INSTALLATION AND FLUSHING PROCEDURES
Safety and Installation Guidelines
Ensure all Local, State, and Federal Laws and Codes including health and safety guidelines are
met when installing Waterlogic Equipment. Only qualified service technicians should attempt
installation and service of Waterlogic Equipment.
WARNING!ELECTRICAL SHOCK HAZARD. Always unplug (isolate from power supply) to
prevent electrical shock except where electrical tests are specified.
WARNING! IMPROPER SUPPLY OR CONNECTION CAN RESULT IS RISK OF SHOCK.
Connect to a 15 amp, 120V 60Hz properly grounded outlet (GFI is recommended). Ensure
polarity is correct and always use a 3-prong outlet.Consult a qualified electrician if you
have any questions.
WARNING! USE ONLY Waterlogic SUPPLIED POWER CORD.Locate system within 5 feet of
power supply. Never use an extension cord or adapter. Do not use a damaged power cord
or plug. Keep power cord out of heavy traffic areas and away from heat sources. Do not,
under any circumstances, remove ground prong or alter the power cord. Never pull the
power plug from the outlet with a wet hand or allow the plug to get wet. Failure to use the
supplied power cord will void UL Certification and Warranty.
CAUTION! INDOOR USE ONLY. Never expose to direct sunlight, heat sources, or ambient
air temperature above 38°C (100°F) or below 2°C (35°F). Install indoors and keep unit away
from excessive humidity. Never expose to freezing temperatures. Ensure there is adequate
clearance around the unit to allow refrigeration system condenser to dissipate heat.
Warmer environments require more clearance around the unit. Minimum clearance around
all surfaces of the machine is 2-inches. Installs where the ambient temperature exceeds
80°F, require a minimum of 4-inches clearance for proper heat dissipation and efficient
operation.
CAUTION! USE A WATER PRESSURE REGULATOR. Waterlogic will not be responsible for
injury or damage caused by excessive water pressure. Operating pressure must be 40 psi to
60 psi. Be aware any of potential pressure surges caused by building/municipal pumping
stations.
CAUTION! USE UV STABILIZED SUPPLY LINES. Feed the unit with a potable ambient or
cold-water supply only. Feed water over 100° F (37°C) can damage the treatment
components. Water block devices and external leak detectors are strongly recommended.
Locate the unit as close to the water supply and the electrical connections as possible.
WARNING! STORE AND TRANSPORT UNIT EMPTY. ALWAYS SANITIZE BEFORE USE.
The unit must be completely drained and sealed before storing to avoid stagnation and
reduce microbiological contamination (potential bacterial growth). Sanitize before use to
eliminate any potential microbiological contaminates

Pre-installation procedures as prescribed in this manual must be performed before installing
the WLH2 Classe.
Always install indoors and place the Waterlogic WLH2 Classe on a firm, flat and stable surface.
1. Attach the water supply line to the 1/4” feed water inlet bulkhead fitting on the upper
left section of the rear panel of the WLH2 Classe. Waterlogic requires the use of a water
pressure regulator. Water feed pressure must be between 40-60 psi.Turn on the water
supply and check for leaks.
2. Connect the upper right port to a food grade CO2gas supply, again using a 1/4" supply
line. Open the tap of the gas bottle and set the pressure to 4 bar (50psi).
3. Check to ensure that the Red Compressor Power Switch is the O=OFF position.
NOTE: Switches have internal LED that illuminates when placed in I=ON position.
4. Connect the power cord to the back of the Waterlogic WLH2 Classe and to a 120 Volt
supply. Turn Red Compressor Switch to the I=ON position to power the unit.
5. Water will begin filling the Ice Bath, which will take 4-5min. During this time the White
Power indicator on the front UI panel should be blinking, communicating the unit is
running its initial setup process.
6. Once the Ice bath has reached a suitable level (after 4-5min), the White Power indicator
will light solid, and water can now be dispensed. NOTE: There is a 5 min delay after the
indicator lights solid before the compressor begins to operate.
7. PLACE A CONTAINER IN THE DISPENSE ARE TO CATCH WATER. Dispense water from the
Still and Sparkling dispense spouts, one after the other, by holding in either the small or
large dispense button. For the Still dispense, nothing will come out for several seconds at
first, as the lines are being filled with water. Water should begin flowing after several
seconds. For the Sparkling dispense, the same process will occur, but there will also be
some CO2gas release during the first few seconds of dispensing as well. Continue
dispensing until a strong stream is achieved.

WLH2 Classe Manual Page 35 – Revision: 3-2-2021
8. Dispense about 1 gallon of water from each line. This will sufficiently FLUSH the lines. Be
sure to place a container under the spouts to collect the water from the flushing process.
9. If water supply is RO water (or if the TDS is less than 10ppm), a spoonful of sodium
bicarbonate (baking soda) MAY need to be added to the water in the ice bath to raise the
waters TDS to a level that the sensors can effectively operate in. NOTE: If TDS is too low,
compressor will not cycle on.
10. Verify that the UV Lamp operates as expected. The light can be seen from the underside
of the spout.
WARNING! ULTRAVIOLET RADIATION. Protect your skin and eyes against ultraviolet
rays. Never look directly at an operating UV light. Always disconnect before removal.
11. Move the Waterlogic WLH2 Classe into its final operating position. Be sure that a
minimum of 2” clearance is maintained around both sides and the back of the WLH2
Classe.
12. This is important to allow proper airflow and heat exchange of refrigeration system.
13. Be sure to lock the adjustable feet of the WLH2 Classe. Never install on an incline.
14. When the WLH2 Classe has reached its Cold Temp Set Point Temperature, the
compressor will cycle off.
15. Once the WLH2 Classe is at the target temperature, sample the water to ensure water
meets expectations and additional rinsing or adjustment is not required.
16. Check the WLH2 Classe for any leaks. External Leak Protection is always recommended.
17. After about 45min to an hour, dispense about ½ gallon of water from the Sparkling side
to rid the sparkling capsule of any lukewarm water. This will allow the Sparkling canister
to regenerate with chilled water, creating a higher quality of sparkling water.
18. At this time, the volumetric auto-dispense settings can be configured. See page 11.

DRAINING INSTRUCTIONS
WARNING! STORE UNIT EMPTY. ALWAYS SANITIZE BEFORE REUSE.
The unit must be completely drained and sealed before storing to avoid stagnation and
reduce microbial growth).
1. The WLH2 Classe has two main parts to drain, the Still/Sparkling water lines, and the Ice
Bath. Draining instructions for both parts are below.
2. First, SHUT OFF the water supply to the machine.
3. Close the valve on the CO2bottle.
4. To drain the WLH2 Classe Ice Bath, remove the 1/4” plug, that is inserted into the drain
bulkhead located on the rear of the machine. *Upon removal of the plug, water will
begin draining from the ice bath. Have a container prepared to catch the water, or back
the machine up to a sink or drain basin. This operation will take upwards of 20-30min
to fully drain the ice bath.
5. To drain the Still water line of the WLH2 Classe, (with the Gas Bottle shut off) disconnect
the gas line from the CO2inlet. Disconnect the water supply line from the water inlet of
the unit. Now plug the gas line into the water inlet of the unit and open the valve of the
Gas Bottle. Simply hold one of the Still Water dispense button to drive water out of the
still water line until it is empty, and gas is escaping. Shut off the valve of the Gas Bottle
and reconnect to the CO2inlet of the unit. Once reconnected, do the same for the
Sparkling Water line, holding the Sparkling dispense button until the dispense line is
empty, and it begins to gas.
6. Turn the Red Compressor Switch to the O=OFF position immediately after draining the
sparkling line.

ADJUSTING THE GAS BLEND
The gas blend for the Sparkling line can be adjusted if a sputtering or too much splash from the
Sparkling dispense is experienced.
1. Locate the gas blend adjustment underneath the dispense nozzle panel, between the
two nozzles.
2. Using a wide flathead screwdriver (NOT A PHILLIPS), turn the adjustment point
clockwise to dial back the gas or counter-clockwise to increase the gas blend. Adjust
until a smooth stream is achieved.
