Technical data

Before installation, you must first connect the dual fan and check if the fans rotate, so you can see in which direction the airflow is being drawn in or out.

The refrigerator fan should be installed in the upper air vents of your motorhome, ideally so that the hot, exhausted air can be vented outside. If installed in the lower air vents, the double fan could obstruct the gas supply when the refrigerator is running on gas.

For installation in the upper ventilation system:

Make sure the top of the fan (the one with the stickers and the blue TITAN logo) is facing inwards (towards the interior of the vehicle), so that the used hot air from the vehicle is drawn outwards.

For mounting on the lower ventilation grille:

Proceed in reverse order, that is, mount the fan assembly with the top part (the side with the stickers and the blue TITAN logo) facing outwards; this way, cool air will be pushed towards the cooler.

Temperature sensor installation:
The temperature sensor should be mounted approximately 5 cm above the refrigerator's cooling fins so that it hangs freely. DO NOT attach the sensor directly to the refrigerator's cooling fins!

In any case, after installing the dual fans, it is advisable to reinstall the vehicle grille, especially if it is installed on the lower vent grille, to protect the fan blades and avoid any risk of injury.

Operating instructions for speed control

Manual operation

In manual mode, only the blue LEDs are illuminated. The fan speed can be increased or decreased in 6 levels by pressing the + or – buttons. Each press increases or decreases the speed by one level. The number of illuminated blue LEDs depends on the selected speed level.

Automatic operation

In automatic mode, the green light illuminates as soon as the fans start spinning. The fans activate automatically when the ambient temperature exceeds 20°C. Between 20°C and 45°C, the fans operate according to the temperature. Above 45°C, the fans automatically operate at maximum speed.

Below 20°C, the fans automatically stop and the LED stops shining green and starts shining red.

If no LED lights up (neither blue, nor green, nor red), the fan is completely off.
