All Jeven condensation hoods come equipped with lights and condensation baffles.
The basic material is stainless steel (AISI 304).
Covering boards to enclose the area between the top of the hood and the ceiling.

Exhaust air

The recommended exhaust flow rate is max. 250 l/s per 315 mm spigot, duct velocity 3.2 m/s. The hoods are equipped with a suitable type of condensation baffles (pressure level 30-50 Pa).
The recommended exhaust flow is 100 to 200 l/s per hood meter.

Installation

The hood shall be installed by hanging bars (f.ex. M8). These bars are not included in the delivery. Holes for the hanging bars should be drilled to the ceiling of the kitchen by using the shown fixture points.

Recommended height position of the hood is 2100-2200 mm. Install plastic protective corner profiles on the lower end.

Cleaning


Condensate baffles are detached by lifting them up slightly. Condensate baffles can be washed in the dishwasher, after which they are replaced.

Wall surfaces are cleaned in connection with the kitchen normal cleaning or if necessary separately. Cleaning is carried out with detergent for stainless steel surfaces.

Positioning of the hood

 


The size of the canopy is determined by the size of the kitchen equipment. The overhang depends on the type of equipment and the distance between the hood and the equipment. For this type of equipment, the overhang should be at least 300 mm. The typical distance between the hood side and the floor is 2100-2200 mm.

If the equipment has any doors that open upwards, make sure there is enough distance to the canopy.
