Now more than ever we must act urgently and responsibly to safeguard the future of our planet - and this is not so difficult. The following tips help you save energy (saving resources) the easy way, while reducing your business operating costs.
Installation and location
Install the appliance in a dry, well-ventilated room. The installation location should neither be exposed to direct sunlight nor near a heat source, e.g. a cooker, radiator, etc. Otherwise the refrigerating unit must work harder, increasing energy consumption and decreasing its life span. Make sure that you allow the required space around the equipment (rear and sides) for air circulation. Respect the climate class of the equipment. Never cover the ventilation openings on the rear and sides of the appliance.
Check the adequate temperature for the foodstuff to be stored in accordance with food safety legislation. Each type of food requires a specific conservation temperature range that should be respected. This is a key factor both in terms of quality and energy saving. For example: for a product that must be kept between around 4 ºC, if you change the equipment set point from 0 to 4ºC, it's possible to cut energy consumption by 4%.
Always place the products in the equipment at a temperature close to the operating temperature! Besides the food safety implications, loading hot foodstuff raises the compartment temperature, needing more energy to achieve the conservation temperature again. The closer to the correct temperature you place the products inside the equipment, the more energy you save.

Do not overload the shelves. Make sure that the load does not exceed the limit imposed by the existing label on the inside top of the equipment and distribute it so you leave enough spaces between the products, thus allowing for the correct cold air circulation. Never push products against the air blowing/suction grids to enable the air to circulate both over the products and in the evaporator. When loading, make sure that the air circulation is not obstructed in the evaporator area, since no air circulation in the evaporator favors the formation of ice on it, preventing its proper operation.
Open the doors of the refrigerated compartment as little as possible and never leave them open for long periods of time. Try to decide what you want to get out before opening the door and take several items at once. Be fast when you are picking up something from inside your equipment.
Maintenance is a vital procedure to keep your equipment running smoothly. Check regularly for dust accumulation in the condenser and ice build-up on evaporator(s). Keep all air circulation paths clear and unobstructed, reducing compressor operating times and, of course, energy consumption.
