CAUTION
Avoid connecting the inlet piping to any water line that services any other piece of
equipment. Air could be drawn through the RO unit causing damage to the RO unit's
pumps. Any air suction leaks coming into the system feed line may cause the system to
shut down due to low feed pressure. If possible, plumb the feed line at the bottom of the
Sea Chest. This ensures an uninterrupted supply of air free seawater.
b)
Connect the reject discharge (concentrate flow), to an unobstructed line using a
flexible connection. The reject should be discharged overboard above the
waterline.
CAUTION
The use of galvanized steel for product piping should be avoided as small amounts of rust may
form that can be drawn back into the RO when the system is off.
c)
Connect the product water discharge using a flexible connection to an unobstructed line
that is connected to the TOP of the product water storage tank. If the storage tank water
is chlorinated, a check valve or air gap should be installed in the product line as a
precaution to prevent chlorine damage of the RO membranes. The air gap is often
accomplished by teeing the product connection to a tank vent or tank fill line of suitable
size.
CAUTION
Exposing the membranes to chlorinated water may cause irreversible damage and will void the RO
unit warranty.
3)
Connect the following RO unit's electrical interfaces:
CAUTION
Strictly observe all applicable electrical codes and regulations governing the installation
and wiring of electrical equipment. Never connect the RO unit to a line that services
another electrical device. The RO unit should have its own dedicated power supply and
breaker.
WARNING
DISCONNECT ELECTRICAL POWER TO RO UNIT AND THE POWER SOURCE BEFORE
WORKING ON THE RO UNIT. FAILURE TO DO SO CAN CAUSE SERIOUS INJURY OR
DEATH TO PERSONNEL.
4)
Motor rotation. The Booster Pump and the High-Pressure Pump has proper markings to
determine rotation.
