to maintain the normal product water production. The Ultra Whisper System self-adjusts by decreasing the operating
pressure to compensate for higher-than-normal feed water temperature. Product water quality will decrease, or
increase in salinity, as the operating pressure is decreased to compensate for the higher-than-normal feed water
temperature.
Low Product Water Quality (increase of salt content in the product water)
Mismatching of system components can cause lower-than-normal operating pressure resulting in low-quality
product water. A worn or broken product water O-ring at the end plug inside the high-pressure vessel will allow
feed water to bypass into the product water. The resulting mixture of product water and feed water will be of low
quality, or high in salinity. This will also show up as lower-than-normal membrane pressure at the control menu
LCD screen.
A crack in the end plug between the feed water port and product water port or a rough surface at the product water
O-ring will also allow feed water to bypass into the product water. The resulting mixture of product water and feed
water will be of low quality, or high in salinity. This will also show up as lower-than-normal membrane pressure at
the control menu LCD screen.
Higher-than-normal feed water temperature causes the RO membrane to require less operating pressure in order
to maintain the normal product water production. The Ultra Whisper System self-adjusts by decreasing the operating
pressure to compensate for higher-than-normal feed water temperature. Product water quality will decrease, or
increase in salinity, as the operating pressure is decreased to compensate for the higher-than-normal feed water
temperature.
A fouled RO Membrane Element will produce poor-quality product water since the RO Membrane Element allows
a constant passage of dissolved solids, salt and other minerals. The water molecules passing through the RO
Membrane Element dilute the constant amount of dissolved solids. Therefore, the greater the amount of water
passage, the lower the concentration, or lower percentage, of dissolved solids. As the RO Membrane Element
becomes fouled, less water passes through it to dilute the constant dissolved solids' passage. This results in
poor-quality product water. The Ultra Whisper System self-adjusts the operating pressure to overcome the fouling.
Eventually the High-Pressure Transducer will signal the system to shut off due to excessive operating pressure
above 925 PSI.
Product Water Tank has Foul Smell
If there is a Sulfurous odor (rotten egg smell) in the product tank, check for the following:
1. Dirty Post-Filtration Element.
Post-Filtration Elements has biological matter that has grown on them and now decaying. When this biological
matter decomposes, sulfur gas is released as a byproduct.
Check and replace as necessary Pre-filtration and Post Filtration Elements.
2. Charcoal Filter Element requires replacement.
Change the Charcoal Filter Element every 3 months.
3. Product Tank is dirty or has biological growth in it.
Clean and Chlorinate product tank.
