INSTALLATION
(continued)
INSTALL THE SOUNDHEAD DRIVE BELT as
illustrated. Slide the 54-67-0 idler pulley assembly against
the belt to set the belt tension. Securely tighten the (2) socket
head screws when belt tension is correct.
DO NOT OVERTIGHTEN either of the drive belts.
Timing belt tension should be sufficient to allow the belt cogs
to firmly engage the pulley teeth. Tighening beyond this point
shortens belt life and may damage shafts and bearings.
CONNECT THE AC INPUT to the motor termi-
nals. See the Data Plate on the motor to determine the correct
voltage requirements. The motor line must be externally
switched; no motor switch is provided with the Pro-35. Ap-
ply a second (unswitched) AC line to the Framing Lamp Power
Supply/ Changeover Power Supply.
