Over a century of history at the service of technology Mitsubishi Heavy Industries Ltd is the founder of the Mitsubishi Group, one of the major industrial and financial empires in the world, with a network of as many as 131 industries. The origin of the brand dates back to the last decade of the nineteenthcentury in Nagasaki, where the first big shipyard was established to produce ships for the Japanese navy. Shipbuilding is still one of the most important sectors for Mitsubishi Heavy Industries.

Technological evolution The Mitsubishi Heavy Industries research laboratories have always put the study and application of new technologies at the forefront, to support the product development of the highest quality, respecting the environment and creating airconditioned solutions.
Total wellbeing Ideal climatic conditions every month of the year; functional and detailed design; air quality; silent running and maximum energy saving. These are the features that Mitsubishi Heavy Industries offers for the desired wellbeing. All products of the range have filtering and air purifying systems that can clean the air in the room to prevent allergies and respiratory diseases, contrasting and completely destroying the formation of bacteria and mould.
KX4/KXR4 The VRF Inverter KX4/KXR4 Multi-system is the result of the standards of excellence reached by Mitsubishi Heavy Industries after years of impassioned technological research in the residential and commercial air conditioning sector.

KX4/KXR4 Ultra-compact Design The compact design of the outdoor units of the KX4/KXR4 series is unmatched, as all models from 8HP to 24HP have the same structural characteristics. The design and the reduced footprint dimensions make it possible to find a solution to many limits often dictated by the space available for installation.
Easy to transport The units are fitted with a practical base which makes it easy to lift and transport them; no wooden pallet is required, just a forklift truck, a hoist or slings passing through the holes in the base. Furthermore, as there is no difference between master and slave units, no special components are required, nor is any particular transportation and positioning of the unit, making the installation work fast and easy.
KX4/KXR4 The Superlink® centralized control system The exclusive Mitsubishi Heavy Industries Superlink fast data transmission system, which in the past was only dedicated to highly sophisticated systems, is used today to connect residential and commercial air conditioning units in a network and control them from a remote station, optimising the management of small, medium and large surfaces. Up to 48 units can be connected in a network per line, and controlled from a remote station.

KX4 KX4 modular heat pump systems Heat pump units Thanks to its compact and modular characteristics the KX4 series heat pump system meets the new air conditioning requirements of medium and large buildings to perfection, with cooling and heating operation of all the indoor units connected. The system can condition a single flat or a whole multi-storey building, and is suitable for particularly vast open space environments.
It is possible to programme the operating mode of the system for cooling or heating using selector SW37 installed on the PCB (Printed Circuit Board) of the outdoor unit. This lets the users of the building define the operating mode of the system, for example only cooling in summer, and only heating in the winter, avoiding unwanted energy consumption. Furthermore, it is possible to install the control switch in a remote position in the building or connect it to a room thermostat.

KX4 Refrigerant piping The KX4 system is manufactured in accordance with the highest standards of quality and reliability and therefore it is essential that the methods of installation and materials used have the same qualitative characteristics, to guarantee long-term trouble-free operation. We recommend using copper refrigerant pipes, which must be chosen allowing for the greater operating pressure of the R410A refrigerant gas.
Electrical connections Connecting the power cables Power (outdoor unit side) Three-phase 380/415V 50Hz The new KX4 system has very simple electrical connections with the indoor unit, thanks to a control circuit with 2 non-polarized wires. The power wiring can be passed through the prepunched holes in the front, right, left or rear of the outdoor unit. A separate power line must be installed for outdoor units and 3-phase outdoor units.
KXR4 KXR4 modular heat recovery systems Heat recovery unit The KXR4 heat recovery system offers simultaneous cooling and heating modes for the single indoor unit to meet the needs and characteristics of the environments to condition. Thanks to highly sophisticated control systems it is possible to condition several indoor environments, with different cooling or heating requirements, such as in the case of buildings exposed on 4 sides, where the heat gain/loss varies notably in the different zones.
The refrigerant connections of the KXR4 heat recovery system follow one route, with two pipes connected to the PFD flow divider and the third connected directly to each indoor unit off the main refrigerant line. This reduces the number of welds to execute in situ and, therefore also the time required for installation. The PFD flow divider is available for single connections or 4-way connections, where each unit connected operates independently in the cooling or heating mode.
