IMPORTANT:
If your water is out of range, consult a water quality expert.
In addition to the previous requirements, observe the following requirements and recommendations:
•
Do not treat the water with softeners. Softeners can produce foam, which affects the operation of the

•
Do not use well water, industrial water, water from cooling circuits, or water contaminated by any
chemicals or bacteria.
•
Do not add potential irritants to the water, such as disinfectants or anti-corrosive compounds.
•
