  • Page 8: Long Term Storage Requirements

    We suggest using the accompanying Long Term Storage Log sheet for recording purposes to validate the appropriate procedures. Prior to start-up, Vilter recommends that a complete system pressure check be performed. Upon verification of the system integrity, a comprehensive evacuation procedure should be completed to ensure a dry system before refriger- ant is introduced.
  • Page 9 Long Term Storage Requirements Remove the condensation drain plugs from those units equipped with them and insert silica-gel into the openings. Insert one-half pound bags of silica-gel (or other desiccant material) into the air inlets and outlets of drip-proof type motors. NOTE: The bags must remain visible, and tagged, so they will be noticed and removed when the unit is prepared for service.
