Wiring Instructions

 

1. T100 CONTROL CABLE ROUGH IN
The low voltage control can be mounted up to 25 feet from the generator either inside or outside the steam room. A 25’ shielded 8 conductor cable (provided) is required for connecting the T100 control to the steam generator. String the 25’ cable from the control location through 1/2” holes in the wall studs or ceiling joists to the generator. Note: Do not staple through or damage cable. Use factory supplied cables only.

ELECTRICAL SHOCK HAZARD! Hazardous voltage is exposed inside the steam generator. Shut off all power to the generator before servicing. Supply electrical power through copper wire rated 75C minimum.

2. TEMPERATURE SENSOR CABLE ROUGH-IN
It is recommended that the sensor be mounted in the steam room 6” from the ceiling, but not directly over the steam dispersion head or more than 7 feet above the fl oor. String the sensor cable from the sensor location through 1/2” holes in the wall studs or ceiling joists to the generator location. Leave 12” of slack at the sensor location. Note: Do not staple through or damage cable. Use factory supplied cables only.

A GFI device is not required by UL or NEC. 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. To reduce the risk of electrical interference from other devices, use only a shielded cable to connect the T100 control to the steam generator.

3. ELECTRICAL ROUGH-IN
Size wire for each generator as indicated by the Electrical Information Chart on page 9. Use correct size and type to meet electrical codes. Leave 4 feet of slack wire at generator location to fi nish hookup. Connect the generator to a dedicated circuit breaker.

4. ELECTRICAL FINISH
At the generator, route the copper supply wire with a 3/8” strain relief through the hole marked POWER ENTRY. Connect the supply wires to terminals marked L1 and L2 (and L3 for three phase). Connect the supply ground to the ground lug (green screw). Refer to the wire diagrams at the end of this document for your model.
Note: AT12 and AT14 single phase units require two separate supplies. Refer to the electrical chart and wire diagram when connecting these units.

5. INSTALL T100 CONTROL
The low voltage control can be mounted directly to a fi nished wall either inside or outside the steam room. Using the supplied template, cut a hole in the fi nished wall where the control is to be mounted (the control cable should already be roughed-in to this location). Locate the control cable and plug it into the back of the control housing. See diagram 11. Run a bead of 100% silicone caulk around the perimeter on the back of the control housing. Insert the T100 into the fi nished wall, center the control and tape the control against the finished wall while the silicone hardens.

6. INSTALL THE TEMPERATURE SENSOR
The temperature sensor should be mounted 6” below the ceiling, inside the steam room, but not directly over the steam dispersion head or more than 7 feet above the fl oor. Using a 7/8” hole saw, drill a hole in the fi nished wall where the sensor is to be mounted (the sensor cable should already be roughed-in to this location). Locate the sensor cable, pull it out through the hole and plug it into the temperature sensor. It is best to tape the sensor and cable connection together to avoid disconnection inside the wall. Apply silicone caulk as shown in diagram 8 and insert the sensor in the hole.

Make sure that the sensor probe is pointing down once installed. Tape the sensor in Place while the silicone hardens. Route the generator end of the sensor cable through the generator hole marked CONTROL WIRING ENTRY using the control cable strain relief. Plug the sensor cable into the RM TEMP connector on the printed circuit board assembly. See diagram 12.

7. WIRING THE GENERATOR CONTROL CABLES
Choose one generator to be your “Master” unit. This generator will control the other one or two “slave” generators in the system. If the generators are not the same size (kW), the largest wattage generator should be the master.

At the Master generator: Route the generator end of the control cable through the generator hole marked CONTROL WIRING ENTRY using the strain relief provided.

Plug the control cable into the T100 metal shielded connector on the printed circuit board assembly. See diagram 12. Connect a shielded control cable to the Master generator’s OUT1 jack and route this cable out the Master’s CONTROL WIRING ENTRY and into the fi rst slave generator though its CONTROL WIRING ENTRY hole. Connect this cable to the slave’s T100 jack. If a second slave generator is to be used, route another control cable in the same manner from the Master’s OUT2 jack to the slave’s T100 jack. Note: If additional room is needed at the Master generator for routing the slave cables, a knock out is provided next to the CONTROL WIRING hole. Secure all cables.
