22. Close the Inlet Sea Cock Valve. This is a safeguard for vessel installations.
23. If the freshwater flush is installed and activated, do not interrupt power. If the freshwater flush is
not installed or is not activated, turn off the electrical power source (circuit breaker) to the system.
This eliminates the chance of inadvertently starting the system. If the power source has been turned
off, the freshwater flush will not cycle every 7 days.
Pressure Changes
The system operating pressure (the pressure applied to the RO Membrane Element) varies with the
feed water temperature, the feed water salinity and the condition of the RO Membrane Element. The
system design specifications are based on feed water temperature of 77° F / 25° C and a feed water
salinity of 35,000 PPM-TDS (parts per million-total dissolved solids). Each RO Membrane Element
can vary +/- 15%, which will cause the final operating pressure to decrease or increase accordingly.
However, assuming the "perfect RO Membrane," at this temperature and salinity the system will operate
at the standard system pressure listed within the specifications at the beginning of this Owner's Manual.
If the feed water salinity increases or if the feed water temperature decreases, the system operating
pressure will increase. Inversely, if the feed water salinity decreases or if the feed water temperature
increases, the system operating pressure will decrease. Furthermore, if the RO Membrane Element
is new or old and fouled, the system operating pressure automatically decreases or increases
accordingly to overcome the RO Membrane Element condition.
Operating amperage and operating pressure will increase if:
1. The feed water temperature is lower than 77º F / 25º C.;
2. The feed water salinity is greater than 35,000 PPM TDS (3.5% Total Dissolved Solids);
3. The RO Membrane Element becomes fouled;
4. The RO Membrane Element is new and on the minus 15% side of the specifications.
Operating amperage and operating pressure will decrease if:
1. The feed water temperature is higher than 77º F/ 25º C.;
2. The feed water salinity is less than 35,000 PPM TDS (3.5% Total Dissolved Solids);
3. The RO Membrane Element is new and on the plus 15% side of the specifications.
By monitoring feed water salinity, temperature and resulting system operating pressure, it is possible
to measure and monitor the fouling of the RO Membrane Element over time and use. As the feed
water vane pump becomes worn from normal use, it will lose flow and the ability to build up pressure.
A reduction in product water production could be caused by insufficient pressure and/or flow from the
booster pump. Should the booster pump become worn resulting in reduced pressure and/or flow, it
may be returned to Horizon Reverse Osmosis for rebuild or replacement. Because of the specific
matching requirements of the wear parts and tight tolerance, it is not practical to repair in the field.
