Water Supply Connections - Nu-Vu OP-2FM Owner's Manual

OP–2FM OWNER'S MANUAL
The following steps should be carefully followed to complete the electrical connections:
A. Take note of the labeling on the terminal connections (Line 1, Line 2, Line 3, and Neutral) at
the Power Terminal Block [1].
B. Carefully identify the power source connections and attach them to the appropriate terminals.
Make sure all connections are clean and tight.
IMPORTANT: IN ANY 240 VOLT THREE-PHASE SYSTEM THE WILD LEG (240
VOLTS-TO-NEUTRAL) MUST ALWAYS BE CONNECTED TO LINE 2!
C. The unit must be properly grounded BEFORE use by attaching a grounding wire to the Ground
Lug [2] next to the Power Terminal Block.
D. Carefully set all switches and controls on the unit to the OFF position, and engage the main
power supply.
E. Check the voltage at the terminals on the Power Terminal Block with a voltmeter and compare
the readings with the label listings on the side of the unit. If the readings match the unit is ready
for its INITIAL START–UP. If the readings DO NOT coincide you must call the NU-VU®
Service Department for instructions on changing the voltage and/or the phase.
NOTE: Diagrams and abbreviated instructions for phase-changing can be found on page
6. These diagrams are included to help you understand the procedure that we will explain
to you!!! DO NOT change the phase of your equipment without first calling the NU-VU
Service Department!!!
F. If your OP-2FM is not equipped with the AUTOMIST option, you can now replace the Side
Access Panel. Be careful not to pull or pinch any wires while installing the panel. If your
OP-2FM is equipped with the AUTOMIST option, leave the Side Access Panel off until the
water connection is completed.

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 (refer to Figure #1 on page
3). This is extremely important in areas having hard water. This filter may be installed at the water source
or adjacent to the water inlet on the back of the proofer, whichever is more convenient for you.
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 and leak-free connection.
C. Position the tubing so that the tubing runs straight into the intake Water Fitting [78]. This fitting is
found on the back of the proofer section, on the side opposite from the electrical connections. 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
intake Water Fitting.
E. Push the tubing all the way into the intake Fitting (approximately ¼") and hold it there while you
thread the compression nut onto the intake Fitting. Tighten the compression nut with an open-end
wrench, but do not over-tighten!
