Storage & Winterizing
Warning! Use only potable water antifreeze (Propylene Glycol).
Do not use automotive antifreeze (Ethylene Glycol).
Propylene Glycol is an effective biocide and antifreeze only at concentrations above 25%.
Commercially available products range from 25 to 60 percent. They are usually labeled with a
temperature rating. “Minus 50” antifreeze is already diluted to 25%. “Minus 100” is a 60%
solution. Purchase the strongest antifreeze available. Use enough to ensure that the system
contains at least a 25% solution even after dilution with the residual water inside the water-
maker.
•
Step 1: Flush the system twice.
Push the “Auto Flush” button
on the MPC-3000 dis-
play, when the first flush has been completed,
press “Stop”
to cancel the 5 day interval
timer, then
press “Auto Flush” again
.
•
Step 2:
Open pressure relief valve
on the Clark pump.
•
Step 3:
Pour the propylene glycol into a bucket
. Follow the instructions on the con-
tainer.
•
Step 4:
Connect the hose
, using the garden hose barb fitting from your service kit,
to
the service 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: Pump as much as possible of the water remaining inside the water maker overboard.
Set the switches on the pump module to “Service System” and “Flush Auto”
to turn on the feed pump. Run the feed pump until you see antifreeze begin to appear in the
brine overboard hose.
Set both switches to Auto
to stop the feed pump.
•
Step 6:
Remove the quick disconnect fitting
from the brine discharge outlet of the
Clark pump, and
replace with the quick disconnect hose
from your service kit, and
lead the hose to the bucket.
•
Step 7:
Set the switches to “Service System” and “Flush Auto”
to circulate the
antifreeze for about ten minutes.
Clean Up:
•
Remove the quick disconnect from the Clark pump brine discharge, and
replace the
original hose that leads to the thru-hull
. You may at this point, if you choose to,
pump the bucket dry by using the feed pump switch. Stop when the bucket is empty.
•
Turn the service valve 180°
back to its original position, and remove the service hose.
•
Turn off the power to the system and the MPC control.
•
LEAVE THE PRESSURE RELIEF VALVE ON THE CLARK PUMP OPEN.
