2Description
This chapter contains an explanatory description of the machine, which is the background information
that is required to correctly and safely use the machine.
2.1 General
The rotation of the mixer shaft and the mixing disc sets the liquid in the reservoir in motion. The
mixing disc takes in the liquid from above and then sends the liquid downwards and to the side via
the channels in the mixing disc. In the disc there are 3 channels towards the bottom of the disc and 3
channels directly to the side of the mixing disc. This causes the liquid to move as shown in Figure 3.
The standard direction of rotation of the mixing disc is clockwise (viewed from above).
Figure 3: Position of the mixing disc
2.2 Operating principle
The Enmix Light construction comprises a motor and an extended shaft to which a mixing disc has
been attached. The shaft can be customised to fit every fertilizer bin or other container of liquid
substances shorter or shallower than 140 cm. The mixing disc must be mounted at least 10 cm from
the bottom and must be able to rotate freely while submerged in the liquid.
The material used is predominantly stainless steel type 316 and POM black. When working with low
pH values (under pH4) or with other stronger chemicals ensure beforehand whether the material is
sufficiently resistant to these chemicals.
The shaft is not supported. Because the mixing disc propels the liquid in two directions (downwards
and sideways) and from the centre (from the top), the shaft remains balanced.
It is recommended to check the mixing disc once a month to ensure that it is not clogged.
2.3 Transport and storage
The Enmix Light is transported and should be stored in special packaging. The Enmix is transported as
a complete product, the shaft length should be adjusted at the end-user by an approved installer.
When storing the Enmix Light, care must be taken not to allow the mixer shaft and, where
appropriate, the shaft guide to bend.

4Assembly
4.1 General
The Enmix Light is an unfinished product, and consequently the manufacturer cannot install all the
required safety devices such as control logic or an emergency stop. It is, therefore, important that the
approved installer takes care of these requirements.
4.2 Installation instructions
Please make sure that the Enmix Light is out of reach of children at all times.
Advice with regard to dosage rates and types of fertilizer should be obtained from your supplier.
•Make sure the fluid reservoir which the Enmix light is mounted to is placed on a stable surface.
•Make sure that the Enmix Light is firmly attached to the fertilizer bin or container.
•Make sure at all times that the mixing disc can rotate freely.
•Make sure that contact with the agitator-mixer is prevented by placing a safety grid or lid on the
fertilizer bin or container.
During each phase of the assembly the approved installer or the user must ensure that he or she can
work safely. The use of a stepladder or the helping hand of an extra person or persons will make
assembly of the machine easier and safer.
4.3 Delivery checklist
Make sure all components have been delivered prior to commencing assembly. The Enmix light will be
assembled at the supplier before shipping. At every batch of Enmix light there will be an assembly
manual attached.

▪Use the pre-drilled holes in the mounting plate to mount the Enmix Light.
oIn a round bin or container, the water sometimes turns and swirls in one direction instead
of mixing. In consultation with the manufacturer, place a dividing plate in the bin or
container to prevent this from happening or position the Enmix Light away from the
centre.
oEnsure the Enmix Light can be mounted safely onto the bin or container.
▪Request assistance and use practical aids such as a stepladder or a footstool.
−Mount the Enmix Light onto the bin or container.
−Make sure the mixer is fitted with a safety guard and poses no danger to people!
oUse a cover or grid or any other appropriate guard.
−Assemble the mixing disc following Figure 3 and Figure 4. If the assembly of the mixing disc is
done in the wrong way, the fluid can be sprayed upwards. This could create dangerous situations.
4.6 Connecting / start-up
−Check that the Enmix Light is securely mounted.
−Check that the motor and mixing disc are firmly attached to the mounting plate.
−Check that the shaft can rotate freely.
−Check that the mixing disc can rotate freely.
oMake sure there are no obstacles in the way of the mixing disc.
−Make sure that the mixing disc is mounted at least 100 mm from the bottom of the bin or
container.
−Fill the bin or container with liquid up to at least 100 mm above the mixing disc.
−Make sure the mixer is has a safety guard and poses no danger to people!
−Insert the plug in the socket.
oThe Enmix must be within view of the socket outlet.
