Frequently Asked Questions - K90HERCRA BERTAZZONI

How do I install the Bertazzoni K90HERCRA range hood?

Installation should be performed by a qualified professional. Ensure the hood is mounted at least 65-75 cm above the cooking surface. Connect to a 150 mm duct or use recirculation mode with charcoal filters. Follow the manual for electrical connection.

Can I use the hood in recirculation mode?

Yes, the K90HERCRA can be used with charcoal filters for recirculation. You must purchase the charcoal filter kit separately and install it as per instructions.

How often should I clean the grease filters?

Grease filters should be cleaned every month or more frequently if used heavily. They are dishwasher safe; wash at low temperature and dry thoroughly before reinserting.

How do I replace the charcoal filter?

Charcoal filters should be replaced every 3-6 months depending on usage. Remove the grease filters first, then slide out the old charcoal filter and insert the new one. Reattach grease filters.

What type of light bulbs does the hood use?

The hood uses 2 x 3 W LED bulbs (G4 base). To replace, turn off power, carefully remove the old bulb and insert a new one. LED bulbs have a long lifespan.

Why is my range hood noisy?

Noise can be due to loose parts, dirty filters, or ducting issues. Ensure filters are clean and properly installed. Check for any loose screws or vibration. At max speed, the normal noise level is about 62 dB.

How do I change the fan speed?

Use the control panel buttons. Press the speed button to cycle through low, medium, and high speeds. An indicator light shows the selected speed.

What is the duct size required for this hood?

The outlet diameter is 150 mm (6 inches). Use rigid or flexible ducting of the same size for optimal airflow. Ensure the duct path is as short and straight as possible.

Is the hood suitable for island installation?

Yes, the K90HERCRA is designed for both wall and island installation. For island use, you will need a chimney extension kit (sold separately) to reach the ceiling.

Where can I find spare parts or accessories?

Spare parts such as filters, bulbs, and chimney extensions are available through authorized Bertazzoni dealers or online parts retailers. Use the model number K90HERCRA for exact compatibility.

2. INSTALLATION INSTRUCTIONS

This hood has been arranged to be installed above a cook top. It can be used in 2 ways:

• EXHAUST MODE: the kitchen vapours are purified by the metal anti-grease filters and carried outside through a ducting system. (Fig. 3A; 3B)
• RECIRCULATING MODE: the kitchen vapours are purified by the metal anti-grease filters and an activated carbon filter (sold separately), then conveyed back into the kitchen. (Fig. 3C)

We suggest to have installation carried out by qualified personnel, in compliance with all the current regulations and in particular with the ones concerning air exhaust and electrical connection. The manufacturer cannot be held liable for damages caused by improper installation or if it has not been carried out according to the state-of-the-art.

2.1 ELECTRIC CONNECTION

The appliance has been manufactured as a class II, therefore no earth cable is necessary.

The connection to the mains is carried out as follows: BROWN = L line

BLUE = N neutral

If not provided, connect a plug for the electrical load indicated on the description label. Where a plug is provided, the cooker hood must be installed in order that the plug is easily accessible.

An omnipolar switch with a minimum aperture of 3 mm between contacts, in line with the electrical load and local standards, must be placed between the appliance and the network in the case of direct connection to the electrical network.

2.2. INSTALLATION

The appliance must be installed at a minimum height of 650 mm from an electric cooker stove, or 750 mm from gas or combined cooker stoves. (Fig.1) If a connection tube composed of two parts is used, the upper part must be placed outside the lower part.

Do not connect the cooker hood exhaust to the same conductor used to circulate hot air or for evacuating fumes from other appliances generated by other than an electrical source.

2.3. MOUNTING THE COOKER HOOD TO THE WALL Drill holes A-B-C according to indications quoted in (fig.1).

Use screws and screw anchors suitable for wall (e.g. reinforced cement, plasterboard) for the mounting of the cooker hood. Where screws and screw anchors are supplied ensure that they are suitable for the type of wall where the cooker hood is to be mounted.

Affix the bracket Z to the wall via the drill holes C Hang the cooker hood on the wall using the drill holes A.

Fasten the cooker hood using the fastening drill holes B.

2.4. EXHAUST VERSION

Connect the flange Y to the discharge opening with a connecting tube Fig.5 (do not carry out for filter version).

Thread the upper connector E to the inside of the lower connector F; hang the two connectors inserting them vertically on the cooker hood, unthread the upper connector E towards the top, locking it in with the appropriate screws in the drill holes G of the bracket Z (fig. 7) previously affixed to the wall via the drill holes C (fig. 1).

2.5 RE-CIRCULATING VERSION

In order to transform your cooker hood from the exhaust version to the re-circulating version, ask your local retailer for active carbon filters and then carry out the following instructions.

The filters must be applied to the suction kit located inside the cooker hood (fig. 6). The air is replaced in the environment via the eyelets impressed on the connector E.

2.6. OPERATING CHECKS

Check lights and motor start-up on all speeds.

USE AND MAINTENANCE

It is recommended to switch on the appliance before cooking. It is also recommended to leave the appliance in operation for 10 minutes after cooking is terminated in order to completely eliminate cooking vapours and odours.

The proper function of the cooker hood is conditioned by the regularity of the maintenance operations, in particular, the active carbon filter.

Clean the fan and other surfaces of the cooker hood regularly using a cloth moistened with denatured alcohol or non abrasive liquid detergent.

WARNING: unplug the appliance or switch off the circuit breaker before carrying out maintenance operations.

3.2. METAL ANTI-GREASE FILTERS (Fig. 4 Ⓜ)

The metal anti-grease filters capture the grease particles of the vapours that develop during cooking, therefore they are subject to clogging according to the frequency of the use of the appliance.

In order to prevent fire hazard, it is recommendable to clean the filter every 2 months by carrying out the following instructions:

• Remove the filters from the cooker hood and wash them in a solution of water and neutral liquid detergent, leaving to soak.
• Rinse thoroughly with warm water and leave to dry. The filters may also be washed in a dishwasher. The aluminium panels may alter in colour after several washes. This is not cause for customer complaint nor replacement of panels.

3.3. ACTIVATED CARBON FILTERS (Fig. 4 Ⓛ)

only for re-circulating version (sold separately)

The activated carbon filters purify the kitchen vapours, the air is then conveyed back into the kitchen. The saturation of the active carbon filter depends on the frequency of use of the appliance, by the type of cooking and the regularity of cleaning the anti-grease filters.

The filters are not washable nor re-useable and must be replaced at maximum every four months.

3.4. CLEANING

Clean the fan and other surfaces of the cooker hood regularly using a cloth moistened with denatured alcohol or non abrasive liquid detergent.

4. SAFETY PRECAUTIONS

Take care when the cooker hood is operating simultaneously with an open fireplace or burner that depend on the air in the environment and are supplied by other than electrical energy, as the cooker hood removes the air from the environment which a burner or fireplace need for combustion. The negative pressure in the environment must not exceed 4 Pa (4 x 10 -5 bar).

Provide adequate ventilation in the environment for a safe operation of the cooker hood.

Follow the local laws applicable for external air evacuation.

4.2 WARNING!!

In certain circumstances electrical appliances may be a danger hazard.

A. Do not check the status of the filters while the cooker hood is operating
B. Do not touch the light bulbs after appliance use

C. Flambè cooking is prohibited underneath the cooker hood
D. Avoid free flame, as it is damaging for the filters and a fire hazard
E. Constantly check food frying to avoid that the overheated oil may become a fire hazard
F. Disconnect the electrical plug prior to any maintenance.

DISPOSAL OF OLD ELECTRICAL APPLIANCES

The European Directive 2002/96/EC on Waste Electrical and Electronic Equipment (WEEE), requires that old household electrical appliances must not be disposed of in the normal unsorted municipal waste

stream. Old appliances must be collected separately in order to optimise the recovery and recycling of the materials they contain and reduce the impact on human health and the environment.

The crossed-out dustbin symbol on the product reminds you of your obligation regarding separated waste collection. Consumers should contact their local public service or their local dealer for more information on the correct disposal of exhausted household appliances.
