STEP 3. HUMIDIFIER INSTALLATION
Install the Humidifiers
(Figure 8)
on the back side of the piano.
Make sure the elbow openings are facing each other as in
Figure 1
. The Humidifier with the watering tube should be
placed at the bass end of the piano. Some pianos will have 4
bays (4 openings contained by 5 beams or posts). Some will
have 5 bays (5 openings contained by 6 beams). In the case of
the 4-bay piano, use the 2 inner bays. In the case of the 5-bay
piano, use bays 2 and 4 counting from either side.
Mount the large diameter tube on the elbow of each Humidifier.
The elbows are sealed at the factory to make sure they do not
leak, and tightening or loosening them may destroy this seal.
Once you are assured that you have the best, level route
between the Humidifiers for the tube, mark the tube for cutting,
making absolutely sure there is enough tubing to go over both
elbows. Note: the use of C-Clips
(shown in Figure 8 and 10)
to
support the tube will require 1 or 2 inches additional length of
tube, so allow for this before cutting. Before cutting off excess
tubing, move the locking rings toward the center of the tube
(Figure 9)
.
Move the locking rings to the ends of the cut tubing. Position
them 2 inches from each end. Slip the tube end over the elbow
on each Humidifier. It’s important that you support the elbow
when pushing on it to avoid breaking the seal between the
elbow and the Humidifer. It may be easier to support the
elbows with the Humidifiers outside the piano. A little water on
the inside of the tube ends will provide some lubricant to
enable the tube to slip over the elbow.
Slip the locking rings onto the tube ends. The prongs for the
locking rings should face outward
(Figure 10).
With the tube
mounted on the Humidifiers, measure where the tube will lie
across the beams and then mount the supporting C-Clips
accordingly on the beams, using 1/2-inch screws
(Figure 10).
Now you are ready to secure the Humidifier in the bays with the
Velcro which is attached to the sides and bottoms of the tanks.
Be aware that the Humidifiers may overhang the back of the
piano. This is okay—the Velcro will hold them in place. Note
the attachment of the Velcro on the beams in
Figure 8.
Use
alcohol pads to clean the outside of the beams 4 to 5 inches up
