page 3 of 8 Safety information! General information ☞ Read this manual carefully before installing or operating the equipment. Observe the instructions contained in this manual. Comply with technical data and notes on use and operation. ☞ Do not use any damaged equipment. • NOTICE Prior to every use: Check the cold trap for damage. The glass surfaces must be free from damage, notches, cracks or scrapers. Remove the product from its packing-box.
page 4 of 8 Operating conditions of cold trap GKF 1000i ➨ The cold trap GKF 1000i is not suitable to condensate - unstable substances, - self inflammable substances, - substances which are inflammable without air and - explosive substances. Safety during operation ➨ Adopt suitable measures to prevent the release of dangerous, toxic, explosive, corrosive, noxious or polluting fluids when draining condensate. ➨ Adopt suitable measures to prevent the formation of explosive or flammable mixtures.

page 7 of 8 Use and operation Installing in a vacuum system PC 3 (1) (2) ➨ Remove the transportation safety device (foam insert) in the cove of the cold trap. ➨ Grease the ground joints prior to use with vacuum grease. ➨ Assemble the cold trap to a base plate or fixate at a stand mounting. ➨ Connect the cold trap to the vacuum pump and the recipient. ☞ Prevent mechanical stress at the connection due to tensile force or vibrations. ➨ Close the condensate drain valve.
page 8 of 8 Remove the cold trap from the vacuum installation to drain the coolant if necessary. Maintenance and cleaning - The cold trap is maintenance-free. Clean the metal cover of the cold trap using water only. Clean the coolant chamber and the condensate chamber using water or solvent. Ensure compatibility of the wetted parts. ☞ Comply with applicable regulations when disposing of solvents.
