Check the power supply before installing your unit. Single Phase connection, a 220-240V
supplied is required. Use two-wire supply source and equipment grounding wire of single
phase connection.
The installation must include switch for all pole disconnection. Circuit breaker with 3mm
control gap is recommended.
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.
