RESULT IN FLOODING CAUSING SIGNIFICANT WATER DAMAGE OR
SINKING OF THE BOAT.
b) The condensing coil, the coil that connects to cooling "water in" and cooling "water
out", must be clear of any standing or trapped water. The best way to clear this coil is to
remove the "water in" hose from the coil and place a short piece of the same diameter
hose on the condensing coil. Blow through the short hose until no water comes out of the
"water out" thru-hull fitting on the outside of the boat. A compressed air source would
be ideal, should you have access to one.
c) Before replacing the condensing coil "water in" hose, go to where the pump is
located and remove the "water in" hose to the water pump. This is the hose between the
pump and the water strainer. Now return to the air unit and blow through the "water in"
hose forcing any trapped water back and through the pump. Again, a compressed air
source would be ideal, should you have access to one. This will clear the hose and the
pump. Replace both hoses to their original connections.
d) If you have any doubt about not clearing the condensing coil, you can add a legally
acceptable standard antifreeze or alcohol to the coil. Certain locales prohibit the use of
automotive antifreeze. Should you be using alcohol, insure you do not allow alcohol to
be in the water strainer. Clear plastic water strainer cups will cloud with alcohol.
e) Winterization is now completed. If the boat is to remain in the water, do not reopen
the sea cock until you are ready to again use the air conditioning unit when freezing is
no longer a threat.
WARNING
IF THE SEA COCK IS REOPENED WITH THE BOAT IN THE WATER AND
FREEZING OCCURS, WATER HOSES MAY RUPTURE AND FLOODING MAY
OCCUR CAUSING SIGNIFICANT DAMAGE OR SINKING OF THE BOAT
