Q: What type of external exhaust pipe should be used for this ROSIERES RHC 224 IN hood?

This ROSIERES RHC 224 IN hood has two operating modes : an external exhaust (outward) or internal recirculation with an optional charcoal filter. For external exhaust operation, here’s what you need to know: Pipe diameter : The pipe must match the connection connector of the hood. Check the diameter of the connector on your model before purchasing the pipe. Length : Use a pipe of strictly necessary length according to the official manual. Excessive length reduces suction efficiency. Bends and routes : Minimize the number of bends. You can use 90-degree bends, but limit their number to avoid losing suction power. Material : Generally, exhaust pipes for range hoods are made of flexible or rigid aluminum. Prefer an aluminum pipe for its durability. For installation, ensure that the pipe is securely attached to the connector and leads outside. Never install the hood without a properly placed grease filter.

Question 2

Where are the activated charcoal filters located on the ROSIERES RBS93IN hood?

Accepted Answer

On the ROSIERES RBS93IN hood, the activated charcoal filters are located inside the hood, in the central position, directly behind the metal grease filters. They are part of the filtration system in recycling mode and are provided with the hood (reference FCH260, sold in packs of 2).

Precise location: Once the grease filters are removed, you will access a specific housing where the two charcoal filters are clipped in. They are positioned to purify the air that will then be returned to the kitchen in filtering mode.

Accessing the filters:

Turn off and unplug the hood to ensure your safety before any handling.
Remove the metal grease filters by unclipping them or sliding them down, according to Fig.6 of the manual (these filters are washable and should be washed at least every 2 months).
Once these filters are removed, you will easily access the charcoal filters that are clipped into their specific housing inside the hood.
Unclip or remove the two charcoal filters to replace them.

Replacement and maintenance: The activated charcoal filters are neither washable nor regenerable. They must be changed every 4 months at a minimum (saturation depends on your usage frequency and type of cooking). The device will signal when it is time to replace them: the display C flashes alternating the operating speed and the letter A (e.g., "1 and A"). After installing the new filters, perform a reset by pressing the A button for 5 seconds until the flashing stops.

These charcoal filters are essential for absorbing cooking odors in recycling mode (filtering mode). Regular replacement ensures optimal efficiency and better air quality in your kitchen.
