NOTE
Collect all discharged liquids and recycle or dispose of it a proper
manner.
Choose the method that works best for you. In the following four methods,
the first two use a 50/50 nonpolluting biodegradable antifreeze/water solu-
tion:
 Pumping of anti-freeze solution into the overboard thru-hull fitting, and
discharging through the intake thru-hull fitting until all water is flushed out
and the solution no longer appears diluted.
 Use of the seawater pump to pump anti-freeze solution through the
system and discharging through the overboard thru-hull fitting until all wa-
ter is flushed out and the solution no longer appears diluted:
– Close seacock.
– Remove hose from strainer discharge.
– Raise hose above pump (so pump does not lose its prime).
– Pour in antifreeze solution.
– Pump solution through system.
– Drain the strainer and hose to seacock of water.
 Use of pressurized air injected at the overboard discharge fitting and the
water being discharged through the seawater intake fitting.
 Use of pressurized air to force water from the intake through the over-
board discharge.
Any method that causes the antifreeze solution to flow downward is the
method of choice. By this means, the antifreeze solution will displace any
water trapped and eliminate the possibility of freezing in hidden areas.
In addition, since the seawater pump utilizes a magnetically driven impeller:
 Remove the impeller from the wet end assembly.
 Wipe the impeller with an alcohol solution.
 Store the impeller in a warm, dry area until commissioning takes place.
