taps. If thermostatic mixing valves or taps are to be used, their compatibility
with the instantaneous water heater must be verified under site operating
conditions.
• The appliance must be completely filled with water before being switched
on.
• Before commissioning for the first time and each time the appliance or
the piping system is emptied (e.g. due to work on the plumbing system or
maintenance), the appliance must be vented by opening and closing the
hot water tap until all air has been eliminated from the water heater and no
more air emerges, before re-connecting to the electrical supply.
• The appliance must only be used for heating wholesome (cat 1) water. The
specific water resistance must not fall below the required value indicated
on the rating plate. The appliance must not be used for any other purpose.

• The Zip InLine is intended for connection to mains supply only. In any other
case please contact Zip on 0345 6 005 005 for advice.

rate, supply voltage and incoming water temperature.
• At times of low incoming water temperature (below 12°C) it may be
necessary to reduce the flow rate through the appliance to increase the
hot water temperature.
