38) POTABLE WATER STORAGE TANK**
Storage tank may be any non pressurized container
suitable for storing Potable Water, i.e. existing water
storage tank on a boat or cistern for a home. This
container must not be pressurized.
39) AIR ENTRAINMENT TANK** (accumulator)
Some Fresh Water Pressure Systems rely only on the
Pressure Pump to deliver pressurized Fresh Water to
the boat or home piping. Other Fresh Water Pressure
Systems incorporate an Air Entrainment Tank. It is not
important to the System which configuration the boat
or home has. The only requirement to the System, for
Fresh Water Flushing, is that the Fresh Water Pressure
System in the boat or home must deliver to the System
during the Fresh Water Flush cycle a minimum of 4.5 U.S.
Gallons (17 Liters) Per Minute at minimum 25 PSI (173
kPa) If the Fresh Water Flush cycle is unable to perform
due to insufficient Fresh Water flow and pressure replace
the Pressure Pump with a pump capable of meeting the
minimum standards stated above.
40) AUTOMATIC FRESH WATER FLUSH
Includes a 2-Way Solenoid Valve, potable water Check
Valve, Carbon Filter, and feed water Check Valve that
allow automated flushing of the System with Fresh Water.
This process is automatic at each shut down of the
system and repeats automatically. Fresh Water Flushing
replaces the seawater in the system with less corrosive
fresh water, and this also reduces the biological growth
and subsequent decay that naturally occur if the feed
water (sea water) is not flushed from the system with
fresh water during disuse.
a)
Fresh Water 2-Way Solenoid Valve energizes to
allow fresh water to flush the System at shut down
and automatically every preset number of days.
In the de-energized position the valve isolates the
feed water from the fresh water.
b) Potable water Check Valve is another safe guard to
isolate the fresh water from the feed water.
c) Fresh Water Flush Carbon Filter removes chlorine,
if present, in the fresh water prior to flowing
through the R.O. Membrane Element.
d) Feed water Check Valve ensures that the fresh
water used to flush the system travels through
the system and prevents it from exiting the inlet
thru hull fitting.
Fresh Water Flush 2-Way Solenoid Valve is normally
closed and actuates to open during the fresh water flush
cycle to allow fresh water into the system.
Problems and Symptoms appearing and caused by the
Fresh Water Flush 2-Way Solenoid Valve:
a)
The Fresh Water Flush Cycle is off but fresh water
is passing through the Fresh Water Flush 2-Way
Solenoid Valve
The valve ports may be improperly allowing
by-pass.
Solution : Replace the valve.
b) The Fresh Water Flush Cycle is on but fresh water
does not pass through the Fresh Water Flush
2-Way Solenoid Valve
The valve ports may be improperly allowing
by-pass.
Solution : Replace the valve.
The valve’s solenoid may be electrically
non functional.
Solution
: Check for 12 VDC. If present, replace
the valve. If 12 VDC is not present troubleshoot
the electronics.
Fresh Water Flush Check Valve stops feed water from
entering the potable water line.
Problems and Symptoms appearing and caused by the
Fresh Water Flush 2-Way Solenoid Valve:
a)
The Fresh Water Flush Check Valve is allowing
feed water to mix with potable water.
Solution
: Replace the Fresh Water Flush
Check Valve.
Fresh Water Flush Charcoal Filter removes chlorine, if
present, in the fresh water prior to flowing through the
R.O. membrane element.
Problems and Symptoms appearing and caused by the
Fresh Water Flush Charcoal Filter:
a)
The Charcoal Filter is no longer removing the
chlorine from the Fresh Water.
As the Charcoal Filter becomes saturated it looses
its ability to remove chlorine from the Fresh Water.
Solution
: Replace the Charcoal Filter Element
every 3 months.
Fresh Water Flush Tee Connector and Check Valve stops
fresh water from exiting the Inlet Thru Hull Fitting and
routes the fresh water through the system during the
