De-liming

Lime (scale) deposits are the result of minerals contained in the water feeding the dishwasher and appear as a white haze on the surface of the dishwasher. Severe scaling can appear as a granular deposit. These deposits are a result of the mineral content in the geographic area of the machine's location.

WARNING: Death or injury can result from toxic fume when de-liming agents come in contact with Chlorine Bleach, or other chemicals that contain iodine, bromine, or fluorine.

USE EXTREME CAUTION WHEN HANDLING ANY DE-LIMING AGENT

CAUTION: De-liming agents can cause chemical burns. Wear rubber gloves, eye protection and any other protective clothing as instructed by a qualified chemical supplier and follow the instructions provided by the chemical supplier.

! A TTENTION !

Place a flat-bottom dish rack upside down on the idle pump start switch at the entrance end

of the dishwasher to keep the dishwasher running during the de-liming procedure.

E-Rack Digital Temperature Display Meters

Digital Display

ATTENTION:

The Digital Temperature Displays only indicate temperature, they do not control booster heaters. Electro-mechanical thermostats continue to control the tank and final rinse heat circuits.

1. The analog temperature gauges have been replaced with digital temperature display meters.

2. The meters display temperatures for the prewash tank (if equipped), the wash tank, power rinse tank (if equipped), the DR dual rinse tank (if equipped), and the final rinse.

3. A meter displays temperature in 2 ways: a. The first display is a semi-circular LED bar that moves from left to right; as the temperature increases in magnitude. The color of the bar changes from black, to orange, and to green. b. The second display is a 3 digit LED that changes from OFF if the tank or final rinse heat is disabled, to Blank and from a minimum temperature of 70 temperature set point of the meter. (Refer to the "Display Meter Operation Checks" on the next page to change a Meter set-point.)
