AW Generator - Wiring Instructions

 

1. ELECTRICAL CONNECTION

Size wire for the generator as required by local or national codes. See the electrical information on page 13 for further information. Use copper wire only. Leave 1,2 m of slack wire at generator location for finish hookup. Connect the generator to a dedicated circuit breaker. A GFI device is usually not required by safety agencies. One may be installed if required by local codes or the owner. A GFI device will tend to nuisance trip due to heater element aging.

  1. Route the copper supply wire with appropriate strain relief through the hole marked POWER ENTRY.
  2. Connect the supply wires to the power terminal block as indicated on the wire diagram for your voltage and phase. This may require moving factory installed jumper. Do not change the steam generator’s internal jumpers or wiring. Only the supply wiring side of the terminal blocks require configuration by the installer.
  3. Connect the Earth wire to the copper Earth ground lug.
  4. Cover the supply wires inside the steamer with a protective mesh or similar material to protect them from water valve heating.

2. ELECTRICAL INFORMATION

The AW Steam generators are supplied for connection in single up to 240V or 3 phase – ~3N – up to 415V.

All Units are factory wired for single phase installation. The installer may change the input to three phase or three phase with Neutral during initial installation (see the wiring diagrams on page 18).

If model AW 14 in connected for single phase, two separate supply lines will be required.

Notes

  • Use only copper wire rated 600V~ and 75°C minimum
  • All models require Earth ground
  • All line voltage must be more than 195V~ while the steamer is heating
  • Generators must be connected to a means for disconnecting all supply voltages
  • All AW14 single phase generators require two mains supplies
  • We recommend ceilings height be 2,4m max. Higher ceilings may cause sitting area to be uncomfortably cool.
