GE Box-Timer GE Time Switch 15251 15252 and 15253 - Manual (Page 2)

GROUNDING:
This enclosure is of plastic construction and does not require a ground
connection and does not require bonding in pool applications.
This enclosure does not provide grounding between conduits. When using
non-metallic conduit or cable, connect the ground wires of all cables together
with a wire nut. When metallic conduit is used, use grounding type bushings
and a jumper wire between each conduit.
OPERATING INSTRUCTIONS:
When the Time Switch is installed and power applied, the timer’s dial will turn
clockwise maintaining time. The pointer on the face of the dial points to the
current time
1. Locate the segments around on the outer edge of the timer’s dial. These
segments, each representing 30 minutes, can be pushed down and away
from the edge of the dial (try using the tip of a pen or pencil). Conversely,
segments that have been pushed down can be easily pushed back up by
hand. Be sure all segments are pushed up before programming. Select a
time period (or periods) you want the device turned on, then push down
ALL the segments that fall on or within that time period. For example,
to have the timer turn a device on at 10PM and off at 2AM, push down
the segments representing 10PM and 2AM, and ALL the segments in
between. You may need to turn the dial clockwise to access the desired
segments.
2. Rotate the timer’s dial clockwise until the pointer on the face of the dial
points to the current time of day. Note: Nighttime hours (from 6:30 PM to
6:30 AM) are highlighted with a grey background.
3. Set master switch to the TIMER position.
4. To override timer program and control output load manually:
• set master switch to OFF (center position) to turn load OFF
• set master switch to ON (bottom position) to turn load ON
5. This is a Timer Control and should not be used for power disconnect.
Turn power off at main panel before servicing this switch or the
equipment it controls.
In case of power failure, reset the time of day as explained in step 2.
