Maintenance
PoolWarden Enclosure
The enclosure can be cleaned with a soft cloth that is moist with water. Take extra care when cleaning the
clear display window. To clean the display window make sure the cloth hasn’t been used to clean anything
else or it may have grit which may scratch the clear screen.
The PoolWarden includes cable grips on the bottom side of the box. If any are not used make sure to fill
them so that the opening is closed. If a cable grip is left open bugs may enter the inside and leave droppings
and nests which should be removed.
Sensor Maintenance
The sensors must be clean to operate properly. The strainer in front of the flow cell will catch most debris
but oils and chemical deposits will get through. Slow response, increased need to calibrate and inconsistent
readings are indicators that the sensors need to be cleaned or replaced.
To clean the sensors, turn off both valves to the flow cell and carefully remove the pH and ORP sensors
from the flow cell. The small white dots on the bottom of the sensor should be flush with the black sensor
body and clearly visible. Use a soft brush and a mild detergent to remove any oil and contamination from the
glass bulb and the small white dots. Do not let the sensors dry out as that may damage the sensor, after
cleaning apply Teflon tape to the threads and reinstall the sensors.
ORP and pH Sensor Replacement
The PoolWarden ORP and pH sensors have a warranty to last at least 1 year and will most likely last from
1.5 to 3 years or longer. An indication that it is time to replace a sensor is the percentage listed on the
calibration screen in the PoolWarden service menu. If the percentage is 99% then the sensor is not able to
be properly calibrated and should be replaced. There is a date code on the sensor body that can also aid in
determining if the sensor needs to be replaced. If one sensor needs to be replaced and both the ORP and
pH sensor have the same date code it is recommended to replace them both.

Sensor Storage
During the installation of the PoolWarden make sure to the sensor caps. To store the sensors turn off both
valves to the flow cell and remove the sensors. Add a little water to the sensor cap and hand tighten the
sensor to the cap. The cap should have a small sponge that only needs to be moistened.
Cold Temperatures
The ORP and pH sensors should not be exposed to freezing conditions. If the outside temperature is below
freezing this may damage the sensors and they should be removed to protect them. Always store them with
their protective caps.
Always drain the water from the flow cell, strainer and tubing to to flow cell to prevent damage in freezing
conditions.
