(125oF) can cause severe burns or scalding. Keep unauthorized people and children away from the
unit to avoid accidental dispensing of hot water.
WARNING! CONNECT TO POTABLE WATER SUPPLY. This system is to be used for water only and is
not intended for use where water is microbiologically unsafe or with water of unknown quality
without adequate disinfection. System is designed for the supplemental bactericidal treatment of
public drinking water, or other drinking water, which has been tested and deemed acceptable for
human consumption by the state or local health agency having jurisdiction. The system is designed to
reduce normally occurring non-pathogenic or nuisance microorganisms only. System is not intended
for treatment of contaminated water.
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
CAUTION! INDOOR USE ONLY. Intended for household use only. Never expose to direct sunlight,
heat sources, or ambient air temperature above 37°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 27°C (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. Input or feed pressure must be 40 psi to 60 psi. Be
aware of any potential pressure surges caused by building/municipal pumping stations. 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 to minimize risk.
CAUTION! USE PROPER SUPPLY LINES AND FEED WITH POTABLE AMBIENT WATER ONLY.
Feed water over 37°C (100°F) may damage the treatment components. Always use supply lines with
adequate pressure rating and UV resistance. Close water supply valve and contact service
representative if a leak is noticed.

CUBE Manual Page 15 - Revision: 5-24-2017
All Waterlogic Hot Tanks have a built-in Vent or
properly.
HOT TANK PRINCIPLES OF OPERATION
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

HOT TANK DESCALING
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

FILTER REPLACEMENT
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 on 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.
WARNING! Read and understand the contents of this manual before attempting to service
CUBE. 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.

INSTALLATION 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 (EL-5001-A). 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 exposed to direct sunlight, heat sources, or ambient air
temperature above 97°F (3°6C) or below 50°F (10°C). 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 2inches. 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 STABLIIZED SUPPLY LINES. Feed the unit with a potable ambient or cold water
supply only. Feed water over 105° F (40° 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 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 and sanitization procedures as prescribed in this manual must be performed before
installing the CUBE Water Treatment System.

need to be flushed.
7. Turn off both the Red Power and the Green Heater / Compressor Switch’s.
O=OFF
NOTE: Switches have internal LED that illuminates when placed in I=ON
position.
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.
8. Select the Ambient Water Icon followed by the main dispensing button, dispense 10 liters of water.
This will remove excess carbon fines and sufficiently generate the filter.
9. Prime the Hot Tank. Holding a container under the dispensing faucet, press the hot button until it
lights up. While the hot water icon is lit, select and hold the central dispense button until a
continuous flow of water is obtained (this could take 2 to 4 minutes). Once a continuous flow is
obtained, flush 5 liters of water by continuing to hold the hot button. Hot Tank is now full.
10. Prime the Cold Circuit. Holding a container under the dispensing faucet, Select and hold the cold-
water icon until it lights up. While the cold-water icon is lit, select the central dispense button to
start filling the cold tank with water. After one minute, the machine will automatically un-select the
central dispense button. Repeat selection of the central dispense button until the cold tank has filled
and water is coming out of the faucet (this could take 2 to 4 minutes), press and hold the main
dispensing button until a continuous flow of water is obtained. Once a continuous flow is obtained,
release the dispensing button. Cold tanks are now full.
11. Prime the Ambient Circuit. Holding a container under the dispensing faucet, Select and hold the

minutes to chill.
14. Taste test the water, if there is any hint of taste in the water, flush and additional 1 ½ gallons of hot
water, then 1 ½ gallons of cold water. Do another taste test and if necessary repeat the flush again.
15. Verify that the UV Lamp operates as expected (no UV Lamp alarm will sound on the display).
WARNING! ULTRAVIOLET RADIATION. Protect your skin and eyes against ultraviolet rays.
Never look directly at an operating UV light. Always disconnect before removal.
16. Move the Waterlogic CUBE Water Treatment System into its final operating position. Be sure that a
minimum of 2” clearance is maintained around both the sides and the back of the unit. This is
important to allow proper airflow and heat exchange of refrigeration system.
17. When the unit has reached its Hot Temp Set Point, the heater will cycle off. When the unit has
reached its Cold Temp Set Point Temperature, the compressor will cycle off.
18. Once the unit is at the target temperature(s), sample the water to ensure water meets expectations

FILTER REPLACEMENT
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 on 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.
WARNING! Read and understand the contents of this manual before attempting to service
CUBE. 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.

HOT TANK DESCALING
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.
