The Nootka Saunas Barrel Sauna Heater Setup Instructions provide a comprehensive guide for installing and troubleshooting Homecraft sauna heaters, specifically the HSH 7.5kW and HSH 9kW models, designed for single-phase installation. This manual emphasizes the importance of professional electrical installation and adherence to local electrical codes.

Function Description:

The Homecraft sauna heaters are designed to provide heat for barrel saunas, creating a therapeutic and relaxing environment. They operate by heating sauna rocks, which then radiate heat into the sauna room. The system includes a digital wall-mount control panel for precise temperature and time adjustments, a temperature sensor for accurate readings, and a relay control box that houses the transformer and relays. The heaters are equipped with a thermal safety switch to prevent overheating, ensuring safe operation.

Important Technical Specifications:

Models: HSH 7.5 and HSH 9
Power Output:
- HSH 7.5: 7500 Watts
- HSH 9: 9000 Watts
Voltage: 240/208 Volts

- HSH 7.5: 31.3/36.1 Amps
- HSH 9: 37.5/43.3 Amps
Circuit Breaker:
- HSH 7.5: 50 Amps (NON GFI)
- HSH 9: 50/60 Amps (NON GFI)
Wire 90° C Copper: 8 AWG for HSH 7.5, 8/6 AWG for HSH 9. The manual specifies 8-2 TECK cable (or equivalent AWCU) for outdoor environments, which is armored and rated for outdoor use, and can be trenched.
Control: Digital (TKE1 for HSH 7.5, TKE2 for HSH 9). The control panel operates on a Class II 24-volt circuit.
Weight: 67 LBS for both models.
Clearance to Ceiling: 42 inches.
Minimum Room Cubic Footage:
- HSH 7.5: 370 cubic feet
- HSH 9: 360 cubic feet
Maximum Room Cubic Footage:
- HSH 7.5: 450 cubic feet
- HSH 9: 300 cubic feet
Minimum Ceiling Height: 78 inches.
Temperature Sensor Wire: 18/2 wire, 12 feet in length, with soldered temperature sensor.
Control/Voltage Wire: 18/4 wire, 12 feet in length.
Junction Box: 884 Junction Box for rear wall, supplied by Nootka Saunas.
Weatherproof Disconnect: Typically required by most jurisdictions, visible and within a certain distance of the sauna.
Heater Guard Rail: Recommended to be made of Western Red Cedar, with a minimum 4-inch clearance on all sides (except one for CHSH heater).

Usage Features:

Digital Control Panel: The electronic digital wall-mount control panel allows for precise adjustment of time and temperature. It features simple operation with gentle finger pressure on square switches.
Temperature and Time Adjustment: Time and temperature can be easily adjusted by pressing the appropriate button for 3 seconds. The maximum allowed time setting is 60 minutes.
Temperature Readouts: The control panel can display temperature in Fahrenheit or Celsius, up to a maximum of 194°F (90°C), as permitted by national code.
Status Display: Touching any button on the control panel will display the current status of the sauna.
Thermal Safety Switch: All Homecraft sauna heaters include a thermal safety switch located in the front of the element box, just below the front shroud, to prevent overheating. If the heater switches off due to an abnormal condition, it can be reset by pressing the safety switch stem in a small hole on the front face of the heater after it has cooled down.
Sauna Rocks: The heater rock basket should be filled with the provided sauna rocks, ensuring proper airflow around them to prevent overheating. The heater should not be operated without the recommended quantity of rocks.
Initial Start-up: After installation, the heater should be turned on high for one hour to "settle" in the heater and rocks. During this time, any protective coating on the elements will burn off, which is normal. It is advised not to enter the sauna room during this initial start-up.
Water Application: Only a sauna bucket and ladle should be used to put water on the sauna rocks; shower heads or water spray equipment should never be installed above a sauna heater.

Maintenance Features:

Cleaning the Control Panel: The control panel can be cleaned with a damp cloth and a mild soap. Harsh cleaners like Windex or ammonia-based cleaners should be avoided.
Temperature Sensor Inspection: In public saunas, the temperature sensor should be visually inspected daily to ensure there are no obstructions and that air flows freely around it. The sensor cover is designed for maximum security against vandalism.
Troubleshooting Guide: The manual includes a detailed troubleshooting checklist for common issues, such as no display on the front wall, no temperature readout, contactor not pulling in, or lack of heat production. This guide recommends using a multimeter for checks and emphasizes that troubleshooting should be performed by a certified electrician.
Resetting Thermal Limit Switch: If the heater frequently trips the safety switch, it may indicate a problem requiring attention from a qualified serviceman or Homecraft directly. The reset button for the thermal limit switch is located at the base of the heater.
Wiring Inspection: The troubleshooting section advises checking the security of all 18AWG wires in the rear wall terminal block and front control panel, as well as inspecting for any punctures or damage to the low voltage wiring during sauna assembly.
Heater Wiring Inspection: If no heat is produced, the heater wiring might be loose or improperly connected. The manual suggests dismounting the heater guard, removing rocks, and flipping the heater to inspect and ensure good connections between L1, L2, and GND.
Access to Relay Control Box: The relay control box can be surface-mounted or flush-mounted in an accessible location (e.g., above a suspended ceiling or behind a removable panel on the outside wall) to facilitate future servicing.
