rinse with water and consult a physician. Bicarbonate of soda
solution (one pound per gallon of water) will neutralize acid
spilled on clothing or material. Apply the solution until
bubbling stops, then rinse with clear water. In the event of acid
spill or accident, notify the Contracting Officer as soon as
practical.
c.
Utilize only approved hydrometers and thermometers for monitoring
the cells. Automotive hydrometers are not acceptable. Contractor
shall provide sufficient quantities of both instruments so as to
provide time efficient and accurate specific gravity and
temperature measurements.
][3.3.1.3
Battery Filling Instruction
After the UPS technical representative has inspected the UPS and
demonstrated proper operation of the UPS rectifier, Contracting Officer
will instruct Contractor to perform battery filling and charging in
accordance with the following instructions:
a.
Clean each cell thoroughly with a cloth dampened in clear water
and wipe dry with a clean cloth prior to filling the cells with
electrolyte.
b.
Ensure battery connections are properly torqued to manufacturer's
specifications. Torque values are given in mN-m inch-lbs. Take
and record, for cell-to-cell and terminal connections, detailed
micro-ohm resistance readings before placing battery in service.
Remake connections having a resistance of more than 10 percent
above the average. Test equipment and procedure must be approved
by the Contracting Officer.
c.
Electrolyte in the containers may have stratified. Contractor
shall ensure the specific gravity is between 1.205 and 1.220 by
agitating each electrolyte container until the specific gravity is
within the required range.
d.
Once a specific gravity between 1.205 and 1.220 is measured, and
the UPS rectifier is fully operational, remove the shipment vent
plug from each cell and fill cells with electrolyte. Use the
screw-in plastic shut-off nozzles provided with the electrolyte
containers. Contractor shall provide all hoses necessary for
filling the cells. Equipment used for filling the cells shall be
free of any metal to prevent electrolyte contamination.
e.
The filling height of the electrolyte shall not be higher than 6 mm
1/4 inch below the bottom of the low level line.
f.
Install a flame-arrestor vent in each cell immediately after
filling the cell. Lock in place with a one-quarter turn in a
clockwise direction. Then install a dust cover cap on the top of
each flame arrestor. CAUTION: Do not remove the flame arrestor
vents after initial filling.
g.
Allow the battery
to stand open circuit a minimum of four hours
after filling the
last cell. Add acid through the funnel of the
flame arrestor or
the electrolyte sampling tube to again bring the
electrolyte level
to 6 mm 1/4 inch below the bottom of the low
level line.
