        INSTALLATION ORDER OF RESERVE CASSETTES FOR DOUBLE OR TRIPLE FILTER

        IMPORTANT: Place the inlet (3) and outlet (9) valves in the base or bases and wrap Teflon tape (not included) on their threads to avoid water leaks. ❶INSTALLATION (The customer is responsible for the correct and safe installation of the filter) The filter should be placed vertically under the sink, close to the water source, and its tap should be placed in the desired location on the sink. Cut the 2-meter hose included in the package into 2 parts of a size that allows the appliance to be removed from the cabinet when changing the filter. (If the hose is cut at an angle, you will have a leak). ❷ ATTENTION Make sure the water inlet hole in the filter follows the direction of the arrow on the underside of the metal base (1) of the appliance (see figure 1). If is connected backwards, the ceramic cartridge will clog or break . SINK HANDLE AMPLIFICATION – Drill a 11 mm (millimeter) diameter hole in the sink, at the desired location for the faucet (21), using a suitable drill bit ( drill first with a 6 millimeter drill bit ). – Before placing the faucet on the sink, first pass the nickel-plated metal base (20) through the faucet pipe, after removing the protective nylon layer, and pass the larger black rubber sealing washer (19) underneath. – Place the faucet in the hole you drilled in the sink, and on the side of the faucet located at the bottom of the sink, place the accessories (18), (17), (16) in the order shown in the drawing and screw the metal nut (15) completely to seal and fix the faucet to the countertop. – Pass the metal retainer (10) onto one end of the hose (11). Connect the hose (11) to the outlet nozzle (9) and screw the metal clamp (10) firmly. – On the other end of the hose (11), first pass the metal nozzle (12), then the oval plastic cylinder (nipple) (14) and then place the plastic wedge (13) inside the plastic hose to stabilize the nipple (14) in place. Screw the metal nozzle (12) firmly onto the thread on the tap stem. – Screw the cartridge (22) into the filter base (1) ( casual ), without tightening it too much, so as not to break it the plastic thread or ceramic filter or reduce the water flow. – Screw the metal cover of the appliance (2) firmly onto its base. Now open the tap and some black water may come out. FROM the filter tap for the first time, after rinsing the activated carbon . 3. CAREFUL: The first time and each time you change the cartridge, let the water run for 10 minutes. Do not use the filter for 24 hours. After the 24 hours, let it run for 2-3 minutes and the filter is ready for use. Also, if the filter remains unused for more than 3 days, let the water run for 2-3 minutes. 4. CAREFUL: Only use cold water through the filter. If you use hot water, the binding and sealing materials of the cartridge will come loose and sediment, mud, rust, as well as chemical elements in the water such as chlorine, etc., will not be retained by the filter. 5. FILTER REPLACEMENT (CASSETTE) When replacing or cleaning the ceramic cartridge, it is a good idea to make sure that any cuts or wounds on your hands are covered to avoid contact with germs that may have settled on the outside of the ceramic filter and that the antimicrobial copper in the base has not yet been able to destroy them, as it takes approximately 2 hours to destroy them. Otherwise, to replace the cartridge, follow the procedure as for the initial installation of the filter. To unscrew the metal cap (2), first turn off the water supply to the filter and at the same time open the filter tap (21) on the sink to release the pressure and unscrew the metal cap (2) more easily. Turn off the water supply to the filter when you want to: A) Completely shut off the water supply to the filter. B) Clean the cartridge. C) Replace the cartridge. D) When you are away from home for several days. 6. MAINTENANCE – CLEANING THE CERAMIC CASSETTE Every 3-4 months or whenever the water flow from the appliance tap decreases visibly (which means that the ceramic filter cartridge has become "clogged" with sediment, rust, mud, sludge, limescale, etc.), remove it from the appliance and, with cold water under the tap (without detergents), rub it well over the entire surface with the metal side of the dish sponge, or with a harder metal material, or even with sandpaper (number 80) to clean it and improve the water flow. After rinsing it thoroughly, put it back in place. 7. RECOMMENDED FILTER FLOW – IT’S TIME TO REPLACE THE REPLACEMENT CASSETTE IMPORTANT: The highest filter efficiency is achieved when the water flow through the filter does not exceed 1.5 to 2 liters per minute. The cartridge capacity is for 14,000 liters of water or for 10-12 months , whichever comes first. The cartridge life may be reduced in cases of networks loaded with impurities such as mud, rust, silt, earth, limestone, etc., or in periods of drought, when the load on the water supply networks is very high (due to low water levels). In these cases, the filter must be cleaned much more often and replaced earlier if, despite its cleaning, the water flow from the appliance tap is not restored. But regardless of the number of liters of water that will pass through the filter, you MUST replace the cartridge at least every 10-12 months, because from the moment it gets wet, its materials weaken month by month, and the water that passes through the filter will pass unfiltered. 8. MAINTENANCE OF THE DISC AND ANTIMICROBIAL BASE On the surfaces of antimicrobial copper alloy materials, and more specifically inside the base (4) and the disc (6) located therein, superficial discoloration may occur due to natural oxidation of the antimicrobial copper, deposits of various materials originating from water supply networks, such as rust, mud, etc. In these cases, these deposits, which do not hinder the overall operation of the filter in any way, are good, both for aesthetic reasons and for reasons of cleanliness of the filter chamber, be removed in the following way: a) Clean both surfaces of the antimicrobial disc thoroughly with something rough, such as pot wire, coarse sandpaper, etc. b) Clean the inside of the antimicrobial base in the same way to remove any rust-like deposits. 9. METAL DEVICES CLEANING PROCEDURE: Wipe the appliance with a soft cloth slightly dampened with lukewarm water. Avoid using bleach or any chemical detergent or bleaching agent, or metal scouring pads, as these will leave marks on the metal surface of the appliance. 10. IMPORTANT To protect the filter, after any interruption to the water supply, open the ever the tap and let it run for a while before using the filter. 11. WARNING The OLYMPUS+ water filter is intended for use in waters controlled by municipal or local authorities and which are suitable for human consumption. 12. BEWARE OF WATER PRESSURE If the network pressure is high, install a pressure reducer before the water filter. But, regardless of whether the network pressure is high or low, ENSURE that you install a one-way valve (anti-shock) (available in plumbing stores), so that in the event of a sudden increase in network pressure or of a momentary snowfall, hoses or the filter unit do not break and cause flooding. When leaving home for several days, you should always turn off the filter's water supply tap. View the product instructions in PDF format by clicking here.

Double water filter OLYMPUS + GIGA for under the counter (antimicrobial) has a shelf life of 1 year or 14,000 liters of water (whichever comes first).

TESTED BY:

  • 3 Certified European Chemical Laboratories
  • Agricultural University of Athens for bacterial retention (2010)
  • The Microbiology Laboratory of the Faculty of Medicine of the University of Athens for the destruction of microbes inside the device

MADE BY:

  • Ceramic materials and activated carbon

  • Stainless steel and antimicrobial copper alloy parts (CW606N and CW508L) registered with the US Environmental Protection Agency (EPA).

GLOBAL INNOVATION: The OLYMPUS+ antimicrobial water filter is a world innovation patented by CENTER PLUS SA, being the only water filter in its category that has an internal antimicrobial protection system, ensuring increased safety for users, having the ability to continuously destroy up to 95% of the microbial flora of pathogenic microbes within 2 hours, which the micropore ceramic filter retains and, at the same time, permanently disinfects the internal chamber of the device (self-disinfection). SCIENTIFIC - MEDICAL DOCUMENTATION: The OLYMPUS+ antimicrobial water filter was developed and manufactured by CENTER PLUS SA. The scientific documentation of the product for the destruction of microbes inside the device was carried out by the Microbiology Laboratory of the Faculty of Medicine of the University of Athens, which for 12 consecutive months studied and finally MEDICALLY CONFIRMED the antimicrobial action of the OLYMPUS+ water filter in collaboration with the scientific team of the Hellenic Institute for Copper Development (GIRM). UNIQUE ANTIMICROBIAL PROTECTION SYSTEM: The combination and careful arrangement of the antimicrobial parts of the device constitute the revolutionary OLYMPUS+ Water Filter Antimicrobial Protection System, as the continuous release of copper ions destroys the cell membrane and DNA of microbes on their contact surfaces, both in the device chamber and on the surface of the ceramic filter, due to the halo effect (Hallo Phenomenon), which is a property of copper to destroy microbes even at a certain distance from the copper.

INSTALLATION: In the case of the undercounter filter, installation can be done either by yourself or with the help of a plumber, by drilling a small diameter hole in the sink to place the stainless steel faucet.

DIMENSIONS:

  • OLYMPUS+ GIGA width 9 cm x height 31 cm each column (total 2).

CONSUMER SAFETY: Suitable for waters controlled by municipal authorities and which are fit for human consumption.

If your water is not potable, our company recommends that you, before purchasing any filter, contact your supplier (where you pay your water bill) or the municipality and request a chemical and microbiological analysis of the water. Based on this analysis, we will be able to recommend the model that will cover 100% of your network's needs.
