12.8 LOW FLOW ALARM
Should the ChloroMatic Nipper flow switch register a flow rate below 3.6m3/h (60L/min), the ChloroMatic
Nipper will enter
LOW FLOW ALARM
:

In

, the ChloroMatic Nipper will not produce chlorine. Once the flow switch registers flow
above 3.6m

/h (60L/min), the ChloroMatic Nipper will return to normal operation. To achieve best efficiency,
the ChloroMatic Nipper cell should be installed such that turbulent water is limited as much as possible.
Do not install a 90° elbow closer that 200mm from the cell’s inlet barrel union. Isolation valves used where
equipment is located below pool water level, should also be installed no closer than 200mm from inlet barrel
union. This will assist laminar flow.
12.9 ADD SALT ALARM
Should the ChloroMatic Nipper register low conductivity within the cell, this could be triggered by cold water
(below 15ºC), or a salt concentration below its minimum (refer to recommended salt range section in the
manual), the ChloroMatic Nipper will enter
ADD SALT ALARM
. Additional salt may be added to overcome
a lower temperature. However, the maximum salt level should also be considered and if water temperature
drops too far, the system should be turned off.

Once the ChloroMatic Nipper registers a salt concentration within range (refer to recommended salt range
section in the manual), the ChloroMatic Nipper will return to normal operation.
12.10 LOW SALT CUT-OUT ALARM
Should the salt concentration continue to be diluted, the ChloroMatic Nipper will enter
LOW SALT CUT-OUT ALARM
.
