Description
Zip InLine CEX-O and CEX-U instantaneous water heaters are micro-processor controlled,
pressure resistant water heaters suitable for supplying hot water to one or more outlets.
The heating element switches on automatically when the hot water tap is opened and
switches off automatically when the hot water tap is closed.
The electronic control system automatically regulates the power consumption depending on
the supply water temperature and ow rate to achieve the required outlet temperature within
the power limit of the appliance.
Power consumption is also regulated based on outlet temperature to ensure the required
temperature is achieved exactly to the degree and irrespective of uctuations in voltage
and water pressure.
The power rating of the appliance can be selected as either 8.8kW or 6.6kW at 230V at the
time of installation.
The required outlet temperature can be entered on a keypad within the range 30°C to 55°C
and can be read off the digital display.
The maximum inlet temperature of 70°C is suitable for use with preheated water e.g. from
solar heating systems.
