minimum of 1 U.S. Gallons (3.8 Liters) per minute at minimum 25 PSI and maximum 60 PSI (minimum 172 kPa
and maximum 414 kPa).
• If the Minimum of 1 U.S. Gallons (3.8 Liters) per minute at minimum 25 PSI (minimum 172 kPa) 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 60 PSI (maximum 414 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.
System Storage
If the System is not equipped with the Automatic Fresh Water Flush option or it will not be operated for an extended
period of time (i.e., three months or longer), then you must perform a manual fresh water flush.
Fresh Water Flush
Automated Fresh Water Flush
If the Automated Freshwater Flush (FWF) Accessory is installed, after a 90-minute delay, the Seafari Quest is
flushed with freshwater automatically each time the system is stopped after operation. The Seafari Quest may also
be flushed with freshwater simply by pressing the FWF switch at the touch pad. Refer to the two diagrams in this
chapter, which illustrate the water flow when the Seafari Quest 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/Energy Transfer Device Return either from
the RO Membrane/Vessel Assembly Outlet (brine discharge end) or from the ETD (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 ETD 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.
