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

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.
