Maintenance of the sen‐
sors
pH and ORP sensors are maintenance-free
and need to be replaced when they are no
longer operating perfectly. Having said that, the
good physical state of the sensors needs to be
checked regularly.
1.
Check whether there is dirt or reside on
the heads of the sensors.
2.
Do so by regularly calibrating the
sensors and replace them when they
can no longer be calibrated.
3.
Remove the sensors during long opera‐
tional pauses (e.g. over-wintering) and
store the sensors in their original pack‐
aging. Do not forget to pour water, or
even better water from the pool, into the
sensor cover.

Maintenance
After extended periods of idleness
If the peristaltic pump has not pumped gaseous
or adhesive feed chemicals for a longer period
of time, checked whether the state of the hoses
permits reliable operation.

ness
Shorter maintenance intervals may be neces‐
sary depending on the feed chemicals used
and operating conditions.
Approx. annually
Replace the pump hose.
This can lead to a reduction in pump
capacity over time depending on the
operating conditions. Therefore replace
the pump hose earlier if necessary.
The power end is maintenance-free.
