AUTOMATIC CAP
The Eureka dispenser is equipped of an automatic
cap, necessary to avoid the exsiccation of the
colorants. Set the “suck back” function with the
software parameters in the correct way, to avoid problems of contamination or dripping of
colorant. The cap, with a completely automatic process, open before each dosage and
close at the end of it; with this device the possibility of exsiccation of the products is largely
reduced. The part of the cap containing the sponge is simply extractable, so the operation
of cleaning results very rapid, as shown in the pictures below.
Inside the cap case there are two micro-switches that control the two positions of the
automatic cap. The automatic cap have been engineered to be simple and rapid to extract.
In case of substitution, disconnect the power supply connection and pull the cap in the
sense of the front of the machine; the fixing hooks will release and the cap will slide out.
Now the new automatic cap can be positioned and fixed without using any tool.
Is very important to keep the sponge clean and humid to preserve the good working
