De-liming

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 the result of the mineral content in the geographic area in
which the machine is located.

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.

The timer controls the drive motor, wash pump and the CH66, MD66, I66 prewash pump.
The timer is internal to the RCM. The PUMPS output indicator light shows the RCM Timer is
