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.
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 nozzle 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 nozzle and the pump pressure.
A step that uses compressed air to "blow free" the spraying line and spray nozzle is
automatically performed in the program sequence. This step uses the last seconds (adjustable)
of the spraying time; valve Y375 for the compressed air line opens. 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
the sprayer 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 put too much
into the cleaning machine. 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 supplier of chemical additives can help you to make the exact adjustment.
* This program also includes cleaning of the tanks!
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.
