INSTALLATION PROCEDURES –
Read before installation
WARNING: Maximum water pressure (including any potential pressure spikes) of the water
supply line to the system must not exceed 70 PSI (5.5 bar). Failure to comply will void the
warranty. The manufacturer accepts no liability for damage caused by excessive water
pressure.
1. Always check local plumbing codes before tapping into water supply line and drain line. Tap into
the supply line with an approved connector.
2. Once the unit and filtration system flushing procedures are complete, determine the best
installation location. Consider user convenience, electrical access and water access. The unit
performs optimally if within 20 feet of a cold-water supply line. Connect only to a cold water
supply. Do not install Feed Water Assembly on the Hot Water Line. Do not place unit where
it will be exposed to rain, freezing temperatures or direct sunlight.
3. The rear of the unit should be installed at least 2” (5 cm) from any vertical surface to ensure
proper air circulation.
4. Use only ¼” OD copper or plastic tubing to connect your water supply and drain to the cooler
water inlet and drain port. The inlet and drain ports are quick connect fittings. Units are shipped
with plugs in each fitting. Remove the plugs prior to inserting water supply and drain lines. A water
shut off valve is recommended between the inlet connection to the cooler and the water supply
connection.
5. The W9CT RO system requires a waste or drain line for the RO membrane. The drain line should
include an Air Gap and back flow restrictor. See diagram.
6. Check the available power supply to assure proper electrical service. In the U.S., the voltage
specification is 115 volt 60 hertz. Voltage outside of this specification will affect the system
performance
7. Water filtration system will begin operating, verify proper water production.
8. Turn the Heating System switch on the back of the unit to the “ON” position when hot tank is full.
9. Perform final inspection of all installed water lines to ensure a leak free installation.
10. Instruct user on proper system operation.
To Dispense Cold Water:
Allow at least 30 minutes for adequate cooling, then wave hand in front of the Cold
Water sensor.
To Dispense Hot Water:
Allow at least 30 minutes for adequate heating, then wave hand over hot water select sensor, then the dispense sensor
NOTE: Check UPC and Local Plumbing Codes to confirm that all connections are in
compliance.

SOURCE WATER AND DRAIN INSTALLATION PROCEDURES
WARNING: Maximum water pressure (Including any possible pressure spikes) of the water supply
line to the unit must not exceed 80 PSI (5.5 bar). Failure to comply will void the warranty.
The manufacturer accepts no liability for damage caused by excessive water pressure.
1. Determine the best installation location considering customer preference,
electrical outlet, water line access, and if applicable, drain locations. The system
must have 2” clearance from the wall.
2. In most cases the water supply will be located under a sink that has a 3/8” cold
water line.
Install a compression (3/8”X3/8”X1/4” tube) fitting on the cold water line
above the shut off valve. See diagram below. Do not install Feed Water
Assembly on the Hot Water Line.
3. The W9CT-RO systems require a waste or drain line for the RO
membrane. The drain line should include an Air Gap and back flow
restrictor. See diagram.
NOTE: Check UPC and Local Plumbing Codes to confirm that all
connections are in compliance.

Filter Flushing Procedures for
Wellsys “Quick Change™” Filter Configuration
All filters and RO membranes must be flushed sufficiently prior to
installation. Summary and detailed instructions provided below.
Flushing the Purification for the W9 RO (Summary instructions)
(Full instructions with images can be found in the following section)
1. Connect the source water line to the “tap water” port on the back of the unit
2. Remove the right-side panel to access the filters
3. Cover the leak stop with a towel
4. Remove the top lid for easier access to the solenoid valve
5. Remove the tubing going into the input of the solenoid and connect this tubing
to a drain
a. Note: The solenoid and between the Pre carbon and the RO membrane
6. Turn water on for 5 minutes
a. This will flush the Pre sediment and the Pre carbon
b. After this step is complete turn the water off
7. Remove the Bio-Sure Plus filter and install in the Pre carbon position of the filter
bank
8. Turn the water on for 5 minutes
a. This will allow the Bio-sure Plus to properly flush
9. Reinstall the Bio-sure Plus in its proper position
10. Move the Sediment filter to the 2nd position where the Pre carbon filter is
normally installed
11. Move the TCR post filter to the 1st position where the Pre-Sediment is normally
installed
12. Reverse your product water and drain line to allow you to back flush the TCR
filter
13. Turn water on for 5 minutes
a. This will cause the water to flow through the Sediment filter and then
backwards through the TCR to help avoid flushing carbon into the
sediment portion of the TCR filter
14. Return all filters and lines to their original location
15. Install a drain to the RO port on the back of the unit
16. Install a secondary drain to the tubing that is connected to the input of the tank
so that the tank will not fill during the next step
17. Plug power to the system to allow the solenoid to activate
18. Turn the water on for a minimum of 30 minutes
a. This step will flush the RO and the higher TDS water out of the post filters
b. If your tap water is below 60 PSI this step may not work properly and may
10

negatively impact the performance of the system.
19. After this step is complete reconnect the tubing to the tank and allow the tank.
After following the tank sanitization procedures, allow a tank full of water to fill
and then drain.
Flushing the UF Carbon Filters for the W9 UF
1. Install the supply water line to the “tap water” port on the back of the system
2. Remove right side access panel to access filters
3. Remove the top lid
4. Remove the tubing for product water going into the tank and connect the tube to
a drain
5. Remove the UF, Bio-sure Plus and TCR filters and set aside
6. Install filter bypass plugs in each of the locations for the removed filters
7. Turn the water on for 5 minutes
a. This will flush the Pre sediment and Pre carbon filters
8. Install the Bio sure Plus filter in position 4
a. This is where you remove it from during step 5
9. Turn water on for 5 minutes
a. This will allow the Bio sure Plus filter to be flushed
10. Install the TCR post carbon filter
11. Remove all other filters and replace with filter bypass plugs
12. Switch the product and drain lines
13. Turn water on for 5 minutes
a. This will allow the TCR carbon to be reverse flushed
b. Failure to reverse flush the TCR carbon will cause carbon dust to flush into
the sediment portion of the filter which will cause carbon dust to enter into
the tank during normal operation
14. Reinstall all filter into their proper position
15. Switch back the product water and drain line
16. Turn water on for 15-20 minutes
a. This will allow the UF membrane to be flushed
b. Note: never flush tap water direction into a membrane
17. Connect the tank tubing back to the tank
18. After following the tank sanitization instructions, allow the tank to fill 1-2 times
and drain
19. Reinstall all panels

Wellsys Quick Change filter flushing: Detailed instructions
To access the filters please remove the right-side cabinet door by first removing the 2 fastening
screws. After removing the side panel, you will see the familiar filter manifold setup including the
full size Wellsys Quick Change standard filters.
1. Filter flushing procedures.
NOTE: In the following photos:
•The black line represents the source line
•The blue line will represent the drain line
To Flush pre and bio-Sure Plus 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 pre carbon filter head and
connect a drain line to this fitting. See where the blue water line connects in the picture
below.
3. Turn the water on and flush for 5 minutes.
3.1. Turn off water when completely flushed
4. Remove pre carbon filter and the Bio-Sure Plus Filter.
5. Put the Bio-Sure Plus filter into the pre carbon head and repeat step 3.
6. Remove the supply and drain lines and reconnect the tubing to their originally
installed location.
7. Reconnect the Bio- Sure Plus filter into it’s original location, but leave the pre-
carbon filter uncnnected.
1212

To Flush the TCR filter:
1. The TCR filter must be flushed backwards.
2. Switch water lines, so that the blue drain line is in the input side of the sediment head and the
black water supply line is in the out put side of the pre carbon filter head.
3. Remove the sediment filter and connect it to the pre carbon head.
4. Remove the TCR filter and connect it to the sediment filter head. Please see arrangement in the
picture below.
5. Turn the water on and flush for 3 minutes.
6. After turning the water off you may put the tubing and all filters back to the previously installed
locations.
Flushing the RO membrane for 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.
a. Failure to complete this test, especially when using the “Boost” filter will result in poor
taste and may cause further 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
a. This is represented with the blue tubing .
4. Plug the power cord into active power.
1313

a. Failure to do will result in the solenoid not engaging and as a result no water will pass
through the filters.
5. Connect a drain line to the output side of the TCR head. This will allow you to flush filters into a
bucket, or sink. Please see Blue water line placement in the picture below.
6. Turn the water on for 30 minutes.
7. Prior to turning off the water supply, ensure:
a. For RO only systems, the TDS is .02% vs the tap water TDS (98% reduction).
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.

FLUSHING THE COMPLETE SYSTEM
During the following steps you should be checking for any leaks, loose fittings, hot
water, cold water and production rate. See next Section- Final inspection.
Sanitize the cold tank
It is strongly encouraged that all systems are sanitized using a mixture of Hydrogen Peroxide and
water prior to placing in the field. Please follow the follow steps to properly perform this important
step.
1. Remove the cold tank lid.
2. Using a mixture of Hydrogen Peroxide to water, spray the inside of the tank, lid, floats, and all
parts visible parts with a heavy mist of spray.
3. Using a clean towel or paper towel, wipe the Hydrogen Peroxide away from the surfaces.
4. Spray a light mist of spray again on all parts and put the lid back onto the unit.
5. Allow one tank full of water to full up and drain a single time.
6. It is strongly encouraged to perform this step on each annual service call as well.
15

Inspection
•Turn the water to the system on, plug the system in and let the reservoir fill. RO
systems will fill in one to two hours. Filtration (M) system will fill in 5 to10 minutes.
•Activate dispense sensors to verify flow from hot and cold tanks.
•Drain cold water into container using the dispense nozzle. Activate touchless
dispense sensor until water flow ceases.
•Located on the rear of the system is a hot tank drain. Holding a bucket under the
drain, remove drain cap and allow the system to drain until water flow stops.
Replace drain cap.
•Repeat above steps.
•Allow system to fill.
•Turn hot switch located on back of unit to “ON” position.
•Allow unit to sit for up to 2 hours to reach optimal operating temperature.
•Verify the following:
•There are no leaks or loose components.
•The hot water is over 160°F.
•The cold water is below 50°F.
•Confirm acceptable product water flow
•W9CT RO systems- Average tank fill for RO systems is 45 minutes.
•W9CT UF systems- Average tank fill for filtration systems is 5 minutes.
•The system exterior is clean, and all components are in place.
OTHER ITEMS
1. Once a system has been flushed it should remain plugged in and water
dispensed occasionally.
2. Always drain the system before moving it. It is not necessary to drain the Hot Tank
completely through the rear Hot Tank drain. Leaving water in the Hot Tank will allow
turning on the Hot Tank immediately after installation of the system.
3. Be sure that if water is left in hot tank the system is installed the same day. Leaving
stagnant water in the tank may cause taste issues.
16

4. Never lay the system on its side.
W9CT System Programming:
This system uses dip switches for programming. The W9CT allows for fully adjustable filter alert
settings, ability to turn off filter alerts, and adjustable temperature settings.
The system comes preset with the following settings highlighted in yellow:
17

System Inspection
When changing filters or performing service, the following items should be completed.
1. Visual Inspection
2. Hose & fitting inspection
3. Electrical inspection
4. Pressure & flow test
5. Filter monitoring system reset
6. Gallon counter reset to zero. Refer to procedure below.
7. Clean the exterior of system and condenser coils on rear of system.
8. Temperature check (Cold water should be below 50°F, Hot water should be above 160°F)
9. TDS check
10. Hot tank switch On
11. Site clean up
18

1. Service indicator: The Service indicator may illuminate for 2 reasons. 1.) Water has triggered the leak
sensor. 2.) The filter life has reached its limit. NOTE: The filter indicator is optional and must be activated
by the dealer using the Dip Switches. We strongly suggest NOT activating the optional Filter Life warning
because different usage may create unwanted service calls. The filter life can be set by the dealer as
described int eh Dip Switch section. If the Service indicator is lit:
a. First check inside the lower front panel to ensure there are is no standing water on the leak
continuity sensor on the bottom plate.
i. If there is water, check for the source and dry the sensor and the Service light will turn off
b. Confirm Beep tone is turned on for the following step
c. The filters have reached their useful life as determined by your Dip Switch settings. To reset the
filter life aspect of the Service light:
i. Hold hand over HOT SELECT for 5 seconds until the Service indicator flashes
ii. Remove hand and then place hands over both the HOT SELECT and DISPENSE sensors for 5
seconds until a chime is heard
2. Flow Rate: The dispense Flow Rate on the Ascent 80 is set to 3 liters per minute (3 L/min). This is twice as
fast as a traditional cooler and is ideal for filling larger bottles. However, in certain settings the flow may be
too fast. An example is a waiting room that provides only small cups for the visitors. The Flow Rate can be
reduced to 2 liters per minute (2 L/min) using the following steps:
a. Confirm Beep tone is turned on
b. Hold both hands over HOT SELECT and DISPENSE sensors simultaneously for 5 seconds until the
audible Chime is heard
c. Remove hands and again place in front of HOT SELECT and DISPENSE sensors and hold for around 5
seconds until the audible Chime is heard
d. To reset the Flow Rate, repeat the above steps
In addition to the programming done with the Dip Switches, there are 3 items that can be changed using the
sensors as the programming tool: Service indicator, Flow Rate, and audible Beep tone.
NOTE: The Ascent 80 makes a Beep noise when a sensor is triggered. For programming, there is a second noise,
which we call a Chime. The Chime is an ascending tone of 3 to 6 notes. Do not assume the Beep is the Chime
1. Beep tone: The unit makes a Beep when a sensor is activated. This tone can be tuned off if the customer
desires silence. NOTE that when this tone is turned off, it will need to be turned on again for to hear the
Chimes referred to in the other following instructions. To turn off Beep tome:
a. Hold hand over HOT SELECT sensor for 1 second.
b. Then hold hand in front of DISPENSE sensor 5 times. The Beep should now be silenced
c. To restart the audible Beep, repeat above steps
19

Preventive
Maintenance:
1. Change filters according to the filter change schedule
2. Reset the filter alert using the instructions above
3. Drain the system and use Hydrogen Peroxide to sanitize the system
4. Check all fittings for signs of scale or wear and replace as needed
5. Check condition of the float mechanisms. Pay special attention to ensure no water has infiltrated the float
6. Check solenoids for proper function. Dripping solenoids should replaced
Every 5 years, in addition to the above, perform the following:
1. Replace all internal fittings and tubing
2. Replace all solenoid and fill valves.
