INSTALLATION OF WATER SUPPLY:
IMPORTANT: NU–VU® strongly recommends that SOFT WATER ONLY be used in any unit requiring
a water supply. Also, a good quality water filter MUST be installed in-line between the unit connection
and the water supply to guard against clogging and mineral build-up in the components. This is
extremely important in areas having hard water. The water filter may be installed at the water source or
adjacent to the Water Inlet Fitting on the rear or side of the unit, whichever is more convenient for you.
This equipment is to be installed to comply with the applicable federal, state and local plumbing codes
having jurisdiction.
Please follow these steps to connect a water supply to your unit:
A. Run ¼" tubing from the water supply line to the unit location. Allow some slack for final unit
positioning and service. Avoid any kinks or strains on the tubing and place the tubing where it
will not be damaged in any way.
B. The tubing end that attaches to the unit must not be damaged or deformed in any way. The cut
end should be cut straight and clean with no deforming of the tubing. All burrs and sharp
edges should be removed to ensure a proper fit and leak-free connection.
C. Position the tubing so that the tubing runs straight into the Water Intake Fitting. Be careful not
to kink the tubing if you bend it, and do not bend the tubing within two (2) inches of the end.
D. The two-part compression fitting (tapered collar and nut) is placed approximately 1" onto the
tubing so that the collar is inside of the nut and the threaded opening of the nut is toward the
Water Intake Fitting.
E. Push the tubing all the way into the Water Intake Fitting (approximately ¼") and hold it there
while you thread the compression nut onto the Water Intake Fitting. Tighten the compression
nut with an open-end wrench. DO NOT OVER–TIGHTEN!!! If the joint leaks when tested and
further gentle tightening does not stop the leak the two-part compression fitting must be
replaced.
Careful attention to these simple procedures will help to ensure an installation without leaks. If you have
any questions or problems please call the NU–VU® Service Department at (800) 338-9886.
