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 CO2at 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 Operating, Installation, and Service Manual Page 9 - Revision: 5-29-2015

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.
WL500 PRINCIPLES of OPERATION LAYOUT
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 pre-
chill 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.

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 189oF. 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 10-
seconds, 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 2oF. Eventually, as the process is repeated,
the hot tank temperature will reach up to 203oF, and the extra heating will be disabled. At this point,
203oF 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 CO2gas supply from the
bottle will push sparkling water out of the sparkling water chamber to the faucet. The CO2supply 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 CO2gas 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 CO2gas 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
46oF.
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 CO2Supply 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 CO2bottle 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 CO2IN bulkhead fitting on the back of the WL500.
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.

allow access to the inside serviceable components (filters and
UV lamp).
3. Open the front hatch cover by lifting up and hinging outward.
Front hatch cover can be removed by carefully squeezing panel
base and pulling over hinge pins.
Flush Filters
CAUTION! FILTER FLUSH REQUIRED.
WL350’s are not supplied with filters. Filters should be configured to optimize your system. 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 Operating, Installation, and Service Manual Page 17 - Revision: 5-29-2015

4. Flush thoroughly per filter manufacturers’ recommendation with fresh water to drain.
5. Once flushed, install the filters. Following the flow direction on the filter.
NOTE: Filters should not be flushed prior to 24 hours before installation to limit Microbial Growth.
Sanitizing
Sanitize using a household bleach solution or other approved cleaner throughout the cold and sparkling
water circuits. Follow all instructions on the sanitizer and flush with fresh water through the faucet
until odor and taste is acceptable.
WARNING! USE PROPER PERSONAL PROTECTIVE EQUIPMENT
Always ensure proper ventilation and use proper personal protective equipment such as gloves and eye
protection when using chemicals. Refer to Material Safety Data Sheet for specific requirements of each
chemical product. Take all necessary precautions to prevent sanitizer from contacting eyes, clothing, and
any other surfaces in could damage (carpets).

entire manual should attempt to install or service this unit.
16. Connect WL500 to power, and turn I=ON the Red Power Switch.
CAUTION! NEVER TURN ON HEATER BEFORE FILLING HOT TANK.
Green Compressor/Heater Switch must be in the O=OFF position while the hot tank is empty.
Damage could occur within one minute and the overload (high limit) will require manual reset if
heater is turned on with an empty hot tank.
Fill the Cold Circuit with Sanitizer
17. Wait 10 seconds for the unit to perform its diagnostics checks, depress the main dispensing button
on the front control panel until cold water/sanitizing solution comes out the faucet. NOTE:
Container and drain basin will be required to catch the water from the faucet.
WARNING! Use Personal Protective Equipment. Gloves and Eye Protection Required. The first 2
or 3 gallons of water will contain concentrated sanitizer. Use extreme care!
Fill the Sparkling Chamber with Sanitizer
18. The sanitizer solution will be injected into the sparkling tank by the booster pump once unit is
turned on and the cold tank is full. Dispense 1 liter of sparkling water into container and let
sparkling chamber regenerate to ensure the sparkling tank is full of sanitizer.
CAUTION! USE SANITIZER COMPATIBLE WITH STAINLESS STEEL AND ACETAL PLASTIC.
Do not allow the sanitizer solution to remain in the system for more then 10-15 minutes unless
otherwise directed by the sanitizer manufacturer.
Flushing the Sanitizer from the Machine
19. Place a pitcher, catch basin, or other container under the faucet of the WL500.
20. Flush the Cold Tank. Run several gallons of water through the faucet by dispensing cold water to
dilute and remove the sanitizer from the cold circuit. You can use chlorine test strips to evaluate the
water. Once the sanitizer odor/taste has been flushed out of the cold side of the machine, move to
the sparkling circuit.
21. Flush the Sparkling Chamber. Dispense sparkling water until only gas comes out. Let the sparkling
tank regenerate. This should take approximately 1 minute, 20 seconds. Listen for the booster pump
to turn off. Repeat the sparkling water regeneration until the sanitizer odor/taste has been flushed
out.
22. The sanitization process for the Cold and Sparkling Circuits is now complete.
