WARNING – KEEP ALL PERSONNEL CLEAR OF
TEST LOAD WHILE GENERATOR RUNNING.
• Construct a test load using a plastic bucket with the metal
handle removed (Fig. 9.1).
• Connect the test load to the GPP Electrosher as shown
(Fig. 9.2).
• Add tap water to the bucket.
• Set the “Mode Switches” on the GPP Control Box to AC &
120 PPS/ 60 AC.
• Start the generator.
• Control the GPP output with the “Emergency Shut Down”
switch or Foot switch.
• By turning the “Percent of Range” control up to 100% and
checking the amp meter on the GPP Control Box, the cor-
rect load can be determined. See below:
• The amp meter will increase to the maximum as you turn
up the “Percent of Range”.
• The load may be increased by slowly adding table salt to
the water in the bucket.
• If the load is too great for the range selected, the GPP will
operate erratically.
• If the amp meter starts to show a decrease in amps or is
erratic as the “Percent of Range” nears 100% the generator
is over-loading. The water may need to be changed, or
decrease the portions of electrodes immersed in the water.

IMPORTANT! Danger! High Voltage is present during test load procedure.
Every effort should be made to keep all personnel away from test load bucket. It
may be necessary to form a barricade around testing area and post appropriate signs
warning of High Voltage.
