INSTALLATION AND OPERATING INSTRUCTIONS
TO SET ON AND OFF TIMES: ON and OFF trippers close and
open all circuits simultaneously. Dial is graduated in one hour inter-
vals. There must be an ON and an OFF tripper for each day of the
week operations are desired. Place tripper on dial edge as shown in
diagram. Set point of each tripper at the desired operating time.
Hold tripper securely against dial and tighten knurled screw firmly
by hand. (Do not use pliers).
NOTE: Trippers are inter-changeable. With the knurl screw inserted
in the side marked ON, it will become an ON tripper. If the tripper is
turned over and the screw inserted in the side marked OFF, it
becomes an OFF tripper.
Be certain to select the proper day and notice whether the selected time is AM or PM. Minimum ON
time is 1 hour. Minimum OFF time is 2 hours. (There must be at least six hours between any two
OFF trippers).
TO SET DIAL TO TIME: Turn dial COUNTER-CLOCKWISE until correct time of day and day of week
is indicated by time pointer. For ACCURATE OPERATION, care must be used in setting dial to time.
Each notch advances the dial approximately 15 minutes.
DO NOT FORCE DIAL BACKWARDS.
TO OMIT A DAY: Remove both ON and OFF trippers from the dial for the day or days to be omitted.

cuit. Press down lever on left of nameplate to open it.
