When mixers are delivered, check for shipping damage.   

Report damage to carrier and Jensen Mixers.  

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.
