Vacuum Pumps

1. Equipment Inspection - Before using your vacuum pump, be sure to check the entire product for damage including cracks, dents, or any other kind of visible blemishes that may render the item unsafe. Do not use the pump if any such damage is visible. Always be sure to check the pump's oil level, and add or replace oil regularly. Be sure that all connections are air-tight with no leaks.

2. Proper Use - Vacuum pumps will exhaust fumes, smoke, and spew oil; this is normal and part of how the pump operates. Always use vacuum pumps in well ventilated areas, or use proper exhaust filters and tubing to redirect exhaust outdoors. Vacuum pumps are not meant to run continuously and doing so will void your warranty on the pump. If you need to run the pump continuously, be sure to have a cold-trap filter inline between the pump and oven/chamber.

3. Pay Attention - Never leave a vacuum pump running unattended. Keep equipment away from children and pets. Be sure your chamber/oven is able to accept the amount of vacuum applied by your pump. Vacuum implosions can be fatal.
