Wiring Instructions for Steam Generator AT and 3T


IMPORTANT! Regular maintenance will help your steamer work properly for a long time. Check for leaks, loose or damaged wires, signs of corrosion and calcium build up in the tank on the level probe. This is particularly important in areas with high calcium levels and other water quality problems. Calcium build can cause poor steamer performance and damage the heating elements!

WARNING: 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.

1.T100 CONTROL CABLE ROUGH-IN The low voltage controls can be mounted directly to a fi nished wall up to 7.6 meters from the generator and either inside or outside the steam room. A 7,6 m shielded 8 conductor cable (provided) is required for connecting the T100 control to the steam generator. String the 6,8 m cable from the control location through 13 mm holes in the wall studs or ceiling joists to the generator. Note: Do not staple through or damage cable. Use factory supplied cables only.

A mounting template is included at the end of this document. Using the supplied template, cut a hole in the fi nished wall where the control is to be mounted and pull the cable end out through the mounting hole.

2. TEMPERATURE SENSOR CABLE ROUGH-IN It is recommended that the sensor be mounted in the steam room 150 mm from the ceiling, but not directly over the steam dispersion head or more than 2,1 m above the fl oor. Using a 35 mm hole saw, drill a hole in the fi nished wall where the sensor is to be mounted. String the sensor cable from the sensor location through 13 mm holes in the wall studs or ceiling joists to the generator location. Leave 305 mm of slack at the sensor location. Note: Do not staple through or damage cable. Use factory supplied cables only.

3. ELECTRICAL ROUGH-IN Size wire for the generator as indicated by the Electrical Information Chart on page 8. 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. A GFI device is generally not required. 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. 

4. ELECTRICAL FINISH 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. • Connect the ground to the ground lug.

5. INSTALL T100 CONTROL (The control cable should already be roughed-in to this location according to step 1, above.). Locate the control cable and plug it into the cable on the back of the control housing. See diagram 8. Run a bead of 100% silicone caulk around the perimeter on the back of the control housing. and insert the T100 into the fi nished wall, center the control and tape the control against the fi nished wall while the silicone hardens.

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 10.

6. INSTALL TEMPERATURE SENSOR (The temperature sensor should already be roughed-in to this location according to step 2 in this section.). Locate the sensor cable, pull it out through the hole and plug it into the emperature 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 9 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 10.
