1. Use a Y-type line strainer in oil supply lines. Locate
as close to the meter inlets as practical and where
they are easily accessible. Mount the strainer body
horizontally with the clean-out plug pointed down.
See Fig. 4. Periodically, relieve the pressure, and
remove and clean the metal strainers.
To order a 3/4 in. npt(f) line strainer, order Part No.
101078.
To order a 1/2 in. npt(f) line strainer, order Part No.
110877.
INJECTION HAZARD
To reduce the risk of serious injury
whenever you are instructed to relieve
pressure, always follow the Pressure
Relief Procedure on page 8.
2. See Fig. 5 for installation dimensions for the
supply line. Space the line ends to be adjacent to
the pump location. For annealed steel or copper
tubing lines, use a straight male coupling elbow
and a shutoff valve. For iron pipe, a shutoff valve
may be used instead. The shutoff valve must close
off 1/2 in. npt(f) openings for the Fire-Ball 300
pump, and it must close off 3/4 in. npt(f) openings
for the Fire–Ball 425 pump.
