OPERATION - SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, labels and
decals attached to the pump.
This pump is designed to handle water,
gasoline or other petroleum products.
Do not attempt to pump corrosive or
highly volatile liquids which may dam­
age the pump or endanger personnel as
a result of pump failure.
The following information must be established
prior to beginning a cleaning job:
a. The size of the tank to be cleaned.
b. The direction of the tank's longitudinal axis.
c. The diameter of the tank's fill pipe through
which the standpipe is inserted.
d. The location of the fill pipe with respect to the
length of the tank.
e. Availability of the proper electrical service and
receptacle required for safe operation of the
unit.
This information is necessary to properly install
and operate the pump and to direct the hose as­
sembly within the tank. The hose assembly must
be directed along the bottom of a horizontal, cylin­
drical tank, and centered within an 18 to 24 inch
wide (457 to 610 mm) cleaning path.
The hose assembly is designed so that the hose
nozzle travels straight out from the standpipe and
along the bottom of the tank. The direction of
nozzle travel is adjusted to the tank by rotating the
reel and standpipe assembly to align the cleaning
path with the longitudinal axis of the tank.
Attempting to climb a side or end wall will
cause the hose and nozzle assembly to flip
over and create a severe tangling situation.
Therefore, it is essential to establish the rel­
ative size and position of the underground
tank to properly operate the hose assem­
bly.
The nozzle will precisely follow any horizontal irreg­
ularities of the tank bottom The hose assembly is
not, however, capable of climbing the side or end
walls of the tank.
After the pump has been installed, make
certain that the pump and all piping or
hose connections are secure before op­
eration.
PRIMING
Install the pump and piping as described in IN­
STALLATION. Make sure that the piping connec­
tions are tight, and that the pump is securely posi­
tioned.
Remove the dust cap on top of the discharge port
and fill the pump casing with liquid. Be sure to rein­
stall the dust cap after filling the pump casing.
Once filled, the pump will prime and reprime. Be­
tween operations, liquid in the pump may be lost
through evaporation or by spillage if the pump has
been moved. Check the priming chamber to see if
it is full before the pump is started.
Leakage
No leakage should be visible at pump mating sur­
faces, or at pump connections or fittings. Keep all
line connections and fittings tight to maintain maxi­
mum pump efficiency.
