3.Installation
●Surrounding environment
Range hood shall be avoided to be installed at the place where there are many doors and windows since it will cause
too large cross-ventilation so as to influence the oil fume exhaust effect.
●Tool preparation
The following tools shall be prepared when range hood installation: 1. Electric impact drill (with drill);
2.Wrench; 3.Screw driver; 4.Ruler
3.1 Preparation Before Installation
The hood shall be installed right above the hob. The minimum distance between the bearing surface of cooking
appliance and the lowest part of hood is 650mm (larger space specified in the installation instruction of gas hob shall
be considered, if any; the distance for electric cooker may be reduced appropriately, depending on the actual situations) .
