Frequently Asked Questions - CWM 750 P STIEBEL ELTRON
How to install the CWM 750 P water heater?
Installation must be carried out by a qualified professional. Mount the device on the wall using the supplied wall plugs, connect the cold water inlet and hot water outlet, then connect the three-phase power supply. Follow safety distances and applicable standards.
How to adjust the water temperature?
The temperature is set via the rotary knob on the device. Turn it towards the hot symbol to increase temperature (max 60 °C) or towards cold to decrease. Actual temperature may vary depending on flow rate.
What to do if the water does not heat up?
First check the power supply (circuit breaker, fuse). Ensure the water supply is open and pressure is sufficient (1-10 bar). If the problem persists, contact an authorized Stiebel Eltron technician.
What is the power consumption of the CWM 750 P?
The device has a power of 7.5 kW. Consumption depends on usage time. For example, using hot water for 10 minutes at full power consumes about 1.25 kWh.
How to maintain the water heater?
Annual descaling is recommended, especially in hard water areas. Use a suitable descaling product or call a professional. Also clean the water inlet filter if present.
The device makes noise, is this normal?
A slight humming may be normal due to water flow. If the noise is loud or intermittent, it may indicate scale or air in the circuit. Bleed the air or descale.
Can I use the device with water pressure above 10 bar?
No, the maximum operating pressure is 10 bar. Excessive pressure may damage the device. Install a pressure reducer if necessary.
