Introduction

This installation manual will guide you through the process of fitting a PianoDisc

reproducing piano system to virtually any grand piano. Along with the knowledge

and experience gained from a PianoDisc installation Seminar, this guide should

be an invaluable resource.

This document is considered confidential by PianoDisc, and is for the sole use of

PianoDisc Certified Technicians. It may not be reproduced, distributed or quoted

in whole or in part without the express written permission of PianoDisc.

This guide is only to be used in the installation of the following PianoDisc

Reproducing Systems: 228CFX, PianoCD and iQ.

PianoDisc systems may ONLY be installed by technicians who have been certified

by PianoDisc to perform such installations. If you have come into possession of

this manual and/or a Retrofit Kit and you are NOT a PianoDisc Certified

Technician, DO NOT ATTEMPT TO PERFORM THE INSTALLATION. Installations

not performed by a certified PianoDisc technician WILL NOT meet the

requirements for warranty protection, and such an installation will likely void the

piano manufacturer’s warranty for the instrument and the player system, and may

also be a violation of FCC rules.

Technicians may only be certified by attending the PianoDisc installation Seminar

at PianoDisc’s Factory and World Headquarters in Sacramento, CA, or by on site

training evaluation and certification by one of the PianoDisc Factory Installation

Technicians duly authorized to certify technicians. A candidate for PianoDisc

certification should be a Registered Piano Technician and a member of the Piano

Technicians Guild. A candidate who does not qualify under this rule will be

evaluated on an individual basis, with an emphasis on total experience as a piano

technician and possible previous experience in retrofitting pianos with other player

piano mechanisms.

equipment is installed and used in strict accordance with manual instructions. This

equipment has been tested and found to comply with the limits for a Class B

digital device, pursuant to part 15 of the FCC rules, which provide reasonable

protection against such interference.

If the equipment does cause harmful interference to radio or television reception,

which can be determined by turning the equipment on and off, the user is

encouraged to try to correct the interference by one or more of the following

measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a separate circuit from that of the

receiver.

• Consult PianoDisc, or an experienced radio/TV technician for help.

The user may find the following booklet prepared by the Federal Communications

Commission helpful:

8 PianoDisc Installation Guide

228CFX - PianoCD - iQ

Step 1: Disassemble the Piano

A. Remove the music desk and the fallboard. On many pianos, the

fallboard can be easily removed by lifting it upward and outward. On others,

it is attached to cheek blocks at the ends of the keyboard. These blocks

must be removed first, usually by loosening the long screws beneath the

keybed.

B. Measure the key height. An important measurement must be taken here –

that of the key height for the particular piano on which you are working.

Carefully measure the distance from the top of the keybed to the top of the

(white) key covering. Record this measurement for later use. (Note: the

height of a black key is measured from the top of an adjacent white key.

This height is about ½” (13 mm). These measurements are also available

from piano manufactures and the Piano Technicians Guild.

Mark the location of the Keyframe on the keybed.

C. Remove the action. Be especially careful that your fingers do not push the

keys down while pulling out the action. The slightest pressure on a key will

lift its hammer, thereby causing the hammer to catch on the pinblock and

may cause damage when the action is pulled out of the piano. Place the

action on a table. If the piano arrives at your workshop already on its side,

you will need to tilt it in order to remove the action. New pianos shipped in a

crate, usually have the hammers tied down. If this is the case, the action

can be pulled out with the piano on its side.

D. Removal of the lid is optional. If left in place, secure it with a rubber inner

tube. If it is removed, put it in a safe location. To guard against losing the

hinge pins, tape each pin to its hinge.

E. Place the piano on its bass side on a carpeted piano board. With a soft

lead pencil, draw the outline of the right and left legs on the bottom of the

keybed. Remove the legs. With a permanent marker, number each leg and

the keybed point from which it came. These marks will be indispensable

later when some portions of the legs may need to be cut away.

F. Remove the pedal lyre and all trapwork. Remove the lyre and secure it in

a safe place. Remove all trapwork saving only the shift lever.

. . . . .

G. Remove the hammer stack. The hammers are mounted on a small metal

frame attached by four brackets to the wooden keyframe. Remove the

screws – 2 per bracket, for a total of 8 or 10. The screws may vary in size;

consequently, mark each one in such a manner as to insure its return to the

original position in the keyframe. Lift the action “stack” from the keyframe

and place it some where safe.

Pianos with leg bolts sometimes present a problem when attempting access to

all 88 keys. It may be necessary to omit some key solenoids on both ends of

the keyboard due to the interference of the leg bolt plate in the keybed.

To determine this key access –

A. Remove the action from the piano

B. Measure from the keyframe rest block (on the bass side) to the first leg bolt

plate. Transfer the measurement to the keyframe. (see figure 1A and 1B -

Measurement X)

C. Now measure from the keyframe rest block to the leg bolt plate in high

treble. Transfer this measurement to the keyframe. See figure 1A and 1B –

Measurement Y.

Figure 1B

Step 2: Measure the key groups

A. Establish the key groups. The front of the keys are evenly spaced in one

continuous line: left to right, numbered 1 through 88. The stack is typically

divided into four groups. The group at the left, the bass, has the largest

hammers. This is Group 1. The mid-range group in the center of the

keyboard is Group 2. Moving to the right is the low treble area, Group 3.

Group 4 is the high treble area at the right end of the keyboard with the

smallest hammers. The small open spaces between these groups are

called “breaks”. (Figure 2A)

B. Place and mark the rail blanks. Position solenoid rail blank on damper lift

felt centering rail bracket locations for best support (Figure 2C)

C. Mark the starting and ending point on the rail (first and last keys of that

section) (Figure 2B)

D. Always start with short stem solenoid for the first key and only mark the

long stem solenoid locations.
