    steam outlet The steam must move in a continuous flow to the steam room. Do not install valves on the steam line. Use insulated, rated 120ºC or higher, brass pipe or copper tubing for steam line to connect to the steam head as permitted by codes (see table below). Slope the steam line height by 20mm per meter towards the steam head to avoid trapping of the condensate and eliminate steam trap that blocks the flow of the steam.

  • Page 14: Drain

    Use two-wire supply source and equipment grounding wire of single phase connection. A 90ºC / 600V (HO7RN-F) rated insulated copper wire is required for SAWO steam generators. Check size of wires in Ampere Chart in accordance with the National Electrical Code and local electrical code.
