Health and Safety:

  • Your safety is important, so we urge you to take the following precautions when using this product.  We are NOT responsible for injury or damage caused by misuse.
  • Always use eye protection and appropriate thermal gloves during use.
  • Do not heat flammable materials or materials that may also outgas corrosive compounds.
  • Products containing electrical components should not be stored around corrosive chemicals or moist environments that could damage the hardware.
  • Always close the VACUUM VALVE FIRST before turning off the vacuum pump.  Not doing so could result in oil being pulled back from the pump into the chamber/oven.
  • Avoid corrosive chemicals when cleaning the gasket or chamber.
  • Do NOT vacuum flammable gasses.
  • Vacuum chambers are 100% tested prior to shipping and are rated to sustain a vacuum losing no more than 2.5inHg over a 24 hour period.
  • When evacuation exceeds 5 minutes, these solvents begin to vaporize and then re-condense in the vacuum pump reservoir.  Once enough solvent re-condenses in the pump, displacing the oil the plastic internal components may begin to warp, melt or seize.
  • The use of a Cold Trap will condense the vapours prior to making their way to the vacuum pump -- preventing pump damage due to excessive use.
  • Minwax Wood Hardener™ is not to be used with any vacuum pumps EVER.  A seized motor will result within the very first use.
  • To prevent these issues from happening to your process, change the Pump Oil after each vacuum pump use, even if the use time is only 5 minutes.
