INSTALLATION - CLEANING - MAINTENANCE
INSTALLATION:
The mixer can be placed directly on the floor. Foundation bolts in the floor are necessary only under special conditions,
e.g. in ships.
If the 20-quart mixer is placed on a bench stand, it must be fastened with the bolts that fasten the unit to the
shipping pallet.
Ensure that the voltage, phase and hertz printed on the identification plate of the mixer are the same as that at 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 the ground or earth connection is made. The arrow on the front of the
planetary head (see drawing 2, page 1), indicates the direction of rotation of the planetary head. On three-phase motors
the direction of rotation can be changed by interchanging two phases of
the connecting cable or the motor. Electrical connections must be made in Lubrication Points
accordance with local regulations.
DOUGH HOOK CLEANING:
Special care should be given to cleaning the dough hook. The
Varimixer dough hook is manufactured of stainless steel and we rec-
ommend that it be cleaned and sanitized in a commercial dish
machine. An alternate cleaning procedure is to vigorously scrub the
dough hook with a hot water and detergent solution. Use a heavy
bristled brush. After cleaning, sanitize the dough hook by rinsing with
a 50 ppm solution of sodium hypochlorite.
CLEANING:
The mixer should be cleaned daily or after use. Wash with a soft
brush and pure water. Synthetic detergents should be used with care
as they destroy the lubricants of the mixer. Washing with a hose is
not recommended. Bowls and mixing tools should be washed in
detergents which do not attack aluminum. Detergent suppliers will be
able to recommend the right type.
LUBRICATION AND MAINTENANCE:
When the mixer is used regularly, the varispeed system must be
lubricated approximately once each month. When the mixer is exten-
sively used, or used often without changes in speed, lubrication inter-
vals should be shorter.
DIRECTIONS FOR LUBRICATION:
Start the mixer and increase the speed to approximately 50%. Stop
the mixer and remove the top cover by removing the two screws (2), see page 2-3.
A grease nipple is located at the top of each of the pulley sets. Press the grease through the grease nipples until the
grease gun feels hard, or until grease is pressed out between the shaft and the pulleys.
Replace the top cover and remember to replace the two screws securing the cover.
The lid must be mounted before starting the mixer.
Start the mixer and set the speed back to low.
Stop the mixer and fill the grease gun with new grease to be prepared for the next lubrication.
TYPES OF GREASE:
Grease for the shafts of the pulley sets: Lubriplate 1200-2, or another ball bearing grease: NLGI1 or NLGI 2.
When repairing the planetary head (which is greased for life) the grease (PN 868VH) should be used in the gear wheel,
gear wheel rim. The needle bearings of the planetary head should be greased with PN Sapphire 2 The needle bearings
must not be greased with the PN 868 VH type of grease.
Use only this type grease and do not mix with other types of grease.

that the bowl is placed correctly and the
bowl clamps are used.
pulling the handle forward. Ensure that the
bowl is placed correctly while the bowl is
lifted. Close the bowl screen.
Push the speed selector lever to obtain
the required speed. The speed must be
changed only when the mixer is
running.
Set the time required by turning the timer to Start the mixer by pressing the green start

Before the mixer is stopped, the speed
selector lever should be moved to the low-
est speed. The mixer must not be started
when loaded in high speed position.
Stop the mixer by pressing the red stop
button.
Recommended maximum speeds
OVERLOADING: Do not overload the mixer. Tough and heavy doughs might reduce the working capacity of the mixer by 75%. The
capacity will be further reduced if the speed of the tool is increased beyond what is recommended, or if a wrong tool is used. Big
lumps of grease or cooled ingredients must be divided into fine particles before being placed into the bowl. A long period of overload-
ing will cause the thermal overload relay to stop the mixer. Let the mixer rest for approximately three minutes and press the RED
STOP button BEFORE pressing the GREEN START
button.
If the mixer is stopped in high speed when loaded, the bowl is to be removed from the mixer and the speed set to low speed before
the bowl is placed in the mixer again.
WARNING: Bodily harm could result from placing hands into the bowl while the mixer is running.
