    5.0 Installation HANDLING AND UNPACKING AirSep Corporation ships the oxygen generator on a wooden skid along with the filter assembly. In the AS-Z series models, vent silencer assembly is also shipped apart from the oxygen generator and filter assembly. The oxygen receiver, if supplied, is also shipped on a separate skid.

  • Page 34: Pre-Installation Guidelines

    Appendix of this instruction manual; however, use of such feed air may require modification of the oxygen generator at the AirSep Corporation factory to ensure the product oxygen meets the specifications. Consult your sales representative to determine whether your oxygen generator requires modifications for your application.

  • Page 35: Installation Instructions

    Airsep oxygen generators are intended to be secured to the floor. Failure to do so can result in the unit tipping over. An example of securing to the floor would be bolting the unit down.
