FEATURES & OPERATION 

ON-OFF SWITCH 

The Day/Night PLUS comes with an on-off 
switch which is located inside the fan housing. 
To operate, gently place your finger on the hub 
of the fan until it stops rotating, then just press 
the rubber covered switch on or off. Setting the 
switch to the off position cuts all current from the 
solar array and battery to the fan motor. All the current produced by 
the solar array is therefore used to charge the battery. 

SHUT-OFF DAMPER 

The Day/Night PLUS is equipped with a green water shut-off damper 
which can be operated from below. There are two ears on the inside 
edge of the fan housing.
