RINSE-AID PUMP

This model has an automatic rinse-aid pump for use with a container of liquid rinse-aid. The rinse-aid pump is

a peristaltic regulated (looks exactly like the detergent pump) and can be regulated by a screw above and on the right of the glass cover. The regulation can be from 0 lt/hour to 0,7 lt/hr.

Both pumps are mounting vertically on an inox bracket on the left of the booster and are marked with two yellow stickers.

Before you perform these adjustments, turn off the power supply.

The dozer is adjusted from the manufacturer’s premises at its maximum value for easy initial priming and must be adjusted accordingly (depending on water hardness, how dirty the dishes are, and the detergent used).

To reduce (-) the amount of rinse aid, turn the center screw clockwise. To increase (+), turn counterclockwise.

Note: this is a 15 revolution adjusting screw to provide ne adjustments as required.

Suggestion for initializing personnel: After priming system by operating machine through several cycles,

rotate adjusting screw gently to full closed position (clockwise) and adjust (counter-clockwise) about 7

full revolutions. Empty wash tank and rell with fresh water. Operate for two or three cycles and verify concentration level. Adjust dozer again if required to achieve nal desired results.

Installation

AUTOMATIC FILLING OF DETERGENT

This model has an automatic detergent pump for use with a container of non foaming liquid detergent. The

detergent pump is a peristaltic regulated (looks exactly like the rinse-aid pump) and can be regulated by a screw above and on the right of the glass cover. The regulation can be from 0 lt/hour to 3,0 lt/hr.

MANUAL FILLING OF DETERGENT

Use only non-foaming detergent suitable for commercial dishwashers. In the event of non use or malfunction of the automatic detergent injection system, put the detergent suppliers recommended amount directly into the wash compartment tank after the machine has reached its operating temperature.

The correct dosage depends on the water hardness and the amount of residue on the dishes. Follow the detergent manufacturer’s recommendations. Less detergent deters good washing results and more detergent usually does not provide better results, but rather more unnecessary consumption and environment pollution.

picks, etc., before placing the dishes in the basket.

If washing is delayed we recommend that you soak dishes and/or glasses which have food residues.

FILLING OF BASKET

Place glasses and cups, with the opening facing down and not piled one on top of the other, in the appropriate baskets. Glasses should not touch each other (damage to glass or stains due

to contact may occur).

Plates should be stacked vertically in appropriate baskets and not touching each other, look to

the side of the baskets to see the recommended loading capacity.

Place tableware in the supplied plastic basket, with handles downwards or placed freely in

a level plastic basket.

In every case, avoid overloading the basket.

MAINTENANCE / CARE / REPAIR

Proper operation and safe use may be ensured only through the

correct use of the appliance, as well as the compliance with the

operation instructions, the corresponding specications and the care

and cleaning indications.

Notice: Before maintenance, other than daily interior cleaning, power and water supply to the machine must be turned off. The appliance should never be sprayed with water or high pressure cleaning solution, because any water or solution in the electrical elements will affect operation of the appliance as well as provide a potential for serious electrical shock.

No safety systems should be disabled.

20

REGULAR MAINTENANCE AND CLEANING.

Depending on local water hardness, the nozzles on the upper wash piping and rinse arms should be cleaned. Caution must be exercised to not damage the nozzles. If rinse nozzles are removed, they must be replaced with the slot in line with the rinse arm. ATTENTION MUST BE

GIVEN TO THE CORRECT INSTALLATION OF FILTERS, WASH ARMS, AND TEFLON BUSHINGS! REPLACE BUSHINGS IF WORN. Clean the

appliance with warm water and conventional cleaning aids. Stainless steel parts should never be cleaned them with “steel wool” wire brush, etc, since even the lightest contacts on the surfaces with steel may contaminate the stainless steel and cause rust formation. Use brushes made of polymer plastic or natural bristles or thin brass wire. Always keep brush movements in line with grain in the Stainless Steel so that you will not affect the appearance. Finally, rinse with clean water and dry thoroughly.

We remind you that corrosion (rust formation) on stainless steel surfaces is not created by itself, but rather due to the use of improper cleaning products (e.g. whitening or particularly caustic cleaning products based on chlorine). Occasionally calcium sediments form on the internal walls of the wash compartment, tubing, and booster chamber (due to mineral particles in the water), which may affect the correct operation of the appliance and

which requires removal.
