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: Connect the brine discharge service hose to the Service Port on the Brine Discharge
Service Module , turn the yellow handled service valve to the Service position , and lead the
hose to a bucket.

Step 3: Press “Auto Flush” again to fill the bucket with 2 gallons (8L) of fresh
unchlorinated water. Press “Stop” when the bucket has reached the desired level.

Step 4: Connect the intake service hose, using the garden hose barb fitting from your service
kit, to the
service port of the Intake Service Module . Lead the hose into the same bucket as
the brine discharge service hose. Turn the service valve on the Intake Service Module 180°,
so the intake is now coming from the bucket.

Step 5: Mix the cleaning chemical compound into the water in the bucket. Note that not all
of the chemical will dissolve completely into solution. This is acceptable and will not harm
the system.

Step 6: OPEN THE PRESSURE RELIEF VALVE ON THE SPECTRA-PEARSON
PUMP.

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. Allow to soak
for several hours or overnight if the solution is cold. Run the pump occasionally to agitate
the solution.
Set the toggle switch to ‘Run Auto’
when finished.

Step 8:
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”
Instructions
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
container of compound to 3 gallons (12L) of unchlorinated water to have the proper solution. An
average of four gallons (8L) of water is already present inside a Farallon system . This water has to
be figured into the mixture. A Farallon system will use 2 containers 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 Spectra-Pearson 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
