Installation of the whirlpool tub must be carried out in accordance with national and local electrical installation regulations. The electrical installation should always be done by an authorised expert. Every Villeroy & Boch whirlpool tub is manufactured and tested according to certain standards that ensure the highest possible protection against electric shock. A faulty electrical connection can impair the operational safety of the whirlpool tub, which could lead to electric shock, injury or death. Furthermore, a faulty electrical connection can lead to maloperation of the whirlpool equipment and a risk of fire.

Important technical information

Electrical voltage: Definitions

The term 120V stands for the voltage range 110 – 120V and the term 230V for the voltage range 220 – 240V.

Cable connections: The unit must be permanently connected (with the exception of the American / Canadian models with 120V~/60Hz connected by cable).

Circuit diagrams: In addition to the information given below, please pay attention to the respective circuit diagrams (120V~/60Hz, models connected by cable; 120V~/60Hz, permanently connected models; 230V~/60Hz, permanently connected models or 230V~/50Hz, permanently connected models).

Cross-section and type of power supply cable: The cross-section of the required power supply cable to the whirlpool tub depends on the length of the cable and should be determined by a qualified electrician. Installation must be carried out in accordance with national and local electrical installation regulations. Copper cable must be used for the wiring. Aluminium cable must not be used.

Location of the whirlpool tub

High-voltage power lines (above-ground lines): You must install the whirlpool tub both horizontally and vertically at the stipulated minimum distance from all power lines in accordance with valid national and local electrical installation regulations.

Main switch: A shut-off device must be fitted in the whirlpool tub cabling, depending on the region where you live and in accordance with valid national and local electrical installation regulations. A residual current circuit breaker can be used instead of a main switch, provided it meets the same requirements and the valid national and local electrical installation regulations permit this.

Power sockets, switches and devices: You must install the whirlpool tub at the stipulated minimum distance from all power sockets, switches and electrical devices in accordance with valid national and local electrical installation regulations.

Earth connection: The control system inside the equipment compartment of the whirlpool tub must be connected to all metal devices, railings, housings and pipes/lines located within the stipulated maximum distance in accordance with valid national and local electrical installation regulations. The earth connection must be connected to earth on the outside of the control system box and all above-mentioned metal parts.

Access to the equipment compartment: Make sure the whirlpool tub is positioned so that the equipment compartment is freely accessible.

Residual current circuit breaker: All whirlpool tubs and corresponding electrical components must be protected by means of a residual current circuit breaker at the main fuse box or main switch in accordance with valid national and local electrical installation regulations.

WARNING: Removing or bypassing the residual current circuit breaker makes the whirlpool tub unsafe to use and voids the warranty. When the residual current circuit breaker is installed, all conductors with the exception of the green protective earth conductor, incl. the neutral conductor, must be run through the residual current circuit breaker. It is essential that the neutral conductor is not bypassed. Bypassing the neutral conductor produces a current imbalance, which triggers the residual current circuit breaker. Also refer to the circuit diagram of the residual current circuit breaker or contact Villeroy & Boch, LC or your authorised Villeroy & Boch specialist dealer.

STIPULATED TEST PROCEDURE: After filling the whirlpool tub and using it for the first time, and before each use, the residual current circuit breaker should be tested as follows:

Step 1: Press the Test button on the residual current circuit breaker. The whirlpool tub should then stop operating.

Step 2: Press the Reset button after 30 seconds and check whether the power supply to the whirlpool tub is restored.

If the residual current circuit breaker does not react as described above, there could be a malfunction and thus a risk of electric shock. In this case, switch off the residual current circuit breaker and only use the whirlpool tub again when the malfunction has been rectified by a qualified electrician or your authorised Villeroy & Boch specialist dealer.

Separate circuit breaker: The electrical supply to the whirlpool tub must be equipped with a suitable switch or circuit breaker. No matter whether it is a whirlpool tub with 120V~/60Hz connected by cable or a permanently connected whirlpool tub with 120V~/60Hz, 230V~/60Hz or 230V~/50Hz, the switch may only be used for the power supply to the whirlpool tub and not for the power supply to other power sockets, units or devices.

Cable duct: Every Villeroy & Boch whirlpool tub has a cable duct in which the power supply lines to the control system box are routed. The cable duct is located at the front left-hand corner of the whirlpool tub (when standing in front of the whirlpool tub control panel).

A maximum of 12V in current carrying parts: The voltage in current carrying parts accessible to the user must not exceed 12V.

Conversion to 230V~/60Hz 30A: If a current of 50A is not available, an authorised Villeroy & Boch specialist dealer or electrician can simply convert your whirlpool tub to operation at 30A (conversion instructions are in the control system box). Please note that a whirlpool tub that has been converted to operation at 30A can only heat up water when pump 1 is running at a low speed, not at a high speed. This restriction is acceptable for most climates and for inside use.

Conversion options for operation at 230V~/50Hz: If a current of 32A is not available, an authorised Villeroy & Boch specialist dealer or electrician can simply convert your whirlpool tub to a single or two-phase supply with 16A x 2. Conversion instructions for the following configurations are in the control system box of the whirlpool tub.

230V~/50Hz 16A single-phase supply: Please note that a whirlpool tub that has been converted to operation at 16 A can only heat up water when the circulation pump is running at a low speed, not at a high speed. This restriction is acceptable for most climates and for inside use.

230V~/50Hz 16A two-phase supply: Operation of the whirlpool tub is the same as when using a single-phase 32A supply, apart from the supply being split into two separate 16A supplies.

400V~/50Hz 16A x 30, supply with 3 separate neutral conductors: Operation of the whirlpool tub is the same as when using a 32A supply, however, the supply is split into three separate 16A supplies with three separate neutral conductors.

New installation and reinstallation: This information applies to both new installations and reinstallations (when, for example, a whirlpool tub is repositioned or taken to a new location).

120V~/60Hz or 230V~/60Hz voltage transformer

Whirlpool tubs with one pump can be equipped with a voltage transformer (model BF03). The BF03 transformers allow the whirlpool tub to be operated with a 120V~/60Hz or 230V~/60Hz supply, depending on the pump that is installed.

120V~/60Hz pump: Whirlpool tubs that are equipped with a 120V~/60Hz pump can be connected by cable at 120V~/60Hz or permanently connected at 120V~/60Hz or 230V~/60Hz.

120V~/60Hz, connected by cable: This option is only possible if the whirlpool tub was ordered with a 120V~/60Hz pump and a 120V~/60Hz power cable. If the whirlpool tub is connected to a power cable from a different manufacturer, it may no longer be safe and thus void the safety certification and warranty. Whirlpool tubs connected by a cable are already converted to operation at 120V~/60Hz at the factory and are supplied with a 4.57 m long standard power cable (maximum permissible length), which is connected to the whirlpool tub. This factory-installed power cable is equipped with a residual current circuit breaker.

IMPORTANT: In order to prevent hazards, cables are only allowed to be replaced with special cable sets that are obtainable from the manufacturer, his service partner or other similarly qualified persons.

In the case of whirlpool tubs with 120V~/60Hz connected by a cable, the factory-installed power cable with an integrated residual current circuit breaker must be connected to its own earthed single-phase electric circuit/power socket with 120V~/60Hz and 20A. This electric circuit may only be used for the whirlpool tub and no other electrical devices, otherwise the whirlpool tub could malfunction. For safety reasons, the power socket to which the whirlpool tub is to be connected must be within the permissible minimum distance specified by national and local electrical installation regulations. Installation must be carried out in accordance with national and local electrical installation regulations.

Fill the whirlpool tub before switching it on: Before switching on the current, the whirlpool tub must be filled up to the recommended filling level (refer to checklist for measures to be taken before filling).

Residual current circuit breaker: The unit should be equipped with a residual current circuit breaker with a nominal tripping current of up to 30mA.

WARNING: An extension cable must not be used. Villeroy & Boch does not permit the use of an extension cable under any circumstances. Using an extension cable will void the warranty for the whirlpool equipment. In addition, this exposes the user to an additional fire hazard, risk of electric shock and danger to life and limb.

120V~/60Hz, permanent connection: If your whirlpool tub was not ordered with a 120V~/60Hz power cable, then the technical equipment is designed for operation at 230V~/60Hz (even if it is equipped with a 120V~/60Hz pump). The whirlpool tub equipment must be converted from the 230V~/60Hz configuration to a 120V~/60Hz configuration before connecting the whirlpool tub to 120V~/60Hz. You can find precise instructions for this conversion in the system circuit diagram in the control system box (in the equipment compartment of the whirlpool tub).

Permanently connected whirlpool tubs with 120V~/60Hz require a 3-pole (line 1, neutral conductor and earth), single-phase separate electric circuit with 120V~/60Hz, 20A protected by a residual current circuit breaker. This electric circuit may only be used for the whirlpool tub and no other electrical devices, otherwise the whirlpool tub could malfunction. Installation must be carried out in accordance with national and local electrical installation regulations.

230V~/60Hz, permanent connection: The whirlpool tub is already set up for operation at 230V~/60Hz even if it is equipped with a 120V~/60Hz pump, provided that the whirlpool tub was not ordered with a factory-connected 120V~/60Hz power cable. In this case, the whirlpool tub equipment must be converted from the 120V~/60Hz configuration to the 230V~/60Hz configuration. You can find precise instructions for this conversion in the system circuit diagram in the control system box (in the equipment compartment of the whirlpool tub).

Permanently connected whirlpool tubs with 230V~/60Hz require a 4-pole (line 1, line 2, neutral conductor and earth), single-phase separate electric circuit with 230V~/60Hz, 50A protected by a residual current circuit breaker.

This electric circuit may only be used for the whirlpool tub and no other electrical devices, otherwise the whirlpool tub could malfunction. Installation must be carried out in accordance with national and local electrical installation regulations.

230V~/60Hz pump: Whirlpool tubs equipped with a 230V~/60Hz pump must be permanently connected. 230V~/60Hz, permanent connection: Your whirlpool tub is designed for operation at 230V~/60Hz.

Permanently connected whirlpool tubs with 230V~/60Hz require a 4-pole (line 1, line 2, neutral conductor and earth), single-phase separate electric circuit with 230V~/60Hz, 50A protected by a residual current circuit breaker.
