3.3 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 XDQ 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 XDQ 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.
SECTION 4 – INSTALLING THE MIXER SHAFT
4.1 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.

4.2 To install the mixer shaft, back off the chuck screw (refer to Figure 3) as far as the limit pin will allow. DO NOT
FORCE. 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. 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.
