This document provides a comprehensive guide for the installation, start-up, use, and maintenance of a hot tub. It includes essential safety measures, technical specifications, and troubleshooting information.
The hot tub is designed for bathing, offering a combination of bathing and massage. It features a pump-driven closed water loop that produces a relaxing massage on a person's body. The device is equipped with various functions including filling, draining, filtration, massage, chromotherapy, and a smart winter mode (SWM). It also incorporates an ECONO mode for energy efficiency.
The hot tub requires a suitable electrical installation. It must be connected to a domestic power line and protected by a highly sensitive residual-current device (RCD) of 30 mA. The system's electrical input must always be protected by an RCD. The maximum values that appear on the electrical panel must never be exceeded. The manufacturer reserves the right to change part of the designs or specifications without prior notice or any liability on its part.
Power Requirements:
Nominal Section of the Cable in mm² (KW required):
| Distance | 2,1 | 2,5 | 2,8 | 3,2 | 3,5 | 4,6 | 5,3 | 6,2 | 7 | 7,9 | 8,8 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 6-11 m | 2,5 | 2,5 | 2,5 | 4 | 4 | 6 | 10 | 10 | 10 | 10 | 10 |
| 11-15 m | 2,5 | 2,5 | 4 | 4 | 6 | 6 | 10 | 10 | 10 | 10 | 16 |
| 15-20 m | 4 | 4 | 6 | 6 | 6 | 10 | 10 | 10 | 16 | 16 | 16 |
The cable's cross-sectional area will increase proportionally for greater distances. The electrical layout must be performed by duly qualified persons and always comply with the current regulations in each country.
The hot tub requires both hot and cold water outlets to be installed for automatic filling. A water seal (siphon) is necessary to be installed in the drain area. The thermostatic valve receives cold water from the drinking water supply and hot water from the domestic hot water (DHW) system. The desired temperature at which the hot tub is filled is set via the waterfall (orange arrows). The water seal (siphon) is not supplied with the hot tub.
The temperature of the water in the loop must be between 34°C and 37°C. This is achieved using an electric heat exchanger or an external heater. The maximum temperature that it can withstand is 60°C. The recommended ideal temperature is 35-36°C. The hot tub should not be left outdoors with water inside and disconnected from the power at temperatures below 0°C. The water may freeze in the pipes and damage the hot tub.
The hot tub must be installed on a suitable, flat, and level surface that can bear its weight when in use (full of water, plus the weight of the bathers). Do not install it on a curved surface or on top of blocks that concentrate the weight at specific points. A suitably sized drain must be provided to allow the full volume of water to drain away. The hot tub's frame should never be fixed to the ground. The hot tub contracts and expands due to temperature changes.
With the main residual-current device in the OFF position, clean the hot tub's shell to prevent any particles from the installation work being absorbed into the components/loops or clogging them. Then, switch the residual-current device into the ON position, open the stopcocks, and, on the control panel, start filling by holding down the fill solenoid valve button for 3 seconds. This opens the fill solenoid valve. Adjust the thermostatic valve to set the desired inlet water temperature.
The control panel features various commands:
The hot tub is equipped with L1 and L2 sensors. L1 is considered safe provided that the sensor detects water for at least 3 consecutive seconds. If water is not detected for that length of time, it remains off, thus activating the automatic filling procedure. L2 is the maximum level sensor. When the water reaches the maximum level sensor (L2) and continues to be detected for 10 consecutive seconds, it disables automatic filling. If the water level is below the L2 sensor, automatic filling is activated.
This function prevents water-carrying parts from freezing. It starts automatically if the temperature detected by the water probe is ≤ 7°C. If smart winter mode is activated, filtration is stopped and then resumed 1 minute after SWM ends.
Every 30 minutes, the filtration pump is activated for 30 seconds to read the temperature. The first time either the "-" or "+" button is pressed, the control panel displays the current set temperature and both buttons light up blue; every time you press the buttons after that, the value will increase or decrease accordingly. If the "-" or "+" buttons are not pressed for 6 seconds, or a different button is pressed, the screen shows the temperature again and both buttons light up white again.
Regular maintenance ensures the long service life of your hot tub and its components. This includes cleaning the acrylic shell, water maintenance, and filter maintenance.
Use common general purpose cleaners. For normal care and cleaning, use a soft cloth or sponge with a little soap and water. Rinse well and dry with a clean, dry cloth. Do not use abrasive cleaners. Do not allow the acrylic surface to come into contact with ketones, esters such as acetone, acetates (such as nail varnish remover, nail varnish or dry cleaning substances) or any organic solvent with chlorine, varnishes, petrol, aromatic solvents, etc. Remove dust, mud and dry dirt with a soft damp cloth.
Water maintenance is crucial and depends on the mineral content of the water used, how often the hot tub is used, and the number of people who use it. Key points for water maintenance include water filtration, chemical analysis and pH control, and water disinfection.
Adjusting the pH: A pH value between 7.2 ppm and 7.6 ppm is recommended. pH level measures acidity and alkalinity. Values above 7 ppm are alkaline; below 7 ppm they are acidic. It is extremely important to maintain a correct pH level to ensure that the disinfectant works properly and to avoid any corrosion or scaling in the hot tub.
Water Disinfection: Disinfecting the water is vitally important to destroy algae, bacteria and organisms that can grow in the water. Bromine tablets are the most suitable water disinfectant for your hot tub. This product is placed in the pre-filter to gradually dissolve.
Ozone Generator: Ozone, O3, is an oxidising chemical compound that is very effective at disinfecting water. Its main benefits are that it leaves no chemical residues and it is odourless. It works as a disinfectant thanks to its oxidation potential, which eliminates any organic matter that may be in the water.
UV Disinfection: UV-C allow water to be disinfected without using chemicals. When bacteria, viruses and protozoa are exposed to wavelengths between 200-300 nanometres (range C), these waves become a quick and effective germicide, preventing microorganisms from reproducing and contaminating the water.
The filter cartridge should be checked regularly. If there is a build-up of dirt, it will have to be cleaned or replaced. Remember that a clogged filter causes a drop in the water flow rate, which may cause a fault in the hot tub. All hot tubs include a cartridge filter. Check the filter regularly and follow the maintenance instructions that appear below.
Cleaning the Telescopic Filter:
The spotlight maintenance may require the replacement of the lamp. Follow the steps below to replace the lamp:
If you do not use the hot tub during the winter or for very long periods, you must perform the following operations:
