INITIAL PREPARATION
1. The vacuum pump is shipped without oil in the
reservoir. Remove the exhaust/oil fill cap and add oil
until it can be seen in the middle of the oil sight glass.
Re-secure cap.
2. Connect vacuum pump to the proper voltage power
supply.
3. Remove the 1/4" inlet service port cap, turn on the
vacuum pump. After 15 seconds, replace 1/4 cap back
on inlet port.
4. Re-check vacuum pump oil level. Add or remove oil if
necessary. To achieve good final vacuum levels, the oil
level should be visually seen through sight glass.
CAUTION:DO NOT RUN THIS EQUIPMENT WITH LOW
OR NO OIL. RUNNING THIS EQUIPMENT WITH NO
LUBRICATION WILL CAUSE PREMATURE FAILURE.
VACUUM PUMP IS NOW READY FOR USE.
VACUUM PUMP OPERATION
WARNING:DO NOT operate on systems under pressure.
Damage to the pump may occur.
1. Check the correct power supply outlet to be used.
2. Connect vacuum pump to the proper voltage power
supply.
3. Check oil level in vacuum pump.
4. Connect vacuum pump as shown in Figure - 1.
5. Open manifold valves.
6. Turn vacuum pump power switch ON.
7. Run vacuum pump until final vacuum level is met.
8. Once the final vacuum level is reached, close manifold
valves, turn power switch OFF.
ROUTINE MAINTENANCE
It is recommended to change the vacuum pump
oil after 50 hours of usage. The purity of the oil will
determine the final vacuum level achieved. Always use
the recommended vacuum pump oil. The oil provided
with the pump has been specially blended to maintain
maximum viscosity at normal running temperatures as
well as cold weather starts.
OIL CHANGE PROCEDURES
1. Be sure the pump oil is warmed up. If not warm, turn
vacuum pump ON for 10 minutes.
2. Make sure vacuum pump is not plugged in.
3. Remove the oil drain cap and drain the contaminated
oil into a suitable container. Tilt the vacuum pump
toward the oil drain port.
4. Once all the oil has been drained, re-secure the oil
drain cap back onto the oil drain port.
5. Remove the exhaust/oil fill cap and add oil until it is
seen in the middle of the oil sight glass. Re-secure
exhaust/oil fill cap.
