INTRODUCTION
Thank you for purchasing an HRO Systems Reverse Osmosis Desalination System. Please read this
manual carefully before attempting installation or operation. A better understanding of the system
ensures optimum performance and longer service life from the system.
All HRO reverse osmosis desalination systems are designed and engineered to function as a complete
working unit. Generally speaking, the performance of each component within the unit is dependent on
the component prior to it and governs the performance of all components after it. Proper performance o
f
the system is thus dependent upon proper operation of every single component within the system.
The intent of this manual is to allow the operator to become familiar with each component within the
Horizon Seafari system. By understanding the function, importance, and normal operation of each
component within each subsystem of the unit, the operator can readily diagnose minor problems. Such
p
roblems, when they first develop, usually require minor
m
aintenance and are easily corrected.
However, left unattended, a problem in one component affects the rest of the system and leads to further
required repairs.

CAUTION: The Horizon Seafari Reverse Osmosis Desalination Systems are designed to be as electrically
efficient as possible. RPM supplied to and Pressure created by the High Pressure Pump govern the amount of
energy required by the High Pressure Pump’s Electric Motor. In order to maintain a sufficient flow of feed
water into the Reverse Osmosis Membrane Element, Horizon Seafari utilizes several different High Pressure
Pumps with different displacement characteristics. These different High Pressure Pumps, in turn, have
different power requirements.
As such, several different Electric Motors are used in the Horizon Seafari Systems. In order to maintain
maximum operational versatility HRO Seafari Systems utilize dual Cycle (Hz) Electric Motors capable of
operating from both 50 Hz and 60 Hz.
In a Boat application, use caution when switching from your auxiliary AC on board generator to shore power.
In many cases, due to insufficient wiring or long distances from the power source to the end of the dock, shore
power from a Marina may be insufficient to operate your Horizon Seafari System. Low voltage to the Horizon
Seafari System causes damage to the electric motor. Damage caused to the system due to low voltage is not
covered by Warranty.

SECTION “C”
INTRODUCTIONS

HROSystems Horizon Seafari “Section C” Introduction
C. INTRODUCTION
The Obstacle:
Osmosis is the naturally occurring
diffusion of two miscible (mixable)
solutions through a semipermeable
membrane in such a manner as to
equalize their concentration by
allowing a lessor concentration,
potable water, to naturally diffuse
through a semipermeable
membrane into a higher
concentration, sea or brackish
water.
Sea water or brackish water is a high
concentration solution. Potable
water is a low concentration
solution.
Therefore, sea water or brackish
water cannot naturally diffuse
through a semipermeable
membrane to provide potable, or
drinking water.
The HRO Solution:
A manmade process, Reverse
Osmosis, overcomes this natural
phenomenon. By forcing sea or
brackish water (under high pressure)
through a semipermeable
membrane, potable water can be
realized. Reverse Osmosis
Desalination Systems by
HROSystems make possible the once
impossible, potable water from
undrinkable water sources.
Low Pressure: Feed Water (Salt
Water or Brackish Water) enters the
system through an Inlet Valve and is
then filtered by a raw water Sea
Strainer. The pressure of the Feed
water is increased by the Booster
Pump and filtered several more times
through standard and optional
prefiltration units including Media
Filter, Plankton Filter, Prefilter and
Oil Water Separator.
High Pressure: The Stainless Steel
High Pressure Pump then increases
the filtered feed water to a high
pressure level and forces it into the
Reinforced Fiberglass Membrane
Vessel Assembly. The Back Pressure
Regulator controls and automatically
maintains the necessary high
pressure level in the membrane.
Concentrated brine enters the Brine
Water Flow Meter which allows
observation of the condition of the
High Pressure Pump. The Brine
Water is then discharged through the
Brine Discharge Connector and
diverted back to the feed source.
Product Water: The product
water flows out of the R.O.
Membrane and passes into a Salinity
Probe which adjusts automatically
for temperature changes and
registers,
electronically, the salt content of
the product water. Next, the
Product Flow Meter registers the
amount of potable water being
produced. The product water then
proceeds into the 3-Way Solenoid
Diversion Valve. Here, potable
water is diverted to the Charcoal
Filter where gasses or odors present
are absorbed and removed from the
product water. The final filtration
process occurs in the Ultraviolet
Sterilizer where 99.9% of all
microorganisms, including viruses
and bacteria, are destroyed.
