Mix citric acid:
Perform this step only if ROWPU will be operated 20 or more hours before changing
sites. Otherwise, proceed to step aa.
Pour 0.75 pounds (340 grams) of citric acid into pail marked CITRIC ACID.
Add brine (if available) or raw water to pail marked CITRIC ACID to the 3-gallon mark.
Stir with wooden paddle for 1 minute.
Pour solution into 5-gallon container marked CITRIC ACID.
Check chemical solution levels by pulling level indicators up, and then gently letting go. Indicators should
remain raised and read approximately 1/4 full.
Ground the ROWPU with ground rod kept on outside bottom of the control panel (fig. 2-39). First remove the
rod with the bolt screwed into the coupler. The bolt keeps from damaging the coupler when the rod is driven into the
ground. Drive the first 3-foot section into the ground with the 8-pound hammer, or use the slide hammer.
ELECTRICAL HIGH VOLTAGE CAN KILL YOU
Electrical high voltage cannot be seen but it can kill you. Electricity is
unlike most other dangerous things you can come in contact with
because it gives no warning and no symptoms to be wary of. Its effect is
immediate. It can kill you, render you unconscious, or severely burn you.
To ensure your safety and that of other maintenance personnel, always
observe the following precautions:
ALWAYS make sure the unit is properly grounded.
Take extreme care to prevent injury to fingers or hands when driving the
ground rods. Do not place hands between the ram and drive collar.
Gloves should be worn. Be sure all connections are tight so as to avoid a
possible spark between the units and ground rod.
ac. When the first rod coupler is approximately 6 inches above ground, remove the driving bolt. Screw a new
length of ground rod into the one already in the ground and drive it in as with the first section. Continue this process until
there are 8 feet of rod in the ground.
When done driving the ground rod, connect the rod sticking out of the earth to the GROUND lug located on the
ROWPU frame immediately below the ROWPU electrical cable connections. Use the ground strap provided.
