MAINTENANCE
Sea Water Strainer
Insure that your pump receives adequate sea water flow by regularly cleaning the strainer basket.
Periodically check the overboard discharge for a steady stream of water. Check sea water intake speed
scoop for obstructions. Make sure hoses are not looped, kinked or crushed.
Sea Water Pump
If the capacity of your air conditioning system is greater than or equal to 48,000 BTU/hr, the sea water
pump is most likely air cooled and will need occasional oiling. See manufacturer’s labeling on the pump
for maintenance instructions.
Condenser Coil Cleaning
Coils can become fouled over a period of time due to marine growth or scale build-up. This both
obstructs water flow and prohibits proper heat transfer. To clean coils, flush with a 5% muriatic or
hydrochloric acid and fresh water solution. Disconnect system hoses from coil and pump solution
through until clean. Rinse with fresh water and reconnect hoses. Follow manufacturer’s safety
guidelines for all cleaning solutions.
Return Air Filters
Check the return air filter about once a month and clean as necessary. To clean the filter, remove it
from the unit/grille, rinse with water, air dry and reinstall.
Winterization
There are several methods of winterization, some of which work better than others. The four various
methods employed using a 50/50 non-polluting biodegradable anti-freeze/water solution are:
1. Pumping of anti-freeze solution into the overboard thru-hull fitting, and discharging through the
intake thru-hull fitting.
2. Use of the sea water pump to pump anti-freeze solution through the system and discharging
through the overboard thru-hull fitting. Close sea cock, remove hose from strainer discharge, raise
