o
C (-58
F) propylene glycol based plumbing antifreeze to 2” below the top of the
prefilter cavity.
10. Unplug the outlet line on the System side to “open the outlet” by
removing the ¾” PVC plug. Remove approximately 4 litres (1 US gallon)
from the System into an empty propylene glycol based container. The
fluid in the System must be 2” above the bottom of the prefilter cavity.
Close the outlet line by replugging the outlet line with the ¾” PVC plug.
Discard the collected fluid in accordance with the manufacturers
directions and save the container.
11. Save all empty antifreeze containers for the spring.
12. If using a Stainless Steel Prefilter, replace the Stainless Steel Prefilter.
13. Replace the System Cap using the Cap Wrench.
14. Check the drain plug and the outlet plug are closed snug. Make sure there
are no leaks. The System is ready for the winter.
Note: The preservative will provide protection against freezing down to –40
°
C as
long as the proportion of propylene glycol to water is correct. The amount and
concentration of the propylene glycol solution has been selected to take into
account water that is not easily drained from the System. This procedure does
not protect the rest of the house from freezing, it only provides necessary
precautions for the MAYTAG Whole Home Water Filtration System.
Never mix MAYTAG MC1 Cleaning Solution with chlorine bleach.
