Install Instructions
PRIOR TO OPERATION:
The hilmor Vacuum Pump motor is designed for 120
volts, plus or minus 10%. The single voltage motor is fully
connected and ready for operation.
1. Check the voltage at the outlet to ensure it matches the specifications on
the hilmor Vacuum Pump motor plate. Ensure that the power switch is in
the o position before connecting the pump to a power source. The light
in the power switch will remain on if the pump is connected to a power
source, even though the pump is o.
2. Fill the oil reservoir with hilmor Vacuum Pump Oil by removing the oil fill
cap and adding oil until it has reached the level between Min and Max on
the sight glass. Make sure to fill with oil before switching the pump on.
Oil capacity can be found on the hilmor Vacuum Pump motor plate and in
the Technical Specifications.
3. Replace the oil fill cap and remove an unused cap on the inlet tree fitting.
Make vacuum connections. Then turn the power switch to the on position.
4. Close the cap on the unused inlet tree fitting after a few seconds and open
the gas ballast on the side of the pump.
5. After the pump is running smoothly, close the gas ballast. The hilmor Vacuum
Pump will typically run smoothly after pulling to approximately 3,000 microns,
depending on the ambient temperature.
6. Double-check the oil level and top o if necessary.

SHUT-OFF:
1. Blank o at the manifold or hilmor Valve Core Removal Tool by moving the
handle to the o position.
2. Open an unused inlet tree fitting and continue to run the hilmor Vacuum
Pump for a few seconds.
3. Turn the power switch to the o position and replace the cap on the unused
inlet tree fitting.
4. Remove the hose from the inlet tree fitting.
5. Replace brass caps on the inlet tree fitting to prevent contamination.
TO PULL THE FASTEST VACUUM, FOLLOW THE TIPS BELOW:
• Connect the hilmor Vacuum Pump directly to the system. Using a manifold
slows the vacuum process.
• Use the hilmor Valve Core Removal Tool at the system port to remove the
Schrader® valve.* This allows for less restricted flow.

• Use a large-diameter (3/8" or 1/2") evacuation hose. This allows for a faster
flow rate.
• Use the shortest hose possible to achieve greater eciency.
Long hoses slow the vacuum process by creating a longer flow path.
• Use hilmor Stainless Steel Evacuation Hoses for as many connections
as possible. Permeation and outgassing from rubber hoses will slow down
your vacuum.
• Connect a vacuum gauge to the side port on the hilmor Valve Core
Removal Tool to measure vacuum. Placing the vacuum gauge close to the
pump will give a less accurate pressure reading of the system.
