2. Why a cooling unit for wine cellar? To ensure its optimal ageing, the wine needs an environment which respects the essential parameters for its good evolution (constant temperature, controlled humidity, permanent darkness, air circulation, absence of vibrations, adapted storage). Traditionally, the wines are stored in natural cellars where these essential criteria are respected for their good evolution. But a beautiful cellar is not automatically a good cellar. Thanks to technology and with materials available on the market, we are able to recreate today a dedicated space with these optimal conditions in contemporary houses. And all that for a reasonable price. Following some simple rules, using existing space or building a dedicated one, will be more effective than certain natural cellars. 2

3. COOLING UNIT FOR WINE CELLAR AIR-CONDITIONER FOR APARTMENT Temperature accuracy To the degree Precision within 3°C Temperature setting range Between 9 to 15°C Between 18 to 25°C Hygrometry Hygrometry maintained (>50H%) Drying of air (<50H%) What are the differences with a home air-conditioner? Each unit has its own use The air-conditioner maintains the temperature of a room at the chosen level, but the temperature precision is inaccurate and it also dries the air. The difference of temperature between the inside and the outside should not exceed 10°C for a normal operation. The cooling unit dedicated for wine cellars operates in regard to the perfect conditions for ageing wines, in particular by controlling the temperature within one degree, while maintaining the hygrometry necessary to the sealing of the bottle corks. 3

4. How does the INOA unit operate? INOA is a cooling unit equipped with a ventilated cooling circuit. The cold system consists in making constant circulation of the air around the bottles inside the cellar. The air is then drawn towards the evaporator through which it cools and brings apart moisture that it contains, before starting its cycle again. The presence of a heater element integrated in the unit maintains the wine at its right ageing temperature in the event of important drop of the outside temperature. INOA is designed with an integral body made in one piece (monobloc). The evaporator and the condenser are interdependent in the same volume. The design of the unit allows any exchange between the inside and the outside of wine cellar, therefore no loss of cold power. 4

6. Installation An easy installation The INOA unit is ready to be installed. No cooling pipe junctions are necessary, no need for gas filling. The right thing to do is to determine the right location for the unit and to drill 2 holes (Ø210mm) in the wall. The INOA unit is held with an adapted bracket on the wall. An electrical plug or junction box has to be used to connect the unit to main electrical power. A circuit breaker is recommended. 6

10. Installation Installation on the door INOA installation onto the door of a cellar is possible. This requires an adapted solid door to avoid vibration which could damage the unit. Of course, it is essential to check that the door is capable of supporting a weight of 46kgs. The procedure for fitting stays the same as for the wall. 10

11. INOA various installation Easy to install INOA can be placed inside or outside the cellar, fixed to a wall in upper position or nearly on the floor. In any case INOA has to be screwed to the wall through a specific frame bracket (which comes with the unit). We recommend to fix INOA as high as possible in order to optimize the air convection in the cellar (leave a space of 200mm between the ceiling and the unit housing to make it easier to fit INOA onto its frame bracket). 11

14. Installation Things to know Before any installation, it is of the highest importance to know the general characteristics of the environment of the cooling unit. It is necessary to take into account the volume of the wine cellar, the thickness and insulation of the walls, door, ground and ceiling, ventilation and size of the adjacent room. A perfect insulation is of prime importance to obtain the best performances from the INOA unit. A lack or an absence of insulation multiplies by 3 the power necessary to air-cool the same volume and it increases electric consumption. The traditional materials of construction such as stone, concrete or brick are very bad insulators and only the walls in the earth represent a suitable natural insulation easily. It is thus essential, in the majority of cases, to envisage the insulation of the whole cellar to be air-cooled. There are several types of insulating materials but the performance of each one is characterized by its thermal conductivity coefficient and its thickness. 14

15. Installation Things to be done To obtain the optimal performances of INOA unit, we advise to insulate all parts of the cellar with extruded polystyrene of minimum thickness of 80mm, the most efficient and economical on the market (extruded polystyrene 80mm corresponds to 4.80 m of stone wall!). Moreover, the extruded polystyrene panels have the advantage to be assembled into each other to avoid the cold power losses. It is essential to make insulation of the whole cellar to be air-cooled (walls, door and ceiling). On the ground, beaten ground, or few centimeters of sand and gravel support the insulation and the presence of humidity necessary for the good wine ageing. Never forget that, from its operation, a cooling unit rejects warm air from its condenser part. A good ventilation of the adjacent room is important to preserve optimal performance of the unit. The temperature of this room will never have to exceed 35°C (95°F). If it is not the case it will be necessary to add an extractor of hot air (flow at least equal to the hot flow outlet of the air-conditioner = 600 m3/hour (355 cu.ft./m) for INOA25 and650 m3/hour (385 cu.ft./m) for INOA50. After perfect insulation of the wine cellar, finishing touches can be applied in order to make the part more aesthetic and to avoid possible particle emissions from insulating material in the atmosphere. 15

16. Installation Things not to be done The presence of windows or picture windows in the air-cooled wine cellar is excluded. In the air-cooled wine cellar, the presence of sources of heat (heating by the ground, the piping of heating, radiator, boiler,…) is also to be avoided. In a long narrow room, never install the cold air exhaust of unit widthwise. It would disturb the homogeneity of the temperature and the good air circulation inside the cellar. A strict but simple requirement = the wine lives well with the wine! The storage of other products in the cellar (vegetables, cheeses, vinegars, chemical products, etc.) is to be excluded to avoid fatal smells for the wine. 16

17. INOA advantages Temperature regulation by a remote control The regulation of the temperature as well as its display is carried out using a remote control. The remote control works by radio frequency (433,92Mhz). It is unidirectional system. The remote control is equipped with an integrated temperature probe. Thus way, it could be located closer to bottles and without taking into account the cooling unit location. If you wish to install the remote control outside of the cellar, it is necessary to use the wired probe delivered with the unit. The remote control is fitted with 2 batteries out, one operates and the second one is in spare. PS: Software modification of the remote control (from V10.3 to V10.4) on cooling units delivered since the 23/11/07 for improvement of the reading accuracy 17

18. INOA advantages Homogeneity of temperature INOA ensures a mixing of permanent air of the room, a descent in regular temperature of the bottles and a perfect homogeneity of the temperature. INOA recycles more than 500m³ of air per hour. Thus, in one hour, INOA brewed 10 times the volume of cellar which to be air-conditioned. The INOA performances. By design, there is an insulation condenser/evaporator which does not allow any exchange between the external and interior rooms, therefore no loss of refrigerating power. There is no exchange of air between the rooms and this fact no risk of external pollution of the cellar through the cooling unit. 18

19. INOA advantages Humidity control A classic cooling unit uses a circuit producing a lot of cold to quickly air-cool a volume of air. This system dries the air of a cellar. EuroCave finalized an exclusive technology which maintains a positive and constant evaporation temperature (above 0°C). This is why INOA does not dry the air inside the cellar by minimizing water condensation. The design of cooling circuit and automatic speed adjustment of condenser fan allow constantly a positive temperature balance. In addition, a drip tray with a water drain pipe is located under the evaporator. The collected water from air condensation can be put outside the cellar in case of high humidity level or in the opposite way it can be put inside the cellar in case of low humidity level. 19

Evaporator fan speed EV1 = Compressor stopped but evaporator fan operates to insure continuous aeration of the room / Silent mode EV2 = Heater element is on EV3 = Compressor is operating Condenser fan speed INOA advantages Energy saving The automatic speed adjustment of the condenser and evaporator fans taking account of surrounding temperature allows to avoid electrical over consumption. The INOA unit always operates at the right speed. In addition, positive and constant evaporation temperature (above 0°C) does not action the machinery too much. 20

21. INOA advantages • Soundless • Both condenser (warm air flow) and evaporator (cold air flow) fans are automatically inter-regulated to reduce their speed as much as possible. • Thus: • At 25°C of surrounding temperature, INOA is quite soundless • At 35°C of surrounding temperature (ex: hot summer period), the fans turn faster but noise level remains quite acceptable. 21

22. INOA maintenance • It is necessary to thoroughly clean the INOA unit’s condenser and evaporator exchangers every 2 years: • Unplug the unit • Place the unit on the ground by unscrewing the unit from the frame bracket • Vacuum the 4 air entry and exit grids • Remove the upper cover (2 screws) – Picture (1) • Snap off from the top the 2 black plastic sections in order to access the 8 screws of the front panel – Picture (2) • Disassemble the front panel by removing the 8 screws • Clean the ribs of the 2 condenser and evaporator exchangers with a vacuum cleaner – Picture (3) • Repeat these instructions in the opposite order to reassemble the appliance 22

27. In reply to your questions How to determine if a material is a good insulator or not? The performance of material insulation results in its thermal resistance R (m2.°C/W). It qualifies the aptitude of a material to conduct the heat. R = e /  The higher the coefficient R is, the better the insulation is. Thus it depends: On the coefficient of thermal conductivity  (W/m.°C) which qualifies the aptitude of a material to conduct the heat. The smallest the coefficient is, the better the material insulates. On the material thickness e (m). The thickest the material is, the better it insulates. 27

28. In reply to your questions What does relative humidity mean? The relative humidity is the ratio between the real quantity of steam in a specific volume of air and the maximum quantity that this volume could contain at the same temperature. This maximum quantity depends on the conditions of temperature and pressure, and fluctuates according to the areas, the seasons and the weather. How many wine bottles do you store in a room of 50m3 (1800cuft)? It is possible to store more than 5000 bottles in a cellar of 50m3 (1800cuft) (calculation based with Modulotheque design). 28
