INSTALLATION PROCEDURES
WARNING: Maximum water pressure (including any potential pressure spikes) of
the water supply line to the system 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. 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 W9 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 110/120 volt 60 hertz. Voltage outside
of this specification will affect the system performance
7. Water filtration system must be flushed in accordance with the
instructions. Once operating, verify proper water production.
8. Be sure to dispense water from the hot tank prior to turning on the hot
tank switch on the rear of the unit. When ready, turn the Heating System
switch on the back of the unit to the “ON” position.

FILTER FLUSHING PROCEDURES
Filter Flushing Procedures for W9 Filter Configuration
All filters and RO membranes must be flushed sufficiently prior to installation.
NOTE:
The ball valve located on the filter box will turn off the water to the filters and RO membrane. Turn
to closedposition before removing filters. Remember to open the valve after replacing filters to
turn the water back on.
Flushing the Purification for the Wellsys W9 RO:
1. Install the supply water line to “Water In” bulkhead and water drain line to “RO Drain” bulkhead in
back ofunit.
2. Do not plug the system into the AC socket. (No Power)
3. Remove lower front panel to access filters. Remove single screw behind drip tray, push down on
the front panel and then gently pull the panel off.
4. Remove the sediment, carbon and post carbon filters and flush on a pre- flush station for 5
minutes each.
5. Reinstall the sediment and carbon filters in their original places.
6. Connect the drain line to the bottom of the RO and then install the RO membrane in the vacant
filter head.
7. Add a drain line to the output of the last filter head.
8. Turn on the water to the filters, plug the system in and let the water run for 30 minutes or greater.
9. Check the TDS
a. Prior to turning off the water supply, ensure:
b. For RO only systems, the TDS is .02% vs the tap water TDS (98% reduction).
c. For Systems using the Mineral filter, the TDS will increase about 20 ppm higher than
theoutput directly from the RO.
i. If you have issues achieving these reading, 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 properlyflushed. Please contact technical support
for further assistance.
10. Filter flushing is now complete.
11. Replace lower front panel
NOTE Example of RO Drain Installation:
Check UPC & Local Plumbing Codes to
confirm that all connections are in
compliance.

a. This will flush the UF membrane and also help regulate the TDS and alkalinity in the post filters.
7. Replace lower front panel.
FLUSHING THE ENTIRE SYSTEM
During the following steps you should be checking for any leaks, loose fittings, hotwater, cold
water and production rate.
See next Section- Final inspection.
1. 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 and UF systems will fill in 5 to10 minutes.
2. Wave hand over “Dispense” to ensure water dispenses from cold, wave hand over “Hot Select”
and ensure dispense light changes Red. Wave hand over dispense again while the dispense
light is red and ensure hot water dispenses.
3. Drain cold water into container using the dispense nozzle. Activate touchless dispense sensor
until water flow ceases. Water will stop dispensing after 45 seconds. Active again until cold tank
is drained.
4. Located behind the front panel is a hot tank drain that will drain the hot and about half of the
cold tank. Holding a bucket under the drain, remove drain cap and allow the system to drain until
water flow stops. Replace drain cap.
5. Repeat steps 1 through 4.
6. Allow system to fill.
7. Turn hot switch located on back of unit to “ON” position.
8. Allow unit to sit for 2-3 hours to fill and reach optimal operating temperature.

11
FINAL INSPECTION
Verify the following:
1. There are no leaks or loose components.
2. The hot water is over 160°F.
3. The cold water is below 50°F.
4. Confirm acceptable product water flow
5. Wellsys W9 RO system should fill at a rate of about 5.1 L/min.
a.
Note:
Incoming water pressure and drain correctly functioning will
have a significant impact on water flow. The flow will also
improve as the membrane breaks in.
6. Wellsys W9 UF system should fill in about 5-10 min
7. If the system is not filling, then check the water supply and also make
sure you did not trip the leak stop.
a. The leak stop can be reset by removing the cap below the unit
and draining the water out.
8. Ensure the system’s 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
should at a minimum be dispensed occasionally.
a. Avoid storing in your vehicle or warehouse with residual water in
the tank, this will result in a bad taste after installation.
2. Always drain the system before moving it. It is not necessary to drain
the Hot Tank completely through the rear Hot Tank drain if installing
same day. Leaving water in the Hot Tan will allow turning on the Hot
Tank immediately after installation of the system but if left overnight
may result in a taste complaint that could even impact the cold tank.
3. Never lay the system on its side.
