Cleaning Procedure:
•
Step 1: 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 5 gallon bucket.
•
Step 3: Press “Auto Flush” again to fill the bucket with 1 gallon (4L) of fresh unchlori-
nated 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 fresh water flush module. Lead the hose into the bucket. Turn the service
valve on the fresh water flush 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 “ Manual” switch on the MPC control box to turn on the feed pump. Cir-
culate the storage chemical in the system for approximately 25 minutes. Turn off the
switch when finished. Allow to soak for several hours or overnight if the solution is cold,
running the pump occasionally to agitate the solution. Set the switch to Auto when fin-
ished.
•
Step 8: Turn off the control system (DC) power to reset the MPC-5000 controls. Replace
the brine overboard 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” instruc-
tions to purge the chemicals out of the system.
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 aver-
age of two gallons (8L) of water is already present inside a 300 system. This water has to be figured
into the mixture. A 300 system will use 1 container of compound. SC-2 and SC-3 are never mixed
together. Do not use them for storage pickling solution.
Warning! The pressure relief valve on the Clark pump must be open for this procedure
or membrane damage may result. Maximum pressure 50 psi.
NOTE: Procedures are the same for the SC-2 and SC-3 cleaners
