NuvoH2O Cartridge Replacement
1. Before replacing your cartridge, we
recommend having a towel on hand
and placing a bucket underneath
your softener system to catch any
water that may spill. The bucket
should also be used to carry your
spent cartridge as the concentrated
solution can damage flooring
if it drips.
2. Discontinue water flow to the
system by closing valves A and D
(see diagram on page 3). Open
valve C, allowing water to flow to
the home. Loosen pressure release
valve in the head of the system
with a screwdriver. Use towel to
absorb water that leaks from valve.
3. Using the black plastic wrench
provided, turn the blue collar
clockwise (left) to loosen the sump
from the head of the system.
CAUTION: The sump will be heavy
and full of water!
4. Remove the spent cartridge. Turn it
upside down into a sink or tub and
let it drain completely. The outside
of the cartridge can be rinsed
with warm water. The water that
empties from the cartridge will be
very concentrated. DO NOT allow
it to come in contact with copper,
stone (natural or unsealed), carpet,
cement, or other flooring.
5 Clean the inside of the sump with
dish soap, 1/2 teaspoon bleach,
and water. Rinse thoroughly.
6 Remove the plastic shrink wrap
from your new cartridge and insert
the cartridge into the sump. The
small, round holes on the side of the
cartridge must be at the top.
7. Be sure to align the cartridge
properly in the sump. Failure to
do so may cause the cartridge to
crack when tightening the collar
back to the head.
8. Inspect O-ring, on the top of the
sump, for wear. Ensure it is seated
properly. Lubricate O-ring with a
water-based lubricant or replace
as needed.
9. Place the sump directly under the
head. Carefully attach sump with
cartridge inside to head by rotating
clockwise (right). Secure with
wrench provided.
10. Open the first bypass valve (A),
allowing the sump to fill with water.
When water leaks from the pressure
release valve at the top of the head,
tighten to close (B).
11. Close the first bypass valve
(A), allow cartridge to sit in the
housing with minimal water flow
for one hour. Open main valve
(C), thus allowing water to flow
throughout the household while
the cartridge sits idle.
12. After one hour, close
the top bypass valve
(C) and open the firs
and last bypass valves
(A&D), allowing the
water to flow through
the system.
