DETERGENT and RINSE-AID
Attention. During the use of chemicals is advisable to wear appropriate clothing, such as gloves
and protectives glasses.
It’s therefore important to consider some factors.
Firsf of all, it is necessary to use only strongly anti-foaming Alkali and Chlore Products specific for
industrial dishwasher, manufactured by Companies recognized as seriousness. By way of illustration, we
list a few: Ecolab-Soilax; Henkel; Lever; Diversey; Relativ.
Detergent
The detergent s needed to remove dirt and food from the dishes.
The detergent may by determined in various ways:
- Manually if powder
- Automatically from one external box via a dosing device embedded or external.
The mean concentration of powder detergents should be of 1,5÷2,5 g/liters
For dosing instructions refer to the initial notices before washing.
If automatic, always check the presence of liquid in the tanks and set the dosages by the installer.
.
The mean concentration of liquid detergents should be of 2÷4 g/liters.
In order to avoid corrosion and scalling, the placing of the detergent must be made above the water level in
the area closest to the pump suction filter, so that it enters immediately in solution and does not deposit on
the tank bottom.
The detergent dispenser is not standard on all the machines.
Then check the presence of it in the order data.
Periodically check the presence of product in external tanks!
Rinse-aid
To ensure proper rinsing and fast drying and prevent scale deposits on the dishes, you need to add to the
water an additive such as a surfactant (Rinse-Aid)
The rinse-aid is dosed automatically and its dosage is set by the authorized service technician.
The average concentration of use is of 0.15 g/liter.
The supplier of detergent will be able to recommend the most suitable product.
The machine is equipped with rinse-aid dispenser.
Periodically check the presence of the products in the external tanks!

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 least 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 is generally 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.
ATTENTION: Observe the safety notes and dosage data for the use of chemicals. During the use of the
chemical substance wear protective clothing, gloves and glasses. Do not mix different cleaning products.

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 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

Setting of fan’s stop time
(Only for machines with steam condenser CVP)
At the end of the washing, the steam suction fan starts running automatically. The suction continues for a
time that can be programmed from 5 to 80 seconds after the rinse end .
As default, the fan’s functioning time is programmed for a 20’’ duration from the ending of the final rinse at
every wash cycle.
It’s anyway possible to program the duration of this phase according to one’s own requirements.
After having programmed the seconds for the additional functioning of the fan, configure the dip-switch on
the PCB board, that is inside the control box, by following the instructions below.
