Priming The Pump
A tee installed in the discharge opening of the pump,
and provided with a priming plug at the top position,
will enable you to fill the pump with liquid. Once filled
and the priming plug replaced, the pump will prime. The
pump should prime itself time after time, as long as the
built-in check valve functions.
Service
Never run pump dry. Running pump without
water may cause pump to overheat, damaging seal and
possibly causing burns to persons handling pump. Fill
pump with water before starting.
Never run pump against closed discharge. To
do so can boil water inside pump, causing hazardous
pressure in unit, risk of explosion and possibly scalding
persons handling pump.
Maintenance
Little or no maintenance to pump is required other than
possible replacement of shaft seal after a reasonable
period of operation (see Page 8).
Lubricate motor according to motor manufacturer’s
in-structions. Periodic greasing is required for
mostmotors.

and cause switch malfunction.
