20. 7610 002 64 22 Issued 07 26 2006 Revised N A 12 SECTION 2 INSTALLATION OPERATION INSTRUCTIONS DETERGENT CONTROL Detergent usage and water hardness are two factors that contribute greatly to how efficiently your dishmachine will operate Using detergent in the proper amount can become in time a source of substantial savings A qualified water treatment spe cialist can tell you what is needed for maximum efficiency from your detergent but you should still know some basics so you ll understand what they are talking about First you must understand that hard water greatly effects the performance of the dishmachine Water hardness is the amount of dissolved calcium and magnesium in the water supply The more dissolved solids in the water the greater the water hard ness Hard water works against detergent thereby causing the amount of detergent required for washing to increase As you use more detergent your costs for operating the dishmachine will increase and the results will decrease The solids in hard water also may build up as a scale on wash and rinse heaters decreasing their ability to heat water Water temperature is important in removing soil and sanitizing dishes If the water cannot get hot enough your results may not be satisfactory This is why Jackson recommends that if you have installed the machine in an area with hard water that you also install some type of water treatment equipment to help remove the dissolved solids
