3 Person Outdoor Traditional Sauna: Manual & Guides

The 3 Person and 4-5 Person Outdoor Traditional Saunas share one manual. It covers assembly step by step, the steps for your electrician, electrical requirements, the 12V LED driver, the Harvia wiring diagrams, the Harvia Fenix control panel, WiFi and MyHarvia 2 app setup, how to use and care for your sauna, and your warranty. Page 8 shows our recommended silicone for sealing the outside joints: Selleys 310g Black Roof and Gutter Silicone, available at Bunnings.

Installing the sauna requires a minimum of two people.

Your sauna is fitted with a genuine Harvia The Wall 6kW electric heater (model SW60E) in black steel, with 20kg of Harvia stones. The heater is controlled from the Harvia Fenix control panel. The Harvia manual covers stone placement, safety distances, installation and resetting the overheat protector.

The piling of the sauna stones has a great effect on both the safety and the heating capability of the heater, especially for electric heaters. Always check the right heater stone size and amount from the manual included with the heater. Smaller 5 to 10 cm diameter stones are usually used in electric heaters as they fit well between heating elements. Smaller stone sizes are also used on the top layer of woodburning heaters as they create more surfaces for steam generation. Larger 10 to 15 cm diameter stones are used in woodburning heaters and also in selected Harvia electric heaters with larger stone capacity.

Start the stone piling by washing off the dust from the stones before placing them into the heater. Be aware that the type and the shape of the heater affect the piling structure of the stones. Your best guide for doing this properly for your selected heater is to follow the instructions included in the heater manual. Here are a few important tips for piling sauna heater stones for all Harvia heater types.

• Do not drop stones into the heater
• Arrange the stones evenly and loosely to ensure air can flow between them
• Do not form a high pile of stones on top of the heater
• Do not place stones on top of the heater frame
• Place elongated stones vertically in the heater

Also note for electric heaters:

• Do not wedge stones between the heating elements
• Pile the stones so that they support each other instead of resting heavily on the heating elements
• Support the heating elements with stones so they don't bend

New stones may give the sauna a natural stone scent during the first heating. After piling the stones, we recommend heating the sauna and pouring enough water to douse all the stones. This will help remove any unwanted scent from the stones after the initial use.

Your sauna is controlled from the Harvia Fenix WiFi touch panel, mounted on the back wall under the backrest so it is within reach while seated, or from the MyHarvia 2 app on your phone.

• Touch panel: choose a preset (Mild, Cozy or Hot), set the temperature and session time, set a ready time, and switch the lights.
• MyHarvia 2 app: check the temperature and heating time from your phone and get a notification when your sauna is ready. Starting the sauna from your phone needs Harvia's Control upgrade, a one-time fee with a 3 month free trial on new panels.
• Temperature: up to 110°C.
• Heat-up time: approximately 30 to 45 minutes.
• Session length: 1 to 6 hours of operation.
• WiFi: the panel connects to a 2.4 GHz WiFi network. Keeping it connected also keeps its software up to date.

Pages 18 to 21 of the Nordhaus manual explain the panel, WiFi and app setup step by step.

All electrical work must be completed by a licensed electrician. Please refer to the Nordhaus Outdoor Traditional Sauna manual above for all electrical and wiring information.
