CLEANSING AGENTS
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. Mean concentration of the cleansing agents in powder must be 1,5-2,5 g/lt.
Mean concentration of liquid cleansing agents nust 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.
DESCALING
When hard water is used you can find, inside the machine and also on dishes, 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.
SANIFICATION
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.
USEFUL HINTS OF STAINLESS STEEL MAINTENANCE
Stainless steel is so called because it is not affected by oxidation,this is due to a thin molecular layer of oxide
on the surface which protects againts further oxidation. There are, howevwr, substances which can modify or
destroy this layer,giving rise to corrosion:besides preventing the protective film of oxide from reforming,these
substances corrode the stainless steel itself and can cause irreparable damage. It is therefore necessary to
prevent this by choosing correct cleaning products and by complying with the following simple
recommendations:never forget that when using these appliances,the first and fundamental rule is to
guarantee that the cleaning products are both non-toxic and hygienic.
Before using any detergent to clean either the stainless steel or the immediate and sorrounding floor area,
always ask your supplier for the most suitable product which does not cause corrosion on the steel itself; the
onset of rust is most commonly caused by the use of unsuitable cleaning materials (strongly acid chlorate
based detergents) or on inadequate maintenance.
Our appliances are made of stainless steel AISI 304 (18-10 type) for exterior panelling,upper tops,tanks etc.
Comply with the following instructions when cleaning and servicing parts in stainless steel.
Ordinary daily maintenance
Carefully and frequently clean the surfaces using a damp cloth; use soap and water or normal detergents,so
long as these do not contain abrasives or chlorine based substances such as sodium hypochlorite
(bleech),hydrochloric acid or other such solutions:These products quickly and irreparably corrode stainless
steel. When cleaning floors underneath or near the appliances, never use the above mentioned products as
vapours or splashes could subject the steel to similar destructive effects.
Only ever rub in the direction of the satining, then thoroughly rinse with clean water and carefully dry.
Rust : water supply pipes, inevitably convey particles of rust dissolved in the water especially in new
installation plants or when taps are opened after a period of inactivity. These iron deposits must not be
allowed to remain on the stainless steel since they produce rust by contamination.
Use suitable products to remove any rust marks,from companies which produce detergents for industrial
use. After application, thoroughly rinse with clean water, neutralizing the action of the product with an
alkaline detergent normally used to clean such appliances or with another specific product.
DO NOT USE METAL MATS TO CLEAN THE STAINLESS STEEL
