F. WINTERIZATION PROCEDURE
Tools/Supplies Required
For all Systems you will need:
•
Cap Wrench
•
Adjustable wrench
•
Nut driver
•
3 US gallons (12 litres) plumbers antifreeze that is
propylene glycol based and rated for -58°F (-50°C).
•
1 - ¾” MNPT PVC plug
•
1 - ½” MNPT PVC plug
WARNING:
Never use AUTOMOTIVE
type antifreezes when winterizing the System. This may
result in serious injury or death.
Only plumbing antifreeze, consisting primarily of
propylene glycol with no ethanol or other alcohols,
rated for -58°F (-50°C), may be used to winterize the
System. The use of less-expensive
‘non-propylene glycol based’ plumbing or RV
antifreezes may damage the System’s internal
components voiding all warranties. This may also
result in serious injury or death.
Plumbing antifreeze containing propylene glycol will
provide protection of the System against freezing to
-40°F (-40°C) as long as the proportion of antifreeze
to water is correct. This procedure only protects the
System from freezing and does not protect the rest of
the household water distribution system.
Propylene glycol based antifreeze is available at most
hardware stores.
1
Close the Inlet Valve. Completely drain the System and
household piping. To drain the System, refer to the Controller
Functions section under D. OPERATIONS on how to perform a
Manual Flush. To drain the household pipes, open a cold water
tap (on the lowest level of the home) and leave until the tap
only drips. Turn off the tap when the pipes are drained.

Remove the drain hose and Nylon Elbow from the Drain
Solenoid Valve and install a ½” MNPT or ¾” MNPT PVC plug
(depending on the size of the port) into the Drain Solenoid
Valve.
3
Drain the filtered water from the System by
disconnecting the Outlet Stainless Steel Flex Hose where it
connects to the home plumbing, and drain into a large bucket.
Plug the Flex Hose and System by installing a ¾” MNPT PVC
plug.

Outlet Fitting Assembly installed in standard configuration
shown. Systems equipped with the Surface Water Option Kit
have different Outlet Fitting Assemblies.

If an External Prefilter has been installed, open the Mini
Ball Valve on the bottom of the housing and allow to drain.
Press the red button on the External Prefilter head to speed up
draining. Unscrew the housing from the head and remove the
External Prefilter cartridge from the housing, and discard. Do
not install a new filter cartridge. Re-attach the filter housing to
the head.
