The WOW RO System operates by removing contaminants from water at the molecular level. By
using your household water pressure to squeeze your water against a special membrane, water
molecules are separated from impuries. Rejected dissolved solids are automacally rinsed down
the drain leaving only high-quality, delicious water for you to use.
1. The WOW RO System will replenish approximately 1.5 gallons (5.7 L) in 35–90 minutes, de-
pending on your incoming water pressure, quality and temperature. This appliance is designed
with a self-regulang ush feature that limits the reject water to approximately 2 gallons (7.6 L)
for every gallon (liter) of treated water. Your appliance will perform beer and last longer with
heavy use. We encourage you to water house plants, provide water for pets, cook, mix drinks,
ll baeries, etc., with treated water. Cauon: The working capacity of this appliance depends
on the pressure and temperature of the water supply. This appliance is not guaranteed to
work properly with water pressure less than 20 psi (1.4 bar) and water temperature less than
40°F (4°C).

AVOID COMMON MISTAKES !
Review the most common missed steps made BEFORE starng. This will ensure an easy and
successful installaon.
1. Prepare and install all service components such as RO faucet, drain, and valve before
installing WOW RO System (Pages 26-28).
2. Fully pre-ll lter cartridges according to Step 3 (Page 11) to remove all air before
aaching to system.
3. When installing pre-lled lters to system, you MUST make sure they are properly
aached and engaged to the stop tabs per Step 3 (Figure 3, Page 11) instrucons.
Filters are labeled PRE, POST and RO. Ensure each lter matches posion on RO unit
manifold.
4. If replacing an exisng RO unit under the sink, you MUST ensure an independent iso-
laon valve is used between the WOW RO System and any added outlets. Without an
isolaon valve, the WOW RO System will not start. Refer to Secon 2 for connecng
addional appliances.
5. Before beginning Start-up Procedures (Step 5, Page 13) make sure all tube connecons
match the Figure 1 diagram on Page 4.
6. Make sure unit is ONLY connected to a cold water supply (Page 7).
7. If your connecons to and from WOW RO System have a leak (even one drop), the sys-
tem will not work. Repair leak (see Troubleshoong if necessary) and repeat Start-up
Procedures (Step 5, Page 13).
8. To avoid air-gap overowing onto counter, air-gap return line must never have loops or
sags in tubing.
9. If you are not using WOW’s RO installaon kit, it is crical that installers use correct
color coded tubing (See installaon kit contents, Page 8) to ensure easy trouble
shoong or add-on appliance follow-up.
10..If replacing an exisng RO unit, make sure you replace all old tubing with new color
coded tubing.

Start-up Procedure
Before the WOW RO System is operaonal, it must be properly primed by removing all air from
the unit.
Purging the system:
A. Make sure the RO faucet and all other outlets using an isolaon valve are CLOSED.
B. Turn feed water adapter Valve and emergency shut-o valve on. Noce the sound of water
lling the system.
C. Within 3-4 minutes, the waste line from the system will open with a noceable exhaust of air
and water.
D. Aer waing another minute, open RO faucet. Noce air/water exhausng from faucet port.
Wait for a steady stream of water and then CLOSE the faucet.
E. Within 2 minutes, the waste port will open again with a shot of air/water exhausng. At this
point, let the tank ll for approximately 45 minutes.
F. Aer system shuts down (indicated by no audible or visible drain ow), open RO faucet and
empty system to a trickle. At this point, the system should have generated a full gallon and a
half of water. If not, see Note 1 below or refer to Troubleshoong Guide (Page 35).
G. Turn o RO faucet and let water make-up process rell tank (approximately 45 minutes).
H. The unit is operaonal, but it is required to repeat this process (Steps F & G) ve mes to com-
pletely prep and ush lter cartridges and ensure TDS levels are at their minimums. This will
guarantee the best tasng water immediately.
I. System is now fully operaonal! If system does not work, refer to Troubleshoong Guide.
Note 1: If your connecons along any FA lines have a leak (even one drop), the system
will not work. Repair leak and repeat Start-up Procedure.
Note 2: See Pages 15-21 if adding any appliances.
Note 3: Unlike tradional capve air RO systems, the WOW RO System will always have
water in the tank. This fact does not change the need to follow Steps A-F for start-up.

Secon 2
Connecng Addional Appliances to
WOW RO System
There are many reasons why addional storage is required. If the unit is installed in houses with
larger families, cooking needs alone may warrant more storage. If family lls water boles ex-
ceeding 1½ gallons at same me, addional storage will be required. In addion, devices with
larger storage capacies like coolers will require greater draw down needs. Draw down refers to
amount of water that is released when opening up faucet and emptying tank from start to nish
(single pull). A standard WOW RO System holds 1½ gallons. The WOW RO System has been de-
signed in a modular format to add addional storage tanks as needed.

15
The WOW RO System is uniquely designed to connect to one or more appliances (Figure 5), includ-
ing refrigerator icemakers/door dispensers, coolers (both gravity fed and pressurized), under-the-
counter hot & cold vented systems, commercial steamers (restaurants), commercial coee makers
and other appliances that benet from RO water. This secon addresses “Do’s and Don’ts” of con-
necng to one or more appliances. It also addresses how to determine storage and expansion
needs depending on how many appliances are hooked up.
General MUST Do’s for connecng ANY addional appliances:
A. It’s a must that the lter and water lines to any and all added
outlets be clear of air. Note: System will not work with air in
the lines.
B. Close isolaon lines to all addional outlets.
C. Charge system to its full status (refer to Start-up, Page 13).
D. Follow the instrucons provided from Pages 16-22.
Determining Your Expansion and Storage Needs:
A standard WOW RO System holds 1½ gallons. The WOW RO System has been designed in a mod-
ular format to add addional storage tanks as needed.
Review chart below for each device connected. Add all addional tanks needed from right hand
column to determine complete storage needs.
* Check device manual for actual reservoir capacity.
