Extraction Mode / Recirculation Mode - Pkm UBH 4060-2H Bedienungsanleitung

4. If your appliance is equipped with a carbon filter, remove the carbon filter before
you operate the appliance in the extraction mode. The carbon filter should be
used in the recirculating mode only.
5. The exhaust duct should be as short and straight as possible. The diameter of the
exhaust hose should be at least 120/150 mm (look at chapter T
Otherwise you have to expect increased noise and decreased performance of your
appliance.
6. The proper maximum bending angle outwards is 120
7. Use smooth tubes or flexible, non-inflammable exhaust hoses only.
8. When the exhaust duct is connected horizontally, a minimum falling gradient of
1 cm/m or an inclination of 2
motor of the hood.
9. When an exhaust duct is used, the ending of the exhaust hose must be adjusted
into the direction of flow.
10. If the exhaust duct passes through cool areas (e.g. an attic), a temperature gradient
may occur in the different parts of the exhaust duct so condensate will be
generated. Proper insulation of the corresponding parts of the exhaust duct will
then be needed. Equip such an exhaust duct with a condensate trap if need be.

2.1 Extraction mode / recirculation mode

❖ The appliance is suitable to be operated in extraction (vertical exhaust opening or
horizontal exhaust opening) or recirculation mode (without exhaust opening).
➢ The appliance is equipped with two exhaust openings (vertical exhaust opening
(A) / horizontal exhaust opening (B), s. fig. below).
