2.1 Included Components:

  • 1 x Cornat Comiso Hand Shower Head
  • 1 x Water-Saving Insert
  • 1 x Seal

2.2 Installation Steps:

  1. Prepare the Connection: Ensure your existing shower hose has a standard 1/2 inch connection thread. If replacing an old shower head, unscrew it from the hose.

  4. Attach to Hose: Screw the Cornat Comiso Hand Shower Head onto your shower hose. Hand-tighten until secure. Avoid over-tightening, which can damage the threads or seal.
  5. Test for Leaks: Turn on the water supply and check for any leaks at the connection point. If leaks occur, tighten slightly or re-check the seal's placement.

The hand shower is designed for easy installation and is suitable for use with instantaneous water heaters.

3. Operation

Your Cornat Comiso Hand Shower Head offers five distinct spray modes, easily adjustable for your preferred showering experience.

The hand shower features a one-handed rotary slider located on the shower head. Simply rotate this slider to cycle through the available spray patterns:

  • Normal Jet: Provides a uniform and rich flow of water from all nozzles.
  • Soft Jet: An air-refined jet pattern for a noticeably soft and gentle water flow.
  • Massage Jet: Large, powerful jets designed for a soothing and invigorating massage.
  • Spray Jet: Creates dynamic water jets from individual nozzles, offering a fine, pearly sensation.
  • Normal/Spray Jet: A combination of the Normal and Spray jet types for a balanced experience.

3.2 Water-Saving Function:

The included water-saving insert, if installed, significantly reduces the flow rate without compromising comfort. This feature allows for water savings of up to 55%.
