LOW PRESSURE RESTART
This function is included only in commercial (C-) models.
In commercial applications it is common that the water purier operates automati-
cally towards a connected external equipment. An alarm stop may cause troubles
before it is noticed by the user.
The reason for the alarm is sometimes a temporary pressure drop in the inlet water
pressure. Examples could be roadwork, momentaneous high water consumption
near the the installation, mistake by a co-worker to close the water supply etc.
The purpose of this function is to avoid these unnecessary alarms, and allow the
product to automatically restart after an alarm from low inlet pressure.
The water purier will make three attempts to restart: After 3 minutes, 20 minutes
and nally 4 hours. If the pressure is not sufcient after three attempts the water
purier stop permanentely.
