GPP ELECTROFISHER
USER’S MANUAL
2016
1. First, check the engine oil level. Use 4-stroke
automotive detergent oil SAE 10W-30. Do not
overfill.
2. Refuel the engine outdoors. Keep away from
any open flame, pilot light, furnace, heater, or
clothes dryer. Stop the engine and allow it to
cool prior to refueling. Never fuel the engine
while it is hot or running to avoid fire, explosion,
bodily injury, or property damage.
3. Use gas with a minimum rating of 85 octane.
Do not use leaded gas because it produces
combustion deposits that may shorten the life
of the exhaust system. Do not mix oil with the
gasoline. Use a clean, properly marked and
approved safety container for storing fuel.
4. Fill the gasoline tank with clean fresh unleaded
gasoline. Do not overfill the tank. Leave half
an inch of the top of the tank to allow space
for expansion. Make sure the fuel cap is tightly
closed.
5. If fuel was spilled, wipe it away carefully. Wait
until the fuel has dried before starting the
engine.
6. Connect the
ANODE
and
CATHODE
to the
OUTPUT PWR
receptacle(s).
7. Plug the remote control cable (foot switch) into
the 4-pin receptacle.
8. Attach the generator cable/s into the male
plug/s labeled
INPUT PWR.
9. Place the anode and cathode in the water, not
touching each other.
10. Fully choke the motor to start. Open the choke
once the engine is running. Do not touch high-
voltage spark plug and coil terminals. While
spark voltages are not normally lethal, the
involuntary jerk of the hands caused by electrical
shock may result in injury.
11. On the Electrofisher set the
MODE
selector
switch to the desired mode. If you are not sure
which mode you desire, start with 120 pps DC.
12. Set the
PERCENT OF RANGE
to the minimum.
13. Set the
RANGE
selector switch to
LOW
.
14. Set
EMERGENCY SHUTDOWN
switch to
ON
15. Set the
ENUNCIATOR VOLUME
to
MIDRANGE
.
16. Activate the remote control switch. The high
voltage indicator lamp and audio alarm should
both come on and the display will show voltage
and current readings. Adjust the
PERCENT OF
POWER
control to achieve optimum response
by the fish. The duty cycle value will follow
OPERATING PROCEDURE
Before operating the power supply put on safety glasses and ear protectors. Remove wristwatch, rings
and any other jewelry. Do not operate the power supply while smoking. Do not operate while under the
influence of alcohol, drugs or medication.
17. Deactivate the
REMOTE CONTROL SWITCH
before changing the position of either the
RANGE
or
MODE
switches. Damage to
the range selector switch may result from
switching under load. Experimentation will
be required to learn what mode and voltage
settings are best for various water conditions
and types of fish.
the percent of power adjustment and the peak
readings will rise until the pulse encompasses
the highest part of the generator power wave.
The voltage metering circuit on the GPP is a
sensitive, high impedance circuit. When the
GPP is in AC Mode with absolutely no load (the
electrodes are not properly connected or out
of the water), the display may show a Voltage
Warning message. The display will return to
normal when the electrodes are put back into to
the water.
18. If your GPP has been running it hard, run it
for another five minutes under no load before
shutting it down. This allows the electrical
components to cool-down slowly, extending
their life considerably.
19. To avoid burns or fires let the power supply
cool before transporting. When transporting,
turn the fuel valve to the
OFF
position and keep
the engine horizontal to prevent fuel spillage.
When the power supply is transported over
a long distance or on rough roads, drain the
fuel from the fuel tank. Do not support the
power supply from the top of the frame for any
extended period of time.
OPERATING LIMITS
The GPP is designed to operate within limits that
protect the unit and the generator from serious
damage. When the output current exceeds a low
Warning level for the Range and Frequency Setting
it will start flashing the “High Current Warning”
screen but will continue to operate. If the output
current exceeds a higher Error level of current
output then the GPP display will show the “High
Current Error” screen, the High Voltage Indicator
will go out and the unit will stop operating. Release
the foot-switch, decrease the Voltage and/or Power
setting and depress the foot-switch to resume
output.
