Tested and recommended
faq
Can the connection between the indoor and outdoor unit be separated?
No, PortaSplit is a split air conditioner where the indoor and outdoor unit are connected. However, the connection can be removed when the unit is not in use.
Can the hose be extended?
The hose cannot be extended. Before purchasing, make sure that the length of 2 m is sufficient for your application.
Why is PortaSplit more efficient and powerful than traditional mobile air conditioners?
PortaSplit is a mobile split air conditioning system consisting of an outdoor and indoor unit connected to a refrigerant line.
The two-part structure of PortaSplit means that there is no negative pressure in the interior. This means that the warm outside air is not sucked in and remains outside.
What is the difference between a split air conditioner and a typical mobile monoblock air conditioner?
Typically, a portable air conditioner is not powerful enough to cool the entire room because heat is removed via a large hose. This causes a drop in air pressure, drawing warm air from outside back into the home and causing uneven cooling.
These problems do not exist with a split air conditioner, which like PortaSplit consists of an outdoor and indoor unit. With PortaSplit, the heat is released via an external heat exchanger without discharging the air to the outside, ensuring better cooling performance without changing the air pressure.
In principle, split air conditioners are more efficient and more powerful than monobloc systems of conventional air conditioners.
Where and for which windows can I use PortaSplit?
PortaSplit requires a window or door that can be opened. The outdoor unit is placed outside and the indoor unit remains in the room to be cooled. The outdoor unit can either be placed on the floor without brackets (balcony, terrace) or attached to a window with brackets. A frame is included in the scope of delivery for standard windows that can be opened to the side. For French balcony and skylight applications, the “Unviersal bracket” can be purchased as a separate accessory.
How do I attach the frame to the window?
The normal window frame and the Universal frame are designed to be installed without tools and without damaging the building. This means that you can install the split air conditioner yourself without drilling. Installation takes just a few minutes, as we demonstrate in the installation videos.
Should the window be open?
The window should remain open and have a hole for the connection hose. However, this was developed to be particularly flat (2.7 cm) to keep the gap as small as possible. The included window lock prevents the window from being opened by the wind, for example. The so-called “Hot Air Stop” is included for an even better seal.
What happens to condensation?
A built-in condensation pump brings any condensation to the outdoor unit, where it can drain onto the facade with the supplied condensation.
Why is the PortaSplit air conditioner called a heat pump?
Split air conditioners are basically air-to-air heat pumps. Therefore, PortaSplit can also be used for efficient heating with a SCOP of 4.0.
Can air conditioning be used in rental apartments?
Many people ask themselves: Can I install air conditioning in my rented apartment Because the PortaSplit mobile split air conditioner can be installed without permanently changing the facade, without screwing or drilling, it is also suitable for rented apartments. After use, it can be easily removed.
Can PortaSplit be used while you sleep?
As many people complain about the noise level of conventional mobile air conditioners, PortaSplit has been equipped with a special silent mode. With a sound pressure level of only 39db(A), this is far below the level of comparable units and has been developed with a quiet and comfortable sleep in mind.
Can the device also be installed permanently?
A permanent installation is possible, but for safety reasons it must be carried out by a professional installer or specialist. This usually requires drilling to lay the electrical and cooling lines. If a wall breaks through, extreme caution must be taken to avoid damage.
What refrigerant is used and how environmentally friendly is it?
PortaSplit uses R32 with a capacity of 0.62 kg.
The CO2 equivalent or GWP of R32 over a 100-year period is 675. This means that 1 kg of R32 contributes 675 times as much to the greenhouse effect as 1 kg of CO2 within the first 100 years of release.
The release of 0.62 kg of R32 corresponds to the release of 0.42 kg of CO₂.
Can I leave the device on the cradle outside the window for a longer period of time?
The holder is designed to keep the outdoor unit in place for longer. It is recommended to check fastening screws and locks periodically. In heavy rain or wind, the outdoor unit should be removed as long as the window can be closed safely.
Who can I contact if I have problems with the device?
To the seller or directly to Klimabrands A/S
Saltebakken 29, 9900 Frederikshavn, Denmark.
Phone: (+45) 77 34 33 33 30

What needs to be taken into account when setting up PortaSplit?
The indoor unit should be placed on a flat surface with sufficient distance from the wall to ensure optimal ventilation.
When mounting the outdoor unit, make sure that the bracket is properly locked to the window and that the feet are set in the correct position so that the outdoor unit is roughly level. It should not be too close to the window.
Do you need special tools to assemble PortaSplit?
No, you only need scissors or a carpet knife to attach the window gasket.
Can PortaSplit be assembled and disassembled as often as needed to flexibly cool different rooms?
Yes, setting up and dismantling the mobile split air conditioner only takes a few minutes, as we demonstrate in the various installation videos.
Up to what maximum outdoor temperature can PortaSplit cool effectively?
45°C (upper operating limit).
Up to what minimum outdoor temperature can PortaSplit heat efficiently?
-10°C (lower operating limit).
How can I make settings on PortaSplit or operate the device?
There are 3 different options to create flexible settings:
1. Through the touch panel on the indoor unit
2. Using the included remote control
3. Through the SmartHome app
How do I dispose of PortaSplit after its lifetime?
The PortaSplit must be taken to an official collection point for the recycling of electrical appliances. The PortaSplit bears the classification symbol for waste electrical and electronic equipment (WEEE Directive).
What is included?
The following parts are included: PortaSplit (consisting of 2 parts, connected by a tube), zip guide, operating instructions, remote control, window lock, window holder, condensate drain kit, window gasket including Velcro tape, protective plate, steel safety rope including eye, rubber wheel stop, shorter support legs, refrigerant hose insulation, window sealing foam, HEPA filter (depending on country).
How many square meters is the system recommended for?
The MMCS-12HRN8-QRDO unit has a cooling/heating capacity of 3.5 kW. Depending on the location, rooms of up to 42m²/105m³ can be covered with the mobile air conditioner.
How is PortaSplit electrically connected?
With a standard household socket.
Can the system be operated with an app?
PortaSplit can of course be operated via an app. This is available free of charge for Android and IOS in the respective store (SmartHome).
Is there a minimum distance to neighbors due to the noise from the outdoor unit?
PortaSplit is a mobile and silent air conditioner that can be set up as needed (e.g. on the balcony or by the window, etc.). If anyone ever complains that it’s too loud, it can be moved to another location immediately.
Nevertheless, you should not set up the outdoor unit directly next to your neighbor’s window at night, you should pay attention to the placement here, especially for resting at night.
