Congratulations on your purchase!
Thank you for choosing HOSHIZAKI MODwater
TM
model DWM-20A.
The DWM-20A has the following main characteristics and features:
Multiple Options: From the left to the right: chilled sparkling water, chilled still water, hot water and cold alkaline water.
Fast: It fills bottles in seconds.
Child Safe: Avoids accidental dispensing of hot water (by enabling the Child Safety Switch).
Energy Saving: It enters stand-by mode – with button lights off, if not frequently used.
Thermal Energy Saving Switch: Turn the hot water power off if not used daily.
Alkaline Chamber: Mineral chamber included inside the dispenser.
IN ORDER TO INSTALL DWM-20A DISPENSER, YOU NEED:
1. Installation Kit: (included) a set of items for proper installation of this dispenser (see page 6).
2. Carbon Dioxide Tank (Not included): external to this dispenser (see page 8).
NOTICE
• Read the instructions in this Manual and retain for future reference.
• Product failure due to improper installation is NOT covered by the Warranty.
• The DWM-20A is for indoor use only. Do not install it outdoors.
• Due to rigorous testing performed by the Manufacturer on each of its products, the DWM-20A may
contain reasonable traces of liquid sanitizing solution inside.
• SLEEP MODE. After one hour of inactivity, DWM-20A enters SLEEP MODE to reduce energy
consumption, and all 4 touch buttons are off. To wake it up, just touch and release your finger on any of
the four buttons.
• SAFETY MODE. The green and red LED indicators are both blinking while all touch buttons are off. To
prevent accidental dispensing the DWM-20A automatically stops if more than 0.4 gallon (i.e. 1.5L) of
water is dispensed continuously, or if a button is touched for more than 30 seconds without pausing. It
also stops if there is little or no water in the pipeline flowing to the DWM-20A, or there is an internal leak.
To restart it, switch main power off and, after just 3 seconds, turn it on again.
• ENERGY SAVING. DON’T NEED HOT WATER OFTEN? Turn Hot Water Switch (RED) off and enable
Child Safety Switch (turn it to the “YES” position). Otherwise, if you don’t dispense hot water at least once
per month, the DWM-20A automatically switches hot water power off, to save energy. To get hot water
again, just touch and hold the red touch button for 15 seconds.

4. Do not place the DWM-20A, its electric cord, or plug on or near stoves or other hot surfaces.
5. Always unplug the electric power cord when the DWM-20A is not in use for an extended period, when it is relocated,
or before cleaning it.
6. Leave at least a 4-inch gap on all lateral sides between the DWM-20A and the wall to assure sufficient air circulation
for proper ventilation and efficient cooling of the water dispenser’s refrigeration system. Do not install the DWM-
20A inside a cabinet because without proper air-circulation the water dispenser’s refrigeration system will fail.
Alternative installation solutions are possible: refer to www.hoshizakiamerica.com
to find out more.
7. Children and people with mental disabilities must be supervised by a person who is responsible for their safety
when using the DWM-20A, because it can dispense water at a very high temperature. ADULT SUPERVISION
REQUIRED.
8. To avoid potential hazards and personal injury, never attempt to open/disassemble the DWM-20A by unscrewing
panels/covers: there are no user-serviceable parts inside! In case of malfunction, call the Manufacturer using the
toll-free customer service line. Repairs of DWM-20A must only be performed by the Manufacturer or its qualified
service personnel to avoid potential hazard and electric shocks. The Manufacturer warranty will be automatically
invalidated if non-authorized personnel service the DWM-20A. Call toll-free at 1 (800) 233-1940.
9. Any use of non-original parts (i.e. parts not provided by the Manufacturer), including third-party parts, could lead
to a permanent malfunction or a failure of the DWM-20A, property damage and/or personal injury, including death.
10. Using third-party filters or other filtration systems for the DWM-20A water dispenser other than original filters may
result in a permanent malfunction of the dispenser and may also cause personal injury. Furthermore, it will
invalidate the manufacturing warranty on the DWM-20A.
11. If any component of the DWM-20A is misused or used incorrectly, the water dispenser may fail and cause property
damage and personal injury, including death from electric shock. Misuse of the DWM-20A may cause deterioration
of the quality or contamination of the materials used in the DWM-20A. Connecting the water dispenser to a supply
of contaminated water may result in serious personal injury. Only connect the DWM-20A, through its own external
filtration system, to a potable water supply.
12. Water pipe connections and fixtures directly connected to a potable water supply shall be seized, installed, and
maintained in accordance with federal, state, and local codes.

10
Instructions
1. Make certain that installation of the DWM-20A model complies with all federal, state and local laws and regulations
as well as with your building codes, office/apartment or condo provisions, rules or regulations.
2. In the installation of DWM-20A you must only use HS-5441 filtration system. The Manufacturer is not responsible
for any misuse or modification of HS-5441 filtration system and accepts NO liabilities if the DWM-20A is used with
different filtration systems. In addition, the use of non original filters invalidates the Manufacturer
3. on the DWM-20A water dispenser.
4. Do not connect the DWM-20A dispenser and its filtration system to a water supply that is microbiologically unsafe
or of unknown quality without adequate pre-treatment and disinfection. Connect HS-5441 filtration system to the
city potable water only.
5. If the DWM-20A is left unused for more than 3 days, dispense at least one bottle of water from each water type. If
left unattended for more than 30 days, replacement of its filtration system and of its alkaline chamber is
recommended before starting to use the DWM-20A again.
6. The DWM-20A dispenser must be connected to a cold water supply with a pressure of at least 45 psi measured
on a 3/8” section tube. A very low external water pressure (at or below 40 psi) or a very low water flow rate (below
1 gallon/minute) will significantly reduce or hamper the performance of the DWM-20A and its ability to properly
carbonated sparkling water. If the water pressure is low, please use the booster pump as indicated in the Parts
Manual (order separately).
7. The DWM-20A is designed to operate up to the maximum allowed water pressure for a residence or a commercial
building, which is 80 psi (552 kPa). However, the recommended maximum water pressure is 60-65 psi. To reduce
the water pressure, use the water pressure regulator provided in the installation kit.
8. Do not use the DWM-20A outdoors. The recommended room temperature, for indoor use, is comprised between
41°F and 90°F.
9. When the filtration system indicator (green light – top right) starts blinking (on/off) it means that the HS-5441 filters
and the HS-5442 alkaline chamber have reached the end of their lifespan, and MUST be changed in order to
prevent quality deterioration of your drinking water and/or clogging of the system. It is recommended to replace
the HS-5441 filters and the HS-5442 alkaline chamber as soon as possible when the green light indicator starts
blinking or every 6 months, whichever comes first.
DUE TO THE FACT THAT THE MANUFACTURER MAY NOT KNOW THE QUALITY AND THE
PERFORMANCE CHARACTERISITCS OF ANY POSSIBLE ALTERNATIVE FILTRATION SYSTEMS IN THE
MARKET, PLEASE NOTE THAT THE MANUFACTURING WARRANTY OF THIS DISPENSER BECOMES
NULL AND VOID SHOULD YOU USE FILTER(S) OTHER THAN THE HS-5441.

General Instructions:
• The DWM-20A model is designed to be located on any countertop, or on a Hoshizaki C-80/AM-50 ice maker as
indicated on the following section (see page 23).
• In case of installation on a counter, the DWM-20A must be placed on a sturdy, uniform surface capable of
withstanding, at least, 93 lb. of weight. A kitchen countertop is an ideal place. Unpack the DWM-20A model and
place it on a counter, next to an electrical power outlet, exactly where it is supposed to be permanently installed.
• Locate a water line within 10 feet of the DWM-20A. Make sure the water supply you intend to connect the DWM-
20A to is cold and is not coming from a water heater or boiler.
• Allow 4" of space at rear and sides of DWM-20A for better ventilation. Never place the DWM-20A inside a closed
cabinet without proper ventilation. In case this requisite may not be fulfilled, go on www.hoshizakiamerica.com
web site for alternative installation solutions.
• IMPORTANT: Before beginning the installation process, insert the alkaline chamber (K) by unscrewing the lateral
panel of the DWM-20A. Refer to diagrams on pages 36 and 37 for details about how to perform this operation.
• The All-in-One filtration system (included) and the CO
2
gas tank (not included) should be installed under the
counter.
• In order to connect the dispenser to its external filtration system (with the 3/8” flexible plastic tube provided in the
installation kit) and to the CO
2

• IMPORTANT: connect the drain pan. The drain pan comes connected to a drain pipe that runs underneath the
dispenser and can be connected to a drain by a flexible plastic tube connected to the back of the DWM-20A
dispenser. If there is not enough downward slope for the drain line, please install an accessory drain pump to
ensure water does not back-up in the drain line. Remove the two (2) black rubber plugs at the bottom of the
drain pan and at the end of the drain tube.
• Alternatively, if the location where the dispenser is installed has no drain, you can go “drainless” and use the
drain pan as a “drip tray.” You must detach the metal pipe underneath the drain pan (by pushing down the silicon
connector) and leave the plug at the bottom of the drain pan. The drain pan must be emptied periodically, or
when it is full. NOTE: Please be sure not to pour non-water liquids in the drain pan as they can create unsanitary
conditions.
• The DWM-20A drain pan can be connected to a drain through a flexible plastic tube (1/2”) as per picture (not
included).

3. Next, install the “Angle Stop Valve” (C), as shown, (fig 3).
4. Locate the 3/8” flexible tube in the installation kit. Cut a short tube section to
connect the angle stop valve to the other components of the installation kit, (fig 4).
Then install the “ASSE 1032” backflow prevention valve (I), the water pressure
regulator (B) and the shutoff valve (A).
※Install (C), (I) and (B) close to each other. Install (A) close to the DWM-20A on
the countertop. Make sure (C) is installed on the cold water source under the sink,
NOT the hot water source which is often located next to the cold! Insert the other
extremity of the 3/8” tube in the elbow quick-connector in the “WATER INLET” port
located at the back of the DWM-20A. IMPORTANT: open both valves (C) and (A)
so that water from the temporary water line can enter the DWM-20A.
5. TIP: To connect the 3/8” flexible plastic tube to the other components of the
installation kit, simply push the tube into the quick-connect fitting until it stops. Then
pull out the tube to check if it is secured in its position and it is properly connected.
To disconnect it, first push in the collet as shown in the fig 5. Next, with the collet
held in position, remove the tube by pulling it away from the collet as shown.
WARNING: AS DIRECTED IN THE INTERNATIONAL PLUMBING CODE OF THE INTERNATIONAL CODE
COUNCIL AND THE FOOD CODE MANUAL OF THE FOOD AND DRUG ADMINISTRATION (FDA), THIS
DISPENSER MUST BE INSTALLED WITH ADEQUATE BACKFLOW PREVENTION TO COMPLY WITH FEDERAL,
STATE AND LOCAL CODES. FOR MODELS INSTALLED OUTSIDE THE U.S.A., YOU MUST COMPLY WITH THE
APPLICABLE PLUMBING/SANITATION CODE IN YOUR AREA.

18
• Locate the gas tubing (1/4”) as found in the installation kit.
• Attach a CO
2
regulator (as provided in the installation kit) to the external CO
2
canister (not provided) by turning the
nut to the right while holding the regulator. IMPORTANT: Ensure that the main valve on the external CO2 canister
is completely closed.
• Connect the CO
2
regulator using the 1/4” CO
2
tube, to the elbow quick connector (1/4”) in the “CO
2
INLET” at the
back of the DWM-20A appliance.
• Open the main valve on the external CO
2
canister very gently to avoid fast release of gas.
• Then, use the CO
2
regulator (see installation kit) to adjust the pressure. Turn the blue handle knob located on the
front side of the CO
2
regulator. Set the pressure to your desired fizziness level (typically around 55 to 65 psi). After
the pressure is set, push the blue knob in, to lock the arrow right at the selected gas pressure.
• See Figure 6 below. For fine tuning go on page 29.
WARNING: THE CO
2
TANK MUST BE SECURED WITH A CHAIN OR RESTRAINT (P) IN AN UPRIGHT POSITION
AS INDICATED ON PAGE 14 OF THIS MANUAL.
• At this point, locate the main electrical power socket and the main electrical power supply switch at the back of
the DWM-20A, plug in the dispenser and switch the main electrical power ON (see fig 7 and fig 8 below).
IMPORTANT: do not turn on hot water power yet (the red switch behind the DWM-20A).
IMPORTANT: if the DWM-20A was NOT transported upright, make sure the DWM-20A has sat still in its position
for at least 2 hours before turning on main power. This is to ensure the refrigerant has had time to settle.

• With power on, after one (1) minute, two touch button lights - the green-sparkling and the white-alkaline - will
start blinking. Touch and hold both of them – contemporarily – for three (3) seconds, until ALL all four button
lights (green, blue, red, and white) will start blinking, indicating water is flowing into the dispenser.
• If valves (A) and (C) are both opened, the flow of water inside the DWM-20A will be audible, which indicates the
automatic filling of the refrigeration system has been activated. This automatic filling process of the internal
chiller of the unit may take up to ten (10) minutes. Wait. IMPORTANT: When the water dispenser is ready, all
the touch button lights will stop blinking and stay illuminated.
• The unit’s compressor starts after another five (5) minutes. Check the air temperature behind the dispenser’s
grid. The air blowing through the grid should be warm (red circle area in the picture on page 16).
• Touch the Alkaline button (white) and dispense alkaline water. Initially, the alkaline water may be gray in color
because of the granular activated carbon contained in the alkaline chamber. After completely flushing the
alkaline chamber HS-5442, the alkaline water dispensed is clear and transparent.
• Touch and hold the red-hot touch button until water comes out from the hot water nozzle (located just behind the
main nozzle). Please note that the nozzle for the hot water is separated from the nozzle of alkaline, chilled and
sparkling water in order to minimize splashes and to reduce flow rate (for safety reasons). If by touching the red
button hot water is not dispensed, it is probably due to the Child Safety Switch located at the back of the
dispenser being switched on (i.e. the switch is positioned on its “YES” position). The Child Safety Switch will
prevent children from accidentally dispensing hot water by pressing the red button. Therefore, disabling the Child
Safety Switch will allow you to dispense hot water by touching the red button. This will also activate the red-light
indicator “HOT WATER” located at the right corner of the front of the dispenser. When the red light is illuminated
- WARNING sign - the DWM-20A is enabled to dispense hot water. In order to dispense hot water, first the
internal HOT WATER TANK MUST BE FILLED UP: touch the red button until the hot water tank is totally filled
and water starts flowing out of the nozzle.
• Next turn on the hot water switch (red switch) located behind the DWM-20A model (see fig 8). It takes almost ten
(10) minutes for the water in the internal hot water tank to reach the maximum temperature.
• Now dispense some Chilled and Sparkling (even without adjusting the CO
2
gas for optimal carbonation level),
and check if the dispenser is working properly. IMPORTANT: for fine tuning of the dispenser, wait unit the
installation is completed and the water is very cold. If the water is not cold enough, carbonation will not occur!
• At this time, while the dispenser has started and its refrigeration and heating systems are working, you might
need to drill a 3/4" hole on the countertop in proximity of the back of dispenser to connect the DWM-20A unit with
its filtration system and its CO
2
tank. Use a one-piece hole saw or equivalent tool.
• At this point, close the Angle Stop Valve (C), and dispense some alkaline water for 5 seconds in order to release
the water pressure inside the temporary water line.
• Shut off the valve (A) behind the Water dispenser but KEEP the electrical power on. Now you can remove the
temporary water line.
• Leave the water dispenser powered on so that its refrigeration system can work during the time the filtration
system is installed. Then, when the installation is completed, you can easily check the temperature of the chilled
water and the carbonation of the sparkling water. IMPORTANT: Do not move the water dispenser since its
refrigeration system is now full of water and might overflow. If you need to slightly move the DWM-20A to its final
position, pay extreme attention. The dispenser is quite heavy now (93lbs), its refrigeration is full of water and
any sudden movement might produce an internal water overflow and small flooding on the countertop. Avoid
this. Do not ever incline the DWM-20A.
• Install the leak detector tee (D) close to the water pressure regulator (B). Do not activate leak detector by
inserting its alkaline battery until the installation is complete.
• Connect (D) & (F) (i.e. the 3/8” 2-way divider), which is the inlet of the two All-in-One filters HS-5441. The two
filters shall be connected “in parallel”. Connect the temporary line from the other 3/8” 2-way divider (the outlet
port of the double All-in-One filters) directly to the sink to allow flushing of the filters. Open the angle stop valve
(C) and keep it open until clear water is dispensed through this temporary line. IMPORTANT: the complete
flushing of the external filters may require up to five (5) gallon of water to pass through.

20
• When completely clear water is dispensed through the double All-in-One filters, close the angle stop valve (C)
again, and remove the temporary water line.
• Run a line from the back of the dispenser to the 3/8” 2-way divider which is connected to the filters’ outlet port.
• Now that the entire water line is connected, as per the picture on the next page, open the angle stop valve (C)
and also the shutoff valve (A).
• IMPORTANT: make sure DWM-20A is fully connected to the water line and to the CO
2
line and dispense some
water from DWM-20A. Now pull all the lines: the 3/8” water inlet line, the 1/4” CO
2
gas line and, also, the 1/2”
water drain line, if present) in order to check if they are all properly connected with the various John Guest
connectors. Make sure there are no leaks. Insert collect locking clips 1/4” and 3/8” as appropriate at any junction.
• Insert the battery (included) into the water leak detector. Use a small piece of wet fabric or wet paper towel in
order to test the leak detector by using the wet fabric or paper towel to touch both electrodes and close the
circuit. Check that the leak detector gets triggered correctly by listening for a loud beep. To reset the leak
detector, press and hold its reset button for five (5) seconds until the water solenoid valve of the leak detector
opens.
• Make sure that the entire installation area is clean and dry. Cut a small square of (completely dry) paper towel,
fold it and position the paper towel under the electrodes of the leak detector: if the paper towel gets wet due to a
flooding, the leak detector will activate and the solenoid valve will close the water line. Then the leak detector will

21
start beeping loudly. However, thanks to the paper towel wrapped around, a small spill from a glass of water or
from the drain pan would not be sufficient to trigger the leak detector.
• Carefully position the leak detector under the counter, close to the double All-in-One filters, or in an area where
potential flooded water would naturally accumulate, (see diagram below).
• Now the installation is complete, and it is time for setup and fine tuning. Place a bottle or container on the drain
pan. Dispense alkaline water (white button) until the dispensed water is clear of carbon particles. NOTE: It is
normal that the first two gallon of mineralized alkaline water appears black or milky in color. Wait 10 minutes.
Dispense two gallons more until the water is completely clear. Repeat the process after waiting another 10
minutes until the alkaline water is totally transparent.
• Dispense 16 oz. of chilled (still) water (blue button). If the DWM-20A has been turned on for more than one hour,
the chilled water now should be ice-cold.
• Next, dispense 16 oz. of sparkling water (green button). Make sure the regulator has the arrow in the green
region (see fig 6 on page 18). For fine tuning of the carbonation level, refer to the table on page 29.
• Next, dispense hot water (red button). Check if the red LED light top left is on. If the hot water tank heater has
been on for more than 10 minutes, the hot water now should be boiling-hot.

9. Repeat step 6, 7 and 8 above for a second time.
10. Empty all the sanitizing solution from the hot water tank by using the drain line.
11. Begin dispensing water from the hot water line. This will fill the Hot water Tank with water. Empty the hot tank
from the drain line and repeat this process twice to ensure that all the sanitizing solution is out.

39
Electrical System
The DWM-20A dispenser must be plugged directly into 110/120 VAC, 60Hz wall outlet only (15 Amps). A 15A –
125VAC / 250VAC circuit breaker is installed on the dispenser and the circuit breaker can be accessed for reset at
the back of the dispenser (i.e. Power Reset Button).
IMPORTANT: In case of breaker trip, only reset once. If it happens again shortly after, send the water dispenser back
to the Manufacturer for maintenance.

40
Transporting and Relocating
If the DWM-20A dispenser needs to be relocated to another place or sent back to the manufacturer or the dealer for
repairs, it is necessary that the water inside the hot water tank and the refrigeration system is drained. Please follow
the below procedures:
1. Close the CO2 supply line by turning the handle knob (turn clockwise) on the CO2 tank’s regulator.
2. Dispense sparkling water (green button) to make sure that sparkling water comes out totally flat (no gas).
3. Close the water supply line and turn the shut-off valve located right behind the dispenser to the “off” position.
4. Dispense alkaline water (white button) until no more water is dispensed from the dispenser.
NOTE: DO NOT dispense chilled water (blue button).
5. Turn the Main Power switch to its “off” position. The main power switch is located on the back of the dispenser.
Leave the dispenser disconnected for 24 hours to defrost its refrigeration system.
6. After 24h or more, proceed with de-installation. Unplug the power cord from the back of the dispenser.
7. Unplug the CO2 tube (1/4” tube) on the back of the dispenser.
8. Unplug the “WATER INLET” tube (3/8” tube) on the back of the dispenser.
9. Locate the “Cold Drain” and “Hot Drain” on the back of the dispenser. Remove the plug from the “Cold Drain” to
drain the water from the dispenser’s refrigeration system and drain into a bucket or container. These will be
about 2 gallons of water. IMPORTANT: Use a five-gallon minimum container to collect the water drained from
the dispenser.
10. Next, repeat the process for “Hot Drain”. WARNING: Water from “Hot Drain” may still be hot, even after 24
hours.
11. Put the plugs back into the “Cold Drain” and “Hot Drain”. The DWM-20A dispenser is now ready to be
transported. Package the dispenser carefully, as its stainless steel external surfaces might be easily damaged
during transportation.
12. In case of swap-out between two DWM-20A, remember to also change both the filters (HS-5441), and the
alkaline chamber (HS-5442).

TECHNICAL SUPPORT
Troubleshooting
A. Lights are off
Check that the dispenser is NOT in its “SLEEP MODE”.
If the green dot light indicator (top right of the front
plate) is illuminated, the dispenser is simply “sleeping”.
Touch any button for a few seconds to start it and all
buttons will illuminate. If ALL lights are off (including
the two LED indicators at the top right of the touch
panel), check the main power cord connection: if
plugged in, check main power switch. If the dispenser is
connected to a power source, and if the main power
switch is on, press the power reset button once or
twice. The power reset button is located at the back of
the dispenser, just below the main power switch and is
indicated with the letters “PR” (i.e. Power Reset).
B. Both the green & red LED indicators are blinking,
while all four (4) touch buttons are off and no water can
be dispensed
The DWM-20A has entered “SAFETY MODE”. There
is no water in the supply tubing or the water pressure is
too low. Or somebody has operated the unit
dispensing more than 1.5 liters without pausing, or for
more than 30 seconds without pausing. If the issue is
no water, make sure water supply valve is open or, to
address low water pressure, replace filters or use
booster pump to increase water pressure. Once the
issue is solved, turn off the unit and after three seconds
turn it on again. If the issue is solved, the unit will
restart normally.
If it persists call 1 (800) 233-1940 for help.
C. There is an audible beeping sound
A leak detector is activated. In that case, proceed as
per instructions (see page 43) and reset the leak
detector to work.
D. Sparkling & Alkaline touch buttons are blinking
Indicates that the refrigeration system must be filled up.
Touch and hold both buttons contemporarily for three
seconds until ALL the buttons are blinking. Wait until all
buttons stop blinking and are solid. Now the dispenser
should be able to operate. Make sure there is water in
your pipeline flowing to the dispenser. If not, check your
water line; perhaps you need to open the shutoff valve
located at the back of the dispenser or the main shutoff
valve at your location.
E. All four (4) touch button lights are blinking
Indicates that the refrigeration system is being filled
with water. You should be able to hear it. If not, check
the water line; perhaps you need to open the shutoff
valve located at the back of the dispenser or the main
water valve at your location. If there is water in your
pipeline this operation lasts five (5) to ten (10) minutes.

42
F. Does not dispense hot water at all
“Child Safety Switch” is on its “YES” position (i.e.
down), indicating that child safety switch has been
enabled. To allow hot water to be dispensed, turn the
“Child Safety Switch” at the back of DWM-20A to its
“NO” position (turn it up). The red LED dot indicator on
the touch panel of DWM-20A should turn on.
G. Hot water is not hot
Check if the hot water power is on (red switch on the
back). If not on, turn it on (up) and wait ten (10)
minutes for the water to reach its maximum
temperature.
H. Hot water touch button (red) is off. All other buttons
are on.
The DWM-20A entered “ENERGY SAVING” and
automatically disconnected the hot water tank because
it was not used for an entire month. Push and hold the
hot water button (red) for 15 seconds: the button’s red
light will be on again and hot water will start coming out.
I. Does not dispense water at all, even when pushing
the Alkaline option (white button)
There is no water in your pipeline, Check the main
water supply connection and all the shutoff valves.
J. Sparkling water comes out flat, or no carbonated
enough
Check the CO2 tank: the “Capacity Gage” might be in
the red region. If it is in the red region, replace tank.
Otherwise, if the tank is full, adjust pressure to
necessary levels using CO2 regulator: arrow must be in
between 50 and 65 psi. If gas pressure is high while
water is dispensed totally flat, turn the knob on the gas
regulator anticlockwise (i.e. close it). Then release
pressure by cutting the gas tube (see fig 6 on page 18).
K. Green light indicator is blinking
The DWM-20A dispenser requires 2 new filters and a
new alkaline chamber. Call 1 (800) 233-1940. After
replacing the filters and the alkaline chamber, push and
hold for 5 seconds the Filter Reset button (indicated
with the words “FR”) at the back of the DWM-20A, until
the green LED indicator turns solid green back again.
L. None of the above
