SAFETY
Harmony Ball Return Manual –400-254-0223Rev. Date 3/16
4.0 SAFETY
It is important to lockout-tagout (LOTO) a ball return prior to installation or maintenance of the
lift. This safety procedure ensures that the ball return is powered off until the completion of
installation or maintenance. Hazardous power sources must be isolated and made inoperative.
This varies slightly depending on the country of installation:
4.1 U.S.A.
For installations in the U.S.A., each Harmony ball lift will need to be installed with a local AC
power disconnect (>10A, non-fused). The disconnect should be installed under the approach
below the ball rack access cover area. In order to LOTO lifts installed this way, the pullout
handle will need to be removed from the disconnect and then the disconnect must be locked
closed with the pullout handle removed. For other types, the disconnect switch must be placed
in the OFF position and then locked.
4.2 E.U.
For European installations, a Schuko power outlet should be installed within 3m (10ft) of the
ball lift. To LOTO this machine, a LOTO box must be placed around the ball lift’s electrical plug
and locked so that the plug cannot be placed in the socket. This ensures that no electricity can
reach the machine during installation or maintenance.
Disconnect’s pullout
handle must be removed
(or switch must be
moved to the OFF
position).
Disconnect’s hood/lid
must be locked.
The LOTO box must be closed and locked
around the plug.

5.0 TRANSPORTATION
The Harmony ball lift is shipped fastened to a wooden pallet. This prevents the lift from shifting
on the pallet during transport. It is encased in a cardboard box.
The Harmony lift weighs 180 lbs (82 kg) and should always be moved by two or more people. It
is recommended that once the ball lift is removed from the delivery truck, that it be placed on a
hand-truck and wheeled to its location on the approach. From there, two (or more) people
should be able to remove it from its pallet and lower it into the approach cutout.
5.1 Lift Points
It is recommended that the ball lift be lifted by the guide track brackets.

INSTALLATION

6.0 INSTALLATION
6.1 APPROACH OPENING
For replacing an existing installation, remove the old ball lift and fill in and/or cut out the
approach opening, as necessary, to meet the specifications shown below.
* Use caution when cutting through the approach surface as not to cut into the underlayment
support for the trap doors.

6.2 HARMONY BALL LIFT INSTALLATION
See Figure 2 as a typical installation of a Harmony ball return on a 16’ [4877mm] approach with
the rack flush with the end of the approach. Note the differences in the possible bezel
supports used. Bezel supports with an open slot at the top should be used with a ball lift
installation depth of 14.5”. If the bezel support does not have an open slot at the top, the lift
should be installed at a depth of 14.25”
Figure 2, Standard Layout & Rack Bezel Support
16’ (192”) Approach
Used with 14.5” install depth.
Used with 14.25” install depth.
See
below.

INSTALLATION
Harmony Ball Return Manual –400-254-0229Rev. Date 3/16
Figure 3, Ball Lift Mounting
Requirements
1. Position two (2) 2x6x18” boards on the subfloor as shown in Figure 2. Secure to the
subfloor using a powder-actuated nail gun for concrete, or nails for wood.
2. Place shims at four (4) lift-base mounting locations to achieve an install depth of 14.5”
[368mm]. Secure using nails.
3. This step will require two (2) people. Lower the lift through the opening in the approach.
Slide and tilt the lift away from the ball track. Lift up the end of the ball track and then slide
the lift into position.
4. Verify that the lift is plumb side-to-side and front-to-back, at 14.5” depth, and aligned to the
ball track. Secure to the floor using the supplied hardware. Then verify plumb, depth, and
alignment once more.
5. Lift the end of the ball track and place the adapter plate on the base plate over the four (4)
studs. Attach the ball track to the adapter plate using the supplied hardware as shown in
Figure 4.
6. Trim the rail cover to the rack side of the
ball lift.
7. Center the ball track to the ball lift and
then secure with the supplied hardware.
Test the alignment and height by rolling
a ball on the track and into the lift. Shim
the track adapter plate and adjust the
position to attain a smooth transition of
the ball into the lift. Use the specific
shims provided as shown in Figure 4.

INSTALLATION
Harmony Ball Return Manual –400-254-02210 Rev. Date 3/16
Figure 4, Track to Lift Connection
The dimensions specified herein are for a typical installation and assume an approach length of
16 ft. (192”). This typical installation will result in the ball rack ending flush with the end of the
approach. If the approach is longer or shorter than 16 ft., the end of the ball rack may or may
not line up with the end of the approach.
If the approach is less than 16 feet in length, or if more space is needed between the end of the
ball rack and other installed equipment, then you will have to offset the installation closer to
the foul line by the desired amount. If the location of the ball lift is shifted, it may be
necessary to cut and splice the underlane ball return track to accomplish the installation. The
ball track should be cut to the appropriate length before installing the lift.
