An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare
wire. It can also provide some protection against electrical fires. RCDs offer
a level of personal protection that ordinary fuses and circuit-breakers cannot
If your hot tub (typically ‘Plug & Play* spas) has an RCD plug attached and before using your spa it is recommended that you carry out an RCD test on the plug of the spa. *Plug and play means that there is no additional electrical installation required to
setup your spa. These hot tubs plug into a normal wall socket. Attached to the plug is a fitted RCD to protect the spa and the electrical circuit from unforeseen circumstances. Ensure that the spa is the only load on the circuit when plugged in.
Note: Please check the plug and wiring before plugging in for any damage – if damaged contact dealer – Never run spa with bare wires showing.
WARNING: RISK OF ELECTRIC SHOCK. The RCD plug must be tested before each use. Do not use if RCD test fails.
WARNING: Before inserting the plug into a power outlet, make sure the current rate of the power outlet and the fixed wiring are suitable for the control unit. If in doubt contact a
qualified electrician. If the following steps 1,2,3,4 are successful, the spa pump is ready for use.
