Air conditioners utilized in Four Winns

models
are equipped with re verse cycle heat. Thus, some
heat effect can be derived from the unit. It must be
noted that the amount of heat that can be obtained
is limited by the temperature of the raw cooling water
pumped through the system. When the water tem-
perature drops to 40 degrees Fahrenheit, the output
is about 50% of the maximum. At 36 degrees Fahren-
heit, the output is very low.
NOTICE
During cold conditions, an alternate or supple-
mental heating system should be used.
Clean the sea water strainer often. Also, clean the
return air filter screens, located behind the louvered
doors and grills, at least once a month.
To winterize, refer to the manufacturer’s literature
included in the owner’s packet.
