To open and allow outside air flow, pull the
damper down about a 1/2" (13mm). To close,
push it up until it rests and seals against
the vent cover. The damper slide may need
lubrication occasionally if it is hard to open and
close. To lubricate, remove the cover and apply
a small amount of silicone grease around the
top of the damper tube.
NOTE: To prevent unnecessary wear on the motor, switch the vent
to the off position when the shut-off damper is in the closed position.
RECHARGEABLE BATTERY
Each Day/Night PLUS vent is equipped with a built-in replaceable
battery. The solar array keeps the battery charged during daylight hours
so that it can run the fan at night and during low light situations. The
Day/Night PLUS will run for up to 40 hours without sunlight on a fully
charged battery. Average battery life is 3-5 years, depending on climate
conditions.
NOTE: To maximize battery life, make sure it as fully charged as
possible during initial use. To fully charge, expose vent to the sun, (not
a light bulb) for 24 to 36 hours. This will insure a fully-charged battery.
(Depending on angle to the sun, weather conditions, and shadowing
of the solar array, the time necessary to charge the battery may vary.)
Reference the parts list on page 11 for replacement battery information.
INTAKE & EXHAUST FAN BLADES
The Day/Night PLUS comes with one intake and one exhaust blade.
Each blade is labeled on the hub with either intake or exhaust. To
exchange fan blades, gently pressing on the center of the hub to stop
fan blade. Reach inside and switch the motor off. Pull the existing fan
blade off and push the new one on, making sure you have the colored
dot showing.
CAUTION: A straight pull or push of the fan blade should be
exerted to ensure that you do not bend the motor shaft. When
replacing the fan blade be sure that the fan blade is not pressed
against the motor housing, as this will cause the fan to bind
reducing performance.
