It is essential to supply the steam generator with water that will not form scale.
Even though the steam generator is engineered to minimize scale formation, scale
development depends on the hardness of your water and the number of hours per day
you operate the equipment.
Most water supplies are full of minerals which form scale. It is this scale which could
lead to an early component failure.
Your water utility can tell you about the minerals in your water. The water going to
the steam generator should have no more than 10 to 30 parts per million (ppm) total
dissolved solids (TDS) and should have a pH (acidity rating) of 7.0 or higher. Please
follow these simple precautions:
1. The best way to prevent scale is to use a water treatment system which has
been specifically designed for steamers and combination ovens. Do not rely on
unproven water treatment systems sold for scale prevention and removal. They
are not specifically designed to work with steamers and combination ovens.
2. A well-maintained water treatment system and a regular cartridge replacement
schedule is essential.
3. Using a water treatment system will provide longer steam generator/boiler life,
higher steam capacity, and reduce maintenance requirements.
4. If you notice a slowdown in steam production or an increase in deliming, have
the steamer checked for scale build-up. This could be an indication that the
water treatment cartridges need replacing. Heavy scale reduces the unitʼs ability
to boil water, and can even cause component failure.
MINIMIZE SCALE PROBLEMS BY USING AND MAINTAINING A SOFTENER AND BY
CLEANING (DELIMING) THE STEAMER REGULARLY.
On both the 3-pan and 5-pan, the dual water connections are side by side on the rear
of the unit. When seen from the back of the unit, the treated (softened) water intake is
on the right.
