Flush Service Operation.
Since the introduction of the Aquasave water treatment module on Contours, the
flushing frequency is different between Contour and a Profiler models. The Contour
flush service parameter is set to 250 while the Profiler flush cycle is set to 20. This
means the Profiler will flush more often than the Contour cooler.
The N-E5 module program performs a
tank flush at regular intervals
, to dilute any
salt and sediment build up as the unit is operating.
The flush service will not affect the normal pump, or fan functions of the Cooler.
The flush service timing is determined by the number of times the water has filled to
the Trident High Water Level Sensor, and then evaporated down to the Trident Low
Water Level Sensor.
After
20 tank refills
, the
Flush Service
commences.
Each sequence of 20 or 250 refills of the tank, will force another the flush service
operation, although the time between each Flush Service can vary, according to the
conditions and Cooler settings.
When the water level evaporates down to the Low Water Level Sensor for the 20th
tank re fill,
the water inlet solenoid will open and fill the tank to the high water
level, then remain open for a further 200 second period
.
The water level will continue to rise above the High Water Level Sensor, and over
flow out the drain valve / overflow pipe.
The action of the
fresh water entering, mixing and overflowing out
from the tank,
dilutes the salt and sediment ratio back to the original supply water condition.
