No, not when your dispenser meets the relevant hygienic food standards in relation to WE (Watercoolers EU) and NSF (National Science Foundation) regulations. The sanitation of the water dispenser is the cleaning and disinfection of all parts that come into contact with the water in order to avoid microbiological contamination. Dolphin water dispensers are equipped with food grade replaceable or fixed water reservoirs that meet the industries legal obligations and association standards (WE and SWCA)* and are regularly sanitized to these standards and by properly trained personnel**. This guarantees the dispensing of safe and healthy water during the entire period of use of the dispenser. To cover facilities that do not meet the corresponding standards, the association has adopted some alternative hygiene tools to avoid the risk of contamination. Dispensers with a lower quality level (like non food grade plastics) can therefore be equipped with an ozone-based tool (so-called SIP unit) or a UV lamp. These work like an airbag principle, i.e. if the device or its parts that are in contact with water are contaminated in any way, using ozone can kill pathogens and prevent the accumulation of algae. It is the same with the UV lamp, which disinfects the water at the point of delivery with the same effect. You should preferably choose a device without this necessity, since it is not clear to you, as a customer, whether this disinfection tool works correctly under all circumstances. Both an ozonizer and or UV devices do not clean the dispenser parts from dirt, scaling or contaminations other than microbiological. Furthermore an ozonizer can be damaged or the concentration level can change, and the UV lamps can be switched off, broken or the glass can be dirty to the point that it does not work properly without the knowledge of the consumer. If you want to be sure that your dispenser is safe, choose a SWCA supplier and ask for a certificate of conformity. Warning! Ozonation may result in the formation of the potentially toxic oxidation byproduct bromate and can cause serious health issues. The use of ozone for disinfecting water is recommended only in a controlled and well monitored surrounding. *SWCA members are regularly audited by independent NSF authorities to prove that they meet all standards and legal requirements and that their products comply with industry and European and national regulations. Ask for your supplier's audit certificate! **According to SWCA rules, all employees who perform sanitation must have successfully completed HAC (Hygiene Awareness Course) training in order to perform sanitation at your dispenser. Ask your supplier for your food handlers certificate as evidence! Note: a checklist is available to review all quality standards and compliance with legal and industry standards on www.swca.sk.

Sanitation is recommended to be performed by a trained food handler using food grade chemicals compatible with the material of the dispenser and its parts. If you decide to perform sanitization yourself, we take no responsibility for the results. Hygienic cleaning is also recommended to be performed by a Dolphin food handler, but you can do it yourself using a soft cloth and food grade detergent. The drip tray of the cooler is removable and can be washed in a regular dishwasher or sink with warm water and soap. Faucets should be thoroughly rinsed with clean water after washing and disinfected with a food grade disinfectant spray. Hygienic cleaning is a reduced form of sanitation and includes: Sanitation of the non-spill system (bayonet system for the entry of bottled water); Cleaning or replacement of the drip tray; Cleaning or replacement of faucets; Cleaning of the exterior of the dispenser.

The recommended frequency of sanitation depends on the type and model of the dispenser and reservoir and on the conditions in which the dispenser is located. The first sanitization is always performed by Dolphin before the first installation. Dolphin recommends at least two sanitizations per year for a bottled water cooler or filter cooler, conforming to the international industry standards and guidelines.

Bacteria are everywhere, and many of them are not harmful. However, to ensure a clean and healthy drinking experience using the dispenser, we strive to reduce the build up of pathogens. Keeping the dispenser clean and regularly sanitized is the way to do it. The Slovak Water Cooler Association follows internationally tested and approved guidelines for determining the correct frequency of sanitation for you.Extra sanitation can always be performed by our experts if the dispenser is located, for example, in a polluted or dusty environment, or in a place where there is a higher risk of contamination (e.g. schools, hospitals, heavy production sites). As a user, you should always observe the user instructions and make sure that the cooler is suitable for water consumption at all times. Make sure the drip tray is regularly emptied, keep the dispenser cleaned from dust or dirt, and also make sure the water bottles are placed in a clean location. Promote hand washing before using the dispenser.Do not hesitate to contact us or ask for cleaning if you have doubts about the cleanliness of the dispenser, or if you are interested in advice on how and when your dispenser must be sanitized.
Important: Sanitation should be performed regularly by professionals using chemicals compatible with the equipment's material and following the proper guidelines and instructions. If you decide to do the sanitation yourself and not have it performed by a Dolphin food handler, we can not be held responsible for the result.

Hygienic cleaning is a reduced form of sanitation and includes: Sanitation of the non-spill system (bayonet system for the entry of bottled water); Cleaning or replacement of the drip tray; Cleaning or replacement of faucets; Cleaning the outside of the cooler. Descaling accumulation of calcium inside the cooler can result in clogging or malfunctioning of the device. It can also lead to increased energy consumption or decreased water flow. Descaling the appliance requires food grade descaling chemicals compatible with the material of the hot tank material and must be carried out by a professionally trained technician. If necessary, during descaling, the hot water tank will be dismantled and replaced with a new one. We recommend descaling the dispenser at least once a year, especially for coolers with hot water. If you are interested in descaling, please contact us. Sanitation is the process of hygienically cleaning and disinfecting the external parts (see "Hygienic cleaning"), as well as cleaning and disinfecting (or replacing in case of a removable reservoir dispenser) the internal parts of the dispenser that are in contact with water. Complete sanitation covers: The outer part of the cabinet; The drip tray; The Non-spill system; Reservoir, baffle and faucets.

For bottled water coolers: These dispensers can be installed practically anywhere where there is a 220V power supply available within 1 meter. The dispenser must be installed on a flat surface. For hygienic reasons we recommend not placing the dispenser in direct sunlight, near a heat source, near waste disposal or in a damp or dusty environment, or at any location where potential contamination could occur. Bottles, full or empty, must be stored in a cool, dust-free environment, not in direct sunlight. This is the correct way to maintain good quality. Coolers and bottles should not be placed outside. For filter water dispensers: These dispensers are directly connected to the mains water supply and must be located within approximately 2 meters from the nearest water supply with a 220v power socket available within 1 meter. The installation also requires plumbing if a fixed water valve is not available. Depending on the water pressure and the quality of the plumbing work, it is also necessary to install a pressure regulator and a waterblock/ overflow prevention. A filter cooler can be installed practically anywhere where a mains water supply is available. The dispenser must be installed on a flat surface. For hygienic reasons, we recommend not placing the dispenser in direct sunlight, not near a heat source, near waste disposal or in a damp or dusty environment, or in any location where potential contamination could occur. Dispensers should not be placed outside.
