Home Duo System
1. Verify the water main has been
shut off.
2. Using a stud finder, attach mounting
bracket to the studs in the wall.
3. Remove the system from package.
Remove the filter and cartridge from
the housing. Be sure to check inside
the system for loose foam, plastic,
or package contents.
4. With the filter side of the head near
the inlet pipe, install the system by
attaching the head to the mounting
bracket. Ensure that the system is
installed vertically with the blue
head at the top of the system. Do
not invert the system.
5. Install a pressure regulator (E)
ahead of the NuvoH2O system. Set
for 45-65 PSI. A pressure spike,
though unlikely, can still damage
the system if it is not protected and
potentially result in leaks.
6. Install a bypass. See the diagram
on page 4.
7. Use flexible hoses to connect
the inlet pipe to the inlet port on
the system. Use flexible hoses to
connect the outlet port of the system
head to the outlet pipe. Failure to
use flexible hoses may result in
water leakage.
8. Use 3-4 wraps of Teflon tape to seal
the connections.
9. Lubricate (included) the O-rings at
the top of the housing sump.
10. Remove the protective plastic wrap
from the cartridge and filters before
inserting back into housing.
11. Insert and seat the cartridge and
filter into the sump.
Water softening cartridge: the small,
round holes on the side of the
cartridge must be at the top. See the
cartridge replacement instructions
for more details.
12. One at a time, carefully attach both
sumps (now with the cartridge and
filter inside) to head by rotating the
collar clockwise. Secure with the
wrench provided. Note: Be sure
to install the clear sump with the
carbon filter on the filter side of
the head.
13. Open the pressure release valve
on the top of the heads using a
screwdriver (do not remove
the pressure release valve, only
loosen it).
14. 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 heads,
tighten to close (B).
15. Close the first bypass valve (A),
allow cartridge to sit in the housing
without water flow for one hour.
Open main valve (C), thus allowing
water to flow throughout the
household while cartridge sits.
16. After one hour, close the top bypass
valve (C) and slowly open the first
and last bypass valves (A & D),
allowing water to flow through
the system.
