Load calculation and documentation
Outdoor unit: MXZ-3F54VF. Check PCB and inspection.
For the exterior MXZ-3F54VF without suffix VF2/VF3/VF4 and these indoor units AY: 500 g additional for connecting 3 indoor units. For length: 0 g additional up to 50 m total, respecting 25 m per branch. Do not apply this rule to revisions VF2/VF3/VF4 or to other indoor units.
L is the sum of the outbound runs of all branches. Do not add the liquid and gas pipes separately. Connection diameters of the exterior, in liquid / gas order. Confirm the piping and adapters of each interior.
Data to prepare the installation, not an instruction for recharging due to a fault. The charge must be verified and carried out by a qualified installer according to the PCB, the inspection, and the equipment manual; do not add refrigerant solely due to a lack of cooling.

Questions about MXZ-3F54VF + 3 × MSZ-AY25VGK
How many frigories does this 3x1 air conditioning unit have?
It has a nominal capacity of 4,644 frigories/h (5.4 kW) for the entire unit. It is not 4,644 frigories for each room nor the free sum of the powers of the splits. The available capacity is distributed among the indoor units that are operating; it changes with demand and usage conditions.
Is it suitable for 3 rooms with a single outdoor unit?
Yes: the set includes 3 × MSZ-AY25VGK and one outdoor unit. There are 3 indoor climate control points. To determine if it covers the specific rooms, it is necessary to check the load of each one and the simultaneous demand against the 5.4 kW nominal of the set; counting rooms is not enough.
Does it fit if the living room needs to be cooler than the bedrooms?
This set includes splits of the same model. If one room heats up much more than the others, it is advisable to check if it needs a different split. If you need more cooling when using the rooms at the same time, compare the Mitsubishi Electric 3x1 MXZ-3F68VF + 3 × MSZ-AY25VGKIt maintains the same splits and goes from about 4,644 to 5,848 frigories/h for the whole unit. Tell us the dimensions of each room, where the sun hits the most, and which ones you will use at the same time. With that, we can guide you on the combination, without assuming that the living room always needs more power.
Can I add the cooling capacities of the splits to choose it?
No. In Mitsubishi Electric MXZ-3F54VF + 3 × MSZ-AY25VGK, the reference for the published shared capacity is 4,644 frigories/h (5.4 kW) nominal for the set. The class figure or the indoor model number does not directly correspond to the delivered frigories. Without the distribution table for the combination, an independent figure per room is not guaranteed.
What does MXZ-3F54VF + 3 × MSZ-AY25VGK include?
1 × MXZ-3F54VF (outdoor unit); 3 × MSZ-AY25VGK (wall-mounted indoor units); 3 × SH22Q (remote controls). The previous composition identifies the units and controls of this offer. The installation is contracted separately.
What measurements should I check before booking the equipment?
Interior MSZ-AY25VGK · height × width × depth: 299 × 798 × 245 mm. Exterior MXZ-3F54VF · height × width × depth: 710 × 840 × 330 mm. These are the dimensions of the indicated components, not the minimum installation space. Also allow for the clearances, connections, and maintenance access required by the manual.
Is Wi-Fi included or is an accessory required?
Integrated Wi-Fi in each indoor unit, with control via MELCloud. No additional adapter purchase is required. The remote control operates via infrared; the Wi-Fi is built into the unit.
What command does the equipment receive?
Include 3 remote controls, one for each indoor unit: 3 × SH22Q.
Can I heat just one room?
You can operate each of the 3 indoor units of this AY 25+25+25 with its remote control, without having to keep all of them on. They share the outdoor unit MXZ-3F54VF: they can work in cooling or heating mode, but cannot cool one room while another is heating. The available capacity depends on which units are running.
What is the distance from the rooms where I can place the MXZ-3F54VF?
For the exterior MXZ-3F54VF of this set, the manual allows for up to 25 m of indoor piping and 50 m when summing all branches. The maximum height differences are 15 m between the exterior and interior and 10 m between interiors. The actual length of the piping is measured, not the straight-line distance. The installer must check the diameters, adapters, bends, load, and equipment inspection: these limits are not installation meters included in the price.
