Using this Fisher & Paykel rangehood halogen light assembly is easy. First, make sure your rangehood is turned off and unplugged for safety. Then, carefully remove the old light assembly from your rangehood. Take the new light assembly and connect the 2 - pin male connector to the appropriate socket in the rangehood. Gently place the light assembly in the designated spot. Once it's in place, you can turn on your rangehood and enjoy the bright light. As for maintenance, keep the light and the lampholder clean. You can use a soft, dry cloth to wipe off any dust or dirt. When the halogen globe burns out, replace it with a new 12 - Volt, 20 - Watt halogen globe. Always remember to turn off the power before replacing the globe. Also, if you notice any damage to the light assembly or the wiring, stop using it and contact a professional for help.
