Pentair 42002-0024S Stack Flue Sensor Replacement NTC Temperature
Sensor For Pool and Spa Heater Electrical Systems
Specification download link : NSAB1802JD8-650T2I SPEC.pdf
Installation method download link : Stack Flue Sensor Insulation.pdf
Description
A stack flue sensor, located on the exhaust elbow of a pool heater,
prevents the flue gas output from exceeding 500°F. When this fails,
your system will show error codes E05 or E06 to indicate that the
stack flue sensor must be replaced.
This replacement stack flue sensor from Optimum Pool Technologies
is compatible with Pentair’s MasterTemp, Max-E-Therm, and other
Pentair Sta-Rite heaters. It is designed specifically to replace
the Sta-Rite heater stack flue sensor.
Location:The Indoor Stack Flue Switch (ES2)/Stack Flue Sensor (SFS) Is Located on the Exhaust Elbow.

6.1 In the process of storage and transportation, per stack height is
not more than 4 CTN products.
6.2 Available with all transport method, but avoid the rain, snow of
direct or indirect leaching and mechanical damage.
6.3 Products should be stored in the temperature of environment - 10 ℃ / + 40 ℃, relative humidity is not more than 80%, environment should not have acid, alkali and corrosion gas or radioactive source.
Attention on operation
7.1 It will bring extra heat and affect testing precision when the
current pass through the sensor, With a view to it before selecting
sensor.
7.2 When the product moves, the installation must be handled gently to
avoid damage caused by pulling the product.
7.3 Product deformation, oxidation and other phenomena, can not be
used, so as not to affect the temperature accuracy.
7.4 Excessive temperature variations should be avoided within the
operating temperature range.
7.5 Do not use in corrosive gases (such as CO2,NH3,SOX,NOX, etc.)
beyond specified conditions.
7.6 Do not use in electrolysis, salt, acid, alkaline and organic
solvents beyond specified conditions.
7.7 In the limit temperature, the product can withstand too high or
too low temperature shock in the short term, but can not put the
product in the limit temperature for a long time, in order to avoid
shortening the service life of the product.
