, and activating special functions.
Key components include:
The radiator is equipped with a diagnostic system that signals malfunctions through alarm messages on the display, such as "PF" for product failure or "HE" for high temperature. A safety device is also integrated to shut down the radiator in case of overheating.
Before first use, the radiator needs to be prepared. Turn the radiator upside down on a soft surface to avoid damaging the paint finish. Fully unfold the wheels by turning them outwards (as shown in Fig. 1), then turn the radiator back to its upright position.
Ensure that the supply voltage matches the rating plate of the appliance. The socket must be adequately earthed. Avoid using extension leads, as they can overheat. The appliance should not be placed immediately below a fixed socket-outlet. Do not use the radiator in rooms smaller than 4 m² (43 square feet).
To turn on the appliance, press the On-standby button (B). The display will show the "↔" symbol in standby mode. To set the desired power level, press the Power button (C) to cycle through MIN (—), MED (——), or MAX (———).
Use the Increase button (+) or Decrease button (-) (E or D) to select the desired temperature, which can be set from 5°C to 28°C. Each press adjusts the temperature by 1°C. Holding the button down will rapidly change the value.
Setting the temperature to 5°C using the "-" button activates the Antifreeze function. The display will show a "*" symbol. In this mode, the appliance will automatically turn on at maximum power only if the room temperature drops below 5°C, preventing freezing. To return to normal heating, press the "+" button once.
Press the "ECO" button (H) to activate the Eco function. The display will show the "ECO" symbol. This function automatically selects the most appropriate power level (MAX-MED-MIN-OFF) to maintain comfort while reducing energy consumption. If the selected temperature is much higher than the actual room temperature, the appliance will start heating rapidly. The appliance will cycle through power levels based on the initial power setting:
The "sss" symbol indicates the heating status by changing colors:
The appliance has two brightness settings. The highest is active when any key is pressed. After a few seconds of inactivity, the brightness decreases to an operating level, which can be adjusted by repeatedly pressing the Brightness button (G) to cycle through three available levels.
To prevent accidental operation, the keyboard can be locked. Press the "+" and "-" buttons together for at least 3 seconds. The display will show the " " symbol, and a double acoustic signal will be emitted. Repeat the process to deactivate the key lock.
The timer can be set for delayed start or delayed stop.
To switch between °F (Fahrenheit) and °C (Celsius), when the unit is in standby, press and hold the "+" and "ECO" keys for at least 10 seconds, then release. Two short beeps will confirm the change.
Before cleaning, always unplug the appliance from the mains socket and allow it to cool completely. Wipe the radiator with a soft, damp cloth. Do not use detergents or abrasive materials.
If the radiator will not be used for an extended period, wrap the cable around the cord holder and store the appliance in a dry place. Ensure it is completely cooled and unplugged before storage. Do not store it in dusty atmospheres or hang it.
The manual includes a troubleshooting section for common issues:
In case of malfunction or doubt, do not attempt to repair the appliance yourself to avoid fire or electric shock. Refer to the enclosed guarantee leaflet for service and assistance details. A safety device will shut down the radiator in case of overheating; contact Customer Experience to restart it.
