Winterizing with Propylene Glycol
See description of propylene glycol formulations, and flushing from system, on page 44-45.
1. Turn the yellow service valve on the feed pump module to OFF (horizontal, see photos).
2. Push Auto Store to fresh water flush the system. Repeat, to flush the system twice.
3. Connect the inlet service hose to the feed pump module (above the yellow service valve) and
lead the hose to the bottom of a bucket. Connect the brine service hose, and run it into a sec-
ond container.
4. Turn the yellow service valve on the feed pump module to the SERVICE position.
5. Pour 1 gallon (4 liters) of propylene glycol of appropriate concentration (see pages 46-47) into
the bucket with the intake service hose.
6. Make sure the pressure relief valve on the Clark Pump is OPEN 1/2 turn (un-pressurized).
7. Run the feed pump using the manual switch on the MPC control box until about a gallon of
water has flowed from the brine discharge service hose, or antifreeze appears. Propylene gly-
col will look slightly different, and feel more slippery, than water. Stop the pump. Add more
propylene glycol to the intake bucket if necessary.
8. Lead the brine discharge service hose into the intake bucket of propylene glycol. The service
hose will now draw propylene glycol from the bucket, and the brine discharge service hose
will return it. Run the feed pump and circulate the antifreeze for 10 minutes.
9. Stop the feed pump. Close the seawater intake and turn the yellow service valve to OFF. Drain
the seawater strainer and the hose leading to the feed pump module. Disconnect the product
tubing from the membrane housing and blow residual water out of the tubing. Empty the
charcoal filter housing and flush water lines.
Your watermaker is now protected from biological growth and freezing for one year.
