Sea Recovery Ultra Whisper Rev. A
a. LOW PRESSURE FAULT:
The Low Pressure Switch [10] is a Normally Open Switch that closes at 40 PSI or greater pressure. The
Low Pressure Switch must receive minimum 40 PSI line pressure in order for it to "close" and maintain
operation of the System. The Low Pressure Switch monitors the Feed Water Line Pressure from the outlet
of the Feed Pump [6] and signals the Electronic Controller if there is a low pressure condition in the Feed
Line prior to or at the Feed Pump [6].
When the line pressure at the Feed Pump [6] Inlet experiences an abnormal vacuum, or the Feed Pump [6]
is unable to develop an Outlet Pressure of more than 40 PSI into the Prefiltration components, the
"High/Low Pressure" lamp illuminates intermittently, blinks. If the condition does not correct itself, or is
not corrected by the operator, the system automatically shuts down after 20 seconds and the "High/Low
Pressure" lamp illuminates, steady. Refer to the Trouble Shooting Section of this Manual.
b. HIGH PRESSURE FAULT:
The High Pressure Switch [11] stops the system if the pressure at the Feed Pump Outlet exceeds 190 PSI.
This protects the Prefiltration components from excessive pressure.
The High Pressure Switch is a Normally Closed Switch and will Open to immediately shut the System off
at 190 PSI. Refer to the Trouble Shooting Section of this Manual.
16. With no abnormalities, immediately after starting the Ultra Whisper System pressure will automatically increase
to normal operating range. The ETD [17] will increase pressure to a point at which the System produces the
specified amount of Product Water. The table below lists approximate expected pressures that a new system
should develop when operating in typical sea water of 35,000 PPM TDS at 77° F / 25° C.
PRODUCTION, OPERATING PRESSURE, AND OPERATING POWER CONSUMPTION:
The Fresh Water Production (Product Water) of the Sea Recovery Ultra Whisper is a constant percentage of
the Feed Water Flow, regardless of feed water temperature, salinity, or the condition of the membrane.
The Ultra Whisper System does not require manual pressure adjustment. The System automatically adjusts
operating pressure to produce a specific and pre set Product Water flow.
The table below illustrates the amount of Feed Water and the recovered amount of Product Water for each
System:
