New System Start - Up and Testing
Avoid running the Ventura system if the vessel is in contaminated water. The system should be fully tested before
leaving port. If the location or weather prevents proper testing, refer to
Dry Testing with an Artificial Ocean on
page 28.
Every new system is shipped from the factory with nontoxic, food - grade propylene glycol. Propylene glycol,
Spectra Chemicals, or anything other than seawater or freshwater must be purged from the system with the
pressure relief valve open at least 1/2 turn. You can purge your system with seawater or with freshwater via the
system
’ s freshwater flush function. The system must be purged for a minimum of 60 minutes, or until at least 40
gallons of water have moved through the system.
***When purging SC - 1 from a pickled watermaker, system must be purged for a minimum of 20 minutes.
Propylene Glycol should be purged for minimum 60 minutes***
Warning! Damage may occur if the purge sequence is bypassed and the membrane is pressurized with
storage chemical in it.
1. First, check that:
•
Thru - hull inlet and the brine discharge valves are open.
•
All of your hose connections are tight.
•
The washer with the green tag under the pressure relief valve has been removed.
•
The pressure relief valve is open at least 1/2 turn.
•
The sampling valve is set to the sample position
•
The brine line is able to freely discharge
Open 1/2 Turn when
purging chemicals!
Remove Tag and Washer!
For a purge with seawater
• Move to an area free of contaminated water,
such as in a polluted harbor or canal.
To Sample To Tanks
For a purge using the freshwater flush
• The vessel ’ s pressurized water system
is on
2. Turn on feed pump via the manual toggle switch and check to make sure water is coming out of
the brine discharge (thru - hull above water).
3. Run the system without pressure for 60 minutes to purge the storage chemicals. The pressure
gauge should read less than 35 PSI. If purging with freshwater, the sampling tube may discharge wa-
ter.
4. Close the pressure relief valve. The pressure should rise to 60 - 80 PSI (4.2 - 5.7bar) on a Ventura 150
and 80 - 90 PSI (5.5 - 6.5 bar) on a 200T. Water should begin to flow out of the sampling tube. If the
ship is located in brackish or fresh water, the pressure will be lower.
Depending on storage and environmental conditions the system may need to have additional purging
time. If the product water does not taste pure or sample at below 500 ppm, purge or run the system
for up to 6 additional hours.
