DETERGENT CONTROL:
Detergent usage and water hardness are two factors that contribute greatly to how efficiently your dish
machine will operate. Using detergent in the proper amount can become, in time, a source of substantial sav-
ings. A qualified water treatment specialist 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 dish machine. 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 hardness. 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 dish machine 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 from the water be-
fore it gets to the dish machine.
Second, hard water may have you adding drying agents to your operating cycle to prevent spotting,
when the real problem is deposited solids on your ware. As the water evaporates off of the ware, the solids
will be left behind to form the spotting and no amount of drying agent will prevent this. Again, using treated
water will undoubtedly reduce the occurrences of this problem.
Third, treated water may not be suitable for use in other areas of your operation. For instance, coffee
made with soft water may have an acid or bitter flavor. It may only be feasible to install a small treatment
unit for the water going into the dish machine itself. Discuss this option with your qualified water treatment
specialist.
Even after the water hardness problems have been solved, there still must be proper training of dish
machine operators in how much detergent is to be used per cycle. Talk with your water treatment specialist
and detergent vendor and come up with a complete training program for operators. Using too much deter-
gent has as detrimental effects as using too little. The proper amount of detergent must be used for job. It is
important to remember that certain menu items may require extra detergent by their nature and personnel
need to be made aware of this. Experience in using the dish machine under a variety of conditions, along
with good training in the operation of the machine, can go a long way in ensuring your dish machine oper-
ates as efficiently as possible.
Certain dish machine models require that chemicals be provided for proper operation and sanitization.
Some models even require the installation of third-party chemical feeders to introduce those chemicals to
the machine. Jackson does not recommend or endorse any brand name of chemicals or chemical dispensing
equipment. Contact your local chemical distributor for questions concerning these subjects.
