INSTALLATION INSTRUCTIONS:
This spring wound timer is as easy to install as a light switch in a standard 2-1/2 inch deep vertically installed junction box in place of (or to replace) a standard single pole, 3-way or double pole single throw (depending on timer model) wall switch. This spring wound timer will automatically turn off lights, fans, air conditioners and other loads after a preset timing period.
CAUTION: This timer should not be used in precision timing applications where inaccurate timing could have dangerous consequences (i.e. sun lamps, sauna, etcetera).
INSTALLATION
Depending on the type of spring wound timer you have, you may need to supply a standard single or multi-gang wall switch plate with either a toggle opening or a decorator type opening. If your timer is supplied with a metallic silver plastic time dial wall plate (models with FF prefix), see illustration “A”. If your timer is supplied with a small ivory, white or other colored plastic time dial plate (models with FD prefix), you will need to supply a standard toggle or decorator design wall switch plate and see illustration “B1” or “B2”.
-
Be sure to turn off electrical power at breaker or fuse panel for safety during installation.
-
Remove wall plate and disconnect switch from vertically installed junction box.
-
Strip end of wires 1/2 inch long as per strip gauge on back of timer.
-
Insert stripped end of wires under the pressure plate of terminal screws on the side of timer (terminal screws provided in plastic bag). SCREW DOWN TIGHTLY. Use COPPER wire **ONLY
**
-
Insert wired timer into a 2-1/2 inch deep standard wall junction box with “TOP” (indicated on front of timer) in proper position and fasten timer to junction box using the two long screws provided.
“FF” Models Only (See Illustration “A”) -
Slip time dial plate over threaded extension with “OFF” mark of time dial plate on top as marked on front of timer (see illustration “ A ”).
-
Fasten time dial plate securely to timer with stamped nut provided (see illustration “ A ”).
“FD” Models Only (Illustration B1 and B2) -
Illustration “B1” – Place standard toggle or decorator plate on timer, do not over tighten.
NOTE:
If you are using a standard toggle switch plate, illustration B1, it is not necessary to use the two screws provided with the switch plate. The nut provided with the timer will securely hold the switch plate. The screws, if used, must be self-tapped into the timer body and will require a gentle inward pressure while turning the screw firmly in order to self-tap into the timer body. If using a decorator style wall switch plate, illustration B2 threaded holes are provided in the metal tabs at the opposite ends of the timer. Fasten the decorator style plate using the two screws provided with the switch plate, but do not over tighten. -
Slip plastic time dial plate over threaded extension with “OFF” mark of time dial plate on top as marked on front of timer and fasten securely to timer with nut provided. DO NOT OVER TIGHTEN. (See illustration “B1 ”).
-
Push knob on timer shaft so knob pointer centers on “OFF” on dial plate. The knob has a “D” shaped hole which matches the “ D ” shaft on the timer.
-
Restore power.
HOW TO OPERATE YOUR TIMER:
FOR AUTOMATIC TIMING OPERATION : Turn timer clock-wise to time desired. Timer will turn “OFF” load at the end of preset timed period. Note that timers (SPDT) wired for reverse action applications will turn load “ON” at end of preset timing period
TO BYPASS TIMER : (Models with “hold” feature only.) – Turn counter clockwise to stop. At this position, timer does not operate, but switch is “ON” until knob is manually returned to “OFF”.
APPLICATIONS
The variety of pole configurations available allow Intermate spring wound
timers to be used for many applications as detailed to follow:
SPST
Used to break the hot side of any 120 volt load such as”
- Coffee Pots
- Air Conditioners
- Lighting
- Ventilating Fans
SPDT
For applications requiring 3-way switching (2 timers or timer and 3-way
switch) or reverse action applications. Reverse action applications allow a
load to be turned “OFF” for a limited time, after which the load will
switch back “ON”. Three way applications are used for controlling a load
from two different locations such as:
- Hallways
- Corridors
- Self-storage Facilities
- Upper Level/Lower Level
Reverse Action Switching
DPST
For applications where both sides of a 208, 240 or 277 volt load must be
switched. Applications such as:
- Large Horse Power Motors
- Pumps
- Indoor Lighting
- Outdoor Lighting
