Rheem 701 Owner's Manual And Installation Instructions page 17

Operating the Boiling Water Unit Tap
The 702 and 703 Series have a push - pull tap assembly. Water flows from the tap
directly below the lever when the lever is operated.
The 701 Series has a push - pull lever located in the front panel of the unit. When
operated, boiling water flows from the spout on the underside of the unit.
Water Supplies
Your boiling water unit is manufactured to suit the water conditions of most
Australian and New Zealand metropolitan water supplies. However, there are some
known water supplies which can have detrimental effects on the boiling water unit
and its operation and/or life expectancy. If you are unsure of your water quality, you
can obtain information from your local water supply authority. This boiling water unit
should only be connected to a water supply which complies with these guidelines for
the Rheem warranty to apply.
Chloride and PH
In a high chloride water supply, the water can corrode stainless steel parts and
cause them to fail. Where the chloride level exceeds 250 mg/L the Rheem warranty
does not apply to the boiling water unit. The pH is used as a measure of the water‟s
alkalinity and acidity. In an acidic water supply, the water can attack metal parts and
cause them to fail. Where the pH is less than 6.5 or greater then 7.5, the Rheem
warranty does not apply to the boiling water unit..
Saturation Index
The saturation index is used as a measure of the water‟s corrosive or scaling
properties. In a corrosive water supply, the water can attack copper parts and cause
them to fail. Where the saturation index is less than –1.0, the water is corrosive and
the Rheem warranty does not apply. In a scaling water supply, calcium carbonate is
deposited out of the water onto any hot metallic surface. Where the saturation index
exceeds +0.80, the Rheem warranty does not apply to the storage vessel unless a
water softening device is installed.
WARNING
Boiling water units not installed in accordance with the above advice will not be
covered by the Rheem warranty.
