SERVICE REQUIREMENTS
WARNING! Read and understand the contents of this manual before attempting to service
WL2FLT Water Treatment System. Failure to follow the instructions in this manual could
result in death, serious personal injury, or severe property damage. Only trained and
qualified technicians should attempt to install, maintain, or service Waterlogic Equipment.
1. Visually inspect all electrical and water connections for signs of wear or damage.
DANGER! HIGH VOLTAGE ELECTRICAL HAZARD. Unplug before inspection and service.
2. Waterlogic recommends changing the UV Lamp every 6 months.
WARNING! UV-C EMITTER (UV LAMP). This appliance contains a UV-C emitter (UV Lamp).
UV-C radiation may, even in little doses, cause harm to the eyes and skin. Unintended use or
damage to the housing may result in the escape of dangerous UV-C radiation. Never operate
the UV-C emitter if damaged or removed from enclosure. Do not touch or look directly into the
faucet.
CAUTION! UV LAMPS ARE HAZARDOUS. Lamps are considered Hazardous Waste and must
be disposed of accordingly. Refer to Product MSDS sheet for details.
3. Clean the Quartz Spiral that surrounds the UV Lamp with a non-abrasive cloth, descaling solution,
or ultrasonic bath if needed when changing UV Lamps.
CAUTION! UV SYSTEM IS FRAGILE. Never handle the UV lamp or Quartz Spiral with bare
hands. UV Lamp and quartz spiral must be free of oils and contaminants to ensure proper
operation. Use a soft non-abrasive cloth to clean.
4. Sanitize the Cold Tank per instructions in the pre-installation procedures.
5. Clean and sanitize external surfaces of the unit. Use soap and water or chemicals that are
compatible with ABS plastic and will not damage or degrade the product surfaces.
6. Remove and clean the Faucet. Replace as needed.
WARNING! SANITIZER MAY CONTAIN HAZARDOUS CHEMICALS. Use of proper personal
protective equipment such as rubber gloves and eye protection is required.

WL2FLT Manual Page 14 – Revision 7-19-21
HOT TANK PRINCIPLES OF OPERATION
All Waterlogic Hot Tanks have a built-in Vent or
Expansion Chamber in the top of the tank except for
WL270 (GF) units.
The Vent Chamber allows for expansion of the water
when it is heated.
The chambers are separated by a welded-in tank
baffle.
Water always flows into the bottom of the tank and
out the top to the faucet.
The hot tank outlet tube has a restrictor in its base.
This ensures the reservoir is always full by allowing
more water in than out.
There is a small hole in the side of the tank outlet tube
that allows air and water to pass into the vent
chamber as it is heated.
Water in the vent chamber is suctioned back through
the outlet tube vent hole when water is dispensed.
Expansion of water as it is heated in the reservoir will
push the water out the faucet when the outlet tube
vent hole becomes plugged with debris or scale.
The small Outlet Vent Hole is susceptible to scale build
up and is a key indicator that descaling is required.
It is critical to descale the hot tank through the vent
line and outlet line on a regular basis to prevent this
problem.
Descaling through the inlet and/or outlet lines only
will not clean the vent chamber and outlet vent hole
properly.

WL2FLT Manual Page 16 – Revision 7-19-21
HOT TANK DESCALING INSTRUCTIONS
The Hot Tank requires removal of mineral deposits (descaling) on a regular basis. Typically
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 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 are non-toxic but left unattended will hinder your
unit’s performance.
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.
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
•19 Liter (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
1. Put descaler per directions and 3 drops of food coloring into the descaling cartridge.
2. Connect descaling cartridge to the inlet water supply and connect to Inlet Bulkhead Fitting on the
back of the WL2FLT Water Treatment System. Turn on Water Supply.
3. Select Hot Water and depress the Main Dispensing Button on the Front Control Panel until
descaling solution (colored water) comes out of the faucet. Container and drain basic will be
required to catch water from the faucet.
4. Turn off water supply and remove sanitizing cartridge from inlet water supply. Reconnect water
supply to inlet fitting.

WL2FLT Manual Page 17 – Revision 7-19-21
5. Allow descaling solution to remain in the Hot Tank for 15 minutes (length of time may vary
depending on water conditions).
6. Place a pitcher, catch basin or other container under the faucet of the WL2FLT Water Treatment
System.
7. Flush the Hot Tank by dispensing hot water until water runs clear.
8. Once clear Water dispenses from the faucet the Hot Tank has been descaled. Always ensure the
WL2FLT Water Treatment System is performing to the customer’s satisfaction.
WARNING! HOT WATER. The WL2FLT Water Treatment System produces Hot Water up to
86°C (187°F). Water above 52°C (125°F) can cause severe burns or scalding. Hot water should
be dispensed carefully into insulated container to avoid injury.
CAUTION!MUST REPLACE HOT TANK 3-5 YEARS DEPENDING ON USAGE. The Hot Tank and
its controls must be replaced a minimum of every three to five years to ensure efficient and
dependable operation.
WARNING! REINSTALL ALL PANELS AND COVERS. Always reinstall all Panels, Protective
Covers, and Fasteners after servicing equipment. Failure to do so could result in severe
personal injury and will void the certifications and warranty of the equipment.

ADJUSTING COLD SET POINT
Cold Water Temperature – Factory Set Point is 41°F (5°C) and can be adjusted to 34°F - 54°F (1.1°C to
12.2°C)
The cold set point can be adjusted by accessing the cold
thermostat adjustment screw under the decal at the rear of the
unit.
Remove the red portion of the Cold Tank Temperature label to
access the adjustment screw.
The factory set point is ~41°F and is indicated by the dot on
sheet metal.
Turning the adjustment screw clockwise to lower the set point
temperature.
Do not adjust past the “Max Cold” position at 3:00 position to
avoid freezing the cold tank.
Turning the adjustment screw counter-clockwise to raise the set
point temperature.

PROGRAMMING INSTRUCTIONS
DISABLING ENERGY SAVING SLEEP MODE
All WL2FLT Water Treatment Systems come from the factory with Energy Saving Sleep Mode
engaged to meet the Energy Star Certification requirements. Energy Saving Sleep Mode disables
the heater circuit if the unit has not been used for a continuous 3 hour or longer period.
Selecting any button "wakes up" the WL2FLT Water Treatment System and turns the heater
circuit back on. The hot tank will typically take less than 10 minutes to heat the water from
ambient to the 85°C (185°F) set point.
Unplug Power Cord and remove Top Cover to access back side of the Display PCB.
WL2FLT Water Treatment Systems comes with the
Energy Saving Sleep Mode “ON” - the Default Position.
DIP 1 in the "ON" position (up).
Deactivate the Energy Saving Sleep Mode by moving
DIP 1 in the "OFF" position (down).
