WATERLOGIC WL500 PREMIUM SPARKLING OVERVIEW Waterlogic WL500 produces Premium Sparkling Water which is made in a batch and contains a fine, dense carbonation as compared to other “soda water” products in the market. Optimum sparkling water is generated in the WL500 with 41°F cold water and food grade CO2 at 42.5 psi (3 Bar). Please ensure customer’s carbonation expectations are clear before installing a WL500. Waterlogic Premium Sparkling Water is very similar to Perrier and Pellegrino. The premium fine dense sparkling water produced by the WL500 may not meet user's expectations if they are looking for large bubble soda stream type of carbonation. A blind taste test using Pellegrino/Perrier is a great way to demonstrate the expectations and quality of the Waterlogic Premium Sparkling Water. Open two bottles and empty one and fill with Premium Waterlogic Sparkling Water from a freshly regenerated tank operating at optimum conditions (41°F / 43 psi). Recap both and mark the bottles accordingly. Ensure the bottles are sampled at the same temperature by refrigerating if necessary for later use and comparison. Most users will prefer the great taste of the Waterlogic Premium Sparkling Water at a fraction of the cost of the bottled counterparts. You may purchase a carbonation tester from a company such as Taprite to measure the level of carbonation if you wish to quantify the results and check the output of the WL500. The level of carbonation is very consistent as long the test conditions are repeatable and proper testing procedures are followed. Temperature of the water in the WL500 has the largest impact on the taste and carbonation levels and the cold tank must below 46°F (prefer 41°F) before injecting water into the sparkling chamber (carbonator) to produce proper results. The temperature inside the cold tank can be displayed on the LDC screen by setting the temp display function to "Ranging" mode. See the programming section to adjust this setting. Allow a minimum of an hour for the WL500 to chill the cold circuit to the 41°F set point temperature before sampling the sparkling water. Once the water is chilled, the sparkling tank should be "Regenerated" by completely and continuously dispensing the initial batch (0.8 liters) of product from the carbonator until only Co2 gas is dispensing from the faucet. The initial batch of sparkling product will be flat because it was injected into the carbonator at ambient temperature when initiating the WL500. Always remember that the water must be below 46° F to make premium sparkling water. Do not set the cold temperature set point below 41°F or you increase the risk of freezing the sparkling tank. The thermistor that controls the refrigeration system is located in the well in the UV cold tank and does not monitor water temperature in the sparkling tank (carbonator). The refrigeration system chills both tanks simultaneously and is either on/off based up on feedback from the thermistor. Frequent or continuous use of the cold still water results in refrigeration system running and continuously chilling the sparkling product in the carbonator below freezing point. This can result in a frozen sparkling tank and sparkling product will not be dispensed even with proper gas supply.

WL500 PRINCIPLES of OPERATION It will take the WL500 approximately 10 minutes to heat 1.6 liters of water in the hot circuit and 45 minutes to chill the 4 liters of water in the cold circuit to set point temperatures after all tanks have been properly filled. The WL500 has two cold tanks; a 2 liter UV Cold Tank and a 2 liter Sparkling Cold Tank which is separated by a baffle/divider plate that isolates a 1 liter Sparkling Water Chamber from a 1 liter Pre-Chill Chamber within.

Dispensing Cold Still Water from the WL500 The WL500 defaults to cold water selection when idle. “COLD” will appear on the display and cold water will be dispensed when the Main Dispense Button is pressed. Selecting COLD (Button 1) and then pressing the Main Dispense Button opens Solenoids 2 and 4, which allows supply water to push into the Pre-Chill Chamber of the Sparkling Cold Tank. Pressurize feed water pushes into the bottom of the prechill chamber and forces pre-chilled water through the tall draw tube into the bottom of the UV Cold Tank. UV treated, cold, still water is forced out through the tall draw tube, through Solenoid 4, out the faucet of the dispenser. When the main dispense button is released, both Solenoid 2 and 4 will close, thus stopping cold, still water output. The WL500 is a pressure fed unit and output is dependent on supply. WL500 Operating, Installation, and Service Manual

Page 10 - Revision: 5-29-2015

Dispensing Hot Water from the WL500 To dispense hot water, select the small HOT (Button 3) and release. HOT will appear in the display, and press the Main Dispense Button. This will open the hot input solenoid (Solenoid 1– not shown above) and allow hot water to dispense through the faucet. The WL500 can be programmed to default back to COLD or Sparkling after 3 seconds of inactivity as a safety feature to prevent accidental dispensing of hot water. Dispensing Extra Hot Water from the WL500 Typically, the WL500 hot water temperature is set to 189o F. In some cases, extra hot water is desired for making soups and teas. To temporarily raise the hot water temperature, users can depress and release the EXTRA HOT select button (button 4). The word HEATING will appear in the display for 10seconds, which will raise the hot water temperature about 2 degrees. If the user presses the EXTRA HOT select button again after 30-seconds have expired, the word HEATING will appear in the display, and the temperature in the hot tank will be raised another 2o F. Eventually, as the process is repeated, the hot tank temperature will reach up to 203o F, and the extra heating will be disabled. At this point, 203o F hot water can be dispensed from the WL500, which is a desired temperature for soups/teas. The WL500 will return to the hot temperature set point after the extra hot water is dispensed. Dispensing Premium Sparkling Water from the WL500 To dispense sparkling water, press and release Sparkling (Button 2). SPARKLING will appear in the display. From this point, the user has 3-seconds to press the Main Dispensing Button for Premium Sparkling Water. The unit will default back to COLD water after 3 seconds unless the Default Set is changed to Sparkling. (See Programming Section) When the Main Dispensing Button is pressed, Solenoid 5 will open, and the CO2 gas supply from the bottle will push sparkling water out of the sparkling water chamber to the faucet. The CO2 supply is what forces sparkling water out of the sparkling chamber. The sparkling water chamber is 1 liter in size and a maximum of 1 liter of sparkling water can be dispensed to the glass at a time. Once the sparkling tank empties of sparkling water, only CO2 gas will dispense to the glass. At this point, the main dispensing button must be released to allow the WL500 to make another batch of Premium Sparkling Water. When the Main Dispensing Button is released, Solenoid 2 and 3 will open, and the Booster Pump will start the Mizzling Process. The Booster Pump will draw cold, still water from the Cold Tank, forcing that water through Solenoid 3 and the check valve into the spray header inside of the sparkling chamber. The spray will enter the sparkling chamber as a fine mist that will absorb the CO2 gas that is present in the chamber. Once the sparkling tank fills with water, the level probe mounted in the top of the sparkling tank will detect the water and signal the PCB to shut down the booster pump, as well as close Solenoid 2 and 3. Note that the booster pump can supply this spray up to approximately 70 psi, and if the CO2 gas pressure is too high, the booster pump will not be able to overcome the gas pressure, and will “dead-head”. If the booster pump runs for 10 minutes without a signal from the level sensor, the PCB will shut down the sparkling water process and signal a NO WATER SUPPLY FAULT will be displayed.

WL500 Operating, Installation, and Service Manual

Page 11 - Revision: 5-29-2015

Once the level sensor detects the tank is full of water, the PCB will shut down sparkling water generation (Mizzling Process). The WL500 will return to the COLD default selection after 3 seconds. Cold and Hot water can be dispensed while sparkling water is being generated. The sparkling water generation will stop as soon as sparkling water is dispensed or the chamber fills. The WL500 will make 1 liter (34 ounces) of sparkling water in approximately 1 minute, 20 seconds. Typically, users will only dispense up to ½ liter (17 ounces) of sparkling water at a time, and the WL500 takes about 40 seconds to regenerate sparkling water tank accordingly. Waterlogic WL500 produces Premium Sparkling Water which is made in a batch and contains a fine, dense carbonation as compared to some “soda water” products. Optimal sparkling water is generated with cold water under 46o F. WL500 Sparkling Level Sensor Probe requires inspection and service. See Service Section. WL500 Sleep Mode The WL500 has programmable sleep mode. When sleep mode is ON the WL500 will shut down the heater circuit to conserve energy after the machine is idle for 3 hours. The heater circuit will awake once any button is depressed and it will reheat the hot tank to set point temperature. “SLEEP MODE” will be displayed. Always check Sleep Mode setting if unit does not produce hot water as expected. WL500 UV Protection The Waterlogic WL500 contains a germicidal ultraviolet (UV) lamp that sterilizes water in the cold tank and requires annual replacement. The WL500 has a UV CDS Sensor located in the Cap of the UV Tank. UV Fault Mode Protection will alert the user with a 20 second audible alarm and display UV FAULT on screen when UV light is not detected. UV Fault Mode Protection will shut off cold/sparkling water to avoid potentially dispensing unsafe water.

WL500 QUICK START GUIDE Critical Requirements Establish Food Grade CO2 Supply and regulate to 35-45 psi. This will produce optimum sparkling water and CO2 concentration when combined with 46 F degree or cooler water. Regulate the Water Supply to 40–60 psi. ALWAYS use a pressure regulator. 1) Prior to setting the WL500 machine, open the knock-out on the back panel of the base cabinet to allow running the CO2 pipe from the base cabinet to the WL500 machine. 2) Unpack the WL500 and set on top of base cabinet so that the side panels of the machine align with the side panels of the base cabinet. 3) Secure the WL500 to the base cabinet using the bolt provided in the base cabinet. Note that the connection point is accessed from the underside of the base cabinet. The bolt threads into the WL500 base plate and locks the unit together. 4) Install a regulator onto a 5lb or 10lb food grade CO2 bottle and purge some gas from the bottle. Regulate output to 35-45 psi. Close the regulator outlet valve, and secure in the base cabinet. 5) Route a ¼-inch pipe from the outlet fitting of the CO2 regulator through the knock-out up to the CO2 IN bulkhead fitting on the back of the WL500.

Mounting Bolt Here

6) Slowly open and supply CO2 to the WL500 prior to establishing water supply and power. 7) Establish 40–60 psi 0.5 gal/min or greater potable water supply. Leak Protection is recommended. 8) Supply power to the WL500, and turn on the RED power switch (GREEN power switch MUST remain OFF until the WL500 tanks are filled or hot tank overload will trip). 9) Fill the hot, cold, and sparkling tanks by dispensing until water flows from each. The sparkling tank will self-fill after the cold tank is filled. Once tanks are full, turn on the green power switch to allow the heating and chilling systems to function. 10) Regenerate the sparkling tank by dispensing the initial batch of 1 liter from the chamber. Remember that the water in the cold tank needs to be cold (below 46 F) to make premium tasting sparkling water.

Filters need to be configured and specified to do the job given the local water conditions, usage, maintenance schedule, and placement restrictions. In order for our filters to perform as represented and to provide the best quality water possible, it is essential that filters be replaced periodically. The frequency of filter changes depends upon your water quality and your water usage. For example, if there is a lot of sediment and/or particles in your water, then you will have to change your filters more frequently than a location with little to no sediment. Be sure to replace your filters whenever you notice a decline in the performance, whether it is a drop in flow rate and/or pressure or an unusual taste in the water.

WL500 Draining Instructions WARNING! WL500 IS A HEAVY OBJECT. Use proper lifting aids and handling techniques to avoid injury. Use assistance as single person lift could cause injury. Always drain before handling to reduce weight. Draining Notes There are 3 tanks and a booster pump circuit that must be drained in the WL500. The cold still water circuit of the WL500 consists of a 2 liter cold tank, a 1 liter pre-chill chamber and a booster pump circuit that is sealed and must be vented to drain. The booster pump will have some water in the circuit that must be purged to remove it. The sparkling chamber does not have a vent or drain port and must be dispensed until empty (pushing CO2 gas only out of the faucet) to clear the water from the sparkling chamber. It is critical to clear the cold still water before draining the sparkling chamber to ensure the pump does not inject water back into the sparkling chamber. The hot tank has a drain port and is the only tank that is open to atmosphere through the vent and faucet. Prior to draining the hot tank, turn off the green compressor/heater switch, and dispense 2 liters of hot water from the machine. As hot water is dispensed from the faucet of the unit, colder water will be introduced into the hot tank. Since the green power switch is turned off, the heater will not energize and heat the incoming tap water. Following this precaution prevents exposing personnel and equipment (drains, catch basin, etc.) to scalding hot water. Disable Cold and Hot Tanks 1. Turn off the green power switch to disable the heater and compressor. 2. Dispense 2 liters of water through the hot tank to cool the water temperature in the hot tank and avoid burns. WARNING! VERY HOT WATER CAN BURN OR SCALD. Hot water should be dispensed carefully into insulated container to avoid injury. Turn off Water Supply and Bleed Water Pressure 3. Isolate the unit from feed water by turning off the supply. 4. Dispense cold still water to relieve any pressure built up in the system. 5. Remove the water supply line from the unit. 6. Install dust cap or plug into water supply line bulkhead fitting. Drain the Cold Still Water Tanks and Circuit 7. Open front hatch panel by unscrewing the retaining screw in front of the faucet until it is flush with the faucet. Slide front hatch panel up and out. 8. Remove the UV light cover plate and access the UV lamp and quarts sleeve. WARNING! ULTRAVIOLET RADIATION. Protect your skin and eyes against ultraviolet rays. Never look directly at an operating UV light. Disconnect UV lamp before removing. WL500 Operating, Installation, and Service Manual

DESCALING the HOT TANK 1. The hot tank requires removal of mineral deposits (descaling) on a regular basis, depending upon filtration and local water conditions. Descaling is an important process that removes calcium deposits, or scale, that can build up inside a tank over time. Calcium and scale is non-toxic but left unattended, it will hinder your unit’s performance. Hot Tank Troubleshooting: Hot water intermittently forced out through the faucet is an indicator that descaling is needed. This occurs when scale has deposited on the expansion slot inside the hot tank vent chamber and blocks the normal path for water to expand. Descaling should take place every 6 to 12 months to preserve the long-term health of your unit. Use non-toxic cleaner such as ScaleKleen, DEZCAL, 20% Citric Acid Solution, or Undiluted Vinegar Solution to remove mineral deposits as directed by the manufacturer. WARNING! PERSONAL PROTECTIVE EQUIPMENT REQUIRED. Always ensure proper ventilation and use rubber or nitrile gloves and eye protection when using chemicals. Refer to Material Safety Data Sheet for specific requirements of each product. CAUTION! STAINLESS STEEL TANK DESCALING. The hot tank is made from stainless steel. Ensure descaling solution is compatible with stainless and always flush the unit completely. Dispose in an environmentally safe manner. See Hot Tank Descaling Video and training procedure located on the Partner Area of the Waterlogic Website for more detailed instructions. www.waterlogic.us Materials Needed: • Personal Protective Equipment. Rubber or Nitrile Safety Gloves and Protective Eyewear • Phillips Screwdriver • Temperature Gauge • Water Pitcher or Container to collect water from the faucet • 5 gallon container or drain basin • Citric Acid Based Cleaner • ¼” Plastic Tubing, at least 4 feet in length, and assorted ¼” quick connect fittings • Sanitizing Cartridge • Food Coloring 2. Put descaler per directions and 3 drops of food coloring into the descaling cartridge. 3. Connect descaling cartridge to the inlet water supply and connect to inlet bulkhead fitting on the back of the unit. Turn on Water Supply. 4. Select Hot Water and depress the Main Dispensing Button on the Front Control Panel until descaling solution (colored water) comes out of the faucet.

FAULT CODES Display indicates “No Water Supply” NOTE: “NO WATER SUPPLY” fault appears when the booster pump runs for 10 minutes and there is not a signal from the level sensor to shut off the pump. This is a safety feature to prevent the pump from being damaged. When operating properly, it should take about 1-1/2 minutes for the pump to inject enough water to completely fill the 1 liter sparkling chamber.

Possible Reason Water supply has been shut off The filters have become fouled and plugged, thereby starving the booster pump of makeup water The CO2 gas pressure is above 45 psi, and the booster pump has dead-headed and cannot fill the sparkling chamber. The sparkling water level sensor has faulted and is not properly signaling the pcb to turn off the water injection pump once water fills to the probe level in the tank. No Water Supply error message will displayed and the pump will shut down after 10 minutes to prevent damage. Filter Counter is enabled and there is no signal.

WL500 Operating, Installation, and Service Manual

Solution Turn water supply on

Change Filters Turn CO2 gas pressure to 45 psi, verify with pressure regulator. Remove the probe and clean. Disconnect from power, shut off CO2 gas to isolate sparkling chamber and relieve pressure in tank through the Pressure Relief Valve before removing the probe. Disable the Filter Timer.

TROUBLESHOOTING Sparkling is Weak, Low Carbonation Waterlogic WL500 produces Premium Sparkling Water which is made in a batch and contains a fine, dense carbonation as compared to other “soda water” products in the market. Optimal sparkling water is generated with cold water and food grade CO2 set at 42.5 psi (3 Bar). Waterlogic Sparkling Water is very similar to Perrier and Pellegrino Sparkling Water. Temperature of the water in the WL500 has the largest impact on the taste and carbonation levels and the cold tank must below 46F (prefer 41F) before injecting water into the sparkling chamber (carbonator) to produce proper results. Warning! Do not turn up CO2 pressure beyond recommended setting of 45psi attempting to produce stronger carbonation level as the injection pump used in the carbonator will not be able to compress gas in the sparkling chamber and a "No Water Supply" error will result. The temperature inside the cold tank can be displayed on the LDC screen by setting the temp display function to "Ranging" mode. See the programming section to adjust this setting. Setting Customer Sparkling Water Expectation Please ensure your customers expect a Premium Sparkling Water similar to Perrier and Pellegrino versus a Soda Water or Soda Club type of product before installing a WL500. The WL500 sparkling water will not meet user's expectations if they expect a large bubble soda stream type of product. A blind taste test using Pellegrino/Perrier is a great way to demonstrate the expectations and quality of the Waterlogic Premium Sparkling Water. Open two bottles and fill one with cold Waterlogic Sparkling Water from a freshly regenerated tank operating at optimum conditions. Recap and mark the bottles accordingly. Please ensure the bottles are sampled at the same temperature you can refrigerate them for later use and comparison. Most users will prefer the great taste of the Waterlogic Sparkling Water at a fraction of the cost of the bottled counterparts. You may purchase a carbonation tester from a company such as Taprite to measure the level of carbonation if you wish to quantify the results and check the output of the WL500. The level of carbonation is very consistent as long the test conditions are repeatable and proper testing procedure is followed. User taste preferences will vary and it is critical that expectations are clear before installing a WL500.

WL500 Operating, Installation, and Service Manual

Page 47 - Revision: 5-29-2015

Always allow the WL500 to chill the cold water to set point temperature (allow up to 45 minutes to chill all 4 liters of water in the unit) before sampling the sparkling water. You or your customer must "Regenerate" the sparkling tank by completely dispensing the initial batch of 0.8 liters of product from the sparkling chamber once the unit has chilled to set point of 41F. The initial batch of sparkling product will be flat because it was injected into the carbonator (sparkling chamber) at ambient temperature when initiating the WL500. Always remember that the water in the UV treated cold tank needs to be cold (below 46 F) to make premium good tasting sparkling water. Do not set the cold temperature set point below 41F or you increase the risk freezing the sparkling tank. The thermistor that controls the refrigeration system is located in the well in the UV cold tank and does not monitor water temperature in the sparkling tank (carbonator). The refrigeration system chills both tanks simultaneously and is either on/off based up on feedback from the thermistor. Frequent or continuous use of the cold still water side results in refrigeration system running and continuously chilling the sparkling product in the carbonator to the point at or below freezing. This can result in a frozen sparkling tank and sparkling product will not be dispensed even with proper gas supply.

TROUBLESHOOTING Run On “Run On” or “Carry On” is present in all Waterlogic pressure fed units without outlet solenoids. “Run On” is defined as the amount of water that continues to dispense out of the faucet after releasing the dispense button. Run On exists because the tanks pressurize as water is being dispensed. Every Waterlogic tank has an outlet restrictor to ensure the tanks remain full of water and water is controlled as it is released to the faucet. The inlet solenoid controls flow into the tanks. The tanks will “depressurize” once the dispense button is released the inlet solenoid closes. A small amount of water will “Run On” through the faucet as the tank depressurizes to atmospheric conditions. Typical “Run On” is 2-3 seconds. “Run On” can be reduced by installing a pressure limiting device. The amount of inlet or supply pressure directly impacts the amount of “Run On” as quantified below.
