INSTALLATION AND OPERATING INSTRUCTIONS

TO SET ON AND OFF TIMES:
Light trippers turn ON. Dark trippers turn OFF. Place tripper on
dial edge as shown in figure and set point of each tripper to
desired operating time. CAUTION: Note if selected time is AM
or PM. Hold tripper against dial edge and firmly tighten
knurled screw.

TO SET DIAL TO TIME: Turn dial counter-clockwise until correct time is indicated by arrow on name-
plate.

FOR MANUAL OPERATIONS: Press down lever on right of nameplate to turn ON. Press down lever
on left of nameplate to turn OFF.

TO OMIT ON OPERATION: 7 spoke wheel at lower left of 24 hour dial moves ahead once each day,
about 5 hours before the first ON tripper is set to operate. Insert brass knurled screws in appropriate
spokes on days when ON operations are to be omitted.

TO SET OMITTING WHEEL TO CORRECT DAY: Hold down OFF lever on left of
nameplate. The red stud on this lever is the day-indicator. If the ON tripper has
already passed the omitting wheel, turn omitting wheel clockwise until the present
day of the week is indicated. If ON tripper has not passed omitting wheel, set omit-
ting wheel so preceding day is indicated (24 hour dial turns counter-clockwise).
