On consignment of the machine
When the machine is consigned to the customer, an immediate check must
be performed to ensure all the material mentioned in the shipping documents
has been received, and also to check the machine has not suffered damage
during transportation. If this is the case, the carrier must ascertain the extent
of the damage at once, informing our customer service office. It is only by
prompt action of this type that the missing material can be obtained, and
compensationfor damage successfully claimed.
Introductory comment
INNOVA 2011 is a scrubbing machine that is able to clean a wide variety of
types of flooring and types of dirt by using the mechanical action of two disc
or cylindrical brushes, depending on the model, and the chemical action of a
water-detergent solution. As it advances, it also collects the dirt removed and
thedetergent solution not absorbed bythe floor.
The machine must be only used for this purpose. Even the best
machines will only work well if used correctly and kept in good working order.
We therefore suggest you read this instruction booklet carefully and read it
again whenever difficulties arise while using the machine If necessary,
remember that our customer assistance service (organised in collaboration
with our dealers) is always available for advice or direct intervention.
Intended use
The scrubbing machine is exclusively designed for the professional cleaning
of surfaces and floors in industrial, commercialand public environments. The
machine is only suitable for use inclosed(orat least covered) places.
The machine is not suitable for use in the rain, or under water jets. It is
FORBIDDEN to use the machine for picking up dangerous dusts or
inflammable liquids in places with a potentially explosive atmosphere. In
addition, it is not suitable as a means of transport for people or objects.

28. DETERGENT ADJUSTMENT (VERSIONS WITHOUT CDS)
Firstly, fully open the outflow of the tap, by means of the lever (3) on the steering column. During the first
few meters, check that the amount of solution to wet the floor is sufficient, but not too much that it exits the
splash-guard, the adjustment of the detergent application is made by means of lever (3) (shifting it
downwards increases the flow, shifting it upwards decreases it). Bear in mind that the correct amount of
solution is always depends on the nature of the floor, the degree of dirt and the forward speed.
29. REGULATING THE DETERGENT (VERSIONS WITH CDS)
Firstly, fully open the outflow of the tap, by means of the lever (3) on the steering column. Position the
water flow adjustment knob (1) on zero. Position the detergent adjustment knob (2) on zero. By pressing
the accelerator pedal the brushes start, the machine begins to move and the detergent is distributed.
During the first few meters:
1. Regulate the flow of detergent solution to the brushes by rotating the knob (1) clockwise. The quantity
of solution varies from a minimum of 30 litres/hour to a maximum of 75 litres/hour, with 7 set
measurement points. The right solution flow should be proportional to the degree of dirt on the floor.
In addition, remember that the time available for continuous working depends on the quantity of water
in the tank: for example, work autonomy with a full tank (about 85 litres) and the selector (1) on 30 is
about 3 hours.
2. Regulate the percentage of detergent in the solution by rotating the knob (2) clockwise. The lower
value is equal to 0.5% (for standard detergents) or 0.1% (for a concentrated detergent, diluted as
indicated on the label supplied with the machine), while the higher value is equal to 3.5% or 0.7%,
with 7 set points. Use high detergent percentages to remove very greasy dirt from the floor.
When you have finished regulating the quantities, you can remove the knobs and cover the holes with the
rubber caps supplied.
WARNING: If the CDS system does not work, or you want to clean without using this device, you can
intervene on the tap (3) on the brush head near the solenoid valve, rotating the lever by 180° as shown in
the figure. Rotate the knobs (1) and (2) anticlockwise, to “OFF”.
ATTENTION: before regulating the solution, check there is detergent in the inner can, and that the side
water tap is turned on.
To avoid any tampering with the set regulation, you can remove the two switches and cover the two holes
with the plastic caps supplied with the machine.
To resolve any malfunctioning of the CDS system, contact the COMAC assistance centre.
WARNING: By positioning the tap lever in this way the CDS dosing system is excluded and the detergent
solution is deposited on the brushes. Rotate the knobs (2) and (3) anticlockwise, to the “0” position.
WARNING: By positioning the tap lever in this way, the detergent solution is not distributed on the
brushes. Rotate the knobs (2) and (3) anticlockwise, to the “0” position.
WARNING: By positioning the tap lever in this way the CDS dosing system is activated.
