under the proofer compartment.

®
QB-3/9 is equipped with a bottom drain centered
directly under the Proofer Door. Please install the included Drain Pan [77] in the brackets under
the Proofer
if you have not already installed drain plumbing
. This drain prevents the build-up of
excessive water that may damage the Proofer Motor, Heating or Humidity Element, or a Sensor.
Connection of Optional Water Supply - -
This equipment must be installed in accordance with all applicable federal, state, province, and/or local
plumbing codes having jurisdiction.
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, adjacent to the water inlet on the
unit, or anywhere in between, whichever is more convenient for you.
A.
Run 1/4” OD tubing from the water supply line to the unit location. Allow some slack in the
tubing for final unit positioning and any future service requirements. Avoid any kinks or strains
on the tubing, and position the tubing where it will not be damaged in any way.
B.
The tubing end that attaches to the back of 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 or rough edges should be removed to ensure a proper and leak-free connection.
C.
Position the tubing so that it runs straight into the intake Water Fitting [76] on the rear of the
unit. Be careful not to kink the tubing if you bend it, and do not bend the tubing within two (2)
inches of the cut end.
