N.B.: If you make use of chlorinated sanitizers, it is always advisable the employment of
an automatic dispenser with feeler for the measurement of the detergent
concentration, because brownish spots can form on the surfaces due to chlorine reactions
when pouring the detergent directly into the tank.
In any case the product shall be introduced near the pump suction pipe in the tank and at
least 15 cm far from the bottom in order to avoid corrosion.
Choice of the suitable cleansing agent is an essential condition if you want to obtain
extremely good washing results as concerns hygienic results.
It is then important to consider some points.
First of all only highly alkaline and chlorine-active antifoam products, especially made for
industrial dish-washing machines, must be used and they must be produced by well known
reliable Firms. We provide a short list just as an indication: Ecolab-Soilax; Henkel; Lever;
Diversey; Relativ.
Mean concentration of the powder cleansing agents must be 1,5-2,5 g/lt.
Mean concentration of liquid cleansing agents must be 2-4 g/lt.
In order to avoid scales and corrosions, put cleansing agent above water level on the
nearest area of the sucking pump filter, in this way it will immediately dilute and will not
deposit on the tank bottom.
6.3 - DESCALING
When hard water is used you can find, inside the machine and also on objects, calcareous
sediments which must be removed both for hygienic and operating reasons by a descaling
operation.
Operating process and frequency of this intervention are suggested by your cleansing agent
supplier who has suitable products, generally containing phosphoric acid.
In order to avoid damage to the machine do not increase the quantities and once operations
end rinse abundantly.
6.4 - HYGIENE
At last each 30 days it would be useful to do this operation which guarantees the complete
hygienic conditions of the machine. We suggest to contact your cleansing agent supplier
who will give you quantity and name of the most suitable product you can use and that,
generally, is an active chloride powder (100-200 ppm).
In order to avoid damage to the machine do not increase the quantities and once operations
end, rinse abundantly.
