Maintenance
➤ Power the pump and circulate the cleaning solution through the condenser coil
for 15 – 45 min, depending upon the size of the coils and the extent of the con-
tamination.
Visual inspection of the solution in the container should indicate when the con-
tamination removal has stopped.
➤ Circulate fresh water through the coil to flush any residual acid from the system.
➤ Restart the system.
➤ Check operational parameters to ensure thorough cleaning has taken place.
➤ Additional cleaning may be necessary with extreme contamination.
10.4 Return Air Filters
➤ Check the return air filter about once a month and clean as necessary.
➤ To clean the filter,
– remove it from the return-air grille,
– rinse with water,
– air dry and
– reinstall.
➤ If your kit is supplied with a filtered return-air grille, the filter attached to the unit's
evaporator must be removed.
Two filters are not better than one, as the reduced air flow will decrease perfor-
mance and possibly freeze the evaporator coil.
10.5 Winterization
I
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 solution:
•
Pumping of anti-freeze solution into the overboard thru-hull fitting, and discharg-
ing through the intake thru-hull fitting until all water is flushed out and the solution
no longer appears diluted.
