Ozone Summary
The Ozone generator turns on 12 hours aer the last dispense and runs for 5 minutes every
day by default. The unit will let you know this by displaying a message, Acvated Oxygen on
and lighng up the Acvated Oxygen led during the sanizing process. This system is used to
sanize the water in the cold tank. There are four main components in this system:
1. Air pump- Provides air to the O-Zone generator. This is located next to the control board,
behind the right panel.
2. Air Filter- filters the air going to the O-Zone generator. This is located behind the cold tank on
the right side.
3. O-Zone generator- makes o-zone. This is located above the air filter.
4. Diffuser Stone- Diffuses o-zone into the water. This is located in the cold tank.

Programing the Ozone
PW90
The unit comes pre-programed from the factory at 5 minutes and should not need to be programed. But
depending on your customer you may want to change programing to suit their needs. The PW90 Ozone sengs
can be adjusted with the PW90 app, or on the display panel on the unit itself. NOTE: If the Ozone sengs are too
high, it can affect the taste and odor of the water.
PW90 Display panel:
1. Enter program mode.
2. Wave hand over the Hot buon unl the cursor is resng on “Oxygen Injecon”
3. Wave hand over the Dispense buon to select “Oxygen injecon”
4. While in the “Oxygen injecon” mode wave hand over the Hot buon to scroll through opons and Dispense
buon to make changes.
5. For example, please review illustraon below: - To adjust the on me, wave hand over the Dispense buon while
the cursor is blinking over “On me” unl the desired me is selected
•To adjust the air purge me, wave hand over Hot buon unl “PAO me” is blinking, wave hand over
Dispense buon unl desired me is selected
•To adjust the interval/off me, wave your hand over Hot buon unl “off me” is blinking, wave hand over
dispense buon unl desired me is selected
•To adjust to acvate at me of dispense, wave hand over Hot buon unl “At dispense” is selected.
Wave hand over Dispense buon unl desired me is selected

Programing the Ozone
PW90 CT
If changing the programing on the PW90CT is deemed necessary, it can be done Via Dip switch se�ngs on the
main board. Please see dip switch chart below.
NOTE: If the Ozone se�ngs are too high, it can affect the taste and odor of the water.

Installation
1. The water cooler must be installed indoors.
2. The water inlet is a ¼” quick connect water inlet located on the rear right bottom corner.
3. Place the cooler so that it is not in the way of traffic and leave two inches behind it so it has proper ventilation.
4. Coil the power cord and waterline behind the cooler.
5. This water cooler does not need a drain unless an RO system is being used for filtration. If a drip tray drain is needed,
part number “DrainKit” can be ordered. This is a drain designed to connect to the back side of the top front panel so the
drip tray can drain efficiently.
NOTE: please refer to local plumbing codes when connecting the Drip tray, or RO filters to a drain.
6. Filters need to be flushed at this point. Please see filter flushing instructions.
NOTE: leave the hot tank switch in the off position until the hot tank is full of water.
7. The filter settings should be pre-set from the factory, but if changes are needed, you can turn filters on or off, and
program filter life into unit.
PW90 Display Panel:
1. Enter the program mode.
2. Wave hand over the Hot button until the cursor is resting on “Filter life mode”
3. Wave hand over the dispense button to select “Filter life mode”
4. Wave hand over the dispense button until desired setting is selected
- Time sets filter alerts based on elapsed time
- Gallon sets filter alerts based on gallons consumed
- Both sets filter alerts based on time and gallons; the first to reach its limit will set off the filter alert in
program mode.
5. The cursor will first rest on enable/disable for the pre- sediment filter.
• To enable filter alarm alerts select enable, to turn off filter alarm alert select disable
• To change the filter alert wave hand over the dispense button while the cursor is over disable/
enable until the desired setting is selected.
• Wave hand over the hot button to move cursor to Life, time or both and set in order to change
the count down time until the filter alert is triggered.
• Usage will display total usage on the filter since the last time it was reset, this mode will reset
when the filter is reset.

PW90 APP
1. Enter the PW90 APP.
2. Press on the Filter Settings Tab.
3. Specify if you would like alerts to be set to time, gallons, or whichever comes first between time or gallons.
4. The time and gallons can be adjusted to desired amounts for each individual filter.
5. Alerts can also be turned on or off for all filters listed; those that do not apply to the system will be automatically turned
off.
PW90 CT
If changing the filter life sengs on the PW90CT is deemed necessary, it can be done Via Dip switch sengs on the
main board. Please see dip switch chart below.

4. Spray 1 part hydrogen peroxide to 4 parts water solution into the cold tank, let stand for 5 minutes and wipe clean with a rag.
5. Replace the lid and flush the tank.
6. Filters should be replaced using this schedule:
• Sediment= 1 year
• • Pre Carbon= 1 year
• RO Membrane= 2-3 years
• Boost= 1 year
• Post carbon= 2-3 years
• Lead and Cyst= 1 year

Filter Flushing
Please Note:
•Filters are located behind the bottom front panel on the PW90
•Filters are located behind an access panel located on the right side panel of the PW90CT
•The line wrapped in yellow tape line will represent the drain line
•The line wrapped in green tape will represents the source line
To Flush Pre-Filters
1. Remove the tubing from the filter side of the leak stop (gray
collet) and connect your source line directly to the tubing
with a union fitting.
2. Remove the tubing that connects to the “out” fitting on the
carbon block filter
head and connect a drain line to this fitting.
3. Turn the water on and flush according to the instructions on
the filter label
4. Turn off water when completely flushed
5. Remove the supply and drain lines and reconnect the tubing
to their originally installed location.
To Flush Post-Carbon Filter
1. Remove the “out” tubing from the RO membrane.
2. Connect the source line directly to the tubing that is
removed from this fitting.
3. Then connect a drain line to the “out” fitting on the boost
filter location
4. Note, if a boost filter will be used, please refrain from
installing the boost filter until after the “Post Carbon” filter is
flushed.
5. Turn the water on and flush according to the instructions on
the filter label. After turning the water off you may put the
tubing back to the previously installed locations.

Filter Flushing
Flushing RO Membrane (30 minutes)
1. It is important to flush the RO membrane with all filters inline for a full 30 minutes.
Although the RO membrane will flush down to 98% reduction in TDS within 5-10
minutes, the remaining 20 minutes is necessary to completely flush the preservative
out of the membrane and to flush the higher TDS water out of the post filter.
Note: Failure to complete this test, especially when using the “Boost” filter will
result in poor taste and may
cause damage to the equipment.
2. Connect the source line to the back of the system in the “tap water” bulkhead fitting.
3. Connect a drain line into the “RO drain” bulkhead fitting
Note: This is represented with the black tubing with no tape color
4. Plug the power cord into active power.
Note: Failure to do will result in the solenoid not engaging and as a result no
water will pass through the filters.
5. Keep the drain line connected to the “out” fitting from the “Boost” filter head.
6. Turn the water on for 30 minutes.
7. Prior to turning off the water supply, ensure:
Note: For RO only systems, the TDS is .02% vs the tap water TDS (98%
reduction).
Note: For Systems using Boost, the TDS is about 8-12 ppm higher than the RO
only variant.
8. If you have issues achieving these readings, make sure you have 60-70 PSI feeding
the system, the drain is not restricted in any way including a reversed check valve, the
inline flow restrictor is in place and working properly and the unit is properly flushed.
Please contact technical support for further assistance.
IF Installing or Flushing a Boost [+] Filter
1. Prior to returning the tubing after step B, move the supply
feed and connect to the tubing from the “out” of the “post
carbon” filter head.
2. Leave the drain line connected to the “out” fitting on the
top of the “Boost” filter head.
3. Install the “Boost” filter in position and turn the water and
flush according to the instructions on the filter label.
