Installation, Operation, Maintenance
Installation Series 400 Fixed and Vari-Angle Mixers
Remove blank cover plate from tank nozzle and check Jensen supplied mixer cover plate for
correct size, hole location and orientation.
Clean gasket surface on tank nozzle and mating flange on mixer coverplate.
Mount propeller on shaft (secure both setscrews on propeller lock assembly) providing manway
is large enough for propeller to roll through opening. (See page 4 for propeller roll through
opening specs.)
Install gasket and bolt Mixer with coverplate to manway. No additional supports are necessary.
For units with factory mounted motors, the installation is now complete.
For units with the motor shipped separately or customers supplying their own motor; mount
the motor to the mounting plate and loosely position the drive pulley on the motor shaft. Install
belts and check alignment and belt tension as described on page 5.
Re-install all belt guards.
Startup
Recommended Operation, Periodic Maintenance
Make up the electrical wiring in such a manner that there is enough flexible cable from the
rigid conduit to the mixer to allow the VA mixer, if VA mixer is being installed, full swing.
Electrical hookup must be in accordance with existing electrical code for the area.
Remove belt guards and check belt deflection and alignment before startup. See (Page 4.)
Turn motor on for 5 seconds maximum, to check shaft or propeller rotation. The mixer shaft
must turn clockwise when viewing mixer from behind, looking towards the tank.
Once tank fluid is above mixer shaft, open AIR RELEASE valve (Pg. 11) to vent the trapped air
and allow tank product to lubricate the seal.
Start mixer after tank contents is 10 feet (3 meters) above the propeller. The only noise one
should hear is that of the propeller moving the fluid in the tank and the hum of the motor. If
any other noise is heard, shut down motor, investigate and correct.
Be sure the latch bar bolts are tight, if VA mixer was installed. If any excessive vibration is
detected, make sure the propeller tips are not less than 8” (203 mm) from any obstruction.
Check the motor current with an ampmeter. Check both electrical legs to be sure that the
amperage is less than that printed on the motor name tag.
Recheck belt deflection and tension after the first 8 hours of operation.
Units with factory installed actuator, see actuator operation sheet.
Units should be checked at least once within 24 hours of startup.
