Winemaster C50S(SR) USER MANUAL
Complete Insulation
The insulating elements should preferably be "tongue and groove" type panels or panels fused together to ensure
perfect continuity of the insulation. This is necessary to avoid the intrusion of heat and humidity which can alter
the functioning of the WINEMASTER.
IMPORTANT: The warranty is only valid if the insulation is in compliance with the "Minimum Thickness
Requirements" for all walls, doors, floors, and ceilings with perfect continuity of insulation.

6.3. CHARACTERISTICS OF THE INSULATORS
• Thermal conductivity: λ
- This is a characteristic of the insulating material itself. It qualifies the capacity of a material to
conduct heat. The smaller the coefficient, the better the insulator.
• Thermal strength: R
- This is a characteristic of the insulated panel. It depends on the thickness coefficient of the insulator.
R = thickness in meters
The R value qualifies the ability of a material's thickness to stop the transmission of heat. The greater the
coefficient, the better the insulator.
6.4. INSULATION OF THE WALLS AND THE CEILING
When deciding on which type of insulation to use, there are three possibilities:
Traditional insulation
"Complex"insulation: insulation is covered with a facing (plaster, ore...etc.)
"Sandwich" panels: insulation is covered on each side with a wooden panel or plasterboard.
The covering of the panels is important; it protects the insulation against damage and guarantees its longevity.
Please note: Do not use insulators composed of mineral fibres.
Protection from rodents:
Check whether the cellar shows the presence of mice or rats. Some insulating materials are damaged by
rodents. If necessary, cover the insulation with a protective lining on the interior of the cellar. Polyurethane is an
insulator that, due to its chemical composition, is not attacked by the rodents.
