* Note: the shower will continue to operate on
a reduced heat setting if the running pressure
falls to 0.7 bar (1.2 bar for 10.5kW), there
will be a noticeable reduction in flow and
temperature from the showerhead.
If the stated flow rates are not available, it
may not be possible to achieve optimum
performance from the unit throughout the year.
During periods of high ambient temperatures
it may be necessary to select the economy
