CONGRATULATIONS
Your Sea Xchange XTCII-Series Reverse Osmosis System is a durable piece of
equipment that, with proper care, will last for many years. This User's Manual outlines
installation, operation, maintenance, and troubleshooting details vital to the sustained
performance of your system.
If your system is altered at the site of operation or if the feed water conditions change,
please contact your local dealer or distributor to determine the proper recovery for your
application.
NOTE: PRIOR TO OPERATING OR SERVICING THE REVERSE OSMOSIS SYSTEM,
THIS USER'S MANUAL MUST BE READ AND FULLY UNDERSTOOD. KEEP THIS AND
OTHER ASSOCIATED INFORMATION FOR FUTURE REFERENCE AND FOR NEW
OPERATORS OR QUALIFIED PERSONNEL NEAR THE SYSTEM.
SAFETY

PRINCIPLES OF REVERSE OSMOSIS
REVERSE OSMOSIS
How Fresh Water Is Produced
Reverse Osmosis or “RO” is a process where freshwater water is produced by pumping
saltwater through a semi-permeable membrane.
Osmosis
Osmosis is a naturally occurring process where a weak solution will cross a semipermeable
membrane to mix with a highly concentrated solution. For example, a freshwater solution will
naturally want to mix with a saltwater solution.
Reverse Osmosis
To reverse this process work is put into the system using a pump. The pump causes pressure to
build up on the saltwater side of the membrane. This pressure forces water across the semi-
permeable membrane. The membrane is designed to allow the water molecules to pass while
preventing the salt and other solids from doing so. Fresh water is collected on the other side of
the membrane as a result.

Vessel hull number-
First step to commissioning a new system is to look over the install to be sure everything is installed correct. This check-
list must be gone through prior to powering up the system.
Have all plumbing connections have been made, and secured?
Have all plumbing lines been run to the correct locations?
Is the boost pump installed below the water line?
Has wire reinforced hose been used on the suction side of the boost pump?
Is raw water intake open?
Is the overboard open and free of obstructions?
Is the system voltage, hertz, and phase correct?
Is the circuit breaker sized properly with sufficient wire gauge?
Is the power cable connected to the power inlet terminals of the system?
Now power up the system,
Are all displays on and functional?
At this time follow the start-up procedure in the manual and operate the system for an hour at its rated capacity, then
record the following data.

ELECTRICAL REQUIREMENTS
ELECTRICAL The XTCII Series are available in 1Φ (phase).
230 volts at 14.9 amps (including booster pump)
50/60 Hertz available in the 230-volt unit
NOTE: IT’S RECOMMENDED THAT A QUALIFIED ELECTRICIAN WIRE YOUR SYSTEM IN
ACCORDANCE WITH ALL APPLICABLE CODES, RULES, AND REGULATIONS.
WARNING: TO REDUCE THE RISK OF ELECTRICAL SHOCK, THE INCOMING
POWER SUPPLY MUST INCLUDE A PROTECTIVE GROUND.
PLUMBING AND PIPING CONNECTIONS
PLUMBING
The membranes and high-pressure pumps used on XTCII-Series Reverse Osmosis Systems re-
quire a continuous flow of water with a maximum temperature not to exceed 113°F. Please see
Complete Install Guide and the connection drawings below.
CAUTION: ANY RESTRICTIONS OR BLOCKAGE IN THE CONCENTRATE LINE CAN
CAUSE BACKPRESSURE, WHICH WILL INCREASE THE SYSTEM’S OPERATING
PRESSURE. THIS CAN RESULT IN DAMAGE TO THE SYSTEM’S MEMBRANES AND
COMPONENTS.
TUBE CUTTING AND INSTALLATION PROCEDURE
Cut the tube square and remove burrs and sharp
edges. Ensure the outside diameter is free of score
marks. For soft or thin walled tube, we recommend
the use of a tube insert.
Push the tube into the fitting, to the tube stop.
To disconnect, ensure the system is depressurized,
push the collet square against the fitting. With the
collet held in this position the tube can be removed.

STORAGE OR WINTERIZATION OF UNIT
Option 1: Storage with Fresh Water Flush
When a system will not be used for a significant period of time (i.e. 3 months – 1
year), the best practice for storage of the system is to allow the automatic fresh
water flush to operate by leaving the power to the system on and ensuring that the
vessels fresh water system is ON and pressurized. Normal replacement of fresh
water flush filter is still required every 4 months.
Option 2: Storage without Fresh Water Flush:
If the vessel will not be able to allow for fresh water flushing over the duration of
the storage period, the membrane vessels must have static water replaced with
membrane storage chemical solution. Membrane storage chemical part # is
252404263.
Option 3: Winterization
Option 3a: Winterization with membrane rack removal - The best practice for
winterization is to remove membrane rack and store with membrane storage
chemical in heated storage climate. The remainder of the system should be stored
with propylene glycol from sea cock to overboard to prevent freeze damage
(propylene glycol can be purchased at most hardware or automotive retailers).
Option 3b: Winterization without membrane rack removal - If the system is
going to be exposed to freezing or near freezing temperature while being stored
and the membrane rack cannot be removed and stored in a heated climate, the
following should be done. A 50% solution of storage chemical and 50% propylene
glycol should be run through the entire system from sea cock to overboard and
then valve off both sea cock and overboard. Membrane storage chemical part # is
252404263.
NOTE: PROPYLENE GLYCOL CAN BE PURCHASED AT MOST HARDWARE OR
AUTOMOTIVE RETAILERS
WARNING: DO NOT USE ETHYLENE GLYCOL, ONLY NON-TOXIC
PROPYLENE GLYCOL SHOULD BE USED.
Re-commissioning of System after Storage or Winterization
After storage or winterization, the system must be completely voided of all storage
chemical and or propylene glycol. To do this, follow the new system startup guide
on page 28.

SEA WATER PLUMBING CONNECTIONS
1. Locate a dedicated sea cock to be used for booster pump supply. Sea cock should be a
minimum of 3/4” with a speed scoop to prevent a Venturi effect while vessel is underway.
2. Install a sea strainer with at least a 50-mesh rating after sea cock.
3. Install supplied booster pump below water line.
Note - Booster pump outlet must remain the highest point of pump and cannot be rotated 90°
4. Run reinforced suction hose from sea cock to sea strainer to booster pump in an upward flow
manner to prevent air traps.
5.
6. Use supplied white 3/4” flexible hose from discharge of booster pump to Pre-Filter Inlet
connection on Sea Xchange Sediment filter assembly located on left side of system. Filter
assembly may be remote mounted if desired.

PRE-FILTRATION
XTCII-Series systems are supplied with a 5-
micron sediment filter. Change when there is a
noticeable loss of outlet pressure. Ask your local
dealer or distributor about Pre-Filtration
systems, if required.
NOTE: THE SYSTEM MUST BE OPERATED IN
ACCORDANCE TO FEED WATER SPECIFICATIONS.
7. Double clamp all sea water hose connections to prevent potential leaks.
8. Locate connection labeled “Overboard” on lower left side of system. Run supplied white 1/2”
tube to a dedicated overboard connection.
Warning - Sea water overboard must never
be closed or obstructed while system is
operational. Closing or obstructing the
overboard flow on system may cause
permanent damage to system.

PRODUCT TO TANK CONNECTION
9. Locate the fitting labeled Product to Tank on left side of system. Connect supplied white 3/8”
tubing from system to the inlet of the ships freshwater tank. Be sure that there are no kinks in hose
run and avoid 90’s where possible to prevent restricted flow.
Warning - Ships freshwater tank must be vented properly to avoid back pressure on
system. Failure to do so may cause permanent damage to system and/or to not
function properly.
Warning - Product to tank must never be closed or obstructed while system is
operational. Closing or obstructing the product flow on system may cause permanent
damage to system and/or to not function properly.

FRESH WATER FLUSH CONNECTION
1. Locate filter assembly labeled Fresh Water Flush and connect the inlet of fresh water flush
solenoid to the ships pressurized freshwater system.
Note - a shut off valve is recommended to be installed on supply line to fresh flush assembly for
service.

ELECTRICAL CONNECTIONS
1. Connect main power supply to main power terminal blocks, connect power to booster pump from
contactor as shown below. Ground main power supply and booster pump to grounding bus bar.
Reference DWG SX0034.
• The XTCII-Series systems pump, and motor are available in 230 Volt, 50/60 Hertz, 1 Phase
• Ensure that the electrical circuit supplying the system is compatible with the requirements of
the specific XTCII model you are installing.
NOTE: IT’S RECOMMENDED THAT A QUALIFIED ELECTRICIAN WIRE YOUR SYSTEM IN
ACCORDANCE WITH ABYC REQUIREMENTS.
WARNING: TO REDUCE THE RISK OF ELECTRICAL SHOCK, THE INCOMING
POWER SUPPLY MUST INCLUDE A PROTECTIVE GROUND.
