Frequently Asked Questions - DA 921 DF Dominox

How do I install the Dominox DA 921 DF range hood?

Installation should be done by a qualified professional. Ensure the hood is at least 65 cm above the cooktop for gas hobs and 50 cm for electric. Fix the bracket to the wall, hang the hood, and connect to the duct or recirculation system. Refer to the user manual for detailed steps.

How often should I clean the grease filter?

Clean the aluminum grease filter every month or after 30 hours of use. Soak in warm water with mild detergent, rinse, and dry before reinstalling. Do not use abrasive cleaners.

Can I use the hood in recirculation mode?

Yes, if your kitchen does not have external ducting. You will need a charcoal filter (not included). Install it behind the grease filter. Replace the charcoal filter every 3-6 months depending on usage.

Why is my range hood making excessive noise?

Excessive noise may indicate clogged filters, loose parts, or improper installation. Check and clean the grease filter. Ensure all screws are tight. If noise persists, contact a professional.

How do I replace the LED lights?

The LED lights are typically non-replaceable by the user. If they fail, contact Dominox customer service or a qualified technician for replacement parts.

What is the maximum extraction rate?

The Dominox DA 921 DF has a maximum extraction rate of approximately 650 m³/h in ducted mode. Performance may vary based on duct length and bends.

How do I reset the filter alarm?

After cleaning or replacing filters, press and hold the timer button for 3 seconds until the indicator light turns off. Refer to the manual for exact steps.

Does the hood have a remote control?

The Dominox DA 921 DF typically does not include a remote control. All functions are controlled via the panel buttons.

What should I do if the hood stops working?

Check the power supply and circuit breaker. Ensure the hood is properly connected. If still not working, contact Dominox support. Do not attempt to repair the motor yourself.

Is the charcoal filter washable?

No, charcoal filters are not washable. They must be replaced every 3-6 months. Do not attempt to clean them, as this reduces effectiveness.

The Instructions for Use apply to several versions of this appliance. Accordingly, you may find descriptions of individual features that do not apply to your specific appliance.

INSTALLATION

• The manufacturer will not be held liable for any damages resulting from incorrect or improper installation.
• The minimum safety distance between the cooker top and the extractor hood is 650 mm (some models can be installed at a lower height, please refer to the paragraphs on working dimensions and installation).
• Check that the mains voltage corresponds to that indicated on the rating plate fixed to the inside of the hood.
• For Class I appliances, check that the domestic power supply guarantees adequate earthing. Connect the extractor to the exhaust flue through a pipe of minimum diameter 120 mm. The route of the flue must be as short as possible.
• Do not connect the extractor hood to exhaust ducts carrying combustion fumes (boilers, fireplaces, etc.).
• If the extractor is used in conjunction with non-electrical appliances (e.g. gas burning appliances), a sufficient degree of aeration must be guaranteed in the room in order to prevent the backflow of exhaust gas. The kitchen must have an opening communicating directly with the open air in order to guarantee the entry of clean air.

USE

• The extractor hood has been designed exclusively for domestic use to eliminate kitchen smells.
• Never use the hood for purposes other than for which it has been designed.
• Never leave high naked flames under the hood when it is in operation.
• Adjust the flame intensity to direct it onto the bottom of the pan only, making sure that it does not engulf the sides.
• Deep fat fryers must be continuously monitored during use: overheated oil can burst into flames.
• Do not flambè under the range hood; risk of fire
• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

MAINTENANCE

• Switch off or unplug the appliance from the mains supply before carrying out any maintenance work.
• Clean and/or replace the Filters after the specified time period (Fire hazard).
• Clean the hood using a damp cloth and a neutral liquid detergent.

Wall drilling and bracket fixing

Wall marking:

• Draw a vertical line on the supporting wall up to the ceiling, or as high as practical, at the centre of the area in which the hood will be installed.
• Draw a horizontal line at 650 mm above the hob. Place bracket 7.2.1 on the wall as shown about 1-2 mm from the ceiling or upper limit aligning the centre (notch) with the vertical reference line.
• Mark the wall at the centres of the holes in the bracket.
• Place bracket 7.2.1 on the wall as shown at X mm below the first bracket (X = height of the upper chimney section supplied), aligning the centre (notch) with the vertical line.
• Mark the wall at the centres of the holes in the bracket.
• Mark a reference point as indicated at 116 mm from the vertical reference line and 320 mm above the horizontal reference line.
• Repeat this operation on the other side.
• Drill 8 mm diameter holes at all the centre points marked.
• Insert the wall plugs 11 in the holes. Fix the brackets using the 12a (4.2 x 44.4) screws supplied.
• Insert the two screws 12a (4.2 x 44.4) supplied in the hood body fixing holes, leaving a gap of 5-6 mm between the wall and the head of the screw.

Mounting the hood body

• Before attaching the hood body, tighten the two screws Vr located on the hood body mounting points.
• Hook the hood body onto the screws 12a. Fully tighten support screws 12a.
• Adjust screws Vr to level the hood body.

Connections

DUCTED VERSION AIR EXHAUST SYSTEM

When installing the ducted version, connect the hood to the chimney using either a flexible or rigid pipe with a diameter of 150 or 120 mm, the choice of which is left to the installer.

• Ensure that the activated charcoal filters have been inserted.

ELECTRICAL CONNECTION

• Connect the hood to the mains through a two-pole switch having a contact gap of at least 3 mm.
• Remove the grease filters (see paragraph Maintenance) being sure that the connector of the feeding cable is correctly inserted in the socket placed on the side of the fan.

Chimney assembly

Upper chimney section

• Slightly widen the two sides of the upper chimney and hook them behind the brackets 7.2.1, making sure that they are properly housed.
• Secure the sides to the brackets using the 4 screws 12c (2,9 x 9,5) supplied.

Lower chimney section
