4) Dipswitch configuration
WARNING: Failure to properly configure the dipswitch will damage the unit and void the warranty. Before
installation, complete the following steps to select the proper dipswitch configuration.
1. Determine the input voltage.
2. Do not apply power to the timer prior to setting the input voltage dipswitch.
3. Set the dipswitch according to the diagram below [FIG 4].
6) Operating instructions
When the timer switch is installed and power applied, the timer’s dial turns clockwise to maintain time.
The pointer on the face of the dial indicates the current time.
1. Be sure all segments are pulled up before programming. Select the period or periods you want the
device turned on.
2. The segments around the outer edge of the timer’s dial represent 30 minutes and can be pushed down
using your finger or the tip of a pencil. Segments can be easily pulled up by hand. Up position = OFF,
down position = ON. Then, push down ALL the segments that fall on or within that period.
[FIG 5]
3. Rotate the timer’s dial clockwise until the pointer on the face of the dial indicates the current time.
Note: Nighttime hours from 6:30PM to 6:30AM are highlighted on a gray background.
4. Set master switch to the TIMER position [FIG 6]:
5. This is a timer control and should not be used for power disconnect. Turn power off at main service
panel before servicing this timer or the equipment it controls.
In case of power failure, reset the current time as explained in previous steps.
3) Choose a suitable mounting location
Mounting the box for drywall
1. Hold the box in place and use the three holes highlighted to mark position on the
mounting surface
[FIG 3].
2. Drill a 3/16in. size hole for the drywall anchors at each marked location.
3. Insert an anchor in each hole, and gently tap the open end of anchor with a hammer until the
anchor is almost flush with the wall.
4. Mount the box to the anchors using the supplied screws.
Mounting the box for solid surface
1. Hold the box in place and use the three holes highlighted to mark position on the
mounting surface
[FIG 3].
2. Drill a 3/32 in. hole at each marked location.
3. Mount the box to the surface using the supplied screws.
IMPORTANT! Always close the rainproof door after use.
