Accessory Assembly/Disassembly; Filling And Draining The Detergent Solution Tank; Draining The Recovery Tank - Comet CRS 90 BT Manual De Instrucciones

7.3 ACCESSORY
(BRUSHES, PAD DRIVERS AND ABRASIVE DISKS)
• Never use the machine if brushes or pad drivers and
abrasive disks are not perfectly installed.
Assembly:
Make sure that the brush plate is raised; otherwise lift
it by following the instructions provided in the speci-
fic section.
Make sure that the ignition key on the control panel
is in position "0".
Bring the brushes (or the guide disks equipped with
abrasive disks) near the connections, under the brush
plate; lift them, bring them through the centering
flange, and turn them opposite the rotation direction
until you hear the stable "click" connection.
• Do not allow the length of the rows of brushes to
become lower than 1 cm.
• Do not allow the thickness of the abrasive disks to
become less than 1 cm.
Working with excessively worn brushes or excessively
thin abrasive disks may damage the machine and the
floor.
Regularly check the wear on these parts before star-
ting to work.
Disassembly or replacement:
Make sure that the brush plate is raised; otherwise lift
it by following the instructions provided in the speci-
fic section.
Make sure that the ignition key on the control panel
is in position "0".
While holding the brushes (or the guide disks) with
the hands under the plate, turn them in the rotation
direction while lowering to release them from the gui-
de plate.
7.4 FILLING AND DRAINING THE DETERGENT
SOLUTION TANK
☞ The temperature of the water or the detergent
should never exceed 50°C.
☞ Always empty the detergent solution tank be-
fore filling it up.
To fill the solution tank:
• Remove the plug in the back of the machine.
• Leave 7 cm between the mouth of the plug and the
liquid level. Do not fill beyond this point!
• Add the required quantity of the chemical product,
considering the percentage indicated by the supplier,
with reference to the full tank capacity listed on the
product sheet.
• Use only those products suitable for the floor and the
dirt to be removed.
•
The machine was designed to be used with non-
foaming and biodegradable detergents made specifi-
cally for scrubber-driers.
The use of other chemical products (such as sodium
hypochlorite, oxidisers, solvents or hydrocarbons)
may damage or destroy the machine.
• Follow the safety regulations specified in the relative
section and indicated on the detergent container.
ASSEMBLY/DISASSEMBLY
• Contact the machine manufacturer to obtain a com-
plete list of available and suitable detergents.
•Always add the detergent after filling the tank with
water to prevent foam from being created inside.
• Do not leave the water hose unattended and insert
it completely into the tank: the hose might move and
get sensitive parts of the machine wet.
• Close the tank cover.
To drain the solution water tank:
• Open the valve located at the bottom of the machine
in the back ( Photo B - 5 ; Photo Q - 3 ) and wait until
the tank has been completely emptied.
• Close the drain valve.

7.5 DRAINING THE RECOVERY TANK

The dirty water must be drained in accordance with
national regulations.
The user is completely responsible for ensuring com-
pliance with such rules.
After the detergent solution is finished, always empty
the recovery tank before filling it again.
In general, the recovery tank can be emptied whene-
ver required, and even during intermediate phases of
the work cycle.
•
Always empty the recovery tank before lifting it
to avoid health problems for operators and to avoid
damaging the machine.
The recovery tank volume is higher than the deter-
gent
solution volume, therefore a potentially dangerous
situation for the suction motor should never occur. In
any case, a safety float turns off the suction motor if
the dirty liquid level is too high.
•
If water or foam starts leaking from under the
tanks for any reason, immediately turn off the suction
motor and empty the recovery tank.
To drain the tank:
Drive the machine to a suitable location to drain the
dirty water and preferably near a toilet or a sewer
drain (comply with the national regulations for waste
water disposal).
Turn off the machine and remove the key from the
panel.
Detach the drain hose from the hook and, keeping it
high, unscrew the plug.
Lower the drain hose toward the selected drainage
point.
The emptying operation can be interrupted quickly
and whenever required just by raising the drain hose.
Check the quantity of residual dirt in the tank and, if
necessary, clean the interior through the inspection
hole, lifting the cover and the funnel at the top.
Carefully position the funnel inside the inspection
hole and close the top cover, tightening the lock
handles after each inspection/cleaning operation.
Fully tighten the drain hose with the screw plug and
hang it on the support behind the machine.
☞The top cover of the tank and the drain hose plug
must be airtight, otherwise the subsequent pressure
loss will reduce drying efficiency.
