3.5. Electrical connections

ATTENTION
-This equipment cannot be connected to a normal plug.
-This equipment requires suitable electrical installation. This should be done by a specialised fitter following local electrical safety regulations of each country.
-The electrical input of the Spa should always be protected by a highly sensitive differential. A 30 mA differential is recommended.
-Earthing connection is essential.
-Use a suitable section cable bearing in mind the power of the Spa and distance to the control panel.
-Always follow instructions given in the Safety Warnings chapter of this manual.

WARNING- RISK OF ELECTRIC DISCHARGE
-The electrical supply should be switched off (differential in the OFF position or disconnect the cable from the mains) before carrying out any work.
-Never try to access an electrical component unless you are qualified or are the Head of Maintenance.
-Always use suitable personal protection equipment and tools when handling electrical equipment.
-Never access electrical elements if you are wet, particularly if you have wet feet
-Do not connect the electrical equipment (differential in the ON position), if the Spa is empty of water.

SPA CONNECTION STEPS

Locate the electrical panel of the Spa.

Locate the electrical control panel; to do this, open the side panel to access the electrical components.

Open the electrical box.

Connect the spa’s electrical control panel to the diferential switch.

INSTALLATION OF THE DIFFERENTIAL

The electrical installation should incorporate a high-sensitive 2-pole differential in the general mains input panel (the differential is not supplied with the Spa).

WARNING
It is essential that the owner of the Spa tests the differential switch at least once a month, to check its good working order.
Check that the differential is in the OFF position. Do not place the differential in the ON position until the Spa is filled with water.

CONNECT THE ELECTRICAL CONTROL PANEL TO THE DIFFERENTIAL

SWITCH

Before carrying out any work on the Spa, make sure it is disconnected from the mains (differential switch in the OFF position, or disconnect the cable from the mains).

Use a suitable cable from the differential switch to the electric cabinet of the Spa, depending on the location and applicable law. The cable section will vary depending on the Spa model and the distance of the installation.

The required kW are indicated in the appendix Technical Specifications of the Spa. The maximum power must be considered, depending on the “High Amp” or “Low Amp” configuration.

DIP Switch Functions

Fixed-Function DIP Switches

A1 Test Mode (normally off).

A2 In “ON” position, add one high-speed pump (or blowe) with Heater.

A3 In “ON” position, add two high-speed pumps (or 1 HS Pump and Blower) with Heater.

A4 In “ON” position, add four high-speed pumps (or 3 HS Pumps and Blower) with Heater.

A5 In “ON” position, enables Special Amperage Rule B. See Special Features section under Configuration Options for functionality with your system. In “OFF” position enables Special Amperage Rule A.

A6 Persistent memory reset (Used when the spa is powering up to restore factory settings as determined by software configuration).

A2, A3 and A4 work in combinatio to determine the number of high-speed devices and blowers that can run before the heat is disabled. f.e. A2 and A3 in the ON position and A4 in the OFF position will allow the heater to operate with up to 3 high-speed pumps (or two HS Pumps and Blower) runing at the same time. Heat is disabled when the fourth high-speed pump or blower is turned on.

Note: A2/A3/A4 all ogg = No heat with any high-speed pump or blower.

Assignable DIP Switches

A7 In “ON” position, enables a 5-minutes cool down for some gas heaters (Cooling Time B). In “OFF” position, enables a 1-minute cool down for electric heaters (Cooling Time A).

Undesignted switches are not assigned a function.

The Electric Specification Sheet attached at the end of this manual indicates both the “Low Amp” and the “High Amp” power.

Nominal section of the cable in mm²

Distance

15-20 m	4	4	4	6	6	6	10	10	10	16	16

For longer distances, increase the cable section accordingly.

Some configurations may require installing 1 32A line, 2 16A lines or even one three-phase line (3 x 16A) to cover the power required by the Spa.

The different configuration options of the electrical control panel are explained further on in this Installation Manual.

Remember that the installation and any changes in the electric configuration must be carried out by qualified personnel, following the current regulations in each country.
The manufacturer shall not be responsible for any damage caused by an improper installation or an installation performed by non-qualified personnel.

WARNING
Pay attention to the position of the maximum consumption switch.
The Spa will not operate properly if a cable not corresponding to the distance and power of the Spa is used, and the electrical circuits may overheat which may cause an electrical accident. Always use cable with the suitable section of maximum consumption. In the event of doubt between two values, always use the cable with the greater section.

To connect the supply to the electrical panel of the Spa, locate the packing gland positioned at one end of the electrical panel.

Make sure that there is no electric current in the connection cable (differential switch in the OFF position).

Take the cable to the Spa electrical panel.

Open the cover of the electrical cabinet, insert the feed cable through the free side.

Attention: the indicated blue cable is neutral, and the brown cable indicates the line or phase.

Fasten the terminals as indicated in the following diagrams and the type of electrical supply.

THREE PHASES 400V

ATTENTION
Correct earthing is essential
The earthing circuit of the building should always be in perfect condition to guarantee the safety of Spa users. If you have any doubts on this, ensure that the earthing circuit is checked by a duly qualified person. The manufacturer will not be held responsible for possible damage caused by incorrect maintenance of the earthing circuit.

Fasten the earth cable (yellow and green) to the terminal on the outside of the control cabinet as shown in the following diagram:

WARNING
Do not connect the electricity (differential in the ON position) until the Spa is filled with water.
