GENERAL SAFETY INFORMATION:
1. Mount the time switch in the desired location using the
three mounting holes which are provided. Mount the
time switch at eye level, if possible, providing sufficient
room to the left of the enclosure for the cover to swing
open fully. (See Fig. #2). The time switch mechanism
does not need to be removed from the enclosure to
mount the time switch since the top mounting hole is
a slotted type mounting hole. Secure a screw or other
fastener at eye level. The head of the screw of fastener
should be slightly larger than the narrow portion of the
slotted hole to ensure that the time switch is securely
held in place. The remaining two mounting holes
provide a means to secure the time switch.
2. If you do remove the mechanism, refer to Figure #3 and
remove the mechanism from the case by depressing
the catch at the top of the case and pulling out.

3. Replace the mechanism in the case if it has been
removed, making sure to engage ribs at sides of
mechanism between ears at sides of case before
snapping in place.
4. Lift the left side of the insulator off of the retaining
post and pivot it up and away to expose the terminal
screws.
5. Strip the supply and load wires by removing 1/2 inch
of insulation. DO NOT USE ALUMINUM WIRE. Insert
the wire ends under the proper terminal plates and
tighten the screws firmly. Use any size wire AWG #10.
Connect ground wire to grounding terminal at bottom
of case.
6. Replace the plastic insulator.
7. Follow instructions for battery installation. Be sure
that the battery is functioning properly. This can be
checked by seeing that the display is visible. If the
display has scrambled information, check to be sure
that the polarity orientation of the battery is as shown
on the cover label, then press the RESET switch and
hold for at least two seconds. Note that the battery
can easily be replaced without removing the time
switch mechanism or field wiring. Simply press in and
downward (in the direction of the arrow) on the battery
cover which is identified with the word "Battery".
It is recommended that the battery be replaced with
a "AA" industrial grade alkaline cell at two to three
