Performance and range of use

For the Mitsubishi Electric MXZ-2F53VF outdoor unit, cooling capacity of 5.3 kW and heating capacity of 6.4 kW are stated, adjustable from 1.1 to 5.6 kW and 1.0 to 7.0 kW, respectively. The MSZ-AY35VGK indoor unit is stated with 3.5 kW cooling and 4.0 kW heating capacity, the MSZ-AY25VGK indoor unit with 2.5 kW cooling and 3.2 kW heating capacity. The total capacity of the indoor units is 6.0 kW, which is 0.7 kW above the capacity of the outdoor unit. The operating range is stated as minus 10 to plus 46 °C outdoor temperature for cooling and minus 15 to plus 24 °C for heating. Both connections on the outdoor unit are stated as 6 mm on the liquid side and 10 mm on the gas side.

The stated areas of approximately 27 to 35 m² for the larger and approximately 19 to 25 m²^* for the smaller indoor unit are guidelines for typical room height and standard insulation, not a binding design. Decisive factors are room height, insulation, window areas and shading, as well as the number of people and devices in the room. We can check upon request whether the allocation to your two rooms is suitable.

* Guideline based on the cooling capacity stated by the manufacturer, with typical room height of approximately 2.5 m, standard insulation and average solar radiation. Different conditions on site, such as large window areas, sloped roofs or a high number of people, may require a different performance class. The binding design is carried out on an object-specific basis. For a professional design of your property, please contact us.

What do A+++ and SEER 8.63 mean for this set?

On the A+++ to D scale, A+++ is at the very top; this class in cooling requires a SEER of at least 8.5, the set is stated with 8.63. In heating, A++ applies, for which the SCOP must reach at least 4.6; 4.60 is stated, so exactly this value. For the outdoor unit, 1.4 kW power consumption in cooling and 1.56 kW in heating are stated in the manufacturer data.

Can I control the system via app?

Yes. Both indoor units, MSZ-AY35VGK and MSZ-AY25VGK, carry the K suffix and thus have the WiFi module already on board from the factory, an add-on module is not required. Which app the manufacturer provides for this is not stated on this page; we will give you the name upon request. For operation on site, each indoor unit comes with an infrared remote control with a weekly program.

How do two indoor units work with one outdoor unit?

The MXZ-2F53VF outdoor unit has two connections, each with an indoor unit with its own refrigerant line. Both rooms are set independently, with the respective remote control or in the app, while cooling and heating capacity come from the one outdoor unit.

Is the outdoor unit sufficient for both rooms at the same time?

The two indoor units are stated together with 6.0 kW, the outdoor unit with 5.3 kW; the difference is 0.7 kW. If both rooms run at full load at the same time, each indoor unit gets just under nine tenths of its rated capacity. The outdoor unit regulates continuously from 1.1 kW upwards and does not cycle at low load. Two rooms used simultaneously, one larger and one smaller, are exactly what this set is assembled for.

For which rooms is this set suitable?

The indoor unit with 3.5 kW is designed for approximately 27 to 35 m² according to the manufacturer, the one with 2.5 kW for approximately 19 to 25 m²^*: living room and bedroom, practice room and office, a large and a small hotel room. Both units are stated with 18 dB(A) on the lowest speed and have the same housing. We carry out the binding design on an object-specific basis.

How many indoor units are included in the scope of delivery?

Two: one MSZ-AY35VGK with 3.5 kW and one MSZ-AY25VGK with 2.5 kW, plus two infrared remote controls and the MXZ-2F53VF outdoor unit. Pipes, mounting material and a bracket for the outdoor unit are not included in the scope of delivery.

Is a mounting set required for each indoor unit?

Yes, two, and they are the same, although the indoor units have different capacities: 6 mm (1/4") on the liquid side and 10 mm (3/8") on the gas side at both connections. The material is not part of the offer, the specialist company selects it for the installation situation.

How large and how heavy are the units?

Both indoor units have the same housing with 798 x 299 x 245 mm and 10.5 kg, the capacity difference is not visible from the outside. The outdoor unit measures 800 x 550 x 285 mm and 37 kg; whether the wall can support a bracket for it is clarified by the specialist company during the inspection.

How loud is the system?

Both indoor units are stated with 18 dB(A) on the low and 36 dB(A) on the high fan speed, regardless of their capacity. The outdoor unit is stated with 46 dB(A) in cooling and 51 dB(A) in heating operation. The page does not provide information on the sound power level. For the night, there is a night mode with reduced fan speed and capacity.

What filters does the indoor unit have?

Both indoor units are equipped with an air purification filter with silver ion coating and an integrated V-Blocking filter according to the manufacturer. A Quad Connect Plasma filter is mentioned as an accessory and is not part of the scope of delivery. The filters are cleaned or replaced as part of regular maintenance.

How far apart can the indoor and outdoor units be?

The permissible pipe length and the permissible height difference between the indoor and outdoor unit are not stated on this page; we will give you both values upon request. During planning, the location of the outdoor unit determines how long the two pipe routes will be.

Can I use the system for heating in winter?

Yes, the heating operation is specified for outdoor temperatures from minus 15 to plus 24 °C, and the cooling operation from minus 10 to plus 46 °C. For heating, it has an A++ rating on the A+++ to D scale, with a SCOP of 4.60. The heating capacity exceeds the cooling capacity: 6.4 kW at the outdoor unit, 4.0 kW at the larger indoor unit, and 3.2 kW at the smaller indoor unit. With i-save, a lower temperature can be saved and recalled at the touch of a button, for example at night or when you are away. We can check upon request whether the system is sufficient as the sole heat source.

Can I install the air conditioning system myself?

No, installation and commissioning must be carried out by a certified specialist company. Two separate cable routes to the two rooms, as well as a designated area or wall bracket for a 37 kg outdoor unit, need to be planned.
