The Varna rat repellent has to be fixed within the Chevrolet engine bay, facing towards the hood. The repellent speaker should be slightly tilted towards the left to reflect the ultrasonic frequency throughout the engine bay.


Connect the repellent wires to the battery terminals.


If the bonnet has heat insulation pad within, paste the aluminium sticker just opposite the repellent to re-bounce the ultrasonic sound throughout the engine bay.
