Correct procedure for testing the RCD (Residual Current Device)

(Before starting the test, we recommend permanently removing the protective cover film from the control panel.)
The INTEX Pure Spa hot tub is equipped with a RCD at the end of the power cable. The RCD must be tested before each use. Do not use the hot tub if the RCD is not functioning properly – disconnect the power cable until the fault is professionally repaired.

Before using the RCD (Residual Current Device)

  • The plug must always be dry. Connecting the device to a wet outlet is strictly prohibited!
  • The hot tub plug must be directly connected only to a grounded socket of a fixed electrical installation.
  • To reduce the risk of electric shock and fire, do not use extension cords, timers, adapters, or converters. Ensure the outlet is properly located.

Note: The use of extension cords is a common source of malfunctions and damage, such as burned plugs or voltage drops. Additionally, consider the safety risks associated with using an extension cord. The use of extension cords is prohibited – see the manufacturer's user manual.
