INSTALLATION
The units are shipped with the mo-
tor wires disconnected. Carefully
connect motor wires for desired op-
erating voltage as indicated on the
wiring diagram on page 13. Model
SPD-2073 will be wired for 230V.
The other models will not. Be cer-
tain to use electrical connectors of
adequate size. The table below pro-
vides wire size information.
The 1 HP motor is protected with
an internal automatic reset overload.
However, it is advisable to provide
additional protection with fuse or cir-
cuit breaker.
The motor should turn the
spreader blade counterclockwise as
viewed from above the unit. If the
three phase unit turns clockwise,
the rotation can be changed.
This may be done by interchanging
any two of the three power wire con-
nections. The rotation cannot be re-
versed on single phase unit.
Make sure eyebolt is securely
fastened to motor before installing
spreader. DO NOT STAND UNDER-
NEATH UNIT WHILE IT IS LIFTED
INTO PLACE.
