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 for 12 minutes using the manual operation switch. Set the

switch to “Service.” The water maker will begin to flush itself. To stop the flush Set

the switch to “Run Auto”.

• 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 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: Pump as much as possible of the water remaining inside the water maker overboard.

Set the switch on the pump module to “Service” to turn on the feed pump. Run the

feed pump until you see antifreeze begin to appear in the brine overboard hose. Set the

switch to “Run 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 switch to “Service” to circulate the antifreeze for about ten minutes.

Switch to “Run Auto” to stop the pump.

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.

• LEAVE THE PRESSURE RELIEF VALVE ON THE CLARK PUMP OPEN.
