CUBE Operating, Installation, and Service Manual Page 9 - Revision: 6-23-2015
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

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.

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.
Always install indoors and place the Waterlogic CUBE on a firm, flat and stable surface.
CUBE Operating, Installation, and Service Manual Page 25 - Revision: 6-23-2015
1. Attach the water supply line to the 1/4” feed water inlet bulkhead fitting on the back of the unit.
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 all of the connections for leaks.
2. Connect the power cord to the back of the Waterlogic CUBE and to a 120 Volt supply.
3. Turn the Red Power Switch to I=ON position.
4. The unit will now run through a self-test cycle. Once the self-test cycle has
completed the icon will stop flashing.
5. Place a container in the dispense area for flushing process. The filter will
now need to be flushed.
6. Check to ensure that both the red and green power switches are in the
O=OFF position.
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.
7. 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.
8. 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.
CUBE Operating, Installation, and Service Manual Page 26 - Revision: 6-23-2015
9. 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.
10. Prime the Ambient Circuit. Holding a container under the dispensing faucet, Select and hold the
Ambient water icon until it lights up. While the Ambient water icon is lit, select the central dispense
button to start filling the Ambient line with water (this could take 10 – 20 seconds). Continue to
dispense 15-20 fluid ounces more of water through the ambient option.
11. Turn on the Green Heater/ Compressor switch at the rear of the machine.
12. The Cube will now begin to heat / chill the water. The hot water should be up to operating
temperature after 8 to 10 minutes and the old water will take between 60 to 90 minutes to chill.
13. 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.
14. 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.
15. Move the Waterlogic CUBE 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.
16. 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.
17. Once the unit is at the target temperature(s), sample the water to ensure water meets expectations
and additional rinsing or adjustment is not required.
18. Check the unit for any leaks. External Leak Protection is always recommended.

REPLACING THE FILTER
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

DESCALING the HOT TANK
1. 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

Note: The Waterlogic Firewall reduces 7-log of waterborne bacteria, 5-log of viruses, and 4-log of
parasites potentially found in the drinking water. A small amount (about 2-ounces) of water remains in
the Firewall device after dispensing. This water does not remain permanently chilled, and will
eventually become room temperature after several hours. To ensure the next glass of water dispensed
is adequately chilled, Waterlogic recommends dispensing one 5-ounce or more cup of water after long
periods of inactivity. The first 2-ounces will be near room temperature, and the remaining 3+ ounces
will be very cold. The mixture of these two temperatures will provide for an adequately refreshing, cold
drink.
