PAGE A − 2 SAFETY
Do not operate the pump against a
closed discharge valve for long periods
of time. If operated against a closed dis-
charge valve, pump components will
deteriorate, and the liquid could come
to a boil, build pressure, and cause the
pump casing to rupture or explode.
Overheated pumps can cause severe
burns and injuries. If overheating of the
pump occurs:
1. Stop the pump immediately.
2. Ventilate the area.
3. Allow the pump to completely cool.
4. Check the temperature before
opening any covers, plates,
gauges, or plugs.
5. Vent the pump slowly and cau-
tiously.
6. Refer to instructions in this manual
before restarting the pump.
Do not remove plates, covers, gauges,
pipe plugs, or fittings from an over-
heated pump. Vapor pressure within the
pump can cause parts being disen-
gaged to be ejected with great force. Al-
low the pump to completely cool before
servicing.
Overheating may produce dangerous
fumes. Use extreme caution when vent-
ing the pump, or when removing covers,
plates, plugs, or fittings.
Never run this pump backwards. Be cer-
tain that rotation is correct before fully
engaging the pump.
