1. PRODUCT PRESENTATION
1.1 Principal Characteristics
• The reversible-cycle heat, water and air pumps have been designed for
domestic use and include inverter technology.
• MIRAI-SMI heat pumps are well known for their reliability (Made in
Japan) and relative energy efficiency. Partial-charge efficiency allows
for a high seasonal output level, along with the relevant savings in
air-conditioning.
• This cutting-edge technology guarantees an optimal comfort level for
users, both in terms of water temperature control as well as in terms of
extremely low noise levels. In fact, the required temperature is rapidly
reached without any fluctuations. The units are therefore capable of
providing optimal levels of comfort in both summer and winter modes.
• MIRAI-SMI heat pumps can operate in extreme temperatures.
1.2 Cutting-Edge Technology
• The large batteries are very efficient
• The twin rotary compressors (with inverter function) offer greater reli-
ability, lower energy consumption and are vibration-free in all opera-
tive conditions.
• The impulse modulating valve is a high-quality bi-directional balancing
device which optimises the unit and stops the refrigerant in circulation
from overheating by preventing the liquid from returning towards the
compressor. This device adds to the high performance and reliability
of the system.
• The adjustable-speed ventilators are equipped with patented rotor
blades and characterised by an innovative profile designed to guaran-
tee optimal air distribution and exceptionally low noise levels.
• The electronic control system is equipped with sensors located in key
positions of the cooling circuit to electronically detect the operating
status of the system. In fact, two micro-regulators receive impulses
from these sensors and process them using specific developed algo-
rithms to optimise the flow of the coolant and the functionality of the
most important components, that is to say the compressor, the ventila-
tor motors and the impulse modulating valve.
1.3 Ease of Installation and Maintenance
• By simply removing the cover on the electric panel, you can access
the electrical connections and the control/parameter setting devices.
• By removing the side panel, you can access the cooling circuit, the
hydraulic unit and the PCB (MAIN).
• The advanced design of the cooling circuit and the selection of compo-
nents render the unit exceptionally compact; it is easy to move even in
areas containing
narrow doorways.

2.1 Attention and dangers
Before using the air conditioner please read carefully the instructions ma-
nual. Producer decline every responsibility for any damage caused by the
non-observing of the following warnings.
When this manual has been read, please make sure that further unit users
will read it as well.
User has to keep this manual close to hand and has to give it to those who
repair and move the unit. Furthermore when there is an owner change,
please let the manual at disposal of the new user. Please make sure that
the following important safe information are strictly observed.
Unit is not intended to be used by persons with reduced physical, sensory or mental abilities, or with lack of experience or acknowledge
(children included) unless they had the possibility to benefit of some monitoring or using instructions through a person responsible for their
safety. Children have to be monitored to be sure they do not play with the unit.
This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack
of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved. children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without super-
vision. caution: do not expose the electronics of your charging and drying stand or the battery charger. There are no user serviceable parts insi-
de. Tefer servicing to qualified service personnel. please ensure voltage rating for enclosed battery charger matches standard outlet voltage.
Do not place animals or plants in the normal air flow of the unit.

rigorosa
Do not install the air conditioner in rooms where gas leakages or
other flammable substances could occur near the units.
Maintenance operations must be carried out exclusively by
qualified technicians.
Check the good condition of the installation media. Avoid blocking the air entry and outlet grids.
This could reduce performance or cause damage to the air
conditioner.
Do not install the air conditioner near sources emitting excessive
vapours (moisture, oils, etc.).

ON / OFF
If you experience abnormal phenomena (eg a burning smell),
disconnect the power immediately and contact your dealer for
instructions on what to do. In this case, continue to use the air
conditioner may cause damage and create the risk of electric
shock and fire.
Spe-
gnere
Do not disassemble the unit grid.
The exposure of the fan is very dangerous as it could hurt people.
Do not place objects and not climb on
Do not pour or spray water on the air conditioner. Do not put your fingers or other objects into the sockets / outlets
and deflector swinging while the conditioner is in operation. The
high speed of the fan is very dangerous and can cause injury.
Before any maintenance remove the power supply from the air
conditioner.
Please use fuses with the right amperage only.
(Never use pieces of cable to make temporary replacements.
This might cause fires too, not just a damage.
Note for draining water
Alta temperatura
The maximum temperature for the water in the circulation is about
60 °C. Be careful to avoid burns when draining the water.
