MACHINE DESCRIPTION
The main features of an INDUSTRIAL DISHWASHER, unlike those of a DOMESTIC DISHWASHER, are different in their
ability to wash big volumes of ware in a very short period of time. This requirement means that the design of an industrial m achine is considerably different. Certain key paramaters of an industrial machine differ by:
The capacity of the basket;
Features of the type of dishwasher;
An industrial dishwasher can operate better when using demineralized water, with no impurities. In case this won’t be possi-
ble, a soft or softened water supply should be used (no calcium, magnesium in the water);
AISI304 heavy duty stainless steel boiler and machine construction;
Automatic washing and rinsing system;
Automatic water filling controlled by pressure switch;
Thermostatically controlled wash and rinse temperature;
Possibility to rinse glassware with cold water;
Possibility to stop the cycle by opening the door;
Automatically rinse aid pump;
Incoloy tank and boiler elements.
ELECTRICAL SAFETY REQUIREMENTS
Before any cleaning or maintenance, when required, press the switch 0/1 on the position 0 and switch off electrical pow-
er at the switch, turning it to OFF.
Do not replace the electrical power cable from the one provided. In case the power cable requires to be replaced, contact a
qualified electrician to replace it by a similar cable, Y Type.
Verify that the electrical values supplied to the machine meet with the demands as specified on the ratings plate of the
machine. If not, do not start the machine and call a technician.
Check that your electrical system complies with regulations and that the machine has been correctly earthed.
Do not open the door of the dishwasher while a cycle has been started. There is a danger of being sprayed by hot water.
Do not use the machine if the temperature around it is inferior than 5°C.

USER CHECKS
The following tests must be performed only by qualified personnel:
Installation and commissioning;
Water and electrical connection;
Adjustment of the rinse aid dispenser and the detergent dispenser (if fitted on the machine).
The user must perform the following checks every day:
Check the correct connection of the inlet and drain tube and that the water supply is open.
Check that the main electrical switch is ON.
Check the level of the product in the rinse aid bottle (and detergent, if the machine is fitted with a detergent dispenser).
Do not allow the chemical bottles to become empty. If required, replace the bottle and chek that it is correctly sucking
product.
ATTENTION
Respect all safety rules when using corrosive chemical products. We recommend the use of gloves and goggles.
Every time you change the product (detergent or rinse aid) it is ABSOLUTELY NECESSARY to clean the peristaltic
pump tubes by immersing them in water for some cycles.
ONLY USE PRODUCTS DESIGNED FOR INDUSTRIAL DISHWASHING.
We recommended replacing the peristaltic pump tubes at least every 12 months. Peristaltic tubes flatten over time and
dispense less product.
Failure to comply with these instructions will avoid the warranty on the machine.

OBSERVATIONS BEFORE WASHING
This machine was developed and designed especially to achieve energy savings. To further optimize the energy savings you can
observe the following suggestions:
Connect the machine to a hot water supply (max 50°C).
Use the full capacity of the baskets, without overloading them.
Follow the instructions of the chemical supplier.
If you use only a partially full basket, reduce the amount of detergent dosed accordingly (for hand dosed machines)
Before loading the dishwasher, observe the following:
Remove as much solid waste as possible, by hand, in order not to block filters, drain or jets of wash arms.
Pre-Flush with water, an overhead spray is better.
When washing items with soil of starch, protein blood, cheese, allow to pre-soak in COLD water before washing.
When racking, be sure that all soiled surfaces are exposed to the wash spray. Do not allow items to be “shielded” by other
items.
Insert the glasses and cups with the inside facing downward and do not overlap them.
Check that the upper wash arms are not obstructed and that are free to rotate.
For best results, we suggest you to wash glassware, cutlery and cups separately from plates with a different water used for
washing dishes.
Do not wash dishes or cutlery made of wood or with some wooden parts; in fact wood can warp and be damaged. In addi-
tion to this, glues used are not suitable for dishwashers; a consequence could be the detachment of handles or small parts .
Pots in copper, pewter or aluminum, or thin glasses, decorated or made of crystal can damage if washed by a glass/
dishwasher.
If the machine is not supplied with a detergent dispenser, hand dose the wash tank, referring to the chemical manufactur-
ers instructions.
Use only Industrial Dishwashing detergents.
We recommend using a liquid type of detergent.
For heavily soiled items, we suggest to rinse them with hot water.
ATTENTION
Do not wash plastic kitchenware.
ATTENTION
Observe all safety rules when using corrosive products. We recommend the use of gloves and goggles.

OPERATION
Open the dishwasher door and check whether the wash arms are installed. If not, install the wash arms (see Installation
Manual). Verify that the suction filter pump is properly assembled. Insert the "overflow" pipe in the case of gravity discharge or check the correct positioning of the drain pump filter. Then close the door.
FILLING AND HEATING:
1. Pressing the switch 0/1 (1) to 1, the indicator light (1a) will turn on and the machine will start a check of the light.
After that, the machine is in the stand-by mode and the light (2a) will flash.
2. Press the cycle button (2), the machine will starts filling with water.
3. After filling with water, the machine is ready for washing; this is the state of full machine.
4. In this state the machine has full control over the wash temperature and water heater tank. So, if the water temperature of the boiler is lower than the pre-set temperature, the element will turn on, until when the pre-set temperature is reached. The operation of the boiler heating element is indicated by the corresponding light (7a) which turns
on.
5. Once the temperature has reached the pre-set boiler temperature, the heater element is turned off and accordingly
the corresponding light will turn off (7a). If the water of the wash tank is lower than the pre-set temperature, the
wash tank element turns on until when the pre-set temperature is reached. The operation of the wash tank heating
element is indicated by the corresponding light (8a) which turns.
6. At this point, it is possible to start a wash cycle or cold rinse.
WASHING:
1. Press the cycle button (2), the corresponding indicator light (2a) turn will on.
2. Wait until when the machine has completed the wash cycle/hot rinse.
3. At the end of the cycle (light 2a off), open the door and remove the rack.
COLD RINSE BUTTON
1. Press and hold the cold rinse button (3). The indicator light will turn on (3a). The machine will rinse with cold water.
2. Switch off the cold rinse button (3). The corresponding indicator light will turn off.
ATTENTION
The initial operation of the dishwasher MUST be performed by authorized and qualified person who will check the func-
tionality of the machine.
ATTENTION
To achieve a good washing result it is essential to wait for the pre-set temperatures to be attempted. When the indicator
lights 7a and 8a turn off, heating has stopped and temperature has been reached.
ATTENTION
Do not open the door when the machine is working. In case the door is opened during the cycle, the machine will stop.
Automatically if you close the door, the cycle will continue from the point where it was interrupted.
ATTENTION
The machines can be equipped with a temperature Interlock. This device allows the machine to perform the rinse cycle
only when the set temperature has been reached. If the wash cycle has started before the rinse boiler heating lamp (7a)
has switched off, then the machine will prolong the cycle, until when the set temperature is reached.

ATTENTION
If you need to clean the tank, avoid using steel wool, ferrous or abrasives, or liquid detergents which are not suitable for
cleaning stainless steel. Do not the use chlorine-based substances to avoid oxidizing the stainless steel (for example,
bleach, or similar).
When cleaning the tank always wear rubber gloves.
Check that there are no pieces of glass or ceramic that could damage the pipes in rubber.
Remove the filter basket only after rinsing the tank.
Change the water in the tank at least once a day and whenever excessive soil or dirt are inside the wash water.
Cleaning wash tank water will perform better cleaning results.
