Accessories for IVAR.2.0 air conditioners – complete overview of parts and their functions

When a customer chooses an IVAR.2.0 air conditioner, they usually have the main indoor and outdoor unit in mind – and that is perfectly understandable. Accessories, however, are just as important a part of the whole system, and experienced installers know where to save effort and where neglect will cause problems a few seasons later. This article focuses on specific parts and kits available for the IVAR.2.0 series, explains how each part works, why it is important, and in which situations you really need it for a real customer project.

The IVAR.2.0 series is among the popular professional solutions for apartment buildings, administrative spaces, and commercial premises. Its advantage is a reasonable price, reliable operation, and availability of spare parts directly from the distributor. The availability of accessories is an argument that plays a key role in contract installation – no one wants to wait three weeks for a cover or a mesh when the outdoor unit is already on the scaffolding.

Why accessories are just as important as the unit itself

From a technician's point of view, an air conditioner is only as good as it is protected. The outdoor unit is exposed to weather conditions all year round – rain, snow, insects, leaves, and wind brings foreign material into it. In summer, wasps and cockroaches looking for warmth can enter it. The indoor unit, on the other hand, must have a clean cover, as aesthetics play a role especially in living rooms and company reception areas. Each of these problems has a solution in the form of the right accessories.

In professional installations, accessories are ordered together with the unit, not as an afterthought. The reason is simple: installation is done at once, the scaffolding or platform is on site only once, and adding protection later means another visit and additional costs. If you are also looking at other topics in our Knowledge Center, for example the article "Air conditioner installation step by step – installation process and requirements", you will find there a recommendation to include accessories in the project from the beginning.

Bottom cover for IVAR.2.0 – what it is and why the original plastic is not enough

The bottom cover of the outdoor unit is a part that is easily forgotten when planning the installation. The outdoor unit of the air conditioner is designed in such a way that it drains condensation and at the same time draws air from the lower part. Without the right cover, this area is prone to dirt, mechanical damage, and also an aesthetic problem – the exposed bottom parts of the plastic cover look quite worn after a few months outside.

Bottom cover for IVAR.2.0 is a replacement or additional part intended for standard sizes of the outdoor unit of this series. The manufacturer supplies it in the same color as the basic unit, so the result looks like part of the original design, not an afterthought patch.

When you need to replace or add a bottom cover

In practice, you will encounter the bottom cover in several typical scenarios:

After damage during transport or installation – the outdoor unit is moved during installation, and the bottom part of the cover is mechanically the most vulnerable. A small crack can lead to further cracking due to frost.
After a winter with heavy snow or ice – ice forming on the bottom sheet of the unit can mechanically lift the plastic cover when it melts, causing it to crack or break off.
During service replacement after several years of operation – UV radiation ages the plastic, especially on south-facing facades. The original cover may be brittle and have a faded color.
During installation reconstruction – when the customer takes over a building with an existing air conditioner and wants to bring the unit back to its original condition.

Bottom cover for IVAR.2.0 9HP MINI – smaller format with the same function

The IVAR.2.0 series includes not only standard sizes but also a compact version marked as 9HP MINI. This unit is physically smaller, and therefore requires its own cover adapted to its dimensions. Bottom cover IVAR.2.0 9HP MINI is therefore a separate part that cannot be interchanged with the bottom cover for larger models – this is important to remember when ordering, so you do not receive a part that does not fit.

The 9HP MINI version is popular for smaller spaces – offices, hotel rooms, small apartments, and also technical rooms, where you need air conditioning without a massive outdoor unit. Precisely in smaller buildings and apartment houses, where the unit is hanging on the facade and is clearly visible, the condition of the cover is more visually noticeable. Cracked or missing bottom covers on 9HP MINI look much more "cheap" than on a larger industrial unit hidden under the roof.

How to distinguish the correct cover size when ordering

When ordering accessories for IVAR.2.0, always check the type plate of the outdoor unit. The power rating in HP (horsepower) and the MINI designation will clearly tell you which cover you need. If you do not have access to the plate, simply measure the width of the bottom edge of the outdoor unit – the manufacturer specifies the cover dimensions for each model, and these data can be found in the technical documentation.

From practice, I know that the most common mistake when ordering occurs when the installer sends the customer to order a "replacement cover for the IVAR air conditioner" without specifying the model. The customer orders a standard cover, but the unit is MINI – and the cover does not fit. The result is another visit and loss of time. Therefore: always the model, always the type designation.

Rain protection kit for IVAR.2.0 air conditioners – protection that every façade will appreciate

The outdoor unit of an air conditioner is designed to withstand normal rain. This, however, does not mean it is without issues when exposed to continuous direct wetting, splashing water from a roof, or rain – certain parts of the cover are constantly exposed to water pressure coming from the side. Precisely in installations on a façade without an overhanging roof or on a balcony, where water runs down the wall directly onto the unit, long-term wetting becomes a problem.

Rain protection kit for IVAR.2.0 air conditioners is specially designed accessory that forms a roof or protective panel above the outdoor unit. It prevents direct impact of raindrops on the electronics, fan blades, and air intake openings. It is not just about aesthetics – wet electronics age faster, fan motors corrode after repeated wetting, and the overall lifespan of the unit is shortened.

Where rain protection is most important

From the installer's perspective, there are locations where the rain protection kit is almost mandatory:

Façades without a canopy or awning – the unit is directly exposed to precipitation from above and from the sides in strong winds.
Rooftops and terraces – on horizontal surfaces, water accumulates and can pool around the unit's base for hours after rain.
Northern and northwest façades – here, the casing is less illuminated, humidity remains longer, and moss and algae form on the surfaces.
Installations in mountainous areas – higher intensity of precipitation and longer periods of humid weather.
Industrial zones with chemical emissions – acid rain accelerates the corrosion of steel parts of the outdoor unit.

In one project at an apartment building in Banská Bystrica, I saw three outdoor units without protection installed on the northern façade. After four years of operation, two of them were in good condition because they were protected by the balcony overhang above them. The third one, without any protection, had a rusted fan, cracked lower plastic parts, and a shortened cable due to repeated wetting of the power block. The repair cost significantly exceeded the price of the rain protection kit.

The topic of protecting the outdoor unit from rain and pests is discussed in more detail in the article "Protection of the outdoor unit from rain and pests – why and how to do it," where you will find a more detailed analysis of damage mechanisms and practical tips for different types of installations.

BUG PROTECTION KIT FOR IVAR.2.0 AIR CONDITIONERS – A PROBLEM THAT IS OFTEN OVERLOOKED

Insects in air conditioners are a topic that is discussed less than performance or energy efficiency, yet in practice it is a real problem with real consequences. The BUG PROTECTION KIT FOR IVAR.2.0 AIR CONDITIONERS consists of fine mesh screens and protective covers that prevent insects from entering the outdoor unit through ventilation openings and spaces around pipe penetrations.

Which insects are problematic and why

The most common ones are wasps and moths. The outdoor unit is an ideal place for them to build nests – it is protected, warm in winter (residual heat from the compressor), and sufficiently ventilated. A wasp nest can mechanically block the fan, clog the heat exchanger, and cause a malfunction that requires a service intervention. In addition to wasps, the following are also problematic:

Pest beetles – in warmer areas or in restaurants and supply yards, where organic waste is nearby. Pest beetles chew through cable insulation.
Ants – they seek warmth and are attracted to the electromagnetic field of the compressor. Ants in electronics can cause short circuits.
Cockroaches and rodents – they hibernate in cavities, their droppings contain acids that damage printed circuits and contacts.
Spiders – their webs on the intake heat exchanger reduce air flow and lower the efficiency of the unit.

How the bug protection kit works in practice

The kit is designed so that it does not interfere with air flow, which is a key point – a too dense mesh would increase the resistance of the air being drawn in and reduce the unit's performance. The mesh material is resistant to UV radiation and weather conditions, so it does not fade or become brittle after a few seasons. Installation is simple and can usually be done by an installer without special tools within a few minutes directly during the installation of the outdoor unit.

From practice: at a catering facility in Bratislava, we found after the first season of operation that the indoor unit had stopped cooling at full capacity. The service technician discovered a wasp nest in the lower left corner of the outdoor unit, which partially blocked the finned heat exchanger. Cleaning and disinfection cost the customer more than the bug protection kit would have cost at the time of installation. Since then, we have been automatically including the bug protection kit in every quotation for catering businesses.

For more information on prevention and troubleshooting related to biological contamination, see the article "Common air conditioner faults and how to recognize them."

Complete protection of the outdoor unit – combination of accessories

In practice, accessories are not combined randomly – there is a logical sequence of how individual parts work together. An ideal configuration of the IVAR.2.0 outdoor unit for standard wall mounting looks like this:

Bottom cover – protects the lower edge from mechanical damage and dirt
Rain protection kit – diverts rainwater from the top and front part of the unit
Bug protection kit – prevents insects from entering through ventilation openings and gaps

These three elements do not overlap or interfere with each other – each addresses a different type of threat. The combination of all three is the most cost-effective way to extend the life of the outdoor unit by several years and reduce the likelihood of an unplanned service intervention at an inconvenient time (for example, in the middle of a hot summer when service capacities are fully booked).

Accessories and warranty conditions – what to pay attention to

One aspect that customers often overlook: the installation of approved original accessories may be a condition for maintaining the device warranty. Air conditioner manufacturers, including the IVAR.2.0 series, specify which accessories and which work procedures are in line with warranty conditions. The use of non-original spare parts or improvised protective elements can cause problems during a claim.

From a practical point of view, this means: when installing a bottom cover or a bug protection kit, use parts intended for the specific model. Not generic mesh from the hobby market, not plastic covers from another series of equipment. Original parts are designed so that they do not change the flow characteristics, do not dampen vibrations in a different way than intended, and do not cover ventilation openings through which condensate must be drained.

Planned maintenance and inspection of accessories

Accessories are not a one-time purchase forgotten after installation. Regular inspection of the condition of covers and meshes should be part of the annual service inspection. The recommended procedure for the annual inspection of the outdoor unit is as follows:

Visual inspection of the bottom cover – cracks, broken parts, loose fasteners
Inspection of the rain protection kit – deformations from snow or ice, loose screws, corrosion spots
Inspection of the bug protection meshes – clogging, damage from insects (wasps can modify the mesh from the inside), UV degradation of plastic
Cleaning of the meshes with a soft brush or compressed air – not high-pressure water, which can push dirt deeper into the fins
Inspection of the sealing around pipe penetrations – that is also where insects and water can enter

The article "Maintenance and service of air conditioners – what to do regularly and what to leave to the professionals" describes the entire procedure for the annual inspection, including cleaning the filter of the indoor unit and checking the refrigerant circuit.

Accessories for multisplit systems

If you operate a multisplit installation with one outdoor unit and multiple indoor units, the same rules for outdoor unit accessories apply. One outdoor multisplit unit is responsible for the failure of the entire system in case of a malfunction – this is why its protection is even more important than in split systems, where the failure of one outdoor unit affects only one room.

The topic of the difference between split and multisplit solutions is covered in the article Split vs. multisplit air conditioning – which is more cost-effective, where you will also find an economic comparison of operating and service costs.

Economics of accessories – is it worth it?

Let’s look at real-world numbers. The rain protection set and the insect protection set for IVAR.2.0 are affordable accessories that represent only a fraction of the cost of the entire air conditioning system. A service intervention due to a malfunction of the outdoor unit caused by an insect nest or corrosion from long-term exposure to moisture costs several times more – not to mention the cost of materials and possible replacement parts.

When calculating the return on investment in accessories, the question is not "Is it worth it?" but rather "Why do some installers still skip it?" The answer is simple: pressure on the offer price. The customer compares offers based on total cost, and if no one explains what is included in the accessories and why they are important, they will choose the cheaper option without them. This is a mistake they will pay for later – and not just once.

Therefore, in every professional installation, we recommend explaining the function of each accessory to the customer and including it in the offer with a clear description. A customer who understands why they are paying will pay more willingly than one who has an item quietly added to their invoice.

Accessories and the combination of air conditioning with heating

The IVAR.2.0 series air conditioners are reversible – they function as coolers in summer and as air-to-air heat pumps in winter. This means that the outdoor unit operates in winter as well, when the external conditions are different from those in summer. Frost on the heat exchanger, snow load on the top cover, and ice formed during defrosting – these are all situations that the rain protection set and the bottom cover must account for.

Good news: the accessories for IVAR.2.0 are designed with year-round operation in mind. The rain protection set is dimensioned so that it does not create a surface for snow to accumulate, and the bottom cover respects the need for condensate drainage during the heat exchanger defrosting. If you use the IVAR.2.0 air conditioner as part of a hybrid heating system (in combination with a boiler or floor heating), do not forget that the winter load on the accessories is higher and annual inspection is all the more important.

We write more about the combination of air conditioning with heating in the article Air Conditioning in Professional Heating – Combining with Heat Pumps and Heating.

Most frequently asked questions (FAQ)

Do I have to buy accessories for IVAR.2.0 separately, or are they part of the unit delivery?

The standard delivery of the IVAR.2.0 outdoor unit includes the basic components necessary for operation, but protective accessories such as the rain protection set, the insect protection set, or replacement bottom covers are ordered separately. This is intentional – not every location or type of installation requires the same protection configuration. When ordering the unit, always check the packaging and compare the contents with the technical specifications to know what you need to buy additionally.

Can I use the bottom cover from an older IVAR series on the IVAR.2.0 model?

This is not recommended. The IVAR.2.0 series has modified dimensions and cover profile compared to previous generations. A cover from the older series may not fit properly, may create gaps through which water and insects can enter, and may also disrupt condensate flow. Always use parts specifically designed for IVAR.2.0 or IVAR.2.0 9HP MINI according to the model of your unit.

Is the insect protection set effective against birds and rodents?

The set is primarily designed for insects – the mesh size is fine enough to keep out wasps, ants, beetles, and similar insects, but it is not dimensioned for mechanical resistance against birds or rodents. In installations in areas with a high presence of pigeons or rodents, it is necessary to supplement the protection with special mechanical barriers (steel mesh with greater strength), which are not part of the standard set. If you have this issue, consult your installer for an appropriate additional solution.

What is the installation procedure for the rain protection set – do I need a professional?

The installation of the rain protection set for IVAR.2.0 is relatively simple and is usually handled by an experienced installer without the need for professional certification. The set is attached to the outdoor unit using screws into existing holes or mounting rails. It is important to follow the manufacturer’s instructions – improper installation of the cover can redirect water to unprotected parts of the unit or hinder proper condensate drainage. If you are not skilled in installation and are unsure, leave it to the installation company during the annual inspection.

When is the best time to perform an inspection and replacement of accessories?

Ideally in spring, after the end of the winter season, before starting the summer operation. At that time, the outdoor unit is most accessible, and winter damage from ice, snow, or frost can be easily detected. Another suitable opportunity is in autumn before winter – then you can check the accessories before the heat pump’s winter operation. We recommend at least one inspection per year, and twice a year for exposed locations (mountain areas, coastal regions, industrial zones).

Does the insect protection set reduce the performance of the air conditioner?

A properly designed insect protection set for IVAR.2.0 has no measurable impact on the performance of the air conditioner during normal operation. The mesh size is large enough not to restrict airflow when the fan is running. Problems arise when the mesh is dirty – covered in dust, spider webs, or other dirt. Therefore, cleaning the mesh is part of the annual inspection. A neglected and dirty mesh can increase suction resistance and slightly reduce the system’s COP.

Conclusion – accessories as part of a long-term strategy

Accessories for IVAR.2.0 air conditioners are not just an added-on sale to the main product. They are a set of technically justified components that address specific problems in real installations under real conditions. Bottom covers protect the most vulnerable part of the outdoor unit, the rain protection set extends the life of the electronics and moving parts, and the insect protection set prevents biological contamination, which is expensive to remove and even more expensive if it causes a compressor failure.

We recommend designing a complete configuration of outdoor unit protection for every project and briefly explaining to the customer why each part is where it is and what it does. A customer who understands this will not remove the accessories from the price offer and will later return to service satisfied – because their unit runs without problems for five, seven, or even ten years.

If you are unsure which accessory model is correct for your specific unit, look at the type plate on the outdoor unit, check the model designation and HP, and order accordingly. In case of doubt, contact our team – we will advise you to get the right part on the first try.
