System Installation and Service Instructions
Page 13
Electrical shock hazard - Disconnect
all electrical power before servicing
the Generator. All wiring should be
installed by a licensed electrical
contractor in accordance with local
and national codes.
The Generator is designed for
hookup with copper wire only
User Shock Hazard! Installer must
maintain control wiring segregation.
All control wiring must be restrained
in the "Control Area" designated in
Diagrams 26 & 27.
Protect the AG cable per local
codes if it is routed in:
Areas exposed to weather;
Chemical or hazardous
atmospheres; Areas that may exceed
their temperature ratings or... if
routed adjacent to wires with
voltage above 240V.

WARNING
or more depending on its power rating. It’s normal for
the flow of steam out the steam head to slow for up
to 10 seconds each time the unit calls for water.
7. The unit will shut down automatically in 30 min-
utes if the R30K or K30 Control is used, or up to 60
minutes if the K60 or KT60 Control is used. When the
time runs out the steam will stop and there should not
be any water flow. The control should not be lit.
8. If the unit does not operate as described above,
refer to SECTION 8: TROUBLESHOOTING GUIDE.
THE UNIT IS NOW READY FOR OPERATION.
1. Assure power and water are on.
2. Press the ON/OFF. The control should light-up.
3. Allow 10 minutes for the steam to start.
4. Once the steam starts, press the ON/OFF. The
steam should stop; there shouldn't be any water flow.
The control should not be lit-up.
5. Press the ON/OFF. The control should light up.
6. Within one minute the unit should again produce
steam. It should call for water once every two minutes
SECTION 6: OPERATIONAL TEST
1. ELECTRICAL ROUGH-IN
Size wire for the Generator as indicated by the Elec-
trical Information Chart on page 12. Use correct size
and type to meet electrical codes. Leave 4 feet of
slack wire at Generator location for finish hookup.
Connect the Generator to a dedicated circuit breaker.
A GFCI device is not required by UL. One may be
installed if required by local codes or the owner. A
GFCI may nuisance trip due to heater element aging.
2. ELECTRICAL FINISH
Materials (locally available):
- 3/4" Strain relief for supply wire.
- Circuit breaker per Electrical Information Chart.
a. Route the copper supply wire with appropriate
strain relief through the hole marked POWER ENTRY.
b. Connect the supply wires to the terminal block
marked L1 and L2.
c. Connect the ground wire to the ground lug (green
screw on junction compartment wall).
3. INSTALL SLAVE CONTROL CABLE
a. Route one end of the slave control cable through
the Generator hole marked "Control Wiring Entry".
Use the strain relief provided. Plug the slave control
cable into the connector J1 on the slave PCA. See
Diagram 26.
b. Connect the other end of the slave control cable to
the Master Generator. See Diagram 27.
