Wire in accordance with instructions. Depending upon the specific installation, you may find it more convenient to have wiring completed before attaching the base. Replace terminal cover and push timer firmly onto plug-in base. Now replace housing and secure with screws.
NOTES:
- The MIL 72A may also be DIN rail mounted—simply break out housing part that fits over rail on each side.
- 24V quartz unit will operate on 6VDC, 12VDC, or 24VDC
For stand-alone installations, the unit may be surface mounted inside an indoor enclosure which is available from Intermatic Incorporated or your wholesaler.

WIRING
- Disconnect the power.
- Wire according to the proper voltage marked on the unit. Wiring to incorrect voltage will void the warranty.
- Connect wiring according to the wiring diagram. The terminals on the MIL 72A sub-base will accommodate 10 to 24 AWG wire.

PROGRAMMING
The weekly program dial shows the seven days of the week and AM/PM imprints for each day. The 24-hour dial has quarter-hour divisions and AM/PM indications.
The time switch is set by pushing the captive trippers to the outer ring position for the entire period that the load is to be turned ON, i.e., fifteen minutes for each tripper on the 24-hour dial and 2 hours for each tripper on the 7-day dial. When the tripper is pushed to the inside, the switch is in the OFF position.
SETTING TIME
TO SET THE CURRENT TIME (AND DAY OF WEEK ON 7 DAY UNITS), TURN THE MINUTE HAND CLOCKWISE. DO NOT SET THE TIME BY ROTATING "OUTER" DIAL.
Turn the minute hand clockwise until the day of the week (7-day timer) and the time of day on the outer dial is aligned with the triangle marker on the inner dial (two o'clock position).
Example for 7-day program dial Monday 10:30 AM. Turn the minute hand clockwise until Monday 10:30 AM is aligned with the triangle on the inner dial. The hour and minute hand will show exactly 10:30.
Example for 24-hour program dial 10:30 AM. Turn the minute hand clockwise until 10:30 AM is aligned with the triangle on the inner dial. The hour and the minute dial will show exactly 10:30.
MANUAL OVERRIDE
All MIL 72 units are available with an optional 3-way manual override (type designation "H").
