USE

Installation

The appliance may be used on any rigid horizontal surface. Do not overload the electrical circuit; avoid using the same outlet for multiple appliances.

Electrical connection

Before connecting the plug to the power outlet, make sure that the voltage of your electrical system corresponds to the voltage shown on the appliance rating label and the outlet you are going to use is in good condition.

Operation and use

• Connect the appliance to the power outlet.
• The appliance emits a beep and the power indicator light (H) comes on and remains on as long as the appliance is powered.
• The appliance goes into OFF. If the display shows a blinking dot, it means that the tip over switch has been activated. See paragraph: “Additional safety features”.
• Press the ON/OFF button (A) to turn on the appliance. It will begin to heat with the predefined settings.

MODE button

Press the MODE button (F) to select one of the following functions available:

• Ventilation
  In this operating mode only the fan operates, so the appliance does not heat the room.
• Anti-freeze
  In this operating mode the appliance keeps the room at a temperature of 45°F (7°C) to prevent freezing temperatures.
• Heating 1 and Heating 2
  In this operating mode you can set the desired temperature by pressing the + and - adjustment buttons (B).
  • Heating 1 (minimum power level):
    The appliance operates at the minimum power, reducing noise and energy consumption to the minimum.
  • Heating 2/BOOST function (maximum power level):
    The appliance operates at the maximum power for rapid heating of the room.

ECO function

In this operating mode the appliance will automatically set the power level to guarantee the best comfort reducing the energy consumption. In this operating mode the unit may switch the heating power level from maximum to minimum and viceversa, several times in an hour.

When using the ECO function, the maximum temperature setting is 79°F (26°C). To activate this function, press the ECO button (D):

• If you want the appliance to distribute the airflow over a larger area, press the oscillation button (C) . The appliance will then oscillate right and left. To stop the oscillation in the desired position, just press oscillation button (C) again.
• To turn off the appliance press button ON/OFF (A). The display will show a count down for about 6 seconds.

Please note: The display can show the temperature in both °F and °C. To change the temperature scale, press and hold the + key for around 8 seconds, then release.
Please be informed that as this is not a precision device, the showed temperature not necessary corresponds to the real one.

24 h digital timer

This function can be activated from any operating mode.

Delayed switch-on: with the appliance in the OFF position, press the timer button (E) . The display shows the symbol and the time remaining before switch-on. To set the timer, use the + and - adjustment buttons (B), then wait a few seconds for the programming to be set.
The display shows the symbol to indicate you have set the timer. When the programmed time has been reached, the appliance turns on with the same settings it had during the previous operation.

Auto-off: with the appliance on, press the timer button (E) . The display shows the symbol and the time remaining before shut-off. To set the timer, use the + and - adjustment buttons (B), then wait a few seconds for the programming to be set. The display returns to show the current settings and the symbol to indicate you have set the timer. When the programmed time as been reached the appliance shuts off automatically. If you want to go back to operation without the timer, press the timer button (E) twice. The timer symbol disappears from the display.

Inserting or replacing the batteries

• The remote control is provided with a lithium battery CR2032. To let the appliance function, remove the battery cover strip, by pulling it.
• To replace the batteries, remove the battery cover by rotating it. Replace the battery paying attention to respect the right polarity as shown in figure 2.
• Replace the cover rotating it towards the position “CLOSE”.
• Old batteries must be removed and disposed off in accordance with current legislation as they are harmful to the environment.

ADDITIONAL SAFETY FEATURES

• Overheating protection: a safety device switches the heater off if it accidentally overheats (e.g.: air intake and outlet grilles obstructed, filter clogged). In this case remove the plug from the power outlet and leave it unplugged for a few minutes, eliminate the cause of overheating, then plug the fan heater back and turn it on again. If the appliance doesn't work please contact the De'Longhi Customer Service.

Please note: To avoid overheating the appliance, do not cover it.

• Tip over safety switch: a safety tip-over switch turns the heater off if it tips over or is positioned in an improper way that could jeopardize safety. The appliance emits a beep and the display will show a blinking dot. After the appliance has been restored in the vertical position it will take just few seconds to start on again.

Alarms

The appliance has a diagnostic system that makes it possible to signal malfunctions.
In case of problems, the display will show an alarm message: (Probe failure) and (High temperature), see troubleshooting section.
