🧼 2. Preparing Your Hot Tub for Relaxing, Warm Baths

Before enjoying your new hot tub, it is important to give it a thorough cleaning for a fresh and pleasant first experience.

✔️ What You’ll Need:

• Mild cleaner: Use a specially developed cleaner for hot tubs. For occasional use, a mild, non-abrasive bathtub cleaner may also be used. Avoid strong chemicals such as acetone, thinner, or varnish remover, as they can damage the surface.
• Soft cloths or sponges: Use soft materials to gently clean the interior without scratching the acrylic or fiberglass surface.

🪣 Cleaning Steps:

1. Rinse thoroughly: Rinse the entire interior of the hot tub with clean water to remove dust and dirt before applying any cleaner.
2. Apply cleaner: Follow the manufacturer’s instructions and apply with a soft cloth or sponge. Pay special attention to jets and headrests where dirt can accumulate.
3. Rinse and wipe: Wipe the surface carefully, rinsing the cloth often. Finish by rinsing the tub thoroughly to remove any cleaning residues.

🚰 Filling Your Hot Tub:

1. Fill with fresh water: Once cleaned, fill the tub with tap water as instructed by the manufacturer. Leave 15–20 cm (6–8 inches) free at the top to allow for water displacement when in use.
2. Check the water level: Before heating, ensure the water level is within the recommended range marked inside the tub.

🔥 3. Heating Your Hot Tub with the Integrated Stove

Once your hot tub is filled with clean water and 15–20 cm (6–8 inches) of space is left at the top, you are ready to light the stove and enjoy a relaxing bath. Follow these steps:

✔️ How to Light the Stove Safely:

1. Use only approved fuel: Always follow the manufacturer’s recommendations. Avoid coal, fresh wood, or wet/damp firewood, as they can be unsafe or ineffective.
2. Start gently: Build a small fire with dry kindling and paper. Once the flame is stable, gradually add larger pieces of dry firewood.
3. Control the heat: Use the damper at the bottom of the stove door to regulate airflow and thus control both the fire intensity and water temperature.

🌡️ Important Temperature Rules:

• Never exceed 45°C (113°F): Fiberglass tubs can be damaged by excessive heat. Keep the water at a maximum of 45°C – ideally around 37°C (98.6°F).
• Do not overfill the stove: Fill the stove no more than two-thirds of its height to avoid overheating and damage to the stove door.

⚠️ Safety First:

• Never light the stove without water: The hot tub must always be filled to the correct level before use, otherwise the stove and tub can be seriously damaged.
• Allow the stove to cool before draining: Always let both water and stove cool completely before emptying to prevent heat damage.

💡 Extra Tip:

Consider investing in a hot tub thermometer for precise temperature monitoring.

🔥 4. Heating Your Hot Tub with an External Stove

An external stove is an effective way to heat your hot tub, adding a touch of luxury. Here’s what you should know:

✔️ Preparation and Safety:

• Stable surface: Ensure both the stove and hot tub are placed on a solid, level base. Tilt the stove slightly forward if necessary for better water circulation.
• No modifications: Never add extra filters or change the built-in circulation system of the stove.
• Fill the tub first: Always fill to the recommended level (15–20 cm from the top) before lighting the stove. Running the stove without water can damage both tub and stove.
• Monitor temperature: Use a thermometer to ensure water temperature stays safe — ideally 37°C and never above 45°C.

🔥 How to Light the External Stove:

1. Start small: Use dry kindling and paper to light a small fire, then gradually add larger pieces of dry wood.
2. Control airflow: Adjust the damper on the stove door to regulate the flame and water temperature.
3. Avoid overloading: Do not overfill the stove with wood, as this may lead to excessive heat and damage the stove door.

❄️ Additional Considerations:

• Winter care: In freezing conditions, drain the hot tub completely when not in use. Alternatively, use an electric heater to keep the water above freezing.
• Correct hose connections: Ensure hoses are properly connected: the top hose should go upward, and the bottom hose connects directly to the tub. Follow the illustration below:

By following these guidelines and your user manual, you can heat your hot tub safely and efficiently with an external stove — and enjoy a relaxing experience.

⚡ 5. Electrical Safety and Your Hot Tub

Your hot tub may include electrical components such as pumps, filters, lighting, and electric heaters. To ensure correct operation and safety, all electrical connections must be done properly.

⚠️ Important Note:

Never attempt to install or connect electrical components for your hot tub yourself. Always hire a certified electrician experienced with hot tubs and familiar with regulations.

🔧 The Electrician’s Tasks:

• Connect the hot tub’s electrical system to a dedicated circuit with the correct breaker size.
• Install a residual-current device (RCD) for protection against electric shock.
• Ensure all connections comply with local building codes and safety standards.

✅ Additional Safety Rules:

• Never use extension cords with your hot tub.
• Always keep electrical components dry and away from water.
• If issues occur, switch off the power immediately and contact a licensed electrician.

By choosing professional installation and following these precautions, you can enjoy your hot tub safely.
