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 W7 RO system requires a 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.
9. Perform final inspection of all installed water lines to ensure a leak free installation.
10. Instruct user on proper system operation.

INSTALLATION PROCEDURES
To install cold water:
Allow at least 30 minutes for adequate cooling, then select “Dispense”
To install hot water:
Select “Hot Select”. The dispense light will change from blue to red. Then select “Dispense”.
Note:
Hot water will require about 30 minutes to properly heat after the tank is full. Cold water will
require about 1 hour to chill.
Note:
Check UPC and Local Plumbing Codes to confirm that all connections are compliant.

FILTER FLUSHING PROCEDURES
Note
All filters and RO membranes must be flushed sufficiently prior to installation. The ball valve
located on the filter box will turn off the water to the filters and RO membrane. Turn to closed
position before removing filters. Remember to open the valve after replacing filters to turn the
water back on.
Flushing the purification system for the W7-RO
1. Install the supply water line to “Water In” bulkhead fitting and water drain line to “RO
Drain” bulk- head behind unit.
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 per
the label instructions (Approx. 5 minutes)
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:
I. For RO only systems, the TDS is .02% vs the tap water TDS (98% reduction).
II. For systems using the Mineral filter, the TDS will increase about 5-8 ppm higher
than the output directly from the RO.
a. 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
properly flushed. Please contact technical support for further assistance.
10. Filter flushing is now complete.
11. Replace lower front panel
Note
Check UPC & Local Plumbing Codes to confirm that all connections are compliant.

FILTER FLUSHING PROCEDURES
Flushing the filtration system for the W7-UF
1. Install the supply water line to “Water In” bulkhead.
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 filters and flush in an external flush station for
per the label instructions (Approx. 5 minutes)
5. Reinstall the filters in their original places.
6. Add a drain to the output of the last filter, turn the water on for 20-30 minutes. This will
flush the UF membrane helps 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, hot water, 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 to 10 minutes.
2. Select “Dispense” to ensure water dispenses from cold, select “Hot Select” and ensure
dispense light changes Red. Select “dispense” again while the dispense light is red and
ensure hot water dispenses.
3. Drain cold water into container using the dispense nozzle. Activate 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.

FINAL INSPECTION
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
- Wellsys W7 RO system should fill at a rate of about 5 .1 L/ min.
▪
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.
- Wellsys W7 UF system should fill in about 5 - 10 min
- If the system is not filling, then check the water supply and make sure you did not trip the
leak stop.
▪The leak stop can be reset by removing the cap below the unit and draining the water
out.
- Ensure the system’ s exterior is clean and all components are in place.
Other Items
- Once a system has been flushed it should remain plugged in and water should at a
minimum be dispensed occasionally.
- Avoid storing in your vehicle or warehouse with residual water in the tank, this will result in
a bad taste after installation.
- 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 i f
left overnight may result in a taste complaint that could even impact the cold tank.
- Never lay the system on its side.
