Vaillant aroVAIR VA 1-AF CS - mounting legs for slim fan coils

Product detailed description

Vaillant aroVAIR VA 1-AF CS is an original set of mounting legs for slim console (convector) fan coil units of the Vaillant aroVAIR pro CSN series, enabling free-standing vertical installation of the unit directly on the floor. CSN console units are structurally prepared for two ways of mounting - either recessed into a prepared building niche (where legs are not needed), or free-standing on the floor against a wall, where this set of legs is an essential accessory for stable and aesthetically clean anchoring of the unit.

What the legs are for

When you need the legs

Thanks to their low profile (12.6 cm), CSN console units have three basic installation methods: recessing into a prepared building niche or recess (where the unit "fits" into the wall and legs are not needed), horizontal mounting suspended under the ceiling (also without the need for legs), or free-standing vertical installation directly on the floor against a wall - and it is precisely for this third installation method that the VA 1-AF CS mounting legs are an essential accessory. If your project does not have a structurally prepared niche for recessed installation and you neither want nor can suspend the unit under the ceiling, this set of legs is the only way to place the unit stably and safely on the floor.

Advantages of floor installation on legs

Free-standing floor installation on legs is the simplest and fastest way to install a console fan coil - unlike recessed installation into a niche, it requires no building work on the wall structure, which is especially advantageous for additional installation into an already finished, occupied interior or during renovations, where it is undesirable or not possible to interfere with load-bearing or partition structures. A unit on legs is also, if needed, more easily relocated or removed (for example when the room layout changes in the future, or during a service intervention requiring access to the back of the casing).

Installation

The legs are mounted to the underside of the fan coil's casing using the supplied mounting material, after which the unit is placed on a level floor surface near a wall (for the hydraulic and electrical connection). It is recommended to additionally secure the unit against tipping over despite the legs, by simply fixing it to the wall (for example with a short bracket or strap on the upper part of the casing), especially in households with small children or pets. The exact installation procedure and the tools needed can be found in the installation manual supplied with the unit, or we recommend entrusting the installation to an experienced installer.

Compatibility

The VA 1-AF CS set is intended for slim console (convector) units of the Vaillant aroVAIR pro CSN series, specifically the models VA 1-015 CSN and VA 1-025 CSN, which are also part of our e-shop's offering. Since both models share the same casing height and depth (differing only in width), this set of legs is compatible with both models without needing to distinguish the variant when ordering.

Why choose original accessories

Although it would theoretically be possible to improvise substitute stands or legs from another manufacturer, the original set from the unit manufacturer guarantees precise dimensional and mechanical adaptation to the given fan coil model - the correct height (ensuring free air circulation under the unit, which is important for correct function of air intake from below, if the unit is designed this way), stability corresponding to the unit's weight, and aesthetic consistency with the design of the whole appliance. Using a non-original or improvised solution can compromise these parameters and, in extreme cases, even invalidate the manufacturer's warranty.

Maintenance

The mounting legs require no special maintenance; it is only recommended to occasionally check the tightness of the fixing screws, especially if the unit is placed in a space with heavier foot traffic or is occasionally relocated.

Frequently asked questions

Summary - why choose the VA 1-AF CS

The Vaillant VA 1-AF CS mounting legs are an essential accessory for anyone who chooses free-standing floor installation of a console CSN fan coil without building work on the wall. They are a simple, fast and aesthetically clean alternative to recessed installation, particularly suitable for additional installation into an already finished interior.

Even a small accessory such as mounting legs can affect the overall impression of the interior and long-term satisfaction with the installation - we therefore recommend not underestimating the choice of original, precisely adapted accessories over an improvised solution, which could compromise the stability, functionality, or aesthetics of the entire installation.

Planning the installation in advance

When designing a new build or renovation, we recommend making the decision between recessed installation into a niche and free-standing installation on legs as early as possible - for recessed installation, a building recess of the correct dimensions needs to be prepared already during the shell construction phase, whereas installation on legs is more flexible and can be finalised later, or changed afterwards. This flexibility is one of the main reasons why many developers choose the leg variant instead of a permanent building solution, which is difficult to change afterwards.

When ordering, we also recommend considering adding the Vaillant VA 1-A3WV CS 3-way switching valve set, if your installation requires automatic switching between heating and cooling mode on a shared hydraulic distribution system.

Typical deployment scenario

Imagine the renovation of a flat in an older apartment building, where the developer is replacing the original high-temperature heating with a heat pump and console fan coils. Since this is an already finished, occupied interior, it is not realistic to prepare a building recess (niche) in the wall for recessed fan coil installation - this would require demolition work, which is neither practical nor desirable in an occupied flat. In this case, free-standing installation on VA 1-AF CS legs is the fastest and least invasive solution - the unit is simply placed on the floor against the wall, connected to the hydraulic distribution system (which can also be run on the wall surface in trunking if it is not possible to interfere with the wall's core) and is ready for operation without any demolition work.

The same scenario also applies to commercial premises with a short implementation deadline, where there is neither time nor room for building modifications before installing the heating and cooling system.

Relationship to other components of the aroVAIR CSN system

The VA 1-AF CS mounting legs complement the accessory range for slim console fan coils together with the Vaillant VA 1-A3WV CS 3-way switching valve set, which addresses the opposite, hydraulic side of the installation (automatic switching between heating and cooling mode). While the legs address the question of "how to physically place the unit on the floor", the valve addresses the question of "how to ensure correct unit function in both operating modes". When fully equipping a new console fan coil installation, we recommend considering both accessories together if your specific situation (free-standing installation plus a shared two-pipe distribution system) requires both.

Aesthetic aspect of floor installation

Well-made mounting legs are not only a functional but also an aesthetic element - a correctly sized leg height ensures that the unit does not look "placed" directly on the floor, but visually slightly raised, which looks neater and, at the same time (in some fan coil designs where part of the air is drawn in from below), also ensures the necessary free air circulation under the unit's casing. The colour and material finish of the legs is matched to the overall design of the unit, so they look like part of the product, not like an additionally added, visually distracting element.

Ordering and project planning

When planning a console fan coil installation, we recommend deciding on the mounting method (recessed into a niche, ceiling-suspended, or free-standing on legs) as early as possible, ideally before finalising the layout of the electrical and hydraulic distribution in the given room. For free-standing installation on legs, you need to account for the exact position of the unit against the wall, to which the supply and return pipes for heating/cooling water then need to be led, as well as possibly an electrical connection for power supply and connection to any wired accessories. Our sales team will be happy to advise on choosing the right combination of accessories (legs, switching valve) for your specific project - do not hesitate to contact us before your final order if you are not sure of the exact configuration of your space.

Summary of technical advantages

• Enables installation without any interference with the wall's building structure - especially suitable for renovations of occupied spaces.
• Faster and cheaper installation compared to recessed installation into a building niche.
• Flexibility - the unit can be more easily relocated or removed in the future.
• Dimensionally and mechanically precisely adapted to the given fan coil model, unlike improvised solutions.
• Preservation of aesthetic consistency with the design of the whole unit.

Comparison of console fan coil mounting methods

The comparison shows that each mounting method has its place depending on the specific situation - recessed installation is the most elegant but requires planning from the start of construction; ceiling-suspended mounting frees up the floor but requires a suitable ceiling structure; free-standing installation on legs is the most universal and quickest to implement, which is why it is the most common choice for renovations and additional installations.

When deciding between the individual mounting methods, we recommend considering not only the current situation but also possible future changes in the room - if you plan to change the furniture layout or the room's disposition in the future, free-standing installation on legs offers the greatest flexibility, since the unit can be relatively easily disconnected and relocated without permanent interference with the building structure.
