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 flow 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 fluctuations in
voltage and water pressure.
The power rating of the appliance can be selected as either 9.6kW or 7.2kW at 240V 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.
