ELECTRICAL

Your 

CALDERA

 spa has been carefully designed to give you maximum 

safety against electrical shock. Connecting the spa to an improperly 

wired circuit will negate many of the spa’s safety features. Improper 

wiring may also cause electrocution, risk of fire, and other risks of 

injuries. Please read and follow the electrical installation requirements 

and instructions for your spa completely! Your spa must be supplied by 

a ground fault circuit interrupter - residual current device (RCD) - with a 

tripping rating not exceeding 30 mA in an electrical subpanel.

VACANZA

 SPAS MUST BE WIRED IN ACCORDANCE WITH ALL 

APPLICABLE NATIONAL AND LOCAL ELECTRICAL CODES. ALL 

ELECTRICAL WORK SHOULD BE DONE BY AN EXPERIENCED, 

LICENSED ELECTRICIAN. WE RECOMMEND THE USE OF 

APPROPRIATE ELECTRICAL CONDUIT, FITTINGS, AND WIRE FOR 

ALL CIRCUITS.
The 

MARINO

, 

CAPITOLO, CELIO

 and 

AVENTINE

  spas require a 16 

amp, single phase, 230 volt, three wire service (one line, one neutral, 

one ground). 
The 

AVENTINE

 can be converted to a 20 amp service allowing the 

high speed jet pump to operate simultaneously with the heater.  A 

CALDERA

Spa Technician must reconfigure spa using the soft jumpers 

to allow the heater to run concurrent with jet pump.
The 

PALATINO

 spa requires

 a 

 20 amp single phase, 230 volt, 

three wire service (one line, one neutral, one ground) found below. 

Additionally, one main disconnect switch with at least 3 mm separation 

between contacts must be used for all electrical circuits to the spa.
Mount the subpanel according to local codes, but not closer than 1.5 

meters (5 feet) away.

CONDUIT INSTALLATION  INSTRUCTIONS

1.  To connect the electrical service, first remove the screws from the 

equipment compartment door. Carefully pull the door panel down 

and away in order to remove it completely from the spa.

2.  Locate the control box. Loosen the screws on the front of the 

control box. Remove the screws and the control box cover.

3.  Route the electrical conduit through the access opening of the spa. 
4.  Connect the supply conduit to the control box and connect the 

wiring as detailed on the next page, or on the wiring diagram label 

on the inside of the control box cover.

WARNING

: Removing or bypassing any GFCI breaker will result in an 

unsafe spa and will void the spa’s warranty.

IMPORTANT

: Should you ever find the need to move or relocate your 

VACANZA

 spa, it is essential that you understand and apply these 

installation requirements. Your 

VACANZA

spa has been carefully 

engineered to provide maximum safety against electric shock. 

Remember, connecting the spa to an improperly wired circuit will negate 

many of its safety features.

NOTE

: Long wiring runs may require larger-gauge wire than stated.
