Revision 1.1 Page 12
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 30-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 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 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.

Revision 1.1 Page 14
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) Remove the filters and flush (5-gallons recommended). Reinstall filters. Note that the filters
are a reverse-thread. Ensure proper filtration for local water conditions.
8) Establish 40–60 psi 0.5 gal/min or greater potable water supply. Leak Protection is
recommended.
9) 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).
10) 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.
11) 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.

¼” Plastic Tubing, at least 4 feet in length, and assorted ¼” quick connect fittings.
TDS Meter and Test Strips for measuring chlorine. - Optional
1/8 NPT Female Thread to ¼” Compression Fitting (Used to connect hose to drain fittings)
Beverage Head to flush Waterlogic Filters (Q Series –LH thread). - Optional
1. Unpack the Waterlogic WL500 and check exterior for damage.
WARNING! WL500 IS HEAVY.
Use proper lifting aids and handling techniques to avoid injury. Use assistance as single
person lift could cause injury. Always drain before handling and transporting and handling
to reduce the weight of the unit.
2. Remove the Retaining Screw that is located directly in
front of the faucet nipple. Refer to Figure 1. Removing
this screw will 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.
WL500 contains 2 Carbon Filters that must be flushed or removed before use to avoid
contaminating WL500 with carbon fines. Never rinse filters through solenoids or tanks.
4. Remove the 2 filters that are inside the front hatch cover. Remember that these filters are
reverse-threaded into beverage heads, and you must turn them clockwise to remove.
5. Utilizing extra beverage head, rinse the carbon filters. Alternatively, filters can be flushed in
unit by removing the right side panel to access the beverage head outlet hose and flush to
drain using an extra piece of ¼ line.

Revision 1.1 Page 19
6. Flush thoroughly (at least 5 gallons) with fresh water to clear carbon fines. Test outlet water
with TDS (Total Dissolved Solids) Meter to determine exact flushing volume required.
7. Once rinsed, reinstall the filters. The PU-4029 (CBC) filter should be installed in the filter
port that is on the left side of the faucet and the PU-4076 (GAC) should be installed in the
filter port on the right side of the faucet (as you face the front of the machine).
Internal Filter Bypass Instructions
The WL500 has a CBC Filter and GAC Filter installed behind the front access panel. These filters
are reverse thread and the first filter head has an internal shut-off valve that requires a filter to
be engaged to allow water to pass through it. Alternative filtration may be required to best
meet your local water and business needs. The WL500 internal filter heads can be bypassed
internally by removing side panels and running a new ¼” JG tube from the inlet bulkhead to the
inlet solenoid tee. Always check for leaks after installing and ensure the tubing is routed away
any moving or hot parts to avoid potential damage.
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).
8. Remove the UV Cover Plate and set aside –2 Screws.
9. Disconnect the UV Lamp harness and carefully remove the UV Lamp from the quartz sleeve.
CAUTION! UV SYSTEM IS FRAGILE. Never handle the UV System with bare hands. UV

Fill the Sparkling Chamber with Sanitizer
20. 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
21. Place a pitcher, catch basin, or other container under the faucet of the WL500.
22. 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.
23. 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.
24. The sanitization process for the Cold and Sparkling Circuits is now complete.
