Please note:

This symbol indicates recommendations and important information for the user.


When using any electrical appliance, some basic safety precautions should always be observed to reduce the risk of fire, electric shock, and/or injury to persons. Read all instructions carefully before using the appliance.



- Use this appliance only as described in this manual. Any other use not indicated by the manufacturer may cause fire, electric shock, or injury to persons.

- To prevent current overload and blown fuses, make sure that no other appliance is plugged into the same outlet or into another outlet wired into the same circuit.

- CAUTION: To prevent electric shock, make sure the wide prong of the plug is inserted in the wide slot of the outlet.


- The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the appliance.

- Do not operate the appliance with a damaged cord or plug, after faulty operation, or when it has been dropped or damaged in any way.

Contact the nearest authorized service facility for examination, electrical or mechanical adjustment, or repair.

- Do not use the appliance outdoors.

- If the power cord is damaged, to reduce the risk of malfunction it must be replaced by the manufacturer, its service agent, or a licensed and qualified professional.

- Make sure that the plug is fully inserted into the outlet.

Wall outlets may deteriorate with time, so check the plug periodically for signs of overheating or deformation. If the outlet has deteriorated, stop using it and have it repaired.

- Check that neither the appliance nor the power cord have been damaged during shipping.

- Do not place the heater near a bed because objects such as pillows or blankets can fall off the bed and be ignited by the heater.


Danger of burns!!

- This appliance gets very hot when in use.

To prevent burns, do not touch hot surfaces with bare skin. Use the handle when moving the appliance. Keep all flammable materials, such as furniture, pillows, bedding, paper, clothing, and curtains at least 3 feet (90 cm) from the front and top of the appliance, also avoid contact with the sides and back.

- Do not run the power cord under carpeting.

Do not cover cord with throw rugs, runners, or the like.

Keep the cord away from any passageways where it could be tripped over.

- To prevent a possible fire, do not block air intake or air outlet grille in any way.

Do not use the appliance on soft surfaces, such as beds, where the openings may become blocked.

- To prevent overheating and the risk of fire, do not cover the appliance while it is in operation.

- The internal parts of the appliance can become very hot or produce sparks during operation. Do not use the appliance in areas where gasoline, paints, or other flammable liquids are used or stored.

- It is normal for heater’s plug and cord to feel warm to the touch. However, an excessively hot or deformed plug or cord is not normal and may be the result of a defective electrical outlet.

Defective outlets must be replaced before using the heater. Plugging the heater into a worn outlet may result in overheating of the power cord or may cause the risk of fire.

- Make sure that no styrofoam or other packing materials remain in the appliance.

- The first time the appliance is used, run it at the maximum power for at least two hours.

During this time, ventilate the room thoroughly to eliminate the “new” smell released by the appliance. It is completely normal for the appliance to emit “creaking” sounds the first time it is run.

- Extreme caution is necessary whenever the heater is left operating unattended.

- Do not open the appliance. No userserviceable parts inside.

Fitting the wheels

Turn the radiator upside down on a rug or soft surface to prevent damaging the paint finish. Fully unfold the wheels by turning them outwards (Fig. 1). Turn the radiator back to its upright position.

Fig. 1

Please note:

- Always disconnect the plug from the power outlet when the appliance is not in use.

- Do not wrap the cord around the appliance immediately after use.

- Do not use this appliance with an extension cord or power strip. Connect the appliance directly to a suitable outlet.


Always operate the heater in upright position only (wheels on the bottom, controls on top).

Any other position could create a hazardous situation.



The heater must not be placed immediately below a power outlet. Do not use this radiator in rooms having a surface area of less than 43 square feet (4 sq.m.).


To completely shut the appliance off, turn the power selector to the "0" position and then unplug the appliance from the outlet.


The radiator should be connected to a properly polarized A/C

110/120 V household outlet in perfect working condition.

Keep loose clothing or bedding, furniture and flammable material away from the heater's wall outlet.

Your product is equipped with a polarized alternating current line plug (a plug having one prong wider than the others). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not attempt to modify the plug to bypass this safety feature.


Clock setting

The program/timer, as with all clocks, must be set to the correct time. If for example the time is 9:30 a.m. (day zone), rotate the dial clockwise (following the direction of the arrow) until 9:30 is aligned with the triangular pointer.



The timer is like an electric clock, and will only work when plugged into a power supply. When unplugged, the timer stops and must be later re-set.

How to use the timer

Turning on

Insert the plug into an electrical outlet, rotate the thermostat knob to maximum and turn the unit on as follows using the power selector:

- Turn the power selector to position MIN to select minimum output (the min light will be on).

- Turn the power selector to position MED to select medium output (the min/med light will be on).

- Turn the power selector to position MAX to select maximum output (the lights will be on).

Adjusting the thermostat

When the room has reached the desired temperature, turn the thermostat dial slowly in an anti-clockwise direction until you hear a "click" and not beyond it. The thermostat will then adjust the set temperature automatically and keep it constant.

If your unit is a three-output version, in intermediate seasons or on days when temperatures are not particularly cold, select minimum output to optimize savings and consumption.

Antifreeze function

Turn the thermostat dial to the position and the power selector to position MAX. The appliance will maintain a minimum room temperature of approximately 41°F

(5°C), thus preventing freezing while conserving energy.

In models that come with a timer, tabs must be set in the inward position.

To program heating, proceed as follows:

- Look at the time on your clock or watch. If it is 10 p.m., turn the numbered timer disk clockwise until the number 22 (10 p.m.) on the disk coincides with the pointer s ( 3 ) on the timer. Set the periods of time when you want the appliance to work by pushing the teeth ( 1 ) inward. Each tooth ( 1 ) corresponds to a period of 15 minutes. This will leave visible sectors which correspond to the periods of operation ( 2 ).

When set, the radiator will operate automatically each day during the times programmed (important: the radiator must always be plugged into the socket).

- To change the programming, move the teeth back into the initial position and set the new periods of operation.

- If you want to make the appliance operate without programming, push all the teeth inward. In this case,


to turn the appliance off completely, as well as turning the knob to the off position, you must also unplug it from the power outlet to avoid continued operation of the timer.


A safety device switches the heater off in the event of overheating. Please call the De Longhi customer service.


Always remove the plug from the power outlet and allow the radiator to cool. Wipe radiator with a soft damp cloth, do not use detergents and abrasives.

Should the radiator not be in use over a certain length of time, wind the cord around the cord holder and store it in a dry place. This appliance has been built to give many years of trouble free service. In case of malfunction or doubt, do not try to repair the heater by yourself: this may result in a fire hazard or electric shock. Call the De'Longhi Customer
