DESCRIPTION AND OPERATION
The PDFM-8A Fluorescent Paddle Dimmer is designed to replace a standard
light switch or dimmer. It controls fl uorescent loads only. To dim the
connected load move the slider down; to brighten the connected load move the
slider up. Press the top of the ON/OFF button to turn the connected load ON.
The Locator LED turns OFF and the load turns ON to the level set by the slider.
Press the bottom to turn the load OFF and the Locator LED ON.
Caution:
- Use only with dimming ballasts shown on the “List of Compatible
Ballasts” in the specifi cations..
- To reduce the risk of overheating and possible damage to other
equipment, do not install to control a receptacle, a motor-operated
applicance, or a transformer-supplied appliance.
Important Notes
1. Only one dimmer can be used in a 3-way/multi-way circuit.
2. It is normal for the dimmer to feel warm to the touch during operation.
3. Protect the dimmer from dust and dirt when painting or spackling.
4. Check new installations for short circuits prior to installing the dimmer.
- Disconnect power to the circuit by removing the fuse or turning the circuit
breakers OFF.
- Install a switch instead of the dimmer. Turn the switch to the ON position.
- Restore power to the circuit. If the circuit breaker trips, a short is
present.
- Operate the switch . If the light fails to turn ON and OFF with the switch,
the wiring may be incorrect.
- Correct wiring if necessary and retest.
- Install the dimmer only after the light operated properly with the switch.
5. To ensure full lamp life and optimum dimmer performance, some lamps
must be operated at full intensity for 100 hours prior to dimming. Refer to
individual lamp manufacturer’s instructions for more information.
SETUP
The dimmer may need calibration to accommodate low end trim requirements
for variations in ballasts. When the slider is set to the lowest dimming level (all
the way to the bottom) if the connected load turns OFF, you can calibrate the
dimmer. Follow these steps:
1. Disconnect power from the circuit.
2. Remove the wallplate.
3. Use a small, insulated
fl at-tipped screwdriver to
adjust the dial located on
the strap by the slot marked
CALIBRATION (see Fig. 8).
4. If the connected load does
not turn ON or is not bright
enough, turn the dial towards
(+) symbol to increase the
brightness. If the connected
load appears too bright turn
the dial towards (-) to reduce
the brightness.
5. Replace the wallplate.
6. Restore power to the circuit.
Repeat the above steps as necessary.
TROUBLESHOOTING
Lights are flickering
• Lamp has a bad connection.
• Check wire connections to make sure they are secured fi rmly.
• There may be a circuit wiring issue. You should always use a separate
neutral wire for the circuit connected to the dimmer. If two 120V hots
from the breaker box share the same neutral and one of them has a very
large load, it could cause a voltage drop on the other hot. This can cause
fl ickering.
Light does not turn ON
• Check to see if the circuit breaker or fuse has tripped.
• Check to see if the lamp is burned out.

INSTALLATION AND WIRING
WARNING
Disconnect power to the wall switch box by turning OFF
the circuit breaker or removing the fuse from the circuit before
installing the PDFM-8A, replacing lamps, or doing any electrical work.
1. Prepare the switch box
After the power is turned OFF at the circuit
breaker box, remove the existing wall plate
and mounting screws. Pull the old switch out
from the wall box.
2. Identify the type of circuit
You may connect the PDFM-8A to a single
pole or multi-way circuit. If you are unable
to clearly identify some or all of the wires
mentioned in this manual, you should consult
with a qualifi ed electrician.
In a 3-way circuit (Fig. 3) two traveler wires connect to both switches. Another
wire provides power from the circuit box to one of the switches. A wire
connects from one switch to the load. A ground wire may also be connected to
a ground terminal on the old switches.

Caution – For your safety: Connecting a proper ground wire to the dimmer
provides protection against electrical shock in the event of certain fault
conditions. If a proper ground is not available, consult with a qualifi ed
electrician before continuing installation.
3. Prepare the Wires
Tag the wires currently connected to the existing switch
so that they can be identifi ed later. Disconnect the wires.
Make sure the insulation is stripped off of the wires to
expose their copper cores to the length indicated by the
“Strip Gage” in Fig. 4 (approx. ½ inch).
4. Wire the dimmer
Connect the wires to the terminals on the PDFM-8A
dimmer(s) as indicated in either step 4a or 4b.
Note: When two wires connect to the same terminal
on the dimmer, both wires must be the same
gage (12AWG or 14AWG) (Fig. 5). If they are not the
same gage, you will not have a secure connection.
4a. Single Pole Circuit: Wiring one PDFM-8A ( Fig. 6)
• Connect the green or non-insulated (copper) GROUND
wire from the circuit to the green terminal
on the dimmer.
• Connect the power wire from the circuit (HOT) to the black terminal on the
dimmer.
• Connect the lamp power (LOAD) to the gold terminal on the dimmer.
• The second gold terminal is not used for a single pole circuit.

4b. 3-way/multi-way wiring (Fig. 7)
• Note: Only one dimmer can be used on a 3-way/multi-way circuit.
• Connect the green or non-insulated (copper) GROUND wire from the circuit
to the green terminal on the dimmer.
• Connect the power wire from the circuit (HOT) to the black terminal on
the dimmer.
• Connect one of the gold terminals to either of the remaining wires removed
from the switch.
• Connect the remaining gold terminal to the remaining wire removed from
the switch.
5. Put all the new switches into their wall boxes. Position the dimmer with the
word “TOP” right side up. Use the captive screws on the mounting strap to
secure the switches to their wall boxes.
6. Restore power to the circuit. Turn on the breaker or replace the fuse.
7. Attach the cover plates.
