Warning! Use only potable water antifreeze (Propylene Glycol). Do not use automotive antifreeze (Ethylene Glycol).

Propylene Glycol is an effective biocide and antifreeze only at concentrations above 25%. Commercially available products range from 25 to 60 percent. They are usually labeled with a temperature rating. “Minus 50” antifreeze is already diluted to 25%. “Minus 100” is a 60% solution. Purchase the strongest antifreeze available. Use enough to ensure that the system contains at least a 25% solution even after dilution with the residual water inside the water- maker.

Step 1: Flush the system for 12 minutes using the manual operation switch. Set the switch to “Service.” The water maker will begin to flush itself. To stop the flush Set the switch to “Run Auto”.

Step 2: Open pressure relief valve on the Clark pump.

Step 3: Pour the propylene glycol into a bucket. Follow the instructions on the con- tainer.

Step 4: Connect the hose, using the garden hose barb fitting from your service kit, to the service port of the boost pump module. Lead the hose into the bucket. Turn the service valve on the boost pump module 180°, so the intake is now coming from the bucket.

Step 5: Pump as much as possible of the water remaining inside the water maker overboard.

Set the switch on the pump module to “Service” to turn on the feed pump. Run the feed pump until you see antifreeze begin to appear in the brine overboard hose. Set the switch to “Run Auto” to stop the feed pump.

Step 6: Remove the quick disconnect fitting from the brine discharge outlet of the Clark pump, and replace with the quick disconnect hose from your service kit, and lead the hose to the bucket.

Step 7: Set the switch to “Service” to circulate the antifreeze for about ten minutes.

Switch to “Run Auto” to stop the pump.

Clean Up:

Remove the quick disconnect from the Clark pump brine discharge, and replace the original hose that leads to the thru-hull. You may at this point, if you choose to, pump the bucket dry by using the feed pump switch. Stop when the bucket is empty.

Turn the service valve 180° back to its original position, and remove the service hose.

Turn off the power to the system.

LEAVE THE PRESSURE RELIEF VALVE ON THE CLARK PUMP OPEN.

With the ability to produce up to 400 gallons of freshwater per day, the Newport 400 is ideal for extended cruising, offshore adventures, or as a backup water supply.

One of the standout features of the Newport 400 is its patented Spectra Reverse Osmosis technology. This advanced system harnesses the power of reverse osmosis to remove salt and impurities from seawater, ensuring the production of clean and safe drinking water. The Newport 400 operates with exceptional energy efficiency, requiring significantly less power compared to traditional watermakers. This is particularly beneficial for boats relying on limited energy sources like solar panels or generators.

The Newport 400 is engineered for ease of operation and maintenance with a user-friendly control panel. Operators can easily monitor key parameters such as water output, pressure, and system status. The intuitive interface makes it simple to adjust settings and troubleshoot potential issues. Additionally, the system is constructed from high-quality corrosion-resistant materials, ensuring durability and longevity in harsh marine environments.

An impressive characteristic of the Spectra Newport 400 is its ultra-quiet operation. This watermaker is designed to minimize noise, making it perfect for use in the close quarters of a yacht without disturbing the peace on board. The integration of advanced technologies further enhances its performance, including a sophisticated water pre-filtration system that reduces the risk of membrane fouling.

The Newport 400 is also designed with versatility in mind. It can be easily integrated into various onboard systems, allowing for simple installation and operation. Its compact size means it can fit into tight spaces on smaller vessels without sacrificing performance.

In summary, the Spectra Watermakers Newport 400 is a reliable, efficient, and quiet solution for generating freshwater in a marine environment. Its advanced reverse osmosis technology, ease of use, and robust construction make it an ideal choice for boaters seeking independence from shore-based water sources. Whether for leisurely cruising or serious ocean voyaging, the Newport 400 stands out as a top-tier watermaker for modern maritime adventures.
