Working method
The complete process for carpet professional cleaning is carried out through 3 steps:
A. Carpet pre-spraying, with a concentrated solution of water and chemical
B. Cleaning with injection-extraction method, using a solution of water and chemical.
C. Cleaning with injection-extraction method, using clean water only, rinsing carpet
surfaces and removing therefore any chemical residual as well.
STEP A
– PRE-SPRAYING AND CHEMICAL ACTION
1.
Open the chemical input valve on the regulation panel.
2.
Check that the pre-spray gun is connected to the machine with the pre-spray hose.
3.
Switch on the solution pump, by acting on the pump switch, located on the control
panel.
4.
To spray the solution, press the lever on the pre-spray gun. Pull backwards the spray
nozzle, located in the terminal part of the gun, in order to spray with the correct
pressure. The position with nozzle pushed forward may be used to accelerate the pump
priming when starting work, with the pre-spray hose still empty.
5.
By rotating the nozzle, it is possible to adjust the spray angle. Spray the chemical
product uniformly on the carpet. Spray more chemical on spots.
6.
During pre-spray, the machine automatically regulates the chemical concentration to a
value which is optimal for pre-spray.
7.
After pre-spraying, store the pre-spray pipe and gun and connect the carpet wand to
the machine.
TIME NECESSARY FOR THE CHEMICAL ACTION
It is enough to leave the chimical act for 2-3 minutes on carpet. Therefore, after pre-spraying
an area, it is normally possible to proceed immediately with carpet extraction cleaning.
STEP B
– EXTRACTION CLEANING WITH CHEMICAL SOLUTION
•
Check on the regulation panel that the chemical input valve is open.
•
Proceed with extraction cleaning, using the carpet wand. The chemical concentration is
automatically set by the machine, to a value which is optimal for extraction cleaning with
chemical solution.
In some cases, it is possible to avoid extraction cleaning with chemical and directly proceed
with cleaning with clean water only.
