Electrical Connection

This heater must be used on an A.C. ~ supply only and the voltage marked on the heater must correspond to the supply voltage.

This heater is fitted with a plug incorporating a 13 amp fuse. When replacing the fuse, a 13 amp fuse approved by ASTA to BS 1362 must be used.

If the plug is not suitable for the socket outlets in your home, the plug must be cut off and an appropriate one fitted. A plug cut off from a mains lead will give a shock hazard if inserted into a 13 amp socket elsewhere in the house. To avoid this, it should be disposed of immediately.

NOTE: The fuse cover of a non-rewirable plug must be refitted when changing the fuse. Should the cover become lost, the plug must not be used until the correct replacement fuse cover is obtained from your supplier or by contacting the customer helpline.

IMPORTANT: The wires in this mains lead are coloured in accordance with the following code:

• BLUE: NEUTRAL
• BROWN: LIVE
• GREEN & YELLOW: EARTH

As the colours of the wires in the mains lead may not correspond with the coloured markings in your plug, proceed as follows:

Connect the BROWN wire to the terminal marked 'L' or coloured RED. Connect the BLUE wire to the terminal marked 'N' or coloured BLACK. Note: 'L' or 'N' must not be connected to the EARTH terminal marked 'E' or coloured GREEN or GREEN AND YELLOW. If in doubt, consult your electrician.

2. Insert a CR/2025/3V button cell battery with the positive terminal facing upwards.
3. Replace the cover.

(Diagram illustrates the process of opening the battery compartment and inserting a battery.)

Heating Mode

The heater offers three heating modes:

• Intelligent Eco Heat: Automatically regulates room temperature for optimal energy use. The product operates at full power, but output is reduced as the desired temperature is approached.
• High Heat: Operates at a high heat setting, cycling to maintain the set temperature. Fan speed is automatically set to Medium.
• Low Heat: Operates at a low heat setting, cycling to maintain the set temperature. Fan speed is automatically set to Low.

Frost Protect: When set to 5°C, the Frost Protect symbol appears, and the product cycles on/off to maintain approximately 5°C to protect against frost.

Temperature Setting: Temperature can be adjusted between 5°C (41°F) and 30°C (86°F).

Note: If the set temperature is lower than the room temperature, the product will shut off, indicated by flashing temperature. It will remain in this state until the room temperature drops or the set temperature is increased.

(Diagrams show the control panel display for different heating modes and temperature settings.)

Fan Speed (Cooling Only)

In cooling mode, the fan speed can be adjusted through three settings:

• Low Speed: Provides a low level of cooling effect.
• Medium Speed: Provides a medium cooling effect.
• Turbo Speed: Provides maximum cooling effect.

Default Fan Speed: Low. When only the fan is running, the display cycles through three states to resemble a rotating fan blade.

(Diagrams show the fan speed icons and their corresponding descriptions.)

Runback Timer

The Runback Timer can be set in cooling or heating modes, ranging from 1 to 12 hours.

Setting the Timer:

1. Press the Runback Timer button. The icon will flash for 6 seconds.
2. Use the '+' and '-' buttons to increase or decrease the runback time.
3. After 6 seconds, the set time will be confirmed, and the icon will be solid while the timer is active.

Viewing Current Timer: Press the Runback button to view the remaining time.

Cancelling the Timer: Go back into the runback settings and change the time to 0, or press the Standby button.

(Diagrams illustrate setting and cancelling the runback timer.)

Oscillation

The oscillation feature provides heating and cooling across a wider area.

• Oscillation ON: Product will oscillate, and the oscillation icon will be visible.
• Oscillation OFF: Product will be static, and the icon will be off.

Press the oscillation button to cycle between ON and OFF.

(Diagrams show the unit oscillating and the control panel display for oscillation.)

(Diagrams show correct and incorrect cleaning methods.)

Air Filter

This heater is provided with an air filter designed to remove dust particles, fluff, and hair to enhance air quality.

• It is recommended to remove and clean the filter regularly to avoid overheating of the element.
• To clean the filter, remove the filter cover from the back of the heater and shake it outside.
• Alternatively, you can wash the filter in warm water and allow it to dry naturally for 24 hours.
• Replacement filters are available from www.dimplex.co.uk/spares.

(Diagram shows the air filter being removed and cleaned.)

Temperature Units

Temperature units can be changed between Celsius (°C) and Fahrenheit (°F).

• Press and hold the '-' and '+' buttons for 2 seconds to change the temperature units.
• The displayed temperature will update accordingly.
• Minimum temperature setting: 5°C (41°F).
• Maximum temperature setting: 30°C (86°F).

(Diagrams show the control panel displaying temperature in Celsius and Fahrenheit.)

Key Lock

The Key Lock function disables most buttons on the control panel, except for Standby.

• Keylock ON: All buttons (apart from standby) are inactive, and the Keylock icon will be On.
• Keylock OFF: All buttons will be active, and the icon will be Off.

Press and hold the relevant button for 2 seconds to activate or deactivate Keylock.

Note: Inactive buttons will not beep when pressed.

(Diagrams show the control panel display with and without Keylock active.)

Tilt Switch

The product is fitted with a safety tilt switch that prevents the heater from working if it is accidentally tipped over in any direction.

The tilt switch mechanism may make a muted rattling noise when the product is moved or tilted; this is normal and not a fault.

The product should only be operated on a flat, stable surface.

(Diagram shows the unit tilted at 45 degrees with a warning symbol.)

Supplementary Information

Control Panel Intensity

The control panel display remains visible at all times and cannot be switched off for safety reasons, ensuring visibility in poor light conditions. The display reduces its intensity by 50% after 10 seconds of inactivity but brightens temporarily when a button is pressed.

Overheat Protection

The heater is fitted with a temperature limiter. If the air inlet or outlet grilles are restricted, the temperature limiter will automatically switch the heater off. To restart, remove the cause of overheating, unplug the unit from the electricity supply for a few minutes, then reconnect and switch on.

Remote Batteries

To insert or replace the remote battery, remove the cover on the rear of the remote, insert a CR/2025/3V button cell battery with the positive terminal facing upwards, and replace the cover.
