Pre-Installation
• Proper electrical supply 240V: See rating label on Steam Generator and Chart on page 13. Determine proper size of wire, voltage, amperage, and
phase for the Steam Generator. 90°C copper wire is required for generator connection.
• In-line fuse/circuit breaker required: Fuse/circuit breaker to be installed must be sized in accordance with chart on back page. Do NOT install a GFI
(Ground Fault Interrupter) to this equipment (per article 210-8 in the National Electric Code).
• Route power supply cable to the location where the Steam Generator will be installed (before walls are closed).
Electrical Rough-in
• Route appropriate power cable to the location the Steam Generator will be installed. If receptacle is desired, mount the box for the receptacle near
the location of the Steam Generator.
NOTE: The plug and receptacle require a rating of no less than 250V and proper amperage. Refer to chart on page 13 for amperage rating. After the
walls are complete, the Steam Generator and Control can be wired.
Steam Generator Electrical Installation
All power to the Steam Generator must be turned off during installation.
• Remove the two screws holding the electrical access cover and remove cover.
• Locate the supply line knockout. Mount proper strain relief into knockout hole.
• Strip back power cable's outer insulation jacket eight inches and insert into Steam Generator. Strip back insulation ½" from the three (3) incoming
wires (two power and one ground).
• Connect incoming ground wire to fuse block and ground terminal.
Be sure the ground wire does not come in contact with a live electrical
part.
• Connect incoming power to terminals labeled "L1" and "L2" (see Figure 2).
• The steam generator is ready for operation once the installation of the controls is completed.
Optional Auto Drain Valve Connection
• Open knockout for Auto Drain Valve conduit connection.
• Route flexible conduit from valve to knockout and secure.
• Connect two wires from valve to the J6 drain connection on the circuit board (see wiring diagram).
