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

We recommend leaving access of at least:

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

The most important access is to the section where the following are located:

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

If the hot tub is recessed into a terrace or built around, it is necessary to prepare service doors or removable panels.

The hot tub should never be built in so that the technology cannot be accessed. In the event of a fault, the terrace or cladding would then have to be dismantled.

The hot tub must stand on a solid, level and stable surface.

An ideal base is, for example:

• a concrete slab,
• a reinforced terrace,
• paving on a high-quality base,
• a solid base prepared for a high load.

It is important to remember that a filled hot tub can weigh more than 1,500-2,500 kg depending on the model size, water and number of people.

The surface must be:

level, load-bearing, stable and must not sink over time.

We do not recommend placing the hot tub directly on grass, soil, uncompacted gravel or a soft surface.

Before the hot tub is delivered, it is necessary to check that it can be moved to the installation site.

We recommend checking:

• gate width,
• path width,
• stairs,
• passages around the house,
• height differences,
• possibility of using handling equipment.

Hot tubs are large and are often transported on their side. If access is complicated, more people, special handling equipment or a crane may be required.

Before installation, we recommend ensuring the option of quickly filling the hot tub.

Ideally, you should have nearby:

a 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,
• make sure water can be conveniently topped up in the future,
• bear in mind that filling can take from several dozen minutes to several hours depending on the hot tub volume and water pressure.

Option 1: Hot tub for 230 V / 220-240 V

Smaller or more energy-efficient hot tubs may be designed for connection to 230 V.

Not recommended for LOVIA L301

Typical electrical preparation:

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

The cable contains:

L + N + PE

That is phase, neutral conductor and protective conductor.

Some models may have performance limitations when operated on 230 V. For example, when the massage pumps are started, the water heating may temporarily switch off to prevent the power input from being exceeded. This is common mainly with hot tubs connected to a single phase.

Recommendations:

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

Option 2: Hot tub for 400 V / 380-400 V 

Recommended solution for LOVIA L301 

Larger hot tubs or hot tubs with higher performance are usually connected to 400 V.

Typical electrical preparation:

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

The cable contains:

L1 + L2 + L3 + N + PE

That is three phases, neutral conductor and protective conductor.

For more powerful hot tubs, longer cable routes or higher circuit breaker ratings, a stronger cable may be required, for example:

CYKY-J 5×4 mm²

The advantage of a 400 V connection is better distribution of power between phases and fewer operating limitations. With some models, a hot tub on 400 V can handle water heating and massage pump operation at the same time, while the 230 V version may have limited operation.

Recommendations:

• a separate electrical circuit only for the hot tub,
• circuit breaker according to the power input of the specific hot tub,
• 30 mA residual current device,
• bring the cable to the technical part of the hot tub,
• leave a cable reserve of at least 2-3 metres,
• entrust the connection to a qualified electrician.
