Description
Zip InLine DEX and DBX 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.
For type DEX the required outlet temperature can be entered on a keypad
within the range 20°C to 60°C and can be read off the digital display.
For type DBX the factory set outlet temperature is 50°C and can be adjusted
inside the appliance within the range 30°C to 60°C.
Type DEX maximum inlet temperature of 70°C is suitable for use with preheated
water from solar heating systems.
