Calculating length of elbow vent pipe evacuation* :
30 Pa = 1 ml duct
30 Pa = 1 90 ° elbow
•
The length of vent pipe between the hood (sensor) and the separate motor determines the average pres-
sure in pascal (Pa) that the separate motor is provided, and inverse.
Example :
Type of protection: category 1
Power supply voltage: 220-240V mono - 50/60Hz.
Check that the voltage of the supply circuit is identical to the values indicated on the descriptive plate inside the hood.
If the hood is directly connected to the network (without its plug), an omnipolar switch with a 3mm contact point-gap should
be installed just before the hood. The earth wire (yellow and green wire) should not be interrupted by this switch.
TECHNICAL FORM
eg to 3 m hose and 2 90 ° elbows vent pipe between the hood and
separate motor requires a mean pressure of 250 Pa
ELECTRICAL
The hood requires a power of 220-240V
