It is advisable to leave enough space around the hot tub for future service.

We recommend keeping access to at least:

60-80 cm around the technological part of the hot tub.

The most important thing is to access the part where it is located:

• control unit,
• pumps,
• heating,
• filtration,
• ozonator,
• electrical connection.

If the hot tub will be embedded in the terrace or enclosed, it must be prepared service doors or removable panels.

The hot tub should never be built in such a way that the technology cannot be accessed. In the event of a defect, it would then be necessary to dismantle the terrace or cladding.

The hot tub must stand on firm, flat and stable surface.

An ideal background is, for example:

• concrete slab,
• paved terrace,
• paving on a quality base,
• solid foundation ready for heavy loads.

It is important to take into account that a filled hot tub can weigh even more than 1,500-2,500 kg according to model size, water and number of people.

The area must be:

straight, load-bearing, stable and must not sag over time.

We do not recommend placing the hot tub directly on grass, clay, uncompacted gravel or soft ground.

Before delivering the hot tub, it is necessary to verify that it is possible to get the hot tub into place.

We recommend checking:

• goal width,
• sidewalk width,
• stairs,
• passages around the house,
• height differences,
• the possibility of using manipulation techniques.

Hot tubs are large in size and are often shipped on their side. If access is difficult, more people, special handling equipment or a crane may be needed.

Before installation, we recommend ensuring the ability to quickly fill the hot tub.

It is ideal to have nearby:

garden tap / hose / water supply.

The hot tub is usually filled with a garden hose. The closer the water supply is, the faster and easier it is to start the hot tub.

Recommendations:

• prepare a sufficiently long hose,
• check the water pressure,
• to be able to conveniently refill water in the future as well,
• take into account that the impregnation can take several tens of minutes to several hours depending on the volume of the hot tub and the water pressure.

Option 1: 230 V / 220-240 V whirlpool

Smaller or more economical whirlpools can be designed for connection to 230 V.

Typical electrical preparation:

CYKY-J 3×2.5 mm²
separate circuit breaker 1×16 A / C
current protector 30 mA

The cable includes:

L + N + PE

That is, the phase, the neutral conductor and the protective conductor.

For some models, there may be performance limitations when operating on 230 V. For example, when the massage pumps are started, the water heating can be temporarily switched off in order not to exceed the power consumption. This is especially common with hot tubs connected to one phase.

Recommendations:

• separate electrical circuit for the hot tub only,
• do not connect via an extension cable,
• do not connect to a regular garden socket without verification,
• use a 30 mA current protector,
• bring the cable to the technological part of the hot tub,
• leave a reserve of cable at least 2-3 meters.

Option 2: 400 V / 380-400 V hot tub

Larger hot tubs or hot tubs with higher output usually connect to 400 V.

Typical electrical preparation:

CYKY-J 5×2.5 mm²
separate circuit breaker 3×16 A / C
current protector 4P 30 mA

The cable includes:

L1 + L2 + L3 + N + PE

That is, three phases, a neutral conductor and a protective conductor.

For more powerful hot tubs, longer cable runs or higher protection, a stronger cable may be required, for example:

CYKY-J 5×4 mm²

The advantage of connecting to 400 V is better distribution of power between phases and less restriction of operation. In some models, the 400 V hot tub can handle the water heating and the massage pumps at the same time, while the 230 V version may have limited operation.

Recommendations:

• separate electrical circuit for the hot tub only,
• circuit breaker according to the power consumption of the specific hot tub,
• current protector 30 mA,
• bring the cable to the technological part of the hot tub,
• leave a reserve of cable at least 2-3 meters,
• entrust the connection to a qualified electrician.
