It is important to place the tub on an even surface that can bear the whole weight of the tub. The foundation can be evened out with chips or it can be cast of concrete. We recommend placing some boards or planks on top of the base because when the bottom of the tub is clearly in the air, it airs well and dries. It is also important to ensure that the tub is not covered by grass or hay, as it will prevent the wood from breathing and will cause rotting. When placing the hot tub consider possible places to drain water to. If needed you can lead off the water with an outlet hose. Hot tub’s outlet is located under the hot tub near heater and the outlet’s inner diameter is 50 mm. Take fire safety in consideration when placing the hot tub. Always ensure that the chimney is located away from flammable materials. Remember to check the distance both sideways and vertically to avoid the risk of fire. Note that the discharge valve should always be left open in an empty tub so that water gathered into the tub can run out. During wintertime do not leave the water unattended, in case there is a risk of sub-zero temperatures. You can either drain the water out of the tub or maintain a sufficient heat. The bottom plugs and exhaust valves need to be left open so that any water collected to the tub will discharge. Before lighting up hot tub’s heater always remember to check water level inside of the tub. The heater must not be lit when the tub is empty or the water level is below minimum fill limit. You must not start emptying the tub before the fire and embers have burnt out completely. The minimum fill limit is marked on the heater and in the instructions. In order to keep the hot tub, clean you can buy a model-specific cover. You can also take care of the cleanliness and hygiene of the tub by washing and drying it carefully and often. Washing can be done, for example, with Kirami Biowash. Kirami sells chemicals that can be used for keeping the water clean. When using chemicals, the pH of the water should always be monitored and kept in the given limits, i.e. 7.0-7.6. The diameter of the chimney is 150mm and its lenght is 2m.
