supply has been removed, wait until the
machine has reached room temperature,
before working on it.
-Never leave tools, parts or other loose
material in or on the machine;
-Chek that there are no rusting foreign
bodies, because of the material “stainless
steel” could begin to rust. Rust particles can
come from non- stainless steel dishes or
damaged wire baskets.
- Do not wash the machine and the
area surrounding it with fire hydrants, steam
jets of high-pressure cleaners;
- When clearing the floor be careful not
to saturate the base of the machine, in order
to avoid a prolonged stagnation of water;

use a brush or a soft cloth;
- To clean the machine do not use
abrasive cleaners;
-BEFORE starting machine or cycle,
after any maintenance or repair work,
make sure all protectives are correctly
installed;
Please pay attention to the opening and
closing of the door of the machine. Do not use the
machine if you are wearing clothes/items that could
get entangles in the dishwasher parts. As they can
limit personnel’s regular moving ability!
DAY MAINTENANCE
Attention. Before carrying out cleaning
the inside of the machine, make sure that there
are no foreign objects that could damage the
rusty steel inside the tank. The eventual rust
particles could come from non-stainless steel
dishes, from baskets or damaged water pipes
not rust-proof.
- Disconnect the machine with
pushbutton "A";
- Lift the overflow pipe and let the
water drain out of the tank;
- Wash thoroughly the tank and the
filters housing to remove all
impurities;
- Take the filters and clean it under
running water;
- Re-assemble the overflow pipe and
the filters in their housings;

-Clean the filter of the steam condenser
that is placed in the upper part of the
hood;
(only for machines with steam
condenser!)
- Clean the outer surface of the
machine by using a wet sponge; don't
use water jets because, beside being
dangerous they could damage the
electrical parts; don't use abrasive
detergents;
- When the machine is to remain idle
for a long time, drain all the water
from the boiler (the drain
plug is located on the lower
side of the boiler) and from the
electropump. Also leave the wash
tank open.
NEVER WASH THE EXTERNAL PART
OF THE MACHINE WITH A WATER JET

DAILY CLEANING OF THE INTERIOR OF THE POT-WASHER

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!
