take into account that night time water pressure may be
considerably higher than day time water pressure.
install a pressure reducer ahead of the appliance if necessary.
OPERATING TEMPERATURE MIN-MAX: 2-65 °C / 35-149 °F
do not install the appliance in an environment where high
ambient temperatures (e.g. unvented boiler house) or freezing
