Mermaid Air Conditioner - Manual (Page 26)

periodic checks of all water connections and to close the "water in" sea cock whenever
you leave the boat for extended periods of time.
b) Your water strainer will require cleaning on a regular basis. The time between
cleanings will be dependent on the condition of the water your boat resides in, the
amount of time your air unit operates, and the physical size of the strainer you have
installed. After you have had your unit for a few months you will develop a feel for how
often you should clean the strainer basket.
2. Air System:
a) There is little maintenance required for the air system. The main item is the air filter
located on the front of the air unit evaporator. This filter will require cleaning on a
regular basis. As with the water strainer, the time between cleanings will be dependent
on operating time and environment. For instances, if you have a pet, the time between
cleanings will be shorter due to the pet hair that will be pulled onto the filter. The filter is
easily cleaned by washing it in plain tap water. Never operate the air unit for extended
periods of time without the air filter in place. The debris that would normally be
collected by the filter will become lodged in the evaporator coil cooling fins and will
gradually reduce the efficiency and performance of your air conditioner to a point that it
will require professional acid bath cleaning.
b) When cleaning the filter, also wipe the unit off with a dry cloth to eliminate dust build
up. Check that the air ducting has not sagged or loosened around the air collar or air
vents.
3. Electrical System:
a) Unless you have some reason to suspect an electrical problem, there is no maintenance
required for the electrical system; However, as always, it is prudent to do cursory checks
on all equipment on your boat as you perform your general maintenance on various
equipment and systems throughout the year.
B. WINTERIZATION:
1. Air Conditioning Unit and Water Pump:
a) If your boat is in the water, you must first close the "water in" sea cock before
proceeding with winterization.
