Note on Motor Voltage Connections:
In all cases, motors are designed for operating voltages plus or minus
10% of the normal rating (see SPECIFICATIONS). Single voltage
motors are supplied fully connected and ready to operate.
1. Check to be sure the voltage and frequency at the outlet match the
specifications on the pump motor decal. Check the ON-OFF switch to
be sure it is in the OFF position before you plug the pump into an
outlet. Check to be sure the gas ballast valve is closed. Remove and
discard the exhaust plug from the end of the pump’s handle.
2. The pump is shipped without oil in the reservoir. Before starting the
pump, fill it with oil. Remove the OIL FILL cap (black plastic plug
directly in front of the handle), and add oil until oil just shows in the
bottom of the sight glass. Approximate oil capacity of pump:
13 ounces.
3. Replace the OIL FILL cap, and remove the cap from one of the inlet
ports. Turn the Iso-Valve to OPEN. Turn the motor switch to ON.
When the pump runs smoothly, turn the Iso-Valve to CLOSED and
replace the cap on the inlet port. This may take from two to 30
seconds depending on the ambient temperature. After the pump runs
for approximately one minute, check the sight glass for proper oil
level — oil should be even with the sight glass OIL LEVEL line. Add
oil if necessary.
NOTE: When the pump is running, the oil level should be even with the
line on the sight glass. Underfilling will result in poor vacuum perform-
ance. Overfilling can result in oil blowing from the exhaust.
