Slinger Ring on Outdoor Fan Blade
The water that is collected through the normal
process of air conditioning is collected in the rear
base pan. To aid in dissipating this water, the
outdoor fan blade has a ring around the blade
that picks up the water and "slings" it onto the
outer coil. This assists in removing heat from the
coil when the Zoneline is in cooling mode.

When operating in the heat-pump mode, defrost
water is also collected in base pan, but because
outdoor temperatures may drop below freezing,
the water level could cause the outdoor fan
blade to freeze in the pan. To prevent this from
occurring, a thermostatically operated drain pan
plug is utilized. Located in the base pan, when
the air temperature is above 65°F it is closed and
opens when the temperature drops below 45°F,
lowering the water level in the base pan.
