This set includes a 0.65m shower bar, a 160cm shower hose, a shower head holder, and a hand shower with two spray patterns.

Safety Information
- Always ensure the water supply is turned off before attempting any installation or maintenance.
- Installation should be performed by a qualified professional if you are unsure.
- The Ecostat 1001 CL thermostat features an adjustable scald protection set at approximately 40°C for user safety. This prevents accidental setting of excessively hot water temperatures.

The thermostat includes a safety stop feature, typically set at 40°C, to prevent scalding by limiting the maximum water temperature.

Operating Instructions
Thermostat Operation
- Temperature Control: Use the temperature handle on the Ecostat 1001 CL thermostat to set your desired water temperature. The integrated safety stop prevents temperatures above 40°C unless manually overridden.
- Flow Rate Control: The thermostat ensures economical water consumption (e.g., max. 10 l/min). To increase the flow rate beyond this, press the EcoStop button and turn the handle further. This deactivates the save function, allowing a maximum flow rate of 14 l/min.

Adjust the thermostat handle for precise temperature and flow control, enhancing showering comfort.
Hand Shower Spray Patterns
The Crometta Vario 100 hand shower offers two distinct spray patterns:
- Rain: A strong, full rain shower ideal for thorough rinsing and daily use.
- IntenseRain: A concentrated, powerful cascade that revitalizes and invigorates.
To switch between spray patterns, simply rotate the spray disc on the hand shower.

Choose between the gentle Rain spray and the invigorating IntenseRain spray by adjusting the shower head.

Simple manual selection allows for easy switching between the two spray modes.
Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your hansgrohe shower set.
- Cleaning Surfaces: Clean chrome surfaces with a soft cloth and a mild, non-abrasive cleaning agent. Rinse thoroughly with water and dry with a soft cloth to prevent water spots.
- QuickClean Feature: The hand shower nozzles are equipped with QuickClean technology. Limescale deposits can be easily removed by gently rubbing the silicone nozzles with your finger.
- Shower Hose: The Comfortflex shower hose is designed with pivot connectors to prevent tangling. Clean the hose regularly to maintain hygiene.
Troubleshooting
If you encounter issues with your shower set, please refer to the following common solutions:
- Low Water Pressure: Check if the main water supply valve is fully open. Inspect the shower head nozzles for limescale buildup and clean them using the QuickClean feature.
- Inconsistent Water Temperature: Ensure the hot and cold water supplies are correctly connected. If the thermostat is not maintaining temperature, it may require professional inspection or recalibration.
- Leaks: Check all connections for tightness. If leaks persist, turn off the water supply and consult a qualified plumber.
For persistent problems, contact hansgrohe customer support or a certified plumber.
