Installing the Day/Night PLUS

It is also recommended to periodically clean the solar array with a
mild cleaner to ensure the vent charges continuously and receives
maximum sunlight. If after a few years of operation the battery
is no longer performing at peak performance, replace it with a
rechargeable C-cell battery rated at 2800 mAh or greater.
TROUBLE SHOOTING
STOPS RUNNING:
• Check the On-Off Switch – Make sure the switch is on.
• Check the Solar Array – Make sure the solar array is not covered
up by shade
• Check Fan Blade – Make sure the fan blade has not been pushed
up the motor shaft too far so that it is pressed against the motor
housing. This will cause the fan to bind, reducing performance, and
may also cause the vent to become “noisy”. To remedy, simply pull
the fan blade away from the motor housing (aprox. 1/16") until fan
functions normally.
• Check/Replace the Battery – If the switch is on and the vent is
not working, the battery may be dead. A dead battery short
circuits the solar array and will not deliver power to the motor.
You can replace the battery by removing the solar array in the
center of the cover. Remove the three screws around the edges
of the array cover. Be careful not to lose the small O-rings on the
screws. Lift off the array cover, being very careful not to over
extend or break the wires that attach the array to the vent. Lift off
the array cover slowly and carefully. If needed, a small,
flat-blade screwdriver may be used to pry up the solar array cover
(there are two pry slots located at opposite ends on the edge of
the array cover). Remove the rechargeable battery.
TEST the vent without the battery in it by placing the array in direct
sun to see if the motor turns (make sure the switch is on). If the
motor turns, the battery is dead.
Replace the battery with a 1.2 volt C-cell nickel-metal hydride
