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 aircraft
and vehicle fuels for Type I pumps, or
clear water for Type II pumps. Do not at-
tempt to pump corrosive liquids, or any
liquids which may damage the pump or
endanger personnel as a result of pump
failure.
GROUNDING
To eliminate electrostatic build-up when pumping
fuel, the pump must be grounded before opera-
tion. Ground the pump by attaching a ground wire
to a ground rod. Install the ground rod in accor-
dance with the National Electrical Codes and all lo-
cal codes. Be sure the clamp or fastener has made
a tight electrical connection with the rod.
Inspect and test the ground wire assembly
for conductivity. Replace broken or frayed
wire before resuming operation.
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
mounted. Check that the pump is properly lubri-
cated (see LUBRICATION in MAINTENANCE
AND REPAIR).
This pump is self-priming, but should never be op-
erated unless there is liquid in the pump casing.
Never operate this pump unless there is
liquid in the pump casing. The pump will
not prime when dry. Extended operation of
a dry pump will destroy the seal assembly.
Add liquid to the casing when:
1. The pump is being put into service for the first
time.
2. The pump has not been used for a consider-
able length of time.
3. The liquid in the casing has evaporated.
Once the pump casing has been filled, the pump
will prime and reprime as necessary.
After filling the casing, reinstall the fill
cap. Do not attempt to operate the pump
unless all connecting piping is securely
installed. Otherwise, liquid in the pump
forced out under pressure could cause
injury to personnel.
To fill the pump, remove the priming cap at the top
of the casing and add clean liquid until the pump is
filled. Replace the priming cap before operation.
The amount of time required to prime the pump va-
ries with relation to the following:
1. Length of suction hose.
2. Height of pump above source of liquid to be
pumped.
3. Liquid temperature.
4. Type of liquid being pumped.
The lesser the values of items 1, 2 and 3, the short-
er the priming time.
Emergency Priming
The priming operation heats the liquid in the pump
casing. If the liquid heats to the point of vaporiza-
