SERVICE MANUAL
EVO FRONT LOADING DISHWASHER
8.4. CHEMICAL DISPENSERS´ CONNECTION
All machines come equipped with an internal rinse dispenser.
The detergent dispenser is optional in some models and is supplied as standard in
others.
All the dispenser tubes must be full before starting to adjust the dispensers.
To access the dispensers and adjust them, first remove the front cover of the
appliance. Adjustments must be made at machine operating temperature.
The following installation and adjustment must be carried out by authorised and
qualified personnel. Contact a qualified chemical product supplier to determine the most
suitable product and dose in order to optimise the wash.
The guarantee does not cover damage caused by the incorrect installation or use of
dispensers and chemical products.
The correct selection and dosing of detergent and rinse aid is essential for obtaining an optimum wash. Only use
liquid detergent especially designed for use with industrial dishwashers and which is non-foam forming at high
temperatures. Detergents designed for domestic use should not be used under any circumstances.
The detergent and rinse aid containers must be placed close to the appliance. The results of the wash should be
assessed after two fills and at least three wash cycles in order to stabilise the doses. There should not be any foam
in the tub after running the cycles.
Scratched dishes and the formation of foam in the wash solution are usually an indication of excess rinse aid.
Dishes with too many water drops or which are slow to dry are usually a sign of insufficient rinse aid.
Contact a chemical product supplier to determine the most suitable product and dose in order to
optimise the wash.
The guarantee does not cover damage caused by the incorrect use of dispensers and chemical products.
When handling chemical substances, the product safety instructions and recommended doses
must be observed. Use protective clothing, gloves and safety glasses when handling chemical
products.
Do not mix different detergents.
Correct selection and dosing of detergent and rinse aid is essential for obtaining an optimum wash.
The quantities/doses recommended by the detergent/rinse aid supplier must be observed.
Check and maintain the levels of detergent and rinse aid in the containers; always
check the levels at the start of every workday.
Make sure that the weight and filter are correctly fitted on the ends of the rinse aid
and detergent intake tubes and that they are correctly immersed in the correct
containers.
Clean the filters regularly to prevent blockages.
Each tube has a label on the end indicating «Rinse Aid» or «/Detergent» to identify them; the blue tube is for rinse
aid and the clear tube for detergent.
Place the containers close to the appliance.
IMPORTANT
Do not mix different detergents or rinse aids as they could crystallise and damage the dispensers. Whenever the
type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to clean and bleed the dispenser and its
hoses, by placing the detergent/rinse aid pipe in water for several cycles.
If the rinse aid or detergent is changed, the settings should be adjusted accordingly by qualified personnel.
