Description of the machine Description of the machine The G 7783 CD is a front-loading automatic machine for the efficient washing - neutralising - rinsing - final rinsing of laboratory glassware. It can be operated on normal water supply. There are "AD" (aqua destillata) programmes with final rinses using purified water (distilled, R.O., or de-ionised). On completion of the automatic programme sequence, laboratory glassware is cleaned to the standard required for analysis.
Setting the water softener Setting the water softener To avoid the build-up of calcium deposits on glassware and in the machine the water needs to be softened, where the supply hardness exceeds 107 ppm, (6°d). To ensure a steady supply of soft water the water softener unit must always be: 1. correctly set 2. reactivated with "dishwasher" salt as soon as the k indicator light comes on. The water softener must be set to correspond with the water hardness the first time the machine is used.
Setting the water softener Setting the water softener If the water hardness in your area is permanently below 107 ppm (6°d): Select setting "0". The control light k will not come on and the water softener does not need to be regenerated. Reactivating the water softener, see page 29.
