minimum of 1 U.S. Gallons (3.8 Liters) per minute at minimum 30 PSI and maximum 75 PSI (minimum 2 Bar
and maximum 5 Bar).

If the Minimum of 1 U.S. Gallons (3.8 Liters) per minute at minimum 30 PSI (minimum 2 Bar) is not achieved,
then the System may not fully flush the System with enough fresh water to displace the Feed Water (i.e., sea
water).

If the Maximum 75 PSI (maximum 517 kPa) is exceeded, then the System will shut down and revert to a fault
mode due to excess pressure. In this event, the Owner or Installer must install a Pressure Reduction Valve from
the ship's Pressurized Fresh Water Line prior to the inlet of the System Fresh Water Flush Charcoal Filter
Inlet.
Automated Fresh Water Flush
If the Automated Freshwater Flush (FWF) Accessory is installed, after a 2-minute delay, the Ultra Whisper is
flushed with freshwater automatically each time the system is stopped after operation. The Ultra Whisper may also
be flushed with freshwater simply by pressing the FWF for 5 seconds LCD controller. Refer to the two diagrams in
this chapter, which illustrate the water flow when the Ultra Whisper is performing an Automated Freshwater
Flush, if the included Freshwater Flush Accessory is installed.
Manual Fresh Water Flush
If the Automated Freshwater Flush Accessory is not installed, or if a manual freshwater flush is preferred, when
the instructions within this chapter state “configure for once
-
through rinse” to rinse the system with freshwater for
short-term non-use in non-freezing temperatures, proceed as follows.
1. Configure the suction line for a once-through process.
a) Close the Sea Cock Valve.
b) If the Optional Rinse/Clean Inlet Valve is not installed, disconnect the hose from the outlet line of the Sea
Strainer, and place it in the Rinse/Clean Solution Container or bucket.
c) If the Optional Rinse/Clean Inlet Valve is installed, position it to draw water from the Rinse/Clean
Container.
2. Configure the brine discharge line for a once-through process.
a) Connect the brine discharge line from the system to the thru-hull overboard discharge fitting. This is the
normal connection for normal operation.
b) If the system is equipped with an Optional Discharge Rinse/Clean Outlet Valve, position this valve to discharge
through the Brine Discharge Connector. This is the normal connection for normal operation.
Once-Through Depressurized Rinse
When the instructions within this chapter state “configure for once
-
through depressurized rinse” used for once
-through
flushing of storage chemical, winterizing chemical or rinse between RO Membrane cleaning, proceed as follows.
Refer to the two diagrams illustrated in this chapter.
1. In order to relieve pressure during the once-through winterizing rinse process, the Pressure Relief Tube Kit
must be installed.
a) Disconnect only one end of the High-Pressure Hose MVA Outlet/R.O. Boost Return either from the RO
Membrane/Vessel Assembly Outlet (brine discharge end) or from the R.O. BOOST (whichever is easier to
access).
b) Connect the Product Relief Tube Kit to the loose end of the High-Pressure Hose and to the exposed fitting
on the RO Membrane/Vessel Assembly Outlet or the R.O. BOOST fitting (whichever fitting the High-
Pressure Hose was disconnected from).
c) Route the 3-inch O.D. Tube from the Pressure Relief Tube Kit into the Rinse/Clean Solution Container or
bucket.
2. Configure the suction line for a once-through process.
a) Close the Sea Cock Valve.
