L-2200 Maintenance
Seawater Strainer
Ensure that the pump receives adequate seawater flow
by regularly cleaning the strainer basket. Periodically
check the overboard discharge for a steady stream of
water. Check seawater intake speed scoop for obstruc-
tions. Make sure hoses are not looped, kinked or
crushed.
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 the 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,
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 seawater pump to pump anti-freeze solu-
tion through the system and discharging through the
overboard thru-hull fitting. Close seacock, remove
hose from strainer discharge, raise hose above pump
(so pump does not lose its prime) and pour in anti-
freeze solution. Pump solution through system. The
strainer and hose to seacock will also need to be
drained of water.
3. Use of pressurized air injected at the overboard
discharge fitting and the water being discharged
through the seawater intake fitting.
4. Use of pressurized air to force water from the intake
through the overboard discharge.
Note:
Collect all discharged liquids and recycle or dispose of in a
proper manner.
MAINTENANCE
Any method that causes the anti-freeze solution to flow
downward is the method of choice. By this means, the
anti-freeze solution will displace any water trapped and
eliminate the possibility of freezing in hidden areas.
In addition, since the seawater pump utilizes a magneti-
cally driven impeller, the impeller should be removed
from the wet end assembly, wiped with an alcohol
solution, and stored in a warm, dry area until commis-
sioning takes place.
