2.0 PRE-INSTALLATION NOTES
2.1 PRECAUTIONS
Reverse Osmosis (RO) System storage prior to uncrating:
CAUTION
DO NOT store in direct sunlight.
DO NOT store above 103 degrees F (39 degrees C).
DO NOT freeze.
CAUTION
If the RO system has been shipped new with Reverse Osmosis Membrane Elements installed,
the System must be commissioned within 3 months. This is to avoid drying out or biological
fouling of the RO membranes.
2.2 RO SYSTEM LOCATION
The RO unit should be installed in a dry, sheltered location protected from direct weather.
Some type of drainage should be provided beneath the RO unit to allow standing water to
drain when performing maintenance or repair.
The following two diagrams that show the RO System located relative to the seawater level. The
first shows the RO System installation below water line and the second shows the RO System
installation above water line.
Figure 2.1 –RO Below Water Line

Figure 2.2: RO System Above Water Line
2.3 INSTALLING THE SYSTEM
Since every installation is unique, the mounting instructions are provided for guidance
only. It is recommended that you use your own discretion as to the exact method of
mounting and placement of any mounting bolts.
1) Mount the RO unit securely. Secure each skid in place using vibration isolators as
required. Follow the maintenance envelope provided in the General Arrangement
drawing.
CAUTION
All mounting surfaces must be flat to avoid warping of brackets and frames. Grind flat or
use of appropriate shims on uneven surfaces to ensure that mounting of the system
components does not cause bending or warping. Any damage caused by attaching the
system or its components to an uneven surface is attributed to improper installation, is
the liability of the installer, and is not covered by the Parker Hannifin warranty.
2) Make the following plumbing connections to the RO unit's piping interfaces provided on
the General Arrangement drawing.
CAUTION
Inlet and discharge interconnecting lines must be constructed of a NON-FERROUS
material. Examples of some suitable materials are PVC, copper-nickel, 316 stainless steel
pipe or a reinforced non-collapsing hose. Ferrous piping produces rust that will
irreversibly foul the membrane and void the RO unit warranty.
a) Connect the sea water supply to a clean seawater source using a flexible
connection to the unit.
