Maintenance
USING YOUR RINSE TIMER
Each unit comes with a rinse timer. The purpose of rinsing is to flush out seawater that
may contain microscopic sea life and may cause a foul odor if left in the membrane over
time. Rinsing is recommended for the system when it is not in regular use.
AUTOMATIC RINSE
To rinse your system, connect pressurized water from your
house pump to the input (1/2" tubing) and set the timer for AUTOMATIC RINSE:
once every 5 days, for approximately 30 minutes or 2 gallons.
NOTE:
All Seawater Pro units include automatic check valves
therefore the rinse process is fully automated once you set
the timer.
MANUAL RINSE
Using the manual override knob, rotate to the “RESET” position and wait for 2 seconds.
Rotate the manual override knob to the desired setting, depending on your house's water
pressure. It takes approximately 2-3 gallons (8-10 Liters) to displace all the salt water with
freshwater.
Estimate about 30 minutes or measure your overboard water
to determine the exact interval.
NOTE:
Rinsing the unit after every use will extend the life of all
components.

Maintenance
REPLACING PRE-FILTERS
There is 1 pre-filter. The pre-filter requires a 5-micron filter. It measures
2.5 inches in diameter by 10 inches in length. The filter needs to be
replaced as needed or every 6 months. If you notice a drop on the low
pressure gauge then it is time to clean or replace the filter. Also, if you
can see algae growing on the filter, then it is time to clean or replace
the filter. Low
Pressure
Gauge
Carbon Filters
The system comes equipped with a carbon filter. The carbon filter is
never exposed to seawater; this filter is only in use when rinsing. The
carbon filter ensures that chemicals such as chlorine and fluoride do
not enter the membranes from a dock source or a chlorinated tap. We
recommend that you replace this filter once every nine months.
Note:
Chlorine or chemicals that are similar will damage the integrity of the
membranes.
You can purchase filters directly from www.SeaWaterPro.com.

Maintenance
REPLACING PUMP OIL
1. To drain the oil, remove the drain plug at the bottom of the pump.
2. The first oil change is due after 50 hours of use. After that, it is recommended
.....to replace the oil once a year or every 300 hours.
3. You may use any engine oil you happen to have available:
....10W30, 5W40, synthetic, or non-synthetic.
4. Fill according to the dipstick or use a sight glass.

WINTERIZATION PROCESS:
Seawater Pro, LLC. is a company that specializes in the production of high-quality
watermakers. In order to ensure that our products maintain their optimal performance and
longevity, the company recommends implementing freeze protection for the preservation
of their watermakers during the winter months.
Freeze protection involves the use of special additives, such as 100% food-grade
propylene glycol and water [1 propylene glycol:2 water gallon ratio], to help prevent water
from freezing inside the watermaker's components and causing damage. When water
freezes, it expands, and this can cause internal components to crack or break, leading to
costly repairs. By implementing freeze protection, Seawater Pro, LLC. ensures that their
watermakers are protected from these potentially costly damages.
To effectively implement freeze protection, it is important to follow the proper
winterization procedures. This involves draining all water from the system, adding the
appropriate amount of propylene glycol and water to the components, and running the
system on boost pump pressure ONLY to ensure that the freeze-protection solution is
evenly distributed throughout the system. DO NOT PRESSURIZE THE SYSTEM! By doing
this, the watermaker is protected from freezing temperatures and can be easily restarted
in the spring.
In addition to freeze protection, Seawater Pro, LLC. recommends regular maintenance and
servicing of their watermakers to ensure optimal performance. This includes regular filter
changes, cleaning of the system, and inspection of the components for any signs of wear
or damage.

100% Food-Grade Propylene Glycol
Propylene glycol is an odorless chemical compound that is used as an anti-freeze solution in
various industries. Unlike its cousin, ethylene glycol, propylene glycol is non-toxic and safe for
human consumption. It has a low freezing point of -60°C, which makes it an ideal coolant for
extreme cold temperatures.
Seawater Pro, LLC, a Florida-based company, manufactures 100% propylene glycol-based
products that are used in marine desalination systems. Seawater Pro’s propylene glycol is
specially manufactured with a light blue colored tint. Our anti-freeze solutions are designed to
protect against freezing temperatures and corrosion, making them a popular choice for boat
owners. Seawater Pro's anti-freeze solutions are made with pure propylene glycol, which
provides maximum protection against freezing. Products are also biodegradable and
environmentally friendly, making them a preferred choice for those who are looking for eco-
friendly anti-freeze solutions that won't harm marine life or the environment.
100% food-grade propylene glycol is an excellent anti-freeze solution that is safe, effective, and
environmentally friendly. Companies like Seawater Pro, LLC. are dedicated to producing high-
quality products that meet the needs of their customers. As a boat owner or watermaker user,
understanding that propylene glycol-based anti-freeze solutions can help protect your
equipment from the damaging effects of freezing temperatures is imperative.
FREEZE PROTECTION: WARNING
There is a high probability of damaging your watermaker by exposing it to severe cold or icy
conditions. The following procedure will protect your watermaker against freeze damage.
DO NOT USE ETHYLENE GLYCOL (FOUND IN AUTOMOTIVE ANTIFREEZE PRODUCTS) FOR
FREEZE-PROTECTING YOUR WATERMAKER. ETHYLENE GLYCOL IS A TOXIC SUBSTANCE AND
MUST NOT BE INGESTED OR COME INTO CONTACT WITH YOUR SYSTEM.
USE ONLY FOOD-GRADE NON-TOXIC PROPYLENE GLYCOL. DO NOT USE PROPYLENE
GLYCOL BLENDED WITH SUPPLEMENTARY ADDITIVES.

Freeze Protection for Watermakers: Winterization Tips from Seawater Pro, LLC
One of the biggest risks to a watermaker during the winter months is freeze damage. Water left inside of
the system can freeze, expand, and cause irreversible damage to delicate components. To ensure your
watermaker stays in good condition throughout the winter, it’s important to take steps to protect it from
freezing temperatures.
Seawater Pro, LLC is a leading manufacturer of watermakers for boats and adventure lovers. Their team
of experts has provided some tips and recommendations for winterizing your watermaker to protect it
from freeze damage.
1. Drain the System
Before winterizing your watermaker, it’s crucial to ensure that all water is drained from the system. This
means opening all valves and disconnecting any water hoses. Use compressed air to blow out any
remaining water from the system. Be sure to open all faucets and drains to ensure that all water has
been removed.
2. Use 100% Food-Grade Propylene Glycol Anti-Freeze
Using 100% food-grade propylene glycol as an anti-freeze is an effective way to ensure that your
watermaker is protected throughout the winter months. It is a non-toxic, marine-specific anti-freeze. Use
a 1 propylene glycol: 2 water gallon ratio in a bucket, mixed thoroughly, with boost pump pressure ONLY
to circulate the solution throughout the system. Then cap off all inlets and outlets to prevent drying out
the membranes.
3. Remove Pre-Filters
It’s important to remove all pre-filters from the watermaker before winterizing it. This will prevent the
filters from becoming damaged due to freezing temperatures. Be sure to store the filters in a dry, warm
location to prevent damage.
4. Keep the System Dry
After all water has been drained from the system, it’s important to keep the system dry to prevent any
moisture buildup. Use a dry cloth to wipe down all components, and ensure that the system is
completely dry before storing it for the winter.
By following these simple steps, you can help protect your watermaker from freeze damage, and rest
assured that your Seawater Pro watermaker will remain in excellent condition throughout the winter
months. Seawater Pro, LLC is committed to helping its customers keep their watermakers in top
condition all year round.

After Winterizing: Tips from Seawater Pro, LLC
After successfully winterizing your watermaker using Seawater Pro, LLC products, there are a few
important steps you should take to ensure that your system is ready to return to operation.
1. Check all Connections
Inspect all hose and pipe connections to make sure they are tight and secure. Reconnect high-
pressure hose from pump to membranes.
2. Ensure Pre-filters are Reinstalled
Reinstall the pre-filters once the system is ready to be operated again.
3. Lubricate Moving Parts
Apply a light coat of lubricant to any moving parts, such as the pump or motors. This will ensure the
system runs smoothly when it is reactivated.
4. Pre-Assembly
When ready to use the system again, use boost pump pressure to run the system’s (depressurized)
brine water overboard for 30 minutes before making product water. Once the brine has been run
overboard for 30 minutes, connect the freshwater product hose from the system to the tank.
5. Boost Pump Assembly
