9. VISCOSITY – The maximum pumped fluid viscosity is 250 cen-
tipoise.
10. DUTY CYCLE – Motor and pump are designed for continuous
operation in a 70°F (21°C) environment while pumping against 15
psi (1.05 bar) discharge pressure.
Beyond these parameters, an intermitted duty cycle is recommend-
ed to maximize pump life. In normal operation, motor case will get
hot. Prolonged contact with motor could cause a burn on human
skin.
11. START-UP AND OPERATION – Check level of fluid in supply
tank. Open all valves in system. Switch pump electrical circuit to
"on" position. Flow will become steady as air is bled from system.
For pumps equipped with pressure switch, close discharge valve
after flow becomes steady fluid stream. Pump should shut off soon
after closing valve. Pump is now ready for automatic operation.
Pump will start when valve is opened and stop upon closure of
valve. If pump is to be inoperative for a considerable period of time,
flush pump with water, turn off electrical circuit to pump, and bleed
system pressure by opening discharge valve.
