NOTICE TO THE INSTALLER OR PURCHASER
As indicated on the box, the hood should be connected and tested prior to installation; if the hood works properly at that time but a problem arises after installation, the problem is not due to the hood but to improper installation somewhere between the hood and the outside vent.
Types of malfunction:
- Noise and vibrations from the hood
- The motor makes a screeching sound and seems to be forcing
- The suction power seems to be approximately the same for all settings.
Check the vent
- The most common problem is range hood flaps that fail to open:
- Did you remove the protective adhesive strip on the flaps?
- Did you install the duct too tightly over the flaps, preventing them from opening fully?
- Never use screws to attach the duct to the hood outlet. Use duct tape instead
- To quickly check whether the valves are operating properly, run the hood for 30 second then turn it off. After 2 or 3 seconds, you should hear the two flaps close one after the other.
- The duct connecting the hood to the outside should be the same diameter as the hood’s outlet (typically 6 inches) and be free of obstacles.
- Caution! Never put an angled duct right at the outlet of the hood.
- Use the following vents
• SOFFIT VENTS • WALL VENTS
CAUTION! DO NOT USE THESE VENTS
• HEATING SYSTEM GRILLE • ROUND VENT (for bathroom fans)
- If the hood is mounted on a glass-ceramic wall, it may seem noisy at the lowest setting. This can be fixed by installing a piece of 1/2-inch foam rubber between the hood and the wall.
