Note: Procedures are the same for the SC-2 and SC-3 cleaners

Warning! The pressure relief valve on the Clark pump must be open for this procedure or membrane damage may result. Maximum pressure 50 psi.

A Spectra Cleaning Compound (SC-2 or SC-3) must be mixed with fresh water at a ratio of 1 con- tainer of compound to 3 gallons (12L) of unchlorinated water to have the proper solution. An average of two gallons (8L) of water is already present inside a 400 system . This water has to be figured into the mixture. A 400 system will use 1 container of compound. SC-2 and SC-3 are never mixed to- gether. Do not use them for storage pickling solution.

Cleaning Procedure:

•Step 1: Close the seacock. Flush the system twice. Use the “Auto Flush” button on the MPC-5000 display, once the first flush has been completed, press “Stop” to cancel the 5 day interval timer, then press “Auto Flush” again.

•Step 2: Remove the quick disconnect fitting from the brine discharge outlet of the Clark pump, and replace with a quick disconnect from your service kit, fitted to a hose, and lead the hose to a bucket.

•Step 3: Press “Auto Flush” again to fill the bucket with 1 gallon (4L) of fresh unchlorinated water. Press “Stop” when the bucket has reached the desired level.

•Step 4: Connect a hose, using the garden hose barb fitting from your service kit, to the ser- vice 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: Mix the cleaning chemical compound into the water in the bucket.

•Step 6: Make sure the pressure relief valve on the Clark pump is Open (unpressurized).

•Step 7: Use the “Run Manual” switch on the MPC control box to turn on the feed pump. Circulate the storage chemical in the system for approximately 25 minutes. Circulate the chemical in the system for approximately 25 minutes. Allow to soak for several hours or overnight if the solution is cold. Run the pump occasionally to agitate the solution. Set both switches to Auto when finished.

•Step 8: Turn off the control system (DC) power. Replace the brine over- board hose. Remove the Inlet Service hose and turn the Service valve to the Run position.

•Step 9: To avoid damaging the membranes, Follow the “New System Startup” In- structions to Purge the chemicals out of the System.

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.
