Frequently Asked Questions - DHO8122TB Defy

How do I assemble the wheels on my Defy DHO8122TB heater?

Unpack the heater and locate the wheel-holding plate and butterfly nuts. Ensure the heater is unplugged and turned off. Turn the heater upside down. Attach the wheel-holding plates: one U-plate between the last two fins, the other under the metal control box. Fix the castors onto the vertical axis of the wheel-holding plates. Insert and tighten the butterfly nuts securely. Turn the heater upright. The heater is now ready to use. Do not operate without wheel assemblies attached.

What should I do if the heater overheats and shuts off?

The heater has a thermal cut-off safety feature. If it overheats, turn the heater off, unplug it, and inspect for any objects blocking the air intake or exhaust. Remove any obstructions. Allow the heater to cool for a few minutes, then plug it back in and resume normal operation.

How does the tip-over switch work?

The tip-over switch automatically shuts off the heater if it is accidentally tipped over. Once the heater is returned to its upright position, it will resume normal operation.

What modes are available on the DHO8122TB?

The heater has four working modes: Normal Mode (adjustable temperature and power level), Fast-Heating Mode (high power for rapid heating), Energy Saving Mode (default 22°C, not adjustable), and Anti-Freezing Mode (default 5°C, adjustable level only).

How do I set the timer on the heater?

To set a timed off: while the heater is on, press the timer button, then turn the knob to set the hours (0-24). After 3 seconds of inactivity, it saves. To set timed on: while the heater is off, press the power button, then adjust the time similarly. Setting to 0 cancels the timer.

Can I use the heater in a bathroom or outdoors?

No. The heater is designed for indoor household use only and should not be used in bathrooms, laundry areas, or similar moist locations. Do not use outdoors or near water.

How do I clean the heater?

Disconnect the heater from the power supply and allow it to cool. Wipe the surface with a soft damp cloth. Do not use detergent, abrasives, or sharp tools that could damage the paint. Regular cleaning helps maintain radiating efficiency.

What type of batteries does the remote control use?

The remote control requires 2 x AAA batteries (not included). Insert them with the correct polarity. Remove batteries if the remote will not be used for a long time.

What should I do if the heater does not turn on?

First, check that the power cord is plugged into a working outlet and the power switch on the heater is set to 'On'. Ensure the heater is not in standby mode. If the thermal cutoff or tip-over switch has activated, reset as described. If it still does not work, contact customer care at 086 100 3339.

Is the heater safe to use around children and pets?

Warning: Some parts become very hot. Keep children and vulnerable people away. Do not let bare skin touch the heater. Place the heater at least 0.9 meters (3 feet) away from combustible materials like furniture and curtains. Always supervise use around children.
