5. Installation

5.1 Installation

The mixer can be placed direct on the floor. Foundation bolts in the floor are only neces-sary under special conditions, e.g. in ships. If the 20 L mixer is placed on a bench stand,it must be fastened with the enclosed bolts.

If the floor is not level, the position of the mixer can be corrected by loosening the screwsplaced at the bottom of the outer left side of the mixer, whereafter the legs can be turned.When the mixer is placed corrrecly, the screws are tightened again.

Ensure that the voltage, phase and hertz printed on the identification plate of the mixerare correct compared with that of the place of installation.

The identification plate is located at the top of the right side of the mixer.

Be sure the mixer is properly connected to the incoming power supply and that the groundor earth connection is made.

If the mixer is provided with a five core cable, the mixer must also be connected to 0.

The arrow on the front of the planetary head is showing the direction of rotation of theplanetary head.

On 3-phase motors the direction of rotation can be changed by interchanging 2 phases ofthe connecting cable or of the motor.

working position, and repeat the procedure if the measure is not correct• ensure that all mixing tools are fitting in the bowl

6.1.1 Lubrication and Maintenance

When the mixer is used regularly, the varispeed system must be lubricated approx. onceper month.

When the mixer is used intensively or often used without changes in speed ,the lubricationintervals should be shortened.

Start the mixer and increase the speed up to approx. 50%. Stop the mixer and take off thetop cover of the mixer by removing the 2 screws.

On top of the shafts of the pulley sets there is a grease nipple, one on each pulley set.Press the grease through the grease nipples until the grease gun feels hard, or until greaseis pressed out between the shaft and the pulleys.

Grease for the shafts of the pulley sets: ESSO NEBULA EP1 or EP2, or another ball bear-ing grease NLGI 1or NLGI 2.

Put the top cover back and remember to put in the 2 screws securing the cover.

The mixer must not be started until these screws are mounted.

Start the mixer and set the speed back to low speed.

Stop the mixer and fill up the grease gun with new grease to be ready for the next lubri-cation.

15


When repairing the planetary head which is greased for life, the grease Q8 GIOTTONLGL 1 should be used in gear wheel, gear wheel rim and gear for attachment drive, ifany.

The needle bearings of the planetary head must not be greased with this type of grease

Only grease Q8 GIOOTO NLGI 1 can be used, and it must not be mixed with other typesof grease.
