Windsor Zephyr manual Safety devices, Pressure controller, Low-waterthermostat, Safety thermostat

4. Safety devices

This steam cleaner has been fitted with various safety devices to provide multiple protection measures. The most important safety components are described below.

4.1 Pressure controller

The pressure controller maintains the boiler pressure at as constant a level as is possible while the cleaner is in use. The heater is switched off when the operating pressure inside the boiler reaches its maximum of 3.2 bar, and switched on again when the pressure drops as a result of steam being drawn off.

4.2 Low-water thermostat

As the water inside the boiler is consumed, the temperature around the heater rises. The low-water thermostat switches the heater off, and the red low- water warning lamp lights up. The heater is prevented from switching on again until the boiler has cooled down, or it has been refilled with water.

4.3 Safety thermostat

If the low-water thermostat fails and the cleaner overheats, then the safety thermostat switches the whole unit off. Contact your authorized WINDSOR Customer Service agent so that the safety thermostat can be reset.

4.4 Safety cap

The safety cap seals off the boiler and keeps the steam pressure inside. If the pressure controller becomes defective, and the pressure inside the boiler rises above 5.5 bar, an overpressure valve opens inside the safety cap, and steam escapes into the open. Contact your authorized WINDSOR Customer Service agent before using the cleaner again.
