INCOMING WATER
Incoming water pressure must be between 45 PSI and 80 PSI for NU Aqua no pump reverse osmosis systems.
For incoming water pressure below 45 PSI and as low as 15 PSI, we recommend our reverse osmosis systems
with booster pumps. If your water pressure is above 80 PSI you will need a pressure regulator for your system.
Test your water pressure occasionally to make sure the system is performing. If your water is microbiologically
unsafe or of unknown quality do not use this system without adequate disinfection before or after the system.
Extremely hot or cold incoming water will damage the system and cannot be used. Do not install where water
hammer conditions exist, you should install a water hammer arrestor
LEAKS
The included Leak Stop Valve must be installed. Inspect all connections after the installation to make sure no
leaks occur, wait until after the system is pressurized (turned on) to inspect again. Check the system occasional-
ly after installation or maintenance to make sure no leaks have developed. Install the system in a location with
adequate drainage.
GENERAL
This RO System unit is for climate controlled indoor use only. Exposure to overly high or low temperature ranges
will damage the unit. Follow all of your state and local laws and codes regarding plumbing even if they differ
from what is stated in this manual. If your state law requires it or you prefer to we recommend using a professio-
nal licensed installer or plumber who meets the requirements of this system. All O-Rings, fittings, tubing, filter
canisters, and teflon tape wear out after a certain period of time. The lifetime of your components are subject
to change with the quality of the water supplied. Do not handle an unwrapped filter directly with your bare
hands as this can cause early filter failure. Use appropriate eye and face protection when performing any
drilling.
MAINTENANCE
The owner/user is obligated to properly maintain the RO System when necessary, at least every 1 year. This
includes the following:
-Always use NU Aqua Systems replacement filters in accordance with the filter change schedule.
-Sanitize your system as often as needed (how often changes with the quality of incoming water).
At least every 3 years:
-Replace the tubing, fittings, and filter cartridges.
-Replace the Teflon Tape on all threaded connections and fittings.
-Replace the O-rings on the filter housings, membrane housing, fittings and filter cartridges.
-Replace any connectors and filter housings with proper replacement parts.
At least every 5 years:
-Replace the faucet

Sanitizing Your System Troubleshooting
Problem
Milky colored water
Air bubbles in water
Loud or noisy system
Slow production or no water
from RO faucet
Water taste or an
offensive smell
No drain water
Leaks
No water
TANK NOT FILLING
UV LIGHT
NOT TURNING ON
Solution
• Air in the system is normal with initial
installation and startup. This will clear up
within 1 to 2 weeks.
• Will disappear after system shutdown.
• Relocate drain saddle above P-trap.
• Blockage sometimes caused by debris
from garbage disposal or dishwasher.
•Normally it takes 1-2.5 hours to fill the
tank. Low water pressure and/or
temperature
can reduce production rate.
• Add pressure to the storage tank. The
pressure should be 8-10 PSI when the
tank is empty.
• Add a booster pump.
• Make sure tubing is straight.
• Replace prefilters.
• Replace RO membrane.
• Check for clog in drain line and clear.
•Replace inline carbon filter.
•Replace RO membrane.
• Replace the flow restrictor.
• Tighten fittings as necessary.
• Replace the O-ring.
. Realign drain saddle.
. Replace teflon tape with 7-10 wraps.
• Replace leak stop valve.
• Check water flows from feed water
adapter. If no water comes through,
replace the feed water adapter
• Connect the tank directly to feed
water adapter and fill for 1 minute. This
will help prime the tank
• Test on a new outlet that is known
to be working.
• Replace UV bulb
• Contact support

tion Instruction & Owner's Manual (“Manual”).
REPAIR OR REPLACEMENT
Repair or replacement during this three (3) year warranty does not include labor charges, freight charges or any other local

During the entire three (3) year warranty, NU Aqua Systems's obligation to repair or replace shall further be limited to repair or
replacement with the styles, models, products, colors, etc. of the Product that are available at the time of the repair or replace-
ment, and shall be limited to the repair or replacement of only the specific Product that fails due to a manufacturing defect.

tort, contract or otherwise, for any special, indirect, incidental, consequential, reliance, statutory, special, punitive or exemplary
damages, including, but not limited to, lost profits, loss of use, loss of time, inconvenience, damage to goodwill or reputation, or

warranty claims in excess of the Product expected lifetime.
