Frequently Asked Questions - WSE901BX Witt

What is the minimum distance between the hood and the cooktop?

The hood must be installed at least 550 mm above an electric cooktop and 650 mm above a gas cooktop.

How often should the metal grease filter be cleaned?

Under normal use, the grease filter should be cleaned every 2 months. In periods of intensive use (more than 4 hours per day), clean more frequently. It can be washed in a dishwasher or by hand with mild detergent.

How do I replace the carbon filter?

To replace the carbon filter: open the filter casing, remove the metal filter, detach the old carbon filter, mount a new carbon filter onto the metal filter, and reinstall the assembly. The carbon filter cannot be washed; it must be replaced every 2 months under normal use.

I Characteristics

WSE WSE 901 BX kitchen extractor hood was designed to remove kitchen fumes. It requires installation of a conduit discharging used air to the outside. The conduit (usually a pipe ∅150 mm) shall not be longer than 4-5 m.

The kitchen hood is an electrical appliance manufactured according to class II of shock protection.

It has its own lighting and an exhaust fan which can be set to one of three rotational speeds.

The hood was designed for permanent installation on a vertical wall over a gas or electric cooker.

II Components

The hood consists of the following elements (Fig. 1):

1. Hood body [A] with two glasses [B, C] equipped with lights,
2. Lower chimney [D]
3. Upper chimney with wall hanger [E]
4. Box with external motor
5. Set of mounting plugs.

IV Operating conditions

1. The kitchen hood was designed for removal of kitchen fumes to the outside. It should be connected to an appropriate ventilation duct (do not connect the hood to any chimney, smoke or flue-gas ducts which are in use).
2. The device shall be installed at the distance of at least 550 mm above the working top of an electric cooker and 650 mm - of a gas cooker.
3. Do not leave open flame under the hood. When removing pots from the burners set the flame to its minimum level.
4. Any food cooked in fat shall be constantly monitored, since overheated fat can ignite very easily.

5. The grease filter of your kitchen hood should be cleaned at least every 2 months, because a filter soaked with grease becomes easily flammable.

6. Pull the plug of the power cord from a wall socket before any cleaning, filter replacement or repair operation.

7. If any other non-electric devices are used in the same room as the hood (e.g. liquid fuel ovens, flow-through or volumetric water heaters), it is necessary to provide appropriate ventilation (air supply). Safe operation is possible when during simultaneous operation of the hood and combustion devices dependent on air supply the negative pressure of not more than 0.004 milibar is maintained at the location of these devices inside the room (this point does not apply when the hood is used as an odour absorber).
8. When connecting to 220V power supply network use an electric socket in working order

V Installation

To install the hood proceed as follows:

1. Mark on the wall minimum distance between hood and plate
2. Mark drilling holes with hood on the wall
3. Drill mounting holes and put mounting screws inside
4. Hang hood body
5. Mount vent pipe.
6. Place the box with motor [M] when you have decided (for example in the attic, above the hood)
7. Connect hood to the box with motor ∅ 150 ventilation air duct R.
8. Connect the motor power cable and power cable together.
9. Connect motor box to the vent.
10. Slide chimneys

1. Mark the appropriate height of chimney section.
2. Secure both chimneys parts.

3. Connecting to the power network and operation check

After connecting the device to the power supply network (in accordance with the requirements defined above) it is necessary to check the lighting of the hood and whether its motor works correctly.

The wall socket shall be accessible for disconnecting the plug after the hood is installed.

4. Setting the operation mode of the kitchen extractor hood

4.1 Setting the air extractor mode of operation of the hood

The hood can be connected to the opening discharging air to the outside by means of a rigid or flexible conduit of 150 mm diameter, and appropriate clamps for conduits which should be purchased in a shop selling installation materials.

A qualified installer should be commissioned to make the connection.

4.2 Fan speeds

The lowest and medium speeds should be used under normal conditions and with low concentration of fumes. The top speed should be used in case of high concentration of kitchen fumes, e.g. during frying or grilling.

VI Operation and maintenance

1. Operational safety

All safety instructions included in this manual shall be observed without exception!

Grease filters should be cleaned and replaced according to manufacturer's instructions, or more frequently in periods of intensive use (more than 4 hours a day).

If a gas cooker is used it is forbidden to leave uncovered flame. When removing pots from gas burners set the flame to its minimum level.

Always make sure that flame does not extend outside the pot. Such a situation causes undesired energy losses and dangerous heat build-ups.

The hood should not be used for other purposes than those for which it was designed.

2. Operation

2.1 Control panel

Hood can be controlled by a touch control panel:

I/O-on/off

Slider – slide your finger to select motor speed

T - timer

- dot indicating that the good is in the switch-off mode

L - lights on/off button

2.2. Program function

Timer function: WSE 901BX kitchen hood is equipped with the option of programming automatic switch-off of to maximum delay of 15 minutes. Timer" is activated by tapping „T" button during operation of the hood with the required fan speed. The dot above the T will appear indicating that the device is in the switch-off time programming mode.

TIMER function can be cancelled by pressing T button again during counting of the time.

TIMER function has to be actuated within 20 seconds, otherwise the hood will return automatically to normal operation.

The microprocessor system may get deleted or crash during momentary voltage drops in the network, and stop responding to commands from the keyboard. In such case the hood has to be disconnected from and then connected again to the power network in order to reset the system.

3. Maintenance

Regular maintenance and cleaning of the device will guarantee its good and fault-less operation, and extend its life. Attention should be paid to replacing grease filters according to manufacturer's instructions.

3.1 Metal grease filters

1. Cleaning.

Grease filters should be cleaned every two months during normal operation of the hood, in a dishwasher or manually, using mild detergent or liquid soap.

1. Replacement (Fig. 6).

To dismantle the filter proceed as follows:

a) remove the bottom cover by releasing the lock catch,
b) remove the metal grease filter

3.2 Carbon cassette filter

1. This filter is used only in the re-circulation mode. The filter contains active carbon that absorbs the ventilated odors. After a while the active carbon is saturated, and loses its absorption ability. The filter can't be washed or otherwise cleaned. Under normal use, the carbon filter should be replaced every 2 months. In case of more frequent frying or deepfrying, shorten the interval.

2. Installation

a) open the filter casing

b) remove the metal filter and remove the carbon filter from it.

c) mount a new carbon filter on the metal one, and put the set back.

d) close the filter casing.
