3. Setup and Installation
Installation of the Amerec 9202-118 Contactor Box requires electrical expertise. It is strongly recommended that a licensed electrician performs the installation to ensure safety and compliance with all applicable codes.

Image Description: This image displays the Amerec 9202-118 Contactor Box. It is a square-shaped electrical enclosure, primarily black or dark gray in color, with a slightly textured finish. The top surface features a label with technical information and warnings. Multiple circular knockouts for electrical conduit are visible on the sides of the box, indicating points for wiring entry. The overall appearance is robust and industrial, typical of electrical control equipment.
3.2 Electrical Connections
The contactor box is designed for 240V, single-phase electrical systems. It serves as an intermediary between the SaunaLogic2.0 control unit and the sauna heater.
- Power Supply: Connect the main 240V/1-Phase power supply to the designated terminals within the contactor box.
- Heater Connection: Connect the sauna heater's power leads to the output terminals of the contactor box.
- Control Signal: Connect the control signal wires from the SaunaLogic2.0 control unit to the low-voltage input terminals of the contactor box. This signal activates the contactor to supply power to the heater.
- Grounding: Ensure all components are properly grounded according to local electrical codes.
WARNING: Incorrect wiring can lead to severe injury, fire, or damage to equipment. Consult the detailed wiring diagram provided with your specific sauna heater and SaunaLogic2.0 control system, and always have a qualified electrician perform these connections.
4. Operation
The Amerec 9202-118 Contactor Box operates in conjunction with the Amerec SaunaLogic2.0 control system. It does not have user-operable controls directly on the unit.
- When the SaunaLogic2.0 control unit initiates a heating cycle, it sends a low-voltage signal to the contactor box.
- Upon receiving this signal, the contactor within the box closes, allowing the 240V/1-Phase power to flow from the main supply to the sauna heater.
- The heater then begins to warm the sauna cabin.
- When the SaunaLogic2.0 control unit terminates the heating cycle (either manually or automatically upon reaching the set temperature), it removes the signal to the contactor box.
- The contactor opens, interrupting the power supply to the heater and turning it off.
Refer to your SaunaLogic2.0 control manual for detailed instructions on setting temperature, time, and other sauna functions.
5. Maintenance
The Amerec 9202-118 Contactor Box is designed for minimal maintenance. However, periodic inspection by a qualified technician is recommended to ensure continued safe and efficient operation.
- Visual Inspection: Periodically check the exterior of the box for any signs of physical damage, corrosion, or overheating (discoloration).
- Cleanliness: Ensure the area around the contactor box is free from dust, debris, and obstructions that could impede ventilation.
- Electrical Connections: A qualified electrician should periodically inspect all electrical connections for tightness and integrity. Loose connections can lead to overheating and potential hazards.
- Internal Components: Only a qualified technician should open the contactor box for internal inspection or service.
CAUTION: Always disconnect power to the unit at the main circuit breaker before any inspection or maintenance work.
