RANGE HOOD OPERATING INSTRUCTIONS

Before using this range hood, please read these instructions completely.

PREPARATION FOR INSTALLATION

Please read the following carefully before installing your Range Hood a quality home appliance. Installation will be much easier if you have read this important note.

1. It is not difficult to install the Range Hood if you have a proper exhaust duct going outside your home. You should also have appropriate tools for installation use. Generally, with a proper exhaust duct and tools, it only takes about 2 hours to install the Range Hood.
2. The Range Hoods are available in round can be connected to round exhaust duct. Please check your exhuast duct and the vent of your existing range hood (if you have one):

(1)No exhaust duct:
If you do not have an exhaust duct going outside your home, please hire a professional to install one for you.
(2)Round exhaust duct:
A. Round vent-round exhaust ductExplanatory Notes Figures A
A. Round vent-round exhaust duct:
In this case, installation is the easiest and exhaust performance is the best. Please measure the circumference of the exhaust duct with a rope:
If the circumference is 32cm, the diameter of the exhaust duct will be 4″,
If the circumference is 40cm, the diameter of the exhaust duct will be 5″,
If the circumference is 48cm, the diameter of the exhaust duct will be 6″,
If the circumference is 56cm, the diameter of the exhaust duct will be 7″.
The vent of the Range Hoods is 6″ in diameter. If your exhaust duct is not 6″ in diameter, you have to buy a connecting duct to connect the exhaust duct to the vent.
Please note that if your exhaust duct is 4″ or less in diameter, the performance of your Range Hood will be greatly affected.
3. Tools and Materials Required

• Pliers (for opening electrical knockout);
• Heavy duty cutter (for cutting metal plate);
• Electrical supplies for the wiring;
• Heat resistant tape (for taping the connection between the vent and the exhaust duct);
• Pencil and ruler (for marking locations);
