Spectra Watermakers Newport 400 owner manual Cleaning Procedure

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.
