What should I do if my hood is not sucking or it sucks a little?

First of all, you have to understand if the problem results from the hood itself or, as often happens, from an improper installation.


If the hood is in duct our mode, you have to disconnect the exhaust pipes from the hood, turn on the fan and check with a hand if the air comes out from the hood. If you feel that the air comes out, the problem must be solved by analyzing the installation (pipe too long and with too many bends, pipe with internal surfaces that are not smooth, obstructions inside the pipe, etc.). Connecting a hood to an exhaust pipe with a smaller diameter than the engine outlet significantly reduces suction. For example, the use of a 125mm exhaust pipe in a hood with a 150mm outlet leads to a reduction in performance of the order of 10/15%.


If the hood is in recirculation mode, you have to remove the charcoal filters, turn on the fan and check whether the suction is now satisfactory. Charcoal filters can reduce by 30-40% the performance of the hood.

My hood is too noisy

If the noise is mechanical, remove any pipe connected to the hood and check that anything dropped inside the motor that could comes into contact with the fan blades.

If the noise is not mechanical, disconnect, if present, the duct out pipes from the hood, turn on the fan and check if the situation improves. If it improves the problem can be solved by analyzing the installation. If the hood is in recirculation mode, remove the charcoal filters and see if the situation improves.

A louder noise is normal with charcoal filters installed.

What diameter should I use for the duct out pipes?

The performance of the hood is guaranteed using pipes with the same diameter of the motor output. Smaller pipes reduce appliances performance and contribute to increase the noise.

What kind of pipe should I use?

We recommend using a pipe with smooth internal surfaces. It is also good practice to minimize the number of bends and the length of the pipe.

How can I clean the hood?

To clean the hood, it is strictly recommended to use products with a neutral pH, warm water and non-abrasive sponge.

How often should I wash the metal grease filters?

The metal grease filters must be washed at least every month with hot water and detergent (in a dishwasher). The filters can become discolored after a few washes. This is normal and does not mean that they need to be replaced.

How often should I replace the charcoal filters?

If present (hood installed in recirculating mode), the charcoal filters must not be washed and should be replaced 2 or 3 times a year in accordance with the use of the hood.

My hood produces drops on the lower surface and on filters.

The condensation creates especially when the hood is installed above an induction hob. This is a physical phenomenon and it is not due to a bad functioning of the product. Unlike the gas hob, the induction heats only the pots with food and not the surrounding air, so the surfaces of the hood remain cool. When the hot cooking fumes rise, they meet the cold surfaces of the hood, and then releasing the moisture in the air that turns quickly into water droplets.

On my hood appeared evidence of oxidation / rust.

The presence of oxidation or rust cannot come from the corrosion of steel but from external objects or agents that affect the surface.

We recommend to clean the hood with cream cleansers suitable for steel by means of a soft damp cloth and wipe gently.

Some lights flash on my hood; do I call for service?

Most of Galvamet products are equipped with electronic controls that warn, by flashing the lights, the necessity to clean the metal grease filters or to replace any charcoal filters. These notices must be reset after their appearance or they will be present at any switch off of the product. To reset them, comply with the instructions manual.

At what distance can I install the hood from a gas hub?

The installation distance is indicated in the instructions manual of the product. Installing the hood at a lower distance voids the warranty and risks the user’s safety.

It is preferable a hood in recirculating or in duct out mode?

The duct out mode (with exhaust pipes) is more powerful and therefore should be preferred.

How do I turn a recirculating hood into duct out?

The recirculating hood can be turned into duct out by connecting the motor air outlet to an exhaust pipe and removing any charcoal filter installed in the hood.

Where do I find the product code and the manufacture week and year?

The product code and the manufacture week and year are written on the silver label attached on the inner wall of the product.
