2.5 Single Phase Motors for XDC30 thru 87 (or motors nameplated 1/4 thru 1 horsepower):
a . Totally enclosed motors are furnished with eight foot cords fitted with UL approved three prong
grounded plugs suitable for the correct voltage.
b . Explosion proof motors are furnished with a pipe tap connection and suitable leads. A conduit box with
internal switch is available for explosion proof service.
c . All DURA–MIX single phase motors are equipped with an internal over–temperature device with
manual reset. If the thermal trips, wait fifteen (15) minutes and depress the reset button on the motor
body. A click indicates reset.
2.6 Three Phase Motors:
a . All totally enclosed motors are equipped with a conduit box and suitable leads.
b . All explosion proof motors are furnished with a pipe tap connection and suitable leads.
IMPORTANT: ALL THREE PHASE MOTORS (except explosion proof on XDC 30 thru 65 or other XP
motors nameplated 3/4 horsepower and below) are equipped with over–temperature thermostats
which are designed to interrupt current in the holding coil of magnetic starters only. The motor
thermostats will reset themselves, but the control panel ”start” button must be depressed to start the
motor.
EXPLOSION PROOF MOTORS on XDC 30 thru 65 or XP motors nameplated 3/4 horsepower and
below are equipped with automatic over–temperature circuits which can trip and reset themselves
after the motor cools. TO AVOID INJURY DUE TO UNEXPECTED START UP, DISCONNECT FROM
POWER UNTIL THE MOTOR COOLS.
2.7 Procedure for units equipped with chuck:
a . To install the mixer shaft, back off the chuck screw (refer to Figure 1) as far as the limit pin will allow.
DO NOT FORCE.
b . Insert the mixer shaft into the chuck bore as far as it will go, and draw up the chuck screw with the
wrench provided, rotating the shaft slightly back and forth to make sure the chuck grip seats against
the flat of the shaft.
c . Tighten the chuck screw with the wrench provided. The wrench has been properly sized to tighten the
screw. DO NOT IMPACT THE WRENCH OR USE AN EXTENSION.
NOTE: A safety feature is provided by a slight taper in the flat on the mixer shaft. The shaft cannot drop
out unless the grip is intentionally released.

2.8 Procedure for units equipped with couplings:
a . Connect the mixer shaft (42) to the drive shaft (38) by bolting the coupling halves together.
CAUTION: Care should be exercised in order to prevent damage to the coupling rabbets, and to insure
proper seating of the coupling halves.
2.9 Position the impeller(s) on the mixer shaft. Refer to the specification sheet for recommended dual impeller
spacing. The larger wedge shaped portion of the hub body must face up towards the mixer. The bottom of
the hub is stamped ”DOWN”. Refer to Figure 2 for general orientation reference. Tighten impeller set screws
securely. For unusually severe conditions, the shaft should be spotted for the set screws.
