Membrane Cleaning Procedures
Spectra cleaning compound (SC-2 or SC-3) must be mixed with fresh water at a ratio of 1 container of
compound to 3 gallons (12L) of unchlorinated water. An average of two gallons (8L) of water is already
present inside a Ventura system, so this water must be figured into the mixture. A Ventura system re-
quires one container of compound per cleaning.
1. Turn the yellow service valve on the feed pump module to OFF (horizontal, see photo).
2. Push Auto Store to fresh water flush the system. Repeat, to flush the system twice.
3. Remove the cap on the service port on the feed pump module and install the inlet service hose
from the service kit. Remove the quick disconnect fitting from the brine discharge outlet of the
Clark Pump, and replace it with the quick disconnect brine discharge service hose. Lead both
hoses into a 5 gallon (20 liter) bucket.
4. Push the Auto Store button and run the feed pump until one gallon of fresh water runs into the
bucket from the brine discharge service hose. Stop the system.
5. Turn the yellow service valve to the SERVICE position.
6. Make sure that the pressure relief valve on the Clark Pump is open (un-pressurized).
7. Mix the cleaning chemical in the bucket. If possible, heat the solution to 120 deg. F (49 deg. C).
8. Start the system using the manual switch on the MPC control box. The intake service hose will
draw solution from the bucket and the brine discharge service hose will return it. Circulate the
solution through the system in this manner for 45 minutes.
9. Stop the pump. Replace the brine discharge overboard hose and run the pump until the bucket
is empty. Stop the pump and turn the yellow service valve back to the RUN position. Restart
the pump and run for 20 minutes to flush the chemicals out of the system (DO NOT CLOSE the
pressure relief valve!)
10.
Move the switch on the MPC Control Box to AUTO. The system may now be restarted, flushed,
or stored.
