Sprayer operation
The computer controls the sprayer.
Use only products that remain liquid at room temperature.
Attention: Watch the liquid level in the product container.
The pump should not run when it is dry!
Use only suitable chemical additives.
Then enter the number of the waterproofing program, press the "START" button; the spraying
time, which you can change, if necessary, appears in the display field. Press "E" to start the
program.
The system suctions the product from the product container and passes it through the open stop
valve (369); the system feeds the product through the spray pump to the spray nozzles in the cage
via the non-return valve and then sprays the garments.
The flexible suction hose is shaped into a tube at one end so that the suction line always reaches
vertically down to the bottom of the product container. A fine sieve with suction valve is located at
the suction opening.
The total spraying time determines how much of the product is sprayed, according to the
throughput capability of the spray nozzles and the pump pressure.
A step that uses compressed air to "blow free" the spraying line and spray nozzles is automatically
performed in the program sequence. Also valve Y375 for the compressed air line is then opened
for 30 seconds. When the "blow free" step has completed, the spray pump turns off and valve
Y375 closes.
Before longer standstill times or before you change the product, we recommend that you rinse with
solvent. This should prevent the sprayer from becoming gummed up with product residues.
Do this by starting program P50. For the duration of the spraying, the stop valve (369/1) is open,
so that solvent from the clean tank is suctioned in for rinsing instead of the product.
In order to achieve a good waterproofing effect, make sure not to overload the
cleaning machine with garments.
It is useful to apply the amount of product to the number of garments instead of to
the weight.
The recommended value is 40 ml of product for waterproofing each garment
piece. Please refer to the datasheets from the appropriate manufacturer for the
exact amount.
The machine uses a 1.5 nozzle; an additional 2.5 nozzle is included in the delivery.
Your chemical additives supplier can help you to make the exact adjustment.
Note:
On request the probes for the containers with auxiliary agents can be supplied at the same time.These
will give information in good time, when the containers are to be replaced.
